In this week’s article, we’re discussing a few of the changes for ICD-10-CM in the Nervous System (Chapter 6): Alzheimer’s Dementia, Epilepsy, Hemiparesis/Hemiplegia (Dominant vs. Non-Dominant), Migraine, Phantom Limb Pain and Sleep Apnea

Alzheimer’s Dementia

I-9: Alzheimer’s Dementia

• with behavioral disturbance (aggressive) (combative) (violent) (331.0 / 294.11)
• without behavioral disturbance (331.0 / 294.10)

NOTICE:

The category for Alzheimer’s disease (G30) has been expanded to reflect onset (early vs. late)

I-10: Alzheimer’s Dementia

• behavioral disturbance (G30.9 / F02.81)
• early onset (G30.0 / F02.81)
• late onset (G30.1 / F02.80)
• specified NEC (G30.8 / F02.80)

Epilepsy

Terms for Epilepsy have been updated to classify the disorder, e.g,

• Localization-related Idiopathic Epilepsy
• Generalized Idiopathic Epilepsy
• Special Epileptic Syndromes

Example:

I-9: Epilepsy, epileptic (idiopathic) (345.9)

Epilepsy, localization related (focal) (partial) and (epileptic syndromes)

• With
• Complex partial seizures (345.4)
• Simple partial seizures (345.5)

NOTICE:

Within each category, more specificity can be described to identify: Seizures of Localized Onset, Complex Partial Seizures, Intractable and Status Epilepticus.

I-10: Epilepsy, epileptic, epilepsia (attack) (cerebral) (convulsion) (fit) (seizure) (G40.909)

Epilepsy, localization-related (focal) (partial)

• Idiopathic (G40.009)
• With seizures of localized onset (G40.009)
• Intractable (G40.019)
• With status epilepticus (G40.011)
• Without status epilepticus (G40.019)
• Not intractable (G40.009)
• With status epilepticus (G40.001)
• Without status epilepticus (G40.009)

NOTE

Category G40, Epilepsy and Recurrent Seizures

The following terms are to be considered equivalent to intractable:

• Pharmacoresistent (pharmacologically resistant)
• Treatment resistant
• Refractory (medically)
• Poorly controlled

Hemiplegia and Hemiparesis  (Dominant vs. Non-Dominant Side)

This category is to be used only when the listed conditions are reported without further specification, or are stated to be old or longstanding but of unspecified cause. The category is also for use in multiple coding to identify these conditions resulting from any cause.                                      

I-9:

The following fifth-digits are for use with codes 342.0-342.9:

• 0 affecting unspecified side
• 1 affecting dominant side
• 2 affecting non-dominant side

I-10:

Per ICD-10-CM Official Coding Guidelines: Codes from category G81, Hemiplegia and hemiparesis, and subcategories, G83.1, Monoplegia of lower limb, G83.2, Monoplegia of upper limb, and G83.3, Monoplegia, unspecified, identify whether the dominant or non-dominant side is affected.

Should the affected side be documented, but not specified as dominant or non-dominant, and the classification system does not indicate a default, code selection is as follows:

• For ambidextrous patients, the default should be dominant
• If the left side is affected, the default is non-dominant
• If the right side is affected, the default is dominant

Example: G81.9 Hemiplegia, unspecified

• G81.90:  Hemiplegia, unspecified affecting unspecified side
• G81.91:  Hemiplegia, unspecified affecting right dominant side
• G81.92:  Hemiplegia, unspecified affecting left dominant side
• G81.93:  Hemiplegia, unspecified affecting right non-dominant side
• G81.94:  Hemiplegia, unspecified affecting left non-dominant side

            Excludes1: Hemiplegia and hemiparesis due to sequela of cerebrovascular disease

Migraine

I-9: Migraine, Unspecified (Idiopathic) (346.9x)

I-10: Migraine, Unspecified (Idiopathic) (G43.909)

NOTE

Category G43, Migraine

The following terms are to be considered equivalent to intractable:

• Pharmacoresistent (pharmacologically resistant)
• Treatment resistant
• Refractory (medically)
• Poorly controlled

Phantom Limb

The sensation that an amputated or missing limb is still attached to the body and is moving along with other body parts. An estimated 60% to 80% of people that have had an amputation, experience phantom sensations in the amputated limb with the majority being painful.  

I-9: Phantom limb (syndrome) (353.6)

NOTICE:

I-10 has given us the ability to identify whether pain is present or not after an amputation.

I-10: Phantom limb syndrome (G54.7)

• with pain (G54.6)
• without pain (G54.7)

Sleep Apnea

Sleep Apnea has its own subcategory with fifth character specificity identifying the type

Example:      

I-9: Sleep Apnea, Unspecified (780.57)

• with
• Hypersomnia, unspecified (780.53)
• Hyposomnia, unspecified (780.51)
• Insomnia, unspecified (780.51)
• Sleep disturbance (780.57)
• Central, in conditions classified elsewhere (327.27)
• Obstructive (adult) (pediatric) (327.23)
• Organic (327.20)
• other (327.29)
• Primary central (327.21)

I-10: Sleep Apnea, Unspecified (G47.30)

• Central (primary) (G47.31)
• in conditions classified elsewhere (G47.37)
• Obstructive (adult) (pediatric) (G47.33)
• Primary central (G47.31)
• Specified NEC (G47.39)

As you can see, there are several new terms and descriptions in the Nervous System Chapter for I-10-CM, providing more specificity and better clarity of certain conditions. If we can take just a little extra time assigning diagnosis codes for I-10, we will reflect the true severity of illness (SOI) for each and every patient.

All Medicare discharges from acute Inpatient Prospective Payment System (IPPS) hospitals are not created equal. Specifically, hospitals must determine whether the patient was “discharged” or “transferred” from the hospital.

In May, the Office of Inspector General (OIG) released the report, Medicare Inappropriately Paid Hospitals’ Inpatient Claims Subject to the Postacute Care Transfer Policy.

This was not a new type of review for the OIG. In prior similar reviews, the OIG found issues and made the following recommendations to the Centers for Medicare and Medicaid Services (CMS):

• Recommend that CMS provide hospitals education regarding the transfer policy
• Require Medicare Administrative Contractors (MACs) to put edits in place to “prevent and detect postacute care transfers that are miscoded as discharges.”

In spite of prior OIG reviews and recommendations, the OIG once again found in more recent reviews that hospitals not complying with the policy received approximately $12.2 million in overpayments from Medicare contractors. In the May report, the OIG once again conducted a review with the objective of determining if appropriate payments were being made to hospitals by Medicare for claims subject to the postacute care transfer policy. Before examining the report findings, I believe it is important to first have a basic understanding of Medicare’s Postacute Transfer Policy.

Postacute Care Transfer (PACT) Policy Background

• This policy was established by CMS effective October 1, 1998.
• The purpose of this policy is to prevent Medicare from having to pay twice for the same care: once to the hospital as a MS-DRG payment and second to a postacute facility or level of care.
• This policy distinguishes between beneficiary “discharges” and “transfers” from IPPS hospitals.
• A discharge status code is required by CMS for all inpatient claims. This two-digit code determines whether Medicare pays for a “discharge” or a “transfer.”
• Full Medicare Severity Diagnosis-Related Group (MS-DRG) payments are made for inpatient “discharges” to home or certain types of health care institutions.
• A per diem rate is paid for each day of the stay for “transfers.” This amount is not to exceed the full MS-DRG payment made for discharges to home.
• A “transfer” MS-DRG rate is paid for Medicare inpatients who have a qualifying DRG and one of the following discharge status codes assigned:

(Source: MLN Matters Number: SE0801at: https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNMattersArticles/downloads/SE0801.pdf)

How CMS determines what DRGs will be Transfer DRG:

• The DRG has a least 2,050 total postacute care transfer cases;
• At least 5.5 percent of the cases in the DRG are discharged to postacute care prior to the geometric mean length of stay (LOS)for the DRG;
• The DRG must have a geometric mean LOS greater than 3 days; and
• If the DRG is a paired set based on the presence/absence of a comorbidity or complication, both paired DRGs are included if either one meets the first three criteria.

Again, the May OIG Report was conducted to determine if inpatient claims subject to the postacute care transfer policy were being appropriately paid by Medicare. The OIG reviewed Medicare beneficiary transfers to postacute care with dates of service from January 2009 through September 2012. Specific claims were identified through data analysis. Specific OIG findings and recommendations are as follows:

OIG Findings by the Numbers:

• 6,635: The number of inappropriately paid claims by Medicare for claims subject to the postacute care transfer policy.
• 91%: The percentage of inappropriately paid claims where the inpatient hospitalization was followed by claims for home health services.
• $19,471,432: The amount Medicare overpaid to hospitals due to Common Working File (CWF) edits related to home health care, SNFs, and non-IPPS hospital not working properly.
• $31.7 million: The approximate amount of money that Medicare could have saved over 4 years if it had had controls to ensure that the Common Working File (CWF) edits were working properly.

OIG Recommendations to CMS:

• “Direct the Medicare contractors to recover the $19,471,432 in identified overpayments in accordance with CMS’s policies and procedures;
• direct the Medicare contractors to identify any transfer claims on which the patient discharge status was coded incorrectly and recover any overpayments after our audit period;
• correct the CWF edits and ensure that they are working properly; and
• educate hospitals on the importance of reporting the correct patient discharge status codes on transfer claims, especially when home health services have been ordered.”

What the Hospital Needs to know:

“The Federal Register emphasizes that the hospital is responsible for coding the bill on the basis of its discharge plan for the patient. If the hospital subsequently determines that postacute care was provided, it is responsible for either coding the original bill as a transfer or submitting an adjusted claim.”

63 Fed. Reg. 40954, 40980 (July 31, 1998). See also MLN Matters Number: SE0408.

There were no changes made to the Post-Acute payment policy for the current 2014 CMS Fiscal Year that goes from October 1, 2013 through September 30, 2014. A complete list of applicable DRGs can be found in Table 5 of the IPPS Final Rule.

Specific detail regarding the PACT policy can be found in the Code of Federal Regulations (CFR) Title 42: Public Health §412.4 Discharges and transfers.

Have you ever questioned whether a patient actually has a UTI or not, based on the clinical signs and symptoms documented in the medical record, even if “UTI” is documented by the physician? In this week’s article, we'll be discussing UTIs in more specified detail to help with this very issue, as well as CKD.

UTI

Lab Results

We all should be aware that urine cultures growing greater than 100,000 colony forming units (CRU/mL) usually indicates that an infection is present.

Sometimes an infection, if symptoms are present, may be indicated with lower numbers (1,000 to 100,000 CFU/mL).

If a patient has a urine sample collected with a catheter, which minimizes contamination, results of 1,000 to 100,000 CFU/mL may be considered significant.

Symptoms of a UTI

• Painful urination
• Frequent urination
• Urine that is cloudy, bloody, or has an odor
• Pain and pressure in the pubic bone area (women) and rectal pressure (men)
• Feeling of a full bladder but only have drops of urine on urination
• Tiredness
• Weakness
• Fever if the UTI has spread to the kidneys or blood
• Fever is not common with a UTI of the lower urinary tract (urethra or bladder)

NOTE FROM 2Q Coding Clinic, page 20

The provider must clearly document the causal relationship between the UTI and catheter. A coder cannot automatically assign a Catheter-Associated Urinary Tract Infection (CAUTI) when the patient has an indwelling catheter and then develops a UTI.

However, preventing and tracking CAUTIs is very important so if a patient has an indwelling catheter and a UTI, the coder should query the provider as to the cause of the UTI. This information should be documented in the record, as well.

UTI’s in the Elderly

TIP

Look for catheter use in the elderly.

Symptoms can appear non-specific and a diagnosis may be more difficult to determine in the elderly population and/or for those patients in healthcare settings requiring long-term catheter use.

UTI Due to a Catheter--See Complication, catheter, urethral, indwelling, infection and inflammation in the alphabetic index.

• ICD-9--(996.64)
• ICD-10—(T83.51X_) (seven characters)
• initial encounter
• subsequent encounter
• sequela

Contaminant

Remember, if a UTI is documented and the urine sample grows >100,000 colonies, but is labeled as contaminated, no UTI code is reported.

Something You May Not Know

• Females get UTIs more frequently than males.
• For patients that have frequent UTIs, their bacteria may become resistant to antibiotics over time.
• Patients may be more prone to recurring UTIs if the following are present:
• Kidney disease
• Diseases that affect the kidneys, i.e. Diabetes, Hypertension, etc.
• Compromised immune systems

Chronic Kidney Disease

Chapter 14: Disease of Genitourinary System (I-10)-Coding Guidelines

(Unless otherwise indicated, these guidelines apply to all health care settings)

1. Stages of chronic kidney disease (CKD)
   
   The ICD-10-CM classifies CKD based on severity. The severity of CKD is designated by stages 1-5. Stage 2, code N18.2, equates to mild CKD; stage 3, code N18.3, equates to moderate CKD; and stage 4, code N18.4, equates to severe CKD. Code N18.6, End stage renal disease (ESRD), is assigned when the provider has documented end-stage-renal disease (ESRD).
   
   If both a stage of CKD and ESRD are documented, assign code N18.6 only.
   
   
2. Chronic kidney disease and kidney transplant status
   
   Patients who have undergone kidney transplant may still have some form of chronic kidney disease (CKD) because the kidney transplant may not fully restore kidney function. Therefore, the presence of CKD alone does not constitute a transplant complication. Assign the appropriate N18 code for the patient’s stage of CKD and code Z94.0, Kidney transplant status. If a transplant complication such as failure or rejection or other transplant complication is documented, see section I.C.19.g for information on coding complications of a kidney transplant. If the documentation is unclear as to whether the patient has a complication of the transplant, query the provider.
   
   
3. Chronic kidney disease with other conditions
   
   Patients with CKD may also suffer from other serious conditions, most commonly diabetes mellitus and hypertension. The sequencing of the CKD code in relationship to codes for other contributing conditions is based on the conventions in the Tabular List.

See I.C.9. Hypertensive chronic kidney disease

See I.C.19. Chronic kidney disease and kidney transplant complications

NOTE FROM 3Q Coding Clinic, page 3

Complications of a transplanted organ are assigned when the transplanted organ is being rejected by the recipient or there are other complications or diseases of the transplanted organ. Ex: A patient develops Acute Renal Failure after a transplant. If the post-transplant condition affects the function of the transplanted organ, two codes are required. One for the Complication of the Transplanted Organ (996.81) (T86.12), which is sequenced as the principal diagnosis, and a second code describing the Acute Renal Failure (584.9) (N17.9).

Pre-existing conditions or medical conditions that develop after a transplant are coded as Complications of the Transplanted Organ only when they affect the function of that organ.

Status code V42.0 should only be used if there is no complication of the organ replaced. A V42.x status code is never used in conjunction with a (996.8x) code if there is no complication of the same transplanted organ.

Sometimes there are no easy solutions when it comes to coding. After all record documentation has been thoroughly reviewed and analyzed there may be only one solution left. When in doubt, query the physician. The worst that can happen is the physician says ‘no’, right?

Appending modifier 59 to a procedure code on an outpatient claim may result in Medicare payment when the code would not have received payment without the modifier. This is a good thing if the modifier is used appropriately for the correct circumstances. But modifier 59 is often misused and this could be a compliance concern for your hospital. Understanding CCI edits and correct modifier usage is critical for compliant billing.

The healthcare industry has been dealing with the National Correct Coding Initiative policy (NCCI or CCI) and edits for over 15 years now, but correct billing and modifier usage continues to be difficult and confusing for a lot of providers. One of the most commonly used and misused modifiers is modifier 59 which identifies a distinct procedural service. In fact misuse of this modifier is such a problem, that CMS has repeatedly provided education, clarification, and examples on the proper use of modifier 59. Last week, they released a new MLN Matters Article, SE1418 that again clarifies the appropriate use of modifier 59.

First, let’s look at some general information about the CCI edits:

• They were developed to promote national correct coding methodologies and to control improper coding leading to inappropriate payment in Part B claims
• They are based on coding conventions defined in the American Medical Association's CPT Manual, national and local policies and edits, coding guidelines developed by national societies, analysis of standard medical and surgical practices, and a review of current coding practices.
• The NCCI edits are updated quarterly and the NCCI Policy Manual is updated annually. The policy manual explains the rationale for the edits, the correct usage of modifiers, and specific policies for certain code pairs.
• The edits began in 1996 for Part B claims, and in 2000 for hospital claims. The Part B and hospital edits are not exactly the same.
• Procedure-to-Procedure (PTP) edits define when two HCPCS/CPT codes should not be reported together either in all situations or in most situations.
• A Correct Coding Modifier Indicator (CCMI) of “0” indicates the two codes should never be reported together by the same provider for the same patient on the same day of service. A CCMI of “1” indicates the codes may be reported together only in defined circumstances which are identified on the claim by the use of specific NCCI-associated modifiers.

“Modifier 59 is used to identify procedures/services, other than E/M services, that are not normally reported together, but are appropriate under the circumstances. Documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual.” Modifier 59 should only be used if there is not another modifier that could be used to explain the circumstances. Modifier 25, not 59, is used to indicate separate and distinct Evaluation and Management (E/M) services.

The article contains a lot of information about the correct use and inappropriate uses of modifier 59. Providers should carefully review the complete article to fully understand how to use this important modifier. Some of the common uses of modifier 59 described in the article include:

• Different anatomic sites, which includes different organs and in some cases, different lesions in the same organ. However, since CCI edits are to prevent the inappropriate billing of lesions and sites that should not be considered to be separate and distinct, modifier 59 should only be used to identify clearly independent services that represent significant departures from the usual situations. The treatment of contiguous structures in the same organ or anatomic region does not constitute treatment of different anatomic sites, for examples nails, nails beds and adjacent soft tissue; posterior segment structures of the eye; and adjoining areas in the same shoulder.
• Different patient encounters on the same day. One huge issue here is how a patient encounter is defined. Recently an NCCI coding specialist clarified that “encounter” as used in the new NCCI paragraph concerning the use of CPT code 94640 for respiratory treatment represents direct personal contact in the hospital between a patient and a physician or other healthcare professional. In other words, there may be several different encounters with a patient during a day of an extended care episode. For CPT 94640 multiple encounters on the same date of service are reported with modifier 76, but there are codes where modifier 59 would be the appropriate modifier for different encounters on the same day. Beware that this definition of “encounter” may not apply to all CCI edits or be accepted by all Medicare contractors.
• Sequential “timed code” services – this generally refers to rehabilitative therapy services which are defined in 15 minutes intervals. If the therapy services are provided sequentially for a different 15 minute interval, then modifier 59 is appropriate.
• A diagnostic service that proceeds a therapeutic service if “(a) it occurs before the therapeutic procedure and is not interspersed with services that are required for the therapeutic intervention; (b) it clearly provides the information needed to decide whether to proceed with the therapeutic procedure; and (c) it does not constitute a service that would have otherwise been required during the therapeutic intervention.” The example given is angiography preceding a revascularization if the circumstances noted above are met.
• A diagnostic procedure subsequent to a completed therapeutic procedure only when the diagnostic procedure is not a common, expected, or necessary follow-up to the therapeutic procedure. For example, a chest x-ray after a chest tube insertion to verify placement is not appropriate for modifier 59, but a chest x-ray after a chest tube insertion when the patient experiences unexpected complications is appropriate for modifier 59.

One interesting paragraph in the article describes a common misuse of modifier 59 relating to the portion of the definition describing “a different procedure or surgery.” According to the article, providers should not use modifier 59 to by-pass a CCI edit based on the two codes being “different procedures” unless the two procedures are performed at separate anatomic sites or at separate patient encounters on the same date of service. Please refer to the exact wording in the article for a clear understanding of this instruction.

Getting the correct modifiers on the correct code is not as easy as it sounds. In the hospital setting, this often involves billers, coders, and the relevant hospital departments. It also includes a financial and compliance aspect. Hospitals need a well-planned approach in dealing with CCI edits and their impact on billing and reimbursement.

Our next chapter to address in the I-10 Corner is the Digestive System. Please review the table below so that you can see what areas of the chapter have either been expanded or restructured.

EXAMPLE

UPDATE

For updated information on this topic, please click here for the more recent article: Coding Guidelines for Respiratory Failure

Whether it’s ICD-9-CM or ICD-10-CM, the coding guidelines are actually the same for Respiratory Failure. The only difference is the code itself. It’s not only important for a coder to be familiar with these guidelines but also some of the basic clinical indicators as well.

DEFINITION

from Section II of the Official ICD-9-CM Guidelines for Coding and Reporting

“Principal Diagnosis”A condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care - defined by the Uniform Hospital Discharge Data Set (UHDDS).

NOTE FROM AUTHOR
Each admission is different. The Principal Diagnosis will not be the same in every situation. Selection of the Principal Diagnosis is dependent on the circumstances of the admission. Coders should ensure that the record contains documentation that indicates clinical credibility to support the presence of that condition. It is also important for coders to understand the clinical indicators of Acute and/or Chronic Respiratory Failure in order to establish a query when necessary.

Respiratory Failure

1. Life-threatening condition that may be caused by a respiratory condition as well as a non-respiratory condition.
2. Look for documented signs / symptoms of:
3. SOB (shortness of breath)
4. Delirium and/or anxiety
5. Syncope
6. Use of accessory muscles
7. Tachycardia
8. Tachypnea
9. Confusion
10. Sleepiness
11. Depressed consciousness
12. Cyanosis (bluish color to skin, lip and/or fingernails)
13. Acute Respiratory Failure is supported as principal diagnosis when at least 2 of the following critical values (ABG’s) are met.
14. pH < 7.35
15. PO2 < 55
16. PCO2 > 50
17. Keep in mind, this is a guideline and not solely to be the determining factor for   diagnosing Acute Respiratory Failure. A patient with a chronic lung disease such as COPD may have an abnormal ABG level that could actually be considered that particular patient’s baseline. What is normal for one patient could be abnormal for another. In a patient with a chronic lung condition, the physician would consider the degree of change from a patient’s baseline before diagnosing Acute Respiratory Failure.
18. Acute Respiratory Failure
19. Develops quickly
20. Usually admitted to ICU
21. Requires aggressive and/or emergency treatment via oxygen through nasal cannula, face mask, ventilation and/or tracheostomy
22. Absence of vent does not preclude diagnosis
23. Requires close monitoring and evaluation
24. Chronic Respiratory Failure
25. Develops slowly
26. Last longer
27. Home O2 is one indication of CRF

Four classifications types for ARF

• Hypoxic – most common
• Hypercapnia – often accompanied by hypoxemia
• Post-operative
• Shock – Septic, Cardiogenic or Hypovolemic

Acute Respiratory Failure as Principal Diagnosis

OFFICIAL CODING GUIDELINE

ICD-10-CM – Section I.C.10.b.1

(ICD-9-CM – Section I.C.8.c.1)

Acute or Acute on Chronic Respiratory Failure may be assigned as a principal diagnosis when it is the condition established after study to be chiefly responsible for occasioning the admission to the hospital, and the selectionis supported by the Alphabetic Index and Tabular List. However, chapter-specific coding guidelines (such as obstetrics, poisoning, HIV, newborn) that provide sequencing direction take precedence.

OFFICIAL CODING GUIDELINE

ICD-10-CM – Section I.C.10.b.3

(ICD-9-CM – Section I.C.8.b.3)

When a patient is admitted with Respiratory Failure and another acute condition (e.g., Myocardial Infarction, Cerebrovascular Accident, Aspiration Pneumonia), the principal diagnosis will not be the same in every situation. This applies whether the other acute condition is a respiratory or non-respiratory condition. Selection of the principal diagnosis will be dependent on the circumstances of admission.   If both the Respiratory Failure and the other acute condition are equally responsible for occasioning the admission to the hospital, and there are no chapter-specific sequencing rules, the guideline regarding two or more diagnoses that equally meet the definition for principal diagnosis (Section II.C) may be applied in these situations.

If the documentation is not clear as to whether Acute Respiratory Failure and another condition are equally responsible for occasioning the admission, query the provider for clarification.

When coding Respiratory Failure (or any condition) and trying to determine whether it should be assigned as principal diagnosis or not, look for:

1. All signs and symptoms at the time of admission
2. Clinical indicators
3. Supporting physician documentation
4. Treatment plans

With any record, keep in mind that because a condition may be present on admission does not necessarily mean if qualifies for principal diagnosis. You have to ask yourself these questions:

• After study, is this the condition that was chiefly responsible for admission?
• How aggressive was the work-up and treatment?
• Is there another condition that equally meets the criteria for principal diagnosis?
• Are there any chapter specific guidelines to consider?
• Could this condition have been treated as an outpatient?

I wish I could say that assigning the appropriate principal diagnosis and coding in general was as easy as ABC, but it’s not. Some are a little easier than others but there seems to always be a little gray area to muddle through. Clear and precise documentation goes a long way in helping to determine the principal diagnosis.

As you take on a record to code, forget about the one you just finished. Each record and the circumstances surrounding the admission will be different.   Always be aware of the coding guidelines and follow through the steps listed above. You’ll find that assigning the principal diagnosis will be a little easier.

This week the focus is on Chapter 12 – Diseases of Skin and Subcutaneous Tissue.   Like many chapters in ICD-10-CM, Chapter 12 has also been restructured.   Diseases that are related in one way or another have been grouped together. In ICD-10-CM, Chapter 12 has 9 subchapters:

• L00 – L08  Infections of the skin and subcutaneous tissue
• L10 – L14  Bullous disorders
• L20 – L30  Dermatitis and eczema
• L40 – L45  Papulosquamous disorders
• L49 – L54  Urticaria and erythema
• L55 – L59  Radiation-related disorders of the skin and subcutaneous tissue
• L60 – L75  Disorders of skin appendages
• L76  Intraoperative and post-procedural complications of skin and subcutaneous tissue
• L80 – L99  Other disorders of the skin and subcutaneous tissue

There is greater specificity for many of the codes at the fourth, fifth and sixth character. Examples for Decubitus (Pressure) Ulcers would be:

• Specified site (elbow, hip, sacral, ankle, back, buttock, heel, other site, unspecified site and contiguous site of back, buttock and hip)
• Laterality (right, left)
• Severity (stage)
• Classified Stage 1 through Stage 4
• Unspecified Stage
• Unstageable

Under ICD-9-CM 2 codes were required for Decubitus (Pressure) Ulcers. One code in ICD-10-CM provides:

• Ulcer site
• Laterality
• Stage
• Additional code should be assigned and sequenced first for any associated Gangrene.

CODING GUIDELINE

I.C.12.1

Pressure Ulcer Stages: Codes from category L89, Pressure Ulcer, are combination codes that identify the site of the Pressure Ulcer as well as the stage of the Ulcer. ICD-10-CM classifies Pressure Ulcer Stages based on severity, which is designated by Stages 1-4, Unspecified Stage, and Unstageable. Assign as many codes from category L89 as needed to identify all the Pressure Ulcers the patient has, if applicable.

Different stages for Pressure Ulcers:

• Stage 1 – Wounds that only involve the upper epidermis. Pre-ulcer skin changes limited to persistent focal edema
• Stage 2 – A wound progressing toward the dermis. An abrasion, blister and partial skin loss involving epidermis and/or dermis.
• Stage 3 – A wound involving the subcutaneous tissue. Full skin loss involving damage or necrosis of subcutaneous tissue
• Stage 4 – A wound that goes down into the deeper tissue. Necrosis of soft tissue through to underlying muscle, tendon, or bone.

Coding Guidelines for healed or healing Pressure Ulcer

• Section I.C.12.a.4 – Pressure Ulcer documented as healed – no code would be assigned.
• Section I.C.12.a.5 – Pressure Ulcer documented as healing – assign appropriate Pressure Ulcer Stage code based on the documentation in the medical record. If the documentation does not provide information about the stage of the healing Ulcer, assign the appropriate code for Unspecified Stage.Codes for Non-pressure Ulcers of the lower extremity also include site, laterality and severity (depth of the Ulcer). Examples of depth description for Chronic Ulcer of Right Ankle:
• Limited to breakdown of skin – L97.311
• With fat layer exposed – L97.312
• With necrosis of muscle – L97.313
• With necrosis of bone – L97.314
With unspecified severity – L97.319

Code first any associated underlying condition:

• Atherosclerosis
• Gangrene
• Diabetic Ulcers
• Varicose Ulcer
• Chronic Venous Hypertension
• Post-phlebitic Syndrome
• Post-thrombotic Syndrome

CODING GUIDELINE

I.B.14

Documentation for BMI and Pressure Ulcer Stages: For the body mass index (BMI) and Pressure Ulcer Stage codes, code assignment may be based on medical record documentation from clinicians who are not the patient’s provider (i.e. physician or other qualified practitioner legally accountable for establishing the patient’s diagnosis), since this information is typically documented by other clinicians involved in the care of the patient (e.g., a dietician often documents the BMI and nurses often document the Pressure Ulcer Stages). However, the associated diagnosis (such as overweight, obesity, or pressure ulcer) must be documented by the patient’s provider. If there is conflicting medical record documentation, either from the same clinician or different clinicians, the patient’s attending provider should be queried for clarification.

In ICD-10-CM, terms “Dermatitis” and “Eczema” are used synonymously and interchangeably.

CODING NOTE

An instructional note appears in the Tabular, under codes L27.0 and L27.1, stating to use an additional code for Adverse Effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

CODING GUIDELINE

I.C.19.e

Adverse Effects, Poisoning, Under-dosing and Toxic Effects: Codes in categories T36-T65 are combination codes that include the substance that was taken as well as the intent.

No additional external cause code is required for poisonings, toxic effects, adverse effects and under-dosing codes.

CODING GUIDELINE

I.C.19.e.5.a

Adverse Effect: When coding an Adverse Effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the Adverse Effect of the drug (T36-T50). The code for the drug should have a fifth or sixth character of 5.

Radiation-related disorders of the skin and subcutaneous tissue now have their own subchapter. Previously in ICD-9-CM, Sunburns were listed in the Injury and Poisoning Chapter.

DEBRIDEMENT

Anyone that has coded for any length of time knows the difference between Excisional and Non-excisional Debridement. This procedure has been under scrutiny by Medicare’s Recovery Auditors (RA previously known as RAC) due to the vast difference in DRG payment.   One of the biggest problems is getting required documentation necessary to code Excisional Debridement. I hate to say, but ICD-10-PCS is not going to make it any easier.

Unlike ICD-9-CM, ICD-10-PCS codes according to root operations. Depending on the method used, a Debridement procedure could actually fit into two different root operations.

• Excision – Cutting out or off, without replacement, a portion of a body part.
• Excisional Debridement would fit this category
• Extraction – Pulling or stripping out or off all or a portion of a body part by the use of force.
• Non-excisional Debridement would fit this category

It is not enough for a physician to state they did an Excisional or Non-excisional Debridement. In order to code this procedure correctly there are documentation requirements that must be met.

• Condition requiring Debridement
• Location of wound
• Depth of Debridement – code to the deepest layer
• Method of Debridement (sloughing off tissue, cutting away etc.)
• Specific tissue removed (skin, bone, muscle etc.) – cutting back to pink tissue or removal of necrotic tissue does not help with coding the procedure. It does not describe the type of tissue removed.
• Instruments used (scissors, scalpel etc.)

Sometimes coders tend to think that the type of instrument alone is indicative as to the type of Debridement that was performed. This is not always true. A scalpel and/or scissors can be used to cut or scrap the wound. The physician should accurately describe in detail each bullet listed above in his/her procedure note.

Please note, there is no default code for Debridement.   There must be precise documentation within the record and/or procedure note.   Physicians should always be queried anytime documentation provided is not clear.  

On April 1st, President Obama signed into law the Protecting Access to Medicare Act of 2014. Per a White House Press Secretary release this new law “averts cuts to Medicare physician payments that will go into effect on April 1, 2014, under the current-law “sustainable growth rate” system, to extend other health-related provisions set to expire, and to make other changes to current-law health provisions.” In addition to averting cuts to physician payments, this law includes additional “Medicare Extenders” and “Other Health Provisions.” But before looking at some of the more significant topics within the law, it is interesting to note how quickly this bill was presented, voted on and became law.

• March 26, 2014: Representative Joe Pitts (R-PA), Chairman, Energy and Commerce Subcommittee on Health introduced H.R. 4302 the Protecting Access to Medicare Act of 2014.
• March 27, 2014: The House voted by a voice vote and approved the bill. This vote was under special rules that provided for no amendments, limited debate and only needed a two-thirds majority votes.
• March 31, 2014: The United States Senate passed the bill with a vote of 64 YEAs, 35 NAYs and 1 Not Voting.

April 1, 2014: The Act was signed into law by President Obama signed the Protecting Access to Medicare Act of 2014 into Law.

Spotlight on Extensions and Health Provisions in the Law:

Section 101: Physician Payment Update: This section provides for a 0.5 percent update for claims with dates of service on or after January 1, 2014, through December 31, 2013. Further, it provides a zero percent update to the 2015 Medicare Physician Fee Schedule (MPFS) through March 31, 2015.

Section 103: Extension of Therapy Cap Exception Process: This section extends the exceptions process for outpatient therapy caps through March 31, 2015. When a provider requests an exception to the cap for medically necessary services they must submit the KX modifier on their claim. This law extends the application of the caps, exceptions process, and threshold for therapy services provided in a hospital outpatient department (ODP).

Therapy caps for 2014:

• Occupational Therapy (OT) cap is $1,920
• Physical Therapy (PT) and Speech-Language Pathology Services (SLP) combined is $1,920

Additional information regarding therapy caps can be found on the CMS Therapy Cap webpage as well as Chapter 5, Section 10.3 in the Medicare Claims Processing Manual.

Section 106: Extension of the Medicare-Dependent Hospital (MDH) Program: This program provides enhanced payment to small rural hospitals where Medicare beneficiaries makes up a significant percentage of inpatient days or discharges. This provision extends the program through March 31, 2015.

More information about MDH Hospitals can be found in the Acute Care Hospital Inpatient Prospective Payment System Fact Sheet. Specific criteria to be designated a MDH Hospital includes:

• It is rural (located in a rural area);
• It has 100 or fewer beds during the cost reporting period;
• It is not also classified as a Sole Community Hospital (SCH); and
• At least 60 percent of its inpatient days or discharges were attributable to Medicare Beneficiaries entitled to Part A during the hospital’s cost reporting period.

Section 111: Extension of Two-Midnight Rule:

For hospital staff closely involved in trying to implement the Two-Midnight Rule, I felt it was important to provide you with the exact language in the bill.

“(a) CONTINUATION OF CERTAIN MEDICAL REVIEW ACTIVITIES.— The Secretary of Health and Human Services may continue medical review activities described in the notice entitled ‘‘Selecting Hospital

Claims for Patient Status Reviews: Admissions On or After October 1, 2013’’, posted on the Internet website of the Centers for Medicare & Medicaid Services, through the first 6 months of fiscal year

2015 for such additional hospital claims as the Secretary determines appropriate. (b) LIMITATION.—The Secretary of Health and Human Services shall not conduct patient status reviews (as described in such notice) on a post-payment review basis through recovery audit contractors under section 1893(h) of the Social Security Act (42 U.S.C. 1395ddd(h)) for inpatient claims with dates of admission October 1, 2013, through March 31, 2015, unless there is evidence of systematic gaming, fraud, abuse, or delays in the provision of care by a provider of services (as defined in section 1861(u) of such Act (42 U.S.C. 1395x(u))).”

What does this mean for hospitals?

• The Medicare Administrative Contractor (MAC) Probe and Educate program has now been extended for a fourth time through March 31, 2015.
• Recovery Audit Contractors “shall not conduct patient status reviews on a post-payment review basis” for inpatient claims with dates of service October 1, 2013 through March 31, 2015. It is important to remember that on February 18th CMS announced that current RAC activity is winding down during the new contract procurement round.
• Hospitals should take advantage of this additional time to continue to educate staff and fine tune your processes.

Section 212: Delay in Transition for ICD-9 to ICD-10 Code Sets

“The Secretary of Health and Human Services may not, prior to October 1, 2015, adopt ICD–10 code sets as the standard for code sets under section 1173(c) of the Social Security Act (42 U.S.C. 1320d–2(c)) and section 162.1002 of title 45, Code of Federal Regulations.”

This is a significant delay for everyone that has been proactively planning and providing education for an October 1, 2014 transition to the ICD-10 Code Sets. MMP plans to continue to provide I-10 Corner articles and encourages all to not look at this as a setback but as an opportunity to provide more training to your staff and test the readiness of your computer systems.

Section 221: Medicaid DSH

This law delays reductions in payments to Disproportionate Share Hospitals (DSH) by a year and then makes additional reductions through 2024.

There are still quite a few extensions and provisions not discussed in this article. MMP encourages those interested to review the Protecting Access to Medicare Act of 2014 in its entirety.

For this edition of the I-10 Corner, we have included some helpful hints that will make coding procedures in the Endocrine System a little easier.   To gain familiarity, practice looking up procedures in the ICD-10-PCS coding book that are performed at your facility on a routine basis.

Knowing the Root Operations is the key to making all of this work!                                              

FROM THE ICD-10-PCS REFERENCE MANUAL

Examples of Root Operations

Excision—Root operation B

Definition: Cutting out or off, without replacement, a portion of a body part

Explanation: The qualifier Diagnostic is used to identify excision procedures that are biopsies

Examples: Partial thyroidectomy, ovarian biopsy

Excision is coded when a portion of a body part is cut out or off using a sharp instrument. All root operations that employ cutting to accomplish the objective allow the use of any sharp instrument, including but not limited to

• Scalpel
• Wire
• Scissors
• Bone saw
• Electrocautery tip

Resection—Root operation T

Definition: Cutting out or off, without replacement, all of a body part

Explanation: N/A

Examples: Total nephrectomy, total lobectomy of lung

Resection is similar to Excision, except Resection includes all of a body part, or any subdivision of a body part that has its own body part value in ICD-10-PCS, while Excision includes only a portion of a body part.

Release—Root operation N

Definition: Freeing a body part from an abnormal physical constraint by cutting or by use of force

Explanation: Some of the restraining tissue may be taken out but none of the body part is taken out

Examples: Adhesiolysis of right ovary

The objective of procedures represented in the root operation Release is to free a body part from abnormal constraint. Release procedures are coded to the body part being freed. The procedure can be performed on the area around a body part, on the attachments to a body part, or between subdivisions of a body part that are causing the abnormal constraint.

Reposition—Root operation S

Definition: Moving to its normal location or other suitable location all or a portion of a body part

Explanation: The body part is moved to a new location from an abnormal location, or from a normal location where it is not functioning correctly. The body part may or may not be cut out or off to be moved to the new location

Examples: Reposition of undescended testicle

Reposition represents procedures for moving a body part to a new location. The range of Reposition procedures includes moving a body part to its normal location, or moving a body part to a new location to enhance its ability to function.

Laterality is necessary in code assignment for the following organs:

• Thyroid
• Ovaries
• Testicles
• Adrenals

EXAMPLE

‍

Don’t Forget: 0 vs O:

FROM THE ICD-10-PCS REFERENCE MANUAL

Values

One of 34 possible values can be assigned to each character in a code: the numbers 0 through 9 and the [whole] alphabet (except I and O, because they are easily confused with the numbers 1 and 0).

FROM THE ICD-10-CM OFFICIAL GUIDELINES FOR CODING AND REPORTING 2014
B4. Body Part

B4.3 Bilateral body part values are available for a limited number of body parts. If the identical procedure is performed on contralateral body parts, and a bilateral body part value exists for that body part, a single procedure is coded using the bilateral body part value. If no bilateral body part value exists, each procedure is coded separately using the appropriate body part value.

This edition addresses some of the changes found in the Endocrine System. Please refer to your ICD-10-CM code book to gain familiarity with the codes as this chapter has significantly expanded. Then try to notice what documentation is missing from the records you are reviewing so that you can advise your physicians on what is needed for I-10. Once again, brushing up on your Anatomy and Physiology will also be crucial for this chapter.

The Endocrine System consists of glands of the body that secrete hormones into the blood stream. The word Hormone means to set in motion. Hormones start the process of change in:

• Cells of specific body tissues
• A single organ
• A group of organs
• All cells of the body

Did you know? There are other organs in the body that produce hormones but, that is not their main function, such as the heart and stomach.

What Changed in the Endocrine Chapter?

• The diseases of the endocrine, nutritional, and metabolic diseases moved from Chapter 3 in I-9 to Chapter 4 in I-10
• Certain disorders of the immune system have been moved out of the endocrine chapter and into Chapter 3 in I-10, "Diseases of the Blood, Blood Forming Organs, and Certain Disorders".
• Gout was moved out of the Endocrine chapter and placed in Chapter 13, "Diseases of the Musculoskeletal System and Connective Tissue".
• The type and cause of Cushing's Syndrome is now needed to assign the correct code.
• More information is required to assign the correct code.
• For example: Congenital Hypothyroidism- The code has been expanded and we now must know if there is documentation of a goiter in order to assign the appropriate code.
• Diabetes Mellitus
• Many code titles were revised

Notice below how the two code sets differ. Chapter 4 has more than doubled in size!

DEFINITON

It will be Easy to remember that the Endocrine chapter codes begin with the letter E!

Diabetes Mellitus
One of the major changes we see in I-10 is in the Endocrine System for Diabetes Mellitus. First of all, Diabetes has its own subchapter heading. And, in I-9, Diabetes was classified to one category, 250. Now there are 5 categories for Diabetes in I-10 and they are listed below:

• E08, Diabetes Mellitus due to underlying condition
• E09, Drug or chemical induces Diabetes Mellitus
• E10, Type 1 Diabetes Mellitus
• E11, Type 2 Diabetes Mellitus
• E13, Other specified Diabetes Mellitus

Please note: "Use additional code to identify any insulin use (Z79.4)" is to be used with all diabetic cases except for Type 1. This additional insulin code is not assigned for Type 1 diabetic cases because insulin is required to maintain life.

The diabetic codes were expanded to reveal manifestations and complications of the disease via 4th or 5th characters instead of using an additional code to identify the manifestation.

FROM THE MANUAL

Here is an example of how the diabetic codes have been expanded to include more information as compared to I-10:

‍NOTE FROM AUTHOR
Trying to code controlled and uncontrolled diabetes is no longer a coding issue! Even better, we can capture inadequately controlled, out of control, and poorly controlled diabetes and code it to Diabetes Mellitus, by type with hyperglycemia.

DEFINITON

‍Hemoglobin A1c: 7 is not a lucky number when it comes to Diabetes!

A1C is a blood test that will determine an average blood sugar reading over a period of 3 months and will reveal how well diabetes is being controlled. An A1c level of <7% is the goal for all diabetics. The higher the A1c level, the higher the risk of developing diabetic complications. The table shows an A1c with the corresponding estimated average glucose reading (eAG).

FYI - Secondary Diabetes Mellitus
This type of diabetes is caused by another disease or condition. The code title has changed in I-10 for Secondary Diabetes:

I-9 Secondary diabetes mellitus, 249.0
vs.
I-10 Diabetes due to underlying condition, E08

NOTE FROM AUTHOR
Pay attention to the code instructions under E08 when coding Secondary Diabetes:
Code first the underlying condition, such as:

• Congenital Rubella (P35.0)
• Cushing's Syndrome (E24.-)
• Cystic Fibrosis (E84.-)
• Malignant Neoplasm (C00-C96)
• Malnutrition (E40-E46)
• Pancreatitis and other diseases of the pancreas (K85.-, K86.-)

Use additional code to identify any insulin use (Z79.4)

Coding Guidelines for Diabetes Mellitus

FROM THE ICD-10-CM OFFICIAL GUIDELINES FOR CODING AND REPORTING 2014

Coding Guideline I.C.4.a., Diabetes Mellitus
The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting the body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08-E13 as needed to identify all of the associated conditions that the patient has.

Coding Guideline I.C.4.a.5 (a), Underdose of insulin due to insulin pump failure
An underdose of insulin due to an insulin pump failure should be assigned to a code from subcategory T85.6, Mechanical complication of other specified internal and external prosthetic devices, implants and grafts, that specifies the type of pump malfunction, as the principal or first-listed code, followed by code T38.3x6-, Underdosing of insulin and oral hypoglycemic [antidiabetic] drugs. Additional codes for the type of diabetes mellitus and any associated complications due to the underdosing should also be assigned.

Coding Guideline I.C.4.a.6., Secondary Diabetes Mellitus
Codes under categories E08, Diabetes mellitus due to underlying condition, and E09, Drug or chemical induced diabetes mellitus, identify complications/manifestations associated with secondary diabetes mellitus. Secondary diabetes is always caused by another condition or event (e.g., cystic fibrosis, malignant neoplasm of pancreas, pancreatectomy, adverse effect of drug, poisoning).

Coding Guideline I.C.4.a.6.b., Assigning and Sequencing Secondary Diabetes Codes and Its Causes
The sequencing of the secondary diabetes codes in relationship to codes for the cause of the diabetes is based on the Tabular List instructions for categories E08 and E09.

There are expanded instructions in Chapter 4 for coding late effects now called "Sequelae" in I-10.

EXAMPLE FROM ICD-10-CM CODER TRAINING MANUAL
Excludes 1 notes have been added to some categories between E50-E63 to indicate that the sequelae of the nutritional deficiency are assigned a code from category E64.
