Question:

There is confusion about coding an elevated troponin level. Should we use R77.8 per codebook or R79.89 per advice from Coding Clinic, Second Quarter 2019, pg. 6?

Answer:

The correct code assignment for an elevated troponin level is R77.8, Other Specified Abnormalities of Plasma Proteins. Coding Clinic, Second Quarter 2019, page 6 was superseded by the changes to the index that were effective with the discharges October 1, 2020. The ICD-10-CM Conventions and Coding Guidelines take precedence over Coding Clinic advice.

Did You Know?

The 2024 ICD-10-CM Official Guidelines for Coding and Reporting were posted to the CMS website on July 6, 2023 (https://www.cms.gov/medicare/icd-10/2024-icd-10-cm). You can also find the guidelines on the CDC ICD-10-CM webpage (https://www.cdc.gov/nchs/icd/Comprehensive-Listing-of-ICD-10-CM-Files.htm).

Why It Matters?

“These guidelines have been developed to assist both the healthcare provider and the coder in identifying those diagnoses that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved. The entire record should be reviewed to determine the specific reason for the encounter and the conditions treated.” As of July 19^th, there are only 73 days to become familiar with the October 1, 2023, changes.

Narrative guideline changes appear in bold text in this document.

What Can You Do?

For Coding and Clinical Documentation Integrity professionals, reading the new guidelines should be a requirement on your summer reading list. In addition to identifying the bolded text, pay attention to each time the guidelines tell you to query the provider if documentation is unclear.

For example, Section 1.A.19: Code Assignment and Clinical Criteria

“The assignment of a diagnosis code is based on the provider’s diagnostic statement that the condition exists. The provider’s statement that the patient has a particular condition is sufficient. Code assignment is not based on clinical criteria used by the provider to establish the diagnosis. If there is conflicting medical record documentation, query the provider.”

Finally, be sure to share this information with your Coding and Clinical Documentation Integrity staff as part of their preparedness plan for the October 1^st start of the 2024 CMS Fiscal Year.

There are five covered indications in section B of National Coverage Determination (NCD) 20.7 Percutaneous Transluminal Angioplasty (PTA) for when PTA is covered.  

In June 2022, the Multispecialty Carotid Alliance (MSCA) submitted a letter to CMS for reconsideration of covered indication B4 (concurrent with carotid stent placement in patients at high risk for carotid endarterectomy (CEA).

Last week, on July 11, 2023, CMS published Proposed Decision Memo CAG-00085R8: Percutaneous Transluminal Angioplasty (PTA) of the Carotid Artery Concurrent with Stenting. CMS notes, the scope of this reconsideration is limited to PTA concurrent with CAS including transcarotid artery revascularization (TCAR) procedures.

CMS summarizes that their proposals, which affect NCD 20.7 sections B4 and D, will revise Medicare coverage for PTA of the carotid arteries concurrent with stenting by:

1. Expanding coverage to individuals previously only eligible for coverage in clinical trials.
2. Expanding coverage to standard surgical risk individuals by removing the limitation of coverage to only high surgical risk individuals.
3. Removing facility standards and approval requirements.
4. Adding formal shared decision-making with the individual prior to furnishing CAS; and
5. Allowing MAC discretion for all other coverage of PTA of the carotid artery concurrent with stenting not otherwise addressed in NCD 20.7.

CAS By the Numbers

Moving Forward

CMS is seeking comments on whether the shared decision-making interaction should require the use of a validated shared decision-making tool and/or if there are other options to achieve the goal of truly informed decision-making. The comment period is from July 11, 2023 through August 10, 2023.

June 22, 2023: MLN MM13216: Ambulatory Surgical Center Payment System: July 2023 Update – Revised

It has been almost four years since the September 30, 2019 publication of the Discharge Planning Conditions of Participation (CoP) Final Rule in the Federal Register. At that time, CMS indicated that they would provide sub-regulatory interpretive guidance after the publication of the final rule, which will provide further clarification for implementing the final discharge planning requirements. You can read more about this final rule in a related MMP article.

In 2020, COVID-19 was declared a Public Health Emergency (PHE), and CMS used emergency waiver authorities so providers could rapidly respond to people impacted by COVID-19. Specific to the Discharge Planning CoPs, CMS waived the following requirements:

§482.43(A)(8) Quality and Resource Use Measures

“The hospital must assist patients, their families, or the patient’s representative in selecting a post-acute care provider by using and sharing data that includes, but is not limited to, HHA, SNF, IRF, or LTCH data on quality measures and data on resource use measures. The hospital must ensure that the post-acute care data on quality measures and data on resource use measures is relevant and applicable to the patient’s goals of care and treatment preferences.”

§482.43 (C)(1) Patient Choice Lists

“The hospital must include in the discharge plan a list of HHAs, SNFs, IRFs, or LTCHs that are available to the patient, that are participating in the Medicare program, and that serve the geographic area (as defined by the HHA) in which the patient resides, or in the case of a SNF, IRF, or LTCH, in the geographic area requested by the patient. HHAs must request to be listed by the hospital as available.”

§482.61(e): Discharge Planning and Discharge Summary

“The record of each patient who has been discharged must have a discharge summary that includes a recapitulation of the patient’s hospitalization and recommendations from appropriate services concerning follow-up or aftercare as well as a brief summary of the patient’s condition on discharge.”

The discharge planning waivers expired on May 11, 2023 at the end of the COVID-19 PHE.

On June 6, 2023, CMS issued a Memorandum (QSO-23-16-Hospitals) to State Survey Agency Directors and noted in the Memorandum Summary that:

“CMS is committed to ensuring that the health and safety of patients are protected when discharges from hospitals and transfers to post-acute care providers occur. Therefore, we are providing the following information:

• Reminding state agencies (SAs), accrediting organizations (AOs), and hospitals of the regulatory requirements for discharges and transfers to post-acute care providers.
• Highlighting the risks to patients’ health and safety that can occur due to an unsafe discharge.
• Recommendations that hospitals can leverage to improve their discharge policies and procedures to improve and protect patients’ health and safety.”

   

  Areas of Concern

  Examples from the list of concerns identified by CMS related to missing or inaccurate patient information includes:

• Incomplete comprehensive list of all medications that have been prescribed to a patient during, and prior to, the hospitalization,
• Skin tears, pressure ulcers, bruising, or lacerations, including orders or instructions for cultures, treatments, or dressings, and
• A patient’s preferences and goals for care, such as their choices for treatment or their advance directives for end-of-life care.

After noting how missing and inaccurate patient information can have a negative impact for the patient, caregiver, and PAC providers, CMS reminds SAs and AOs about the discharge planning CoPs and advises that “when conducting surveys, SAs and AOs should be alert to the common issues identified above and ensure these discharges are occurring in a compliant and safe manner.”

Moving Forward

As of June 20, 2023, interpretive guidance for the Discharge Planning CoPs is still “pending and will be updated in future release” of the State Operations Manual – Appendix A – Survey Protocol, Regulations, and Interpretive Guidelines for hospitals. In the meantime, I encourage you to share this memorandum with your Discharge Planning staff so they can use the full list of areas of concern to make sure your medical record does not have missing or inaccurate patient information.

Did You Know?

CMS recently published ICD-10-PCS and ICD-10-CM files for Fiscal Year 2024. Changes to the codes will be in effect for discharges occurring from October 1, 2023, through September 30, 2024.

ICD-10-PCS Files

The 2024 ICD-10-PCS files (https://www.cms.gov/medicare/icd-10/2024-icd-10-pcs) and FY 2024 ICD-10-PCS Guidelines for Coding and Reporting were published as of June 6, 2023.  

For FY 2024, there are 78 new codes and 5 deleted codes bringing the total number of ICD-10-PCS codes to 78,603. Note, with an increase of 40 codes for FY 2024, New Technology codes make up more than 50% of the new codes.

One change noted when compared to the FY 2023 PCS guidelines is in the Device General Guidelines section B6.1a. This section provides guidance that “if a device that is intended to remain after the procedure is completed requires removal before the end of the operative episode in which it was inserted, both the insertion and removal of the device should be coded.”

The FY 2023 guidelines included an example of when you would code both the insertion and the removal “(for example, the device size is inadequate or an event documented as a complication occurs).” The example has been removed from the FY 2024 guidelines.  

ICD-10-CM Files

The ICD-10-CM files (https://www.cms.gov/medicare/icd-10/2024-icd-10-cm) became available on June 16, 2023. For FY 2024, there are 395 new codes and 25 deleted codes bringing the number of ICD-10-CM codes to 74,044.

CMS noted in their announcement that the FY 2024 ICD-10-CM Coding Guidelines, FY 2024 Conversion Table and FY 2024 Present on Admission (POA) Exempt Code List will be posted when available.

Why it matters?

CMS notes, on the opening page of the 2024 ICD-10-PCS Official Guidelines for Coding and Reporting, “These guidelines have been developed to assist both the healthcare provider and the coder in identifying those procedures that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved.”

What can I do?

Share this information with coding and clinical documentation professions at your facility as you begin to prepare for the October 1, 2023, start of the CMS FY 2024.

Did You Know?
According to the American Lung, about 10 to 30% of adults in the U.S. may have sleep apnea and your risk increases with age and weight. One relatively new treatment for this condition is Hypoglossal Nerve Stimulation (HNS).

Effective January 1, 2022, there were three new CPT codes related to implantation, revision, or removal of the HNS system. A few months later, on June 7, 2022, the first RAC approved issue in 2022 was RAC Issue 0201 (Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea: Medical Necessity and Documentation Requirements). You can read more about this in a related MMP article.

The affected CPT code for RAC Issue 0201 is 64582 (open implantation of hypoglossal nerve neurostimulator array, pulse generator and distal respiratory sensor electrode or electrode array). The following table highlights the place of service, volume and claims paid in CY 2022 for this CPT code.  

Why It Matters?

Medicare Administrative Contractors (MACs) have published Local Coverage Determinations (LCDs) and related coding and billing articles for this procedure. Currently, two of the indications are a body mass index (BMI) less than 35 kg/m2, and a polysomnography (PSG) demonstrating an apnea-hypopnea index (AHI) of 15 to 65 events per hour within 24 months of initial consultation for HNS implant.

In the U.S. Food & Drug Administration’s June 9, 2023 FDA Roundup, they announced they have approved an expanded indication for the Inspire Medical Systems’ Inspire Upper Airway Stimulation (UAS) System to include an updated AHI and BMI threshold.

“The safety and effectiveness data available now increased the AHI baseline to 100 and a BMI level of 40 for adults with moderate to severe Obstructive Sleep Apnea (OSA).”

What Can I Do?

With this device being on the RAC approved issue list you should:

• Be mindful of the timing of the FDA’s expanded indications in the event you receive a request for records for dates of service on or after June 9, 2023.
• Watch for updated indication information in your MACs related LCD.
• Share this information with key stakeholders.

FDA Roundup: June 9, 2023: https://www.fda.gov/news-events/press-announcements/fda-roundup-june-9-2023

Did You Know?

June is cataract awareness month and according to the National Eye Institute (https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/cataracts), most cataracts are age-related, there are no early symptoms of cataracts and later symptoms includes blurry vision, colors that seem faded, sensitivity to light, trouble seeing at night and double vision.

A cataract is diagnosed by a dilated eye exam and the treatment is surgery. Cataract surgery is one of the most common operations in the United States. In fact, more than half of all Americans aged eighty or older either have cataracts or have had surgery to get rid of cataracts.

Why it Matters?

Being a high-volume surgery, means scrutiny by CMS and Medicare Contractors to assure documentation in the medical record supports medical necessity of the procedure.

Recovery Audit Contractors

RAC Issue 0002 cataract removal (https://www.cms.gov/Research-Statistics-Data-and-Systems/Monitoring-Programs/Medicare-FFS-Compliance-Programs/Recovery-Audit-Program/Approved-RAC-Topics-Items/0002-Cataract-Removal-Medical-Necessity-and-Documentation-Requirements) has been an approved complex review for procedures performed in the outpatient hospital setting and ambulatory surgery centers (ASCs) since February 1, 2017. RACs will review documentation to determine if cataract surgery meets Medicare coverage criteria, meets applicable coding guidelines, and/or is medically reasonable and necessary. Applicable National Coverage Determinations (NCDs), Local Coverage Determinations (LCDs), and Local Coverage Articles (LCAs) are included on this RAC issue webpage.

Comprehensive Error Rate Testing (CERT)

In the 2021 and 2022 CERT Medicare Fee-for-Service supplemental improper payment report, cataract removal and lens insertion is listed in Table D1: Top 20 Service Types with Highest Improper Payments: Part B (https://www.cms.gov/files/document/2021-medicare-fee-service-supplemental-improper-payment-data.pdf-0).

2021 CERT Report

The improper payment rate for this surgery was 12.7%. The CERT cited two types of errors, insufficient documentation, and incorrect coding, as being the cause of improper payments. Specifically,

the insufficient documentation project improper payment was $190,495,888 and the incorrect coding improper payment was $27,844,602.

2022 CERT Report

The improper payment rate for this surgery was 8.3%. Unlike 2021, 100% of the errors were due to insufficient documentation. The project improper payment rate was $146,067,233.

Medicare Administrative Contractors (MACs)

JE and JF MAC: Noridian

Cataract surgery has been a review target for Noridian MAC jurisdictions for a few years. Their most recent review findings were for claims with dates of service from January 1, 2023 through March 31, 2023.

Review results for jurisdictions were published April 12, 2023:

• Noridian JE error rate of 48.67%. https://med.noridianmedicare.com/web/jea/cert-review/mr/review-results
• Noridian JF error rate 45.88%. https://med.noridianmedicare.com/web/jfa/cert-review/mr/review-results

Noridian’s review results articles include top denial reasons, educational resources, and education regarding the medical necessity for cataract surgery.

Supplemental Medical Review Contractor (SMRC)

On February 16, 2022, the SMRC published a notification of their intent to review cataract surgeries performed in the physician office, outpatient hospital and specialty facility clinical access hospitals. In the background section of the notification, they note that “this type of surgery has been a topic of interest for the Office of Inspector General (OIG) for a number of years. The OIG looked into surgery in both the outpatient facility and ambulatory service center settings. CMS data reflects a potential vulnerability.”

The SMRC published review results on September 27, 2022 (https://noridiansmrc.com/completed-projects/01-302/). The error rate was 51%.

What Can You Do?

With so many entities focused on reviewing cataract surgery claims, moving forward providers should:

• Respond to ADRs in a timely manner,
• Become familiar with medical necessity indications and documentation requirements detailed in Medicare coverage documents (NCDs, LCDs, LCAs),
• Be aware of who is performing cataract surgery reviews,
• Read published review results to understand reasons for denials and ways to prevent future denials, and
• Ensure physicians performing these procedures are also aware of Medicare coverage requirements.

Question:

How do you code provider documentation of CKD G4A3?  Is this the same as stage 4 chronic kidney disease?  The provider also noted an estimated glomerular filtration rate of 25 (eGRF25).

Answer:

Yes.  According to Coding Clinic, provider documentation of CKD G4A3 is the same as stage 4 chronic kidney disease.  This is a new categorization of CKD referred to as CGA staging, and is based on the cause (C), glomerular filtration rate (G) and albuminuria (A).  CGA provides a more detailed description of the patient’s CKD.  The number following (G) describes the stage of the CKD. 

The effective date for this guidance begins with April 1, 2023 discharges.

Refer to the following link for more information regarding the CGA classification:  http://ckdpathway.ca/Content/pdfs/Classification_of_CKD.pdf
