CMS published Change Request (CR) 12471 in October 2021 to:

• Implement system changes needed to update the Shared System Maintainer (SSM) interface with the Java MCE to accept new MCE Edit 20-Unspecific Code Edit, and
• Provide a mechanism to systematically bypass the new edit when a specific billing note is present in the claim remarks field to indicate the primary reason laterality could not be determined.

This new edit became effective for hospital inpatient discharges occurring on or after April 1, 2022.

 

Why this Matters?

In ICD-10-CM there are unspecified codes for when documentation in the record does not provide detail needed to report a more specific code. “However, in the inpatient setting, there should generally be very limited and rare circumstances for which the laterality (right, left, bilateral) of a condition is unable to be documented and reported.”

 

Code Edit 20- is triggered when an unspecified diagnosis code currently designated as either a Complication or Comorbidity (CC) or Major Complication or Comorbidity (MCC), that includes other codes in that code subcategory that further specify the anatomic site, is entered.

 

This edit is meant to signal providers that there is a more specific laterality code available to report. It will be the provider’s responsibility to determine if documentation in the medical record supports a more specific code. “If, upon review, additional information to identify the laterality from the available medical record documentation by any other clinical provider is unable to be obtained or there is documentation in the record that the physician is clinically unable to determine the laterality because of the nature of the disease/condition, then the provider must enter that information in the remarks section.”

 

Mechanism to Bypass new MCE Edit 20-

Enter one of the following in the Remarks Field to enable your MAC to systematically bypass the edit and process your claim:

• UNABLE TO DET LAT 1 to show you are unable to obtain additional information to specify laterality, or
• UNABLE TO DET LAT 2 to show the physician is clinically unable to determine laterality.

   

  “If there is no language entered into the remarks section as to the availability of additional information to specific laterality and the provider submits the claim for processing, the claim would be returned to the provider.”

   

  Table 6P.3a associated with the FY 2022 IPPS/LTCH Final Rule contains the initial list of 3,432 ICD-10-CM unspecified codes.

   

  In the FY 2024 IPPS Proposed Rule, CMS has proposed the addition of new ICD-10-CM diagnosis codes that will be effective October 1, 2023 to the list of codes subject to Code Edit 20-.  Specifically, CMS has proposed adding:

• Twelve new ICD-10-CMS age related and other osteoporosis codes with current pathological fracture diagnosis codes (M80.0B9A, M80.0B9D, M80.0B9G, M80.0B9K, M80.0B9P, M80.0B9S, M80.8B9A, M80.8B9D, M80.8B9G, M80.8B9K, M80.8B9P, and M80.8B9S), and
• Four unspecified pressure ulcer codes that CMS identified as being inadvertently omitted from this list effective with discharges on or after April 1, 2022 (L89.103, L89.104, L89.93, and L89.94).

 

Why It Matters by the Numbers?

RealTime Medicare Data (RTMD), our sister company, maintains a database of Medicare Fee-for-Service paid claims data for all states and Washington, D.C. While I am unable to identify how many claims were returned to the provider, based on claims data, it appears that hospitals have significantly decreased the volume of claims that includes one of the 3,432 unspecified codes.

 

Six months Prior to implementation of Code Edit 20- (October 1, 2021 – March 2022 Data)

• 26,892: The volume of claims including one of the 3,432 unspecified codes,
• $485,063,597: The total payment for this group of claims.

   

  Six months Post April 1, 2022 Implementation of Code Edit 20- (April 1 – September 30, 2022)

• 2,244: The volume of claims including one of the 3,432 unspecified codes,
• $32,653,438: The total payment for this group of claims.

 

What Can I Do?

Share this information with key stakeholders at your facility (i.e., billing, coding, clinical documentation integrity specialists and watch for the release of the FY 2024 final rule later in the year to confirm that CMS finalized this proposal.

Did You Know?

Livanta, the National Medicare Claim Review Contractor, is actively reviewing two types of reviews monthly.  

Higher weighted diagnosis-related groups (HWDRG) Reviews: When a hospital resubmits a claim with a higher weighted DRG as a correction to the original claim, this “is a trigger for a potential review of an inpatient claim. This review activity helps ensure that the patient’s diagnostic, procedural, and discharge information is coded and reported properly on the hospital’s claim and matches documentation in the medical record.”  

Short Stay Reviews (SSRs): For SSRs, “reviewers at Livanta obtain and evaluate the medical record to ensure that the patient’s admission and discharge were medically appropriate based on the documentation of the patient’s condition and treatment rendered during the stay, and that the corresponding Part A Medicare claim submitted by the provider was appropriate.” 

Why It Matters? 

HWDRG Reviews: When a hospital’s HWDRG claim is subject to a post-payment review, in addition to DRG validation of the adjusted claim, the review will include validation of medical necessity of the inpatient admission. 

SSRs: Short Stays are a high volume and high-cost review focus for more contractors than Livanta. RealTime Medicare Data’s (RTMDs) database includes Medicare Fee-for-Service paid claims for the nation. The following RTMD data represents paid short stay claims in CY 2022:

• 874,104: The volume of short stay claims,
• $47,043,865,852: The total charges by hospitals for short stay claims, and
• $10,052,743,324: The total payment by Medicare to hospital for short stays.

Discharge disposition codes expired (20), transfer to another acute care facility (02), transfer to a short-term general hospital with a planned acute care hospital inpatient admission (82), left against medical advice (07), and hospice election (50 & 51) are excluded from the short stay RTMD data as CMS considers them to be unforeseen circumstances. 

Office of Inspector General (OIG)

Prior OIG audits identified millions of dollars in overpayments for inpatient claims with short lengths of stay. The OIG had previously stated they would not audit short stays after October 1, 2013; however, their current work plan includes a review of CMS’ Oversight of the Two-Midnight Rule for Inpatient Admissions.

Comprehensive Error Rate Testing (CERT)

Since the October 1, 2013 implementation of the Two-Midnight Rule, as part of their annual report, the CERT review contractor has reported hospital inpatient review findings by length of stay. The improper payment rate for “0 or 1 day” claims is consistently higher than other lengths of stay. In fact, the improper payment rate for short stay claims increased from 16.8% in 2021 to 20.1% in 2022 with a projected improper payment of $1.5B.

Program for Evaluating Payment Patterns Electronic Report (PEPPER)

One-Day stays for medical and surgical DRGs are review targets in the short-term acute care PEPPER. The suggested intervention for high outliers is that “this could indicate that there are unnecessary admissions related to the inappropriate use of admission screening criteria or outpatient observation. A sample of one-day stay cases should be reviewed to determine whether inpatient admission was necessary or if care could have been provided more efficiently on an outpatient basis (e.g., outpatient observation).”

What Can I Do?

Livanta provides several education resources on their website. For example, the Livanta Claims Review Advisor newsletter alternates between SSRs and HWDRG reviews. Examples of newsletter topics includes: 

HWDRG Review Topics: Physician Queries, Sepsis DRGs, Encephalopathy, Anemia and GI Bleeding, and Malnutrition, and Short Stay Review Topics: Chest Pain, Atrial Fibrillation, Congestive Heart Failure, and Transient Ischemic Attack Case Scenarios.

I encourage you to share this information with your HIM, Case Management, and Clinical Documentation Integrity staff.

36^th Edition of Short-Term Acute Care Hospitals Users Guide at https://pepper.cbrpepper.org/

 

CMS issued a display copy of the FY 2024 IPPS Proposed Rule on Monday, April 10, 2023. This article contains a high-level look at the proposed operating payment rate changes, Rural Emergency Hospitals change, social determinants of health codes severity designation changes, when the New COVID-19 Treatment Add-On Payments are proposed to end, and updates to the Affordable Care Act Quality Programs.

Proposed Payment Rate Changes

The proposed increase in operating payment rates for general acute care hospitals paid under the IPPS that successfully participate in the Hospital Inpatient Quality Reporting (IQR) Program and meaningful electronic health record (EHR) use is projected to be 2.8%.

In a summary of costs and benefits in the proposed rule, CMS notes that “acute care hospitals are estimated to experience an increase of approximately $2.7 billion in FY 2024, primarily driven by: (1) a combined $3.2 billion increase in FY 2024 operating payments and capital payments, as well as changes in DSH and uncompensated care payments, and (2) a decrease in $466 million resulting from estimated changes in new technology add-on payments, as modeled for this proposed rule.”

Rural Emergency Hospitals (REHs) and Graduate Medical Education (GME)

REH’s became a new provider type effective January 1, 2023. You can read more about them in a related MLN Fact Sheet. CMS is proposing to change to GME payments for training in a REH “to address the growing concern over closures of rural hospitals.”

Social Determinants of Health

The U.S. Department of Health and Human Services (HHS) defines Social Determinants of Health (SDOH) as "the conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks." Effective February 18, 2018, the AHA Coding Clinic published advice allowing the reporting of SDOH codes Z55-Z65, based on information documented by all clinicians involved in the care of the patient.

For FY 2024, CMS is proposing to change the severity level designation for diagnosis codes Z59.00 (Homelessness, unspecified), Z59.01 (Sheltered homelessness), and Z59.02 (Unsheltered homelessness) from NonCC to CC for FY 2024. CMS also continues to be interested in receiving feedback on “how we might otherwise foster the documentation and reporting of the diagnosis codes describing social and economic circumstances to more accurately reflect each health care encounter and improve the reliability and validity of the coded data including in support of efforts to advance health equity.”

Changes to the New COVID-19 Treatment Add-On Payment (NCTAP)

In response to the Public Health Emergency (PHE), CMS established NCTAP for eligible discharges during the PHE. In the FY 2022 final rule, CMS finalized the extension of NCTAP through the end of the FY in which the PHE ends. In the FY 2024 proposed rule, CMS notes “if the PHE ends in May of 2023, as planned by the Department of Health and Human Services (HHS), discharges involving eligible products would continue to be eligible for the NCTAP through September 30, 2023 (that is, through the end of FY 2023).”

Affordable Care Act Quality Programs

Hospital Readmission Reduction Program (HRRP)

CMS is not proposing any changes to this value-based purchasing program that reduces payments to hospitals with excess readmissions.

Hospital-Acquired Condition (HAC) Reduction Program

This program creates an incentive for hospitals to reduce the incidence of hospital-acquired conditions by reducing payment by 1% for applicable hospitals ranking in the worst-performing quartile on select measures. For FY 2023, due to the ongoing COVID-19 PHE, no hospital was subject to the 1-percent payment reduction. You can read more about this program in a related FY 2023 CMS Fact Sheet.

In the FY 2024 proposed rule, CMS is requesting comments from stakeholders on potential future measures that would advance patient safety and reduce health disparities.

Hospital Value-Based Purchasing (VBP) Program

This is a budget-neutral program funded by reducing hospitals’ base operating DRG payments each fiscal year by 2% and redistributing the entire amount back to the hospitals as value-based incentive payments. Like the HAC Reduction Program, CMS finalized hospitals’ keeping the 2% payment due to the ongoing COVID-19 PHE. For FY 2024, CMS is proposing several changes to this program, for example:

• Adopting the Severe Sepsis and Septic Shock: Management Bundle measure in the Safety Domain beginning with the FY 2026 program year, and
• Adopting changes to the administration and submission requirements of the HCAHPS survey measure beginning with the FY 2027 program year.

CMS is also requesting feedback on potential additional future changes to the Hospital VBP Program scoring methodology that would address health equity.

I encourage you to submit comments to CMS. The deadline to submit comments is June 9, 2023.

CMS FY 2024 Proposed Rule Home Page: https://www.cms.gov/medicare/acute-inpatient-pps/fy-2024-ipps-proposed-rule-home-page

The FY 2024 IPPS Proposed Rule (CMS-1785-P) was issued by CMS April 10, 2023. This article focuses on proposed changes to Medicare Severity Diagnosis-Related Group (MS-DRG) classifications in Major Diagnostic Categories (MDCs) 02, 04, and 06 (Diseases and Disorders of the Eye, Respiratory System, and Digestive System, respectively).

MDC 02: Diseases and Disorders of the Eye: Retinal Artery Occlusion

A request was made to review the MS-DRG assignment of cases involving central retinal artery occlusion (CRAO). The assertion was that CRAO is a form of acute ischemic stroke which occurs when a vessel supplying blood to the brain is obstructed and there is growing recognition of this diagnosis as a vascular neurological problem. New evidence outlines treatment of patients with CRAO with acute stroke protocols, specifically with intravenous thrombolysis or hyperbaric oxygen therapy, to improve outcomes.

Based on this request, data analysis and examining clinical considerations, CMS is proposing to:

• Reassign ICD-10-CM diagnosis codes H34.10, H34.11, H34.12, H34.13, H34.231, H34.232, H34.233, and H34.239 from MDC 02 MS-DRG 123 to MS-DRGs 124 and 125,
• Add procedure codes describing the administration of a thrombolytic agent listed in this section of the proposed rule to MS-DRG 124,
• As part of the logic for MS-DRG 124, designate the administration of thrombolytic agent codes as non-O.R. procedures affecting the MS-DRG, and
• Change the titles of MS-DRGs 124 and 125 from “Other Disorders of the Eye, with and without MCC, respectively,” to “Other Disorders of the Eye with MCC or Thrombolytic Agent, with without MCC, respectively” to better reflect the assigned procedures.

MDC 04: Diseases and Disorders of the Respiratory System: Ultrasound Accelerated Thrombolysis for Pulmonary Embolism

A request was made to reassign cases reporting ultrasound accelerated thrombolysis (USAT) with administration of thrombolytic(s) for the treatment of pulmonary embolism (PE) from MS-DRGs 166, 167, and 168 (Other Respiratory O.R. Procedures with MCC, with CC, and without CC/MCC, respectively) to MS-DRGs 163, 164, and 165 (Major Chest Procedures with MCC, with CC, and without CC/MCC, respectively).

CMS believes clinical and data analyses support creating a new base MS-DRG for cases reporting a principal diagnosis of PE and USAT or standard catheter directed thrombolysis (CDT) procedures with or without thrombolytics and are proposing new base MS-DRG 173 (Ultrasound Accelerated and Other Thrombolysis with Principal Diagnosis of Pulmonary Embolism).

MDC 04: Respiratory Infections and Inflammations Logic

There are two logic lists for case assignment to MS-DRGs 177, 178, and 179 (Respiratory Infections and Inflammations with MCC, with CC, without CC/MCC, respectively). All diagnosis codes in the first logic list are designated as MCCs.

Currently, if the principal diagnosis is from the second logic list and any of the diagnoses from the first logic list are also on the claim, the case would be assigned to MS-DRG 177. This is inconsistent with how other similar logic lists function in the ICD-10 grouper software. Therefore, CMS is proposing to correct the logic for cases assigned to MS-DRG 177 by excluding the 15 diagnosis codes in the first logic list from acting as an MCC when reported as a secondary diagnosis when the principal diagnosis is from the second logic list.

MDC 06: Diseases and Disorders of the Digestive System: Appendicitis

ICD-10-CM diagnosis codes K35.20 (Acute appendicitis with generalized peritonitis, without abscess) and K35.21 (Acute appendicitis with generalized peritonitis, with abscess) will no longer be effective October 1, 2023. At that time, six new diagnosis codes describing acute appendicitis with generalized peritonitis, with and without perforation or abscess will become effective. The new codes are proposed for assignment to MS-DRGs 371, 372, and 373 (Major Gastrointestinal Disorders and Peritoneal Infections with MCC, with CC, and without MCC/CC, respectively).

CMS notes that clinically both localized and generalized peritonitis in association with an appendectomy require the same level of patient care and believe the distinction between “complicated” versus “uncomplicated” is no longer meaningful regarding resource consumption. Therefore, CMS is proposing to delete MS-DRGs 338, 339, 340, 341, 342, and 343 and proposing to create new MS-DRGs 397, 398, and 399 (Appendix Procedures with MCC, with CC, and without CC/MCC, respectively). The new MS-DRGs would no longer require a diagnosis in the definition of the logic for case assignment.

CMS is accepting comments through June 9, 2023.  

Resource: FY 2024 IPPS Proposed Rule Home Page

For the CMS FY 2024, CMS has proposed several changes to the Major Diagnostic Category (MDC) 05: Diseases and Disorders of the Circulatory System. This article focuses on these proposed changes. You can read about proposed changes in other MDCs in a related article in this week’s newsletter.

Surgical Ablation

A request was made for CMS to review the MS-DRG assignment of cases involving open concomitant surgical ablation procedures, recommending that open concomitant surgical ablation procedures for atrial fibrillation (AF) be reassigned from MS-DRGs 219, 220, and 221 (Cardiac Valve and Other Major Cardiothoracic Procedures without Cardiac Catheterization with MCC, with CC, and without CC/MCC, respectively) to MS-DRGs 216, 217, and 218 or create new MS-DRGs for all open mitral or aortic valve repair or replacement procedures with concomitant surgical ablation of AF.

CMS analysis found these cases require greater resources, have higher average costs and generally longer lengths of stay compared to all other cases in their assigned MS-DRG. CMS is proposing to create new base MS-DRG 212 (Concomitant Aortic and Mitral Valve Procedures) for cases reporting an aortic valve repair or replacement procedure, a mitral valve repair or replacement procedure, and another concomitant procedure in MDC 05.

External Heart Assist Device

Currently, the three ICD-10-PCS procedure codes describing the insertion of a short-term heart assist device are recognized as extensive O.R. procedures assigned to MS-DRG 215 (Other Respiratory O.R. Procedures with MCC, with CC, and without CC/MCC, respectively) in MDC-05. One of the codes is for an open approach (02HA0RZ: Insertion of short-term external heart assist system into heart, open approach). The other two codes describe a percutaneous approach.

CMS is proposing to reassign the open approach code when reported as a standalone procedure from MS-DRG 215 in MDC-05 to Pre-MDC MS-DRGs 001 and 002. Under this proposal, this code will no longer need to be reported as a part of a procedure code combination or procedure code “cluster” to satisfy the logic assigned to MS-DRGs 001 and 002.

Ultrasound Accelerated Thrombolysis for Deep Vein Thrombosis

A request was made to reassign cases reporting USAT of peripheral vascular structures procedures with the administration of thrombolytic(s) for deep venous thrombosis from MS-DRGs 252, 253, and 254 (Other Vascular Procedures with MCC, with CC, and without CC/MCC, respectively) to MS-DRGs 270, 271, and 272 (Other Major Cardiovascular Procedures with MCC, with CC, and without CC/MCC, respectively).

Although CMS found this subset of cases does not clinically align with patients undergoing surgery for acute myocardial infarction, the difference in resource consumption does warrant creating a new MS-DRG to reflect more appropriate payment for USAT and standard CDT procedures of peripheral vascular structures. CMS is proposing to create new MS-DRGs 278 and 279 (Ultrasound Accelerated and Other Thrombolysis of Peripheral Vascular Structures with MCC and without MCC, respectively).

Coronary Intravascular Lithotripsy

A request was made to review MS-DRG assignment of cases describing percutaneous intravascular lithotripsy (IVL) involving the insertion of drug eluting and non-drug eluting stents. According to the requestor, cases involving IVL are more complex as this is a therapy deployed exclusively in several calcified coronary lesions that are associated with longer procedure times and increased resources.

CMS analysis showed that cases reporting percutaneous coronary IVL, with or without a stent had higher average costs and lengths of stay. CMS is proposing to create two new MS-DRGs:

• MS-DRGs 323 and 324 (Coronary Intravascular Lithotripsy with Intraluminal Device with MCC and without MCC, respectively), and
• MS-DRGs 325 (Coronary Intravascular Lithotripsy without Intraluminal Device).

Eliminating Distinction Between Bare Metal and Drug Eluting Stent (DES)

CMS notes it appears to no longer be necessary to subdivide the MS-DRGs for percutaneous cardiovascular procedures based on the type of coronary intraluminal device inserted. Therefore, they are proposing to delete MS-DRGs 246, 247, 248, and 249, and are proposing new MS-DRG 321 (Percutaneous Cardiovascular Procedures with Intraluminal Device with MCC or 4+ Arteries/Intraluminal Devices) and MS-DRG 322 (Percutaneous Cardiovascular Procedures with Intraluminal Device without MCC).

CMS is also proposing to revise the titles for MS-DRGs 250 and 251 from “Percutaneous Cardiovascular without Coronary Artery Stent with MCC, and without MCC, respectively” to “Percutaneous Cardiovascular Procedures without Intraluminal Device with MCC, and without MCC, respectively” to better reflect the ICD-10-PCS terminology of “intraluminal devices” versus “stents” as used in the procedure code titles within the classification.

Cardiac Defibrillators and Shock

During a review of cardiogenic shock, CMS noted data analysis shows the average costs and length of stay are generally similar for cardiac defibrillator cases without regard to the presence of AMI, Heart Failure (HF), or shock. CMS is proposing to delete MS-DRGs 222, 223, 224, 225, 226, and 227, and create three new MS-DRGs:

• MS-DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC, and
• MS-DRGs 276 and 277 (Cardiac Defibrillator Implant with MCC, and without MCC, respectively).

Specific to MS-DRG 275, CMS is proposing to designate procedure codes describing cardiac catheterization as non-O.R. procedures affecting the MS-DRG.

CMS is accepting comments through June 9, 2023.

Did You Know?

New codes for mild neurocognitive disorder, also known as mild cognitive impairment (MCI) have been created.  Mild neurocognitive disorder can be defined as an impairment in a patient’s memory or thinking that is beyond what is considered to be normal age-related changes.  However, it is not severe enough to be classified as dementia.  Patients with MCI have symptoms that are subtle and do not affect a patient's daily life and activities.  They typically do not experience personality changes or functional impairments but have symptoms such as forgetfulness and word-finding difficulties.  Patients with MCI are at an increased risk of developing dementia caused by Alzheimer's or other neurological conditions.

Subcategory F06.7 Mild neurocognitive disorder due to known physiological condition

             Code first the underlying physiological condition, such as:

     Alzheimer’s disease

     Frontotemporal neurocognitive disorder

     Human immunodeficiency virus (HIV) disease

     Huntington’s disease

     Neurocognitive disorder with Lewy bodies

     Parkinson’s disease

     Systemic lupus erythematosus

     Traumatic brain injury

     Vitamin B deficiency

Excludes1:  Age-related cognitive decline

        Altered mental status

        Cerebral degeneration

        Change in mental status

        Cognitive deficits following sequelae of cerebral hemorrhage or infarction

        Dementia

        Mild cognitive impairment due to unknown or unspecified etiology

        Neurologic neglect syndrome

        Personality change, nonpsychotic

• F06.70, Mild neurocognitive disorder due to known physiological condition without behavioral disturbance
• F06.71, Mild neurocognitive disorder due to known physiological condition with behavioral disturbance

Why It Matters?

The new codes will help capture patients who have not yet developed dementia but do have mild cognitive impairment.  Capturing the presence or absence of behavioral disturbances is a significant indicator of the progression of the underlying disease.

What Can I Do?

Be mindful and watch for documentation of mild cognitive disorders or MCI with behavioral disturbances (combativeness, agitation, etc.) to appropriately capture these new codes. 

Please note:  Patient’s with MCI with behavioral disturbances (F06.71) is a complication/comorbidity (CC).

Did You Know?

The Code of Federal Regulations defines colorectal cancer screening tests as being any of the following procedures furnished to an individual for the purpose of early detection of colorectal cancer:

• Screening fecal-occult blood tests.
• Screening flexible sigmoidoscopies.
• Screening colonoscopies, including anesthesia furnished in conjunction with the service.
• Screening barium enemas.
• Other tests or procedures established by a national coverage determination, and modifications to tests under this paragraph, with such frequency and payment limits as CMS determines appropriate, in consultation with appropriate organizations.

Why It Matters?

Effective January 1, 2023: If you code outpatient colonoscopy procedures, be aware of new Medicare guidelines where a positive stool-based colorectal cancer-screening test can, in some cases, constitute a screening colonoscopy.

The excerpt below is from the Code of Federal Regulations and can be seen in section K at this link: eCFR :: 42 CFR 410.37 -- Colorectal cancer screening tests: Conditions for and limitations on coverage.

“A complete colorectal cancer screening. Effective January 1, 2023, colorectal cancer screening tests include a follow-on screening colonoscopy after a Medicare covered non-invasive stool-based colorectal cancer screening test returns a positive result.”

Also refer to Coding Clinic for HCPCS 4^th quarter 2022, page 17 for additional information.

What Can I Do?

Share this information with your outpatient coding professionals. For non-Medicare payers, it may be necessary to contact them directly for guidance.

The fourth quarter FY 2022 Short-Term Acute Care Program for Evaluating Payment Patterns Electronic Report (PEPPER) was released last week. At the same time, the 36^th Edition of the related PEPPER User’s Guide is now posted on the PEPPER Resources website.

About the PEPPER

As part of a hospital’s Compliance Program, regular chart audits should be completed to confirm guidance with Medicare coverage, coding, and billing requirements. The PEPPER is a free resource that provides a compare of a hospital to its state, MAC region, and the nation for specific Target Areas. This comparison enables a hospital to identify whether it is an outlier as compared to other short-term acute care hospitals.

In general, there are two types of Target Areas, targets related to DRG coding and admission necessity focused target areas. The “PEPPER does not identify the presence of payment errors, but it can be used as a guide for auditing and monitoring efforts. A hospital can use PEPPER to compare its claims data over time to identify areas of potential concern:

• Significant changes in billing practices
• Possible over- or under – coding, and
• Changes in lengths of stay.”

When CMS approves a Target Area it is because it has been identified as prone to improper Medicare payments. Historically, target areas have been the focus of past Office of Inspector (OIG) or Recovery Auditor audits.

35^th Edition PEPPER User’s Guide, What’s New?

Three target areas have been removed from the report including Excisional Debridement, Emergency Department Evaluation and Management Visits, and Chronic Obstructive Pulmonary Disease.

In keeping with the trend that MMP has noticed where services are moving away from the inpatient hospital setting, the existing Spinal Fusion target area has been modified to now include hospital outpatient spinal fusion claims.

The last change is to the existing Percutaneous Cardiovascular Procedures target area. This has been modified to remove reference to the following two outpatient codes in the denominator:

• Current Procedural Terminology® (CPT®) code 92942, and
• Healthcare Common Procedure Coding System (HCPCS) code C9606.

Moving Forward

Also included in the PEPPER User’s Guide are suggested interventions for when a hospital is a high or low outlier for each of the review targets.

DRG Coding Focused Target Area Example: Unrelated OR Procedure

• Suggested Interventions for High Outliers: “This could indicate that there are coding or billing errors related to over-coding of DRGs 981, 982, 987, 988, or 989. A sample of medical records for these DRGs should be reviewed to determine whether the principal diagnosis and principal procedure are correct.
• Suggested Intervention for Low Outlier: “This could indicate that the principal diagnosis is being billed with the related procedures No intervention is necessary.”

Admission Necessity Focused Target Area Example: Spinal Fusion

• Suggested Interventions for High Outlier: “This could indicate that unnecessary spinal fusion procedures may have been performed. A sample of medical records for spinal fusion cases, including both the inpatient and outpatient setting, should be reviewed to validate the medical necessity of the procedure. Medical record documentation of 1) previous non-surgical treatment, 2) physical examination clearly documenting the progression of neurological deficits, extremity strength, activity modification, and pain levels, 3) diagnostic test results and interpretation, and 4) adequate history of the presenting illness, may help substantiate the necessity of the procedure.”
• Suggested interventions for Low Outlier: “Not applicable, as this is an admission-necessity focused target area.”

Of note, more than half of the target areas in the 36^th Edition User’s Guide are admission-necessity focused. Moving forward, I encourage you to review your hospital’s latest PEPPER and take advantage of suggested interventions available in the User’s Guide, paying close attention to documentation that may help substantiate the inpatient admission.

Various studies have shown that PNBs following a TKA can deliver safe and effective pain relief. This type of pain relief can improve postoperative pain, patient satisfaction, and decrease the need for opioid use. Coding PNBs do not affect the DRG; however, reporting a procedure code for PNB will give a more accurate clinical picture of what was required to take care of that TKA patient.

Also, an ICD-9 Coding Clinic noted that coding a procedure for management of postoperative pain was permissible.

What Can I Do?

1. Review documentation from the Anesthesiologist that indicates the surgeon requested a PNB for postoperative pain management. This documentation is typically found on a Pre-Anesthesia Evaluation sheet. Types of PNB: Femoral, Obturator, Sciatic, Lumbar Plexus, and Adductor Canal Nerve.
2. Contact the business office to see if this procedure was captured in the Chargemaster.
3. Verify if there is a hospital policy for coding secondary procedures that do not affect the DRG.
4. Educate coding staff.

Did You Know?

The U.S. Preventive Services Task Force’s indicated in their May 18, 2021 Final Recommendation statement for colorectal cancer screening that:

• It is estimated that 10.5% of new colorectal cancer cases occur in persons younger than 50 years,
• Incidence of colorectal cancer (specifically adenocarcinoma) in adults aged 40 to 49 years has increased by almost 15% from 2000-2002 to 2014-2016,
• In 2016, 25.6% of eligible adults in the US had never been screened for colorectal cancer, and
• In 2018, 31.2% were not up to date with screening.

Based on these recommendations, this time last year I wrote that 45 was the new 50 for colorectal cancer screening.

Why it Matters?

Effective January 1, 2023, the recommended minimum age for certain colorectal screening tests has decreased from 50 to 45 years of age and older.

MLN Matters article MM13017, Removal of a National Coverage Determination and & Expansion of Coverage of Colorectal (CRC) Screening includes:

• A list of the specific screening tests where the minimum age has decreased from 50 to 45 years and older, and  
• An expanded definition of CRC screening tests and new billing instructions for colonoscopies under certain scenarios.

Also, National Coverage Determination (NCD 210.3) Colorectal Cancer Screening Tests has been revised to reflect the decrease in minimum age for each of the covered indications listed in this policy.

2023 Colorectal Cancer Screening Claims Being Held: Palmetto GBA, the Medicare Administrative Contractor for Jurisdictions J and M posted the following open claims issue regarding colorectal cancer screening claims:

“CMS has instructed Medicare Administrative Contractors to hold colorectal cancer screening claims with HCPCS codes G0104, G0105, G0106, G0120, G0121, G0327, G0328, 81528 and CPT® code 82270 until April 4, 2023. Claims for dates of service on or after January 1, 2023, will be held to allow the CMS system maintained to make updates to the claim processing system to accommodate 2023 colorectal cancer screening coverage changes.”

What Can You Do?

As a healthcare provider, be aware of the changes in Medicare’s colorectal screening coverage. The following changes have been made to the MLN Educational Tool Medicare Preventive Services: 

• Information has been added about reduced coinsurance (starting January 1, 2023) when a screening colorectal cancer procedure becomes diagnostic or therapeutic,
• The reduced minimum age for colorectal cancer screening tests from 50 to 45, and
• If a non-invasive stool-based test returns a positive test, colorectal cancer screening tests now include a follow-up screening colonoscopy.  

As a healthcare consumer, I encourage everyone to talk with your doctor about your risk(s) for colorectal cancer and the need for screening tests.
