Did You Know?

Livanta, the National Medicare Claim Review Contractor, samples claims for review monthly for short stay reviews (SSRs) and higher weighted DRG (HWDRG) reviews. As part of their Provider Education efforts, they publish a monthly newsletter called The Livanta Claims Review Advisor.

The first Claims Review Advisor newsletter was published two years ago this month in February 2022. Livanta noted in that newsletter that it is meant “to share its review findings and provide guidance to healthcare organizations…each month’s content will highlight areas of interest for medical coders, billing professionals, clinical documentation improvement (CDI) professionals, physicians, and other practitioners.” Topics alternate between SSRs and HWDR reviews each month.

Why It Matters?

Livanta recently released the January 2024 edition of The Livanta Claims Review Advisor with a focus on SSRs for electrolyte abnormalities. You will find error rates by MS-DRG, example scenarios of specific electrolyte abnormalities (i.e., hyperglycemic emergencies), and guidance for documenting “the reasonableness of a two-midnight expectation at the time of inpatient admission: regardless of the MS-DRG.

Error Rates

Overall, Livanta completed 1,985 reviews for dates of service from October 2021 through December 2023 for the following MS-DRGs:

• MS-DRG 637: Diabetes with MCC,
• MS-DRG 638: Diabetes with CC,
• MS-DRG 639: Diabetes without CC/MCC,
• MS-DRG 640: Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes with MCC (error rate 10.20%), and
• MS-DRG 641: Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCC.

MS-DRG 641 had the highest reported error rate at 11.60%.

How Big is the Pool of Claims?

Based on claims data provided by our sister company RealTime Medicare Data (RTMD), in the CMS FY 2023 (October 1, 2022 through September 30, 2023) for all fifty states and Washington D.C. combined, there were 73,497 claims that grouped to one of the above MS-DRGs. The total payment made to providers for this group of claims was $481,535,832.43.

Note, claims with a discharge disposition of expired (20), transfer to another acute care facility (02), transfer to a short-term general hospital with planned acute hospital inpatient readmission (82), left against medical advice (07), and hospice election (50 & 51) have been excluded from this data as CMS considers these to be “unforeseen circumstances.” I have included MS-DRG specific claims data in the table at the end of this article.

What Can You Do?

• Read the January 2024 of The Livanta Claims Review Advisor and share with key stakeholders at your facility.
• Review a sample of short stay claims to determine if documentation supported the inpatient admission or if care could have been provided on an outpatient basis.
• View past editions of this newsletter at https://www.livantaqio.cms.gov/en/ClaimReview/Provider/provider_education.html, and
• If you have not signed up to received Livanta’s publications, I encourage you to do so at https://www.livantaqio.cms.gov/en/ClaimReview/Provider/bulletin.html.

The Program for Evaluating Payment Patterns Electronic Report or PEPPER is one resource available to providers to help guide your selection of meaningful review targets for audits. According to the PEPPER User’s Guide for Short-Term Acute Care, this report “contains a single hospital’s claims data statistics for Medicare-Severity Diagnosis-Related Groups (MS-DRGs) and discharges at risk for improper payment due to billing, coding, and/or admission necessity issues…All of the data tables, graphs, and reports in PEPPER were designed to assist the hospital in identifying potential overpayments as well as potential underpayments.”

If you attempted to access the PEPPER Resources website in December 2023, you were directed to a blank page. This week I once again checked this website and the following notice has been posted:

“Updates to the Program for Comparative Billing Reports (CBRs) and Evaluating Payment Patterns Electronic Report (PEPPERs) Coming Soon

There will be a temporary pause in distributing CBRs and PEPPERs as CMS works to improve and update the program and reporting system. This pause will remain in effect through the fall of 2024. We recognized the importance of these reports to your practice. Therefore, during this time, CMS will be working diligently to enhance the quality and accessibility of the reports. In fulfilling this commitment, your feedback is requested. In the near future, CMS will release a Request for Information (RFI) to obtain information from you, the provider community, about how the program can better serve you.

Please visit CBR and PEPPER website for periodic updates. If you have further questions please send them to Medicaremedicalreview@cms.hhs.gov.”

About CBRs

Question:

Are there any updates for rehabilitative therapy services’ threshold amounts for the coming year?

Answer:

Yes. Change Request (CR) 13371 issued September 14, 2023 and re-communicated November 6, 2023 updates the annual per-beneficiary incurred expenses amounts now called the KX modifier thresholds and related policy for CY 2024. These thresholds were previously known as “therapy caps.”

CY 2024 KX Modifier Threshold Amounts

1. $2,330 for Physical Therapy (PT) and Speech-Language Pathology (SLP) services combined, and
2. $2,330 for Occupational Therapy (OT) services.

Providers can track a patient’s year-to-date therapy amounts on Medicare eligibility screens. The KX modifier must be appended to therapy services’ line-items on the claim for medically necessary therapy services above the threshold amounts. The medical necessity of services beyond the threshold amount must be justified by appropriate documentation in the medical record. Services provided beyond the threshold that are not billed with the KX modifier will be denied with Claim Adjustment Reason Code 119 - Benefit maximum for this time period or occurrence has been reached.

There is also a therapy threshold related to the targeted medical review process, now known as the Medical Record (MR) threshold amount. This threshold remains at $3,000 for PT and SLP combined and a separate $3,000 for OT until CY 2028.

Did You Know?

CMS announced in the CY 2024 Physician Fee Schedule (PFS) Final Rule, effective January 1, 2024 that they are pausing their efforts to implement the Appropriate Use Criteria (AUC) Program for reevaluation and rescinding the AUC regulations at 42 CFR 414.94, reserving this section for future use.

Why It Matters?

On November 3, 2023, CMS posted the following notice on the AUC Program webpage:

“Effective January 1, 2024, providers and suppliers should no longer include AUC consultation information on Medicare FFS claims. Additionally, CMS will no longer qualify PLEs or CDSMs and will remove this information from the AUC website. The claims processing instructions and guidance for the educational and operations testing period will also be removed.”

What Can I Do?

Share this information with the appropriate stakeholders at your facility and consider this an early Thanksgiving blessing that CMS acknowledged the challenges to implementing the regulations at 42 CFR 414.94.

CMS issued the CY 2024 OPPS/ASC Final Rule on November 2, 2023. You can read about changes to the Inpatient Only (IPO) Procedure List and ASC Coverage Procedure List (CPL) in a related article in this week’s newsletter. This article highlights additional topics that historically our clients have reached out to us to learn about.

OPPS Remedy for 340B-Acquired Drug Payment Policy

On July 7, 2023, CMS published a proposed rule, referred to as “remedy proposed rule” to address reduced payment amounts to 340B hospitals for CYs 2018 through 2022 and to comply with the statutory requirement to maintain budget neutrality. The “remedy proposed rule” proposed changes to the calculation of the OPPS conversion factor beginning in CY 2025.

The 340B final remedy was also issued on November 2^nd. In this final rule, CMS finalized their proposed methodology of estimating the reduction in drug payments to affected 340B covered entity hospitals in CY 2018 through September 27, 2022, and will make total lump sum payments in the amount of $9.004 billion.

CMS will be issuing instructions to the MACs to issue a one-time lump sum payment to the affected hospitals within 60 calendar days of the MAC’s receipt of the instructions.

Based on updated analyses, the final rule Addendum AAA was updated with new hospital-specific payment amounts and accounts for all payment activity that has happened since the proposed rule was issued. Updated claims data reflects that affected hospitals received approximately $10.6 billion less in 340B drug payments (including money that would have been paid by Medicare and money that would have come from the beneficiaries as copayments) than they would have for drugs provided in CY 2018 through September 27, 2022, had the 340B policy not been implemented.

“The amounts included in Addendum AAA are the amounts that hospitals will receive, except that payment amounts may be affected by MACs continuing to follow normal accounting processes for collecting repayment amounts stemming from provider-specific overpayment obligations, adjustments resulting from errors identified through the lump-sum technical correction process described below, as well as other unique situations such as provider bankruptcy or payment suspension, any of which may impact the provider’s net payment amount.”

Unfortunately, the lump sum payments do not include interest and CMS is following budget neutrality requirements to make these payments. This means that “beginning in CY 2026, we will reduce all payments for non-drug items and services to all OPPS providers, except new providers (hospitals with a CMS CCN effective date of January 2, 2018, or later), by 0.5 percent each year until the total estimated offset of $7.8 billion is reached. We currently estimate that the payment decrease will be completed after approximately 16 years. To implement this reduction and exception for new providers, we are finalizing the proposed regulation text changes at § 419.32(b)(1)(iv)(B) as proposed, except for changing the implementation date of the 0.5 percent reduction from CY 2025 to CY 2026.”

CMS notes in the 340B remedy final rule that “generally the impact of that annual 0.5 percent reduction to the OPPS conversion factor on individual providers, as well as categories of providers, will depend on the percentage of their OPPS payments that are conversion factor-based, and in most cases will be a decrease of slightly less than 0.5 percent of overall OPPS payments.”

Beneficiary Cost Sharing

CMS noted in the final rule that commenters overwhelmingly supported their proposed approach and rationale for accounting for beneficiary cost sharing. They finalized their “policy to account for beneficiary cost sharing as proposed. We will exercise our authority under section 1833(t)(2)(E) of the Act (42 U.S.C. 1395l(t)(2)(E)) to make adjustments “as necessary to ensure equitable payments,” to pay the full $9.0 billion difference, including $1.8 billion, an amount that is approximately equivalent to what affected 340B covered entity hospitals would have collected from beneficiaries for these 340B-acquired drugs if the 340B Payment Policy had not been in effect from CY 2018 through September 27, 2022, so that affected 340B covered entity hospitals are paid the approximate amount they would have been paid in full without application of the 340B Payment Policy.”

340B Modifiers “JG” and “TB”

The Inflation Reduction Act of 2022 expanded the provider types that must report one of these modifiers no later than January 1, 2024, to now include critical access hospitals, Maryland All-Payer or Total Cost of Care Model Hospitals, and Non-excepted off-campus provider-based departments (PBD).

In the CY 2023 OPPS/ASC final rule, CMS maintained the requirements that 340B hospitals report one of two modifiers, “JG” – Drug or biological acquired with 340B drug pricing program discount, reported for informational purposes, or “TB” – Drug or biological acquired with 340B drug pricing program discount, reported for informational purposes for select entities.

In the CY 2024 OPPS/ASC proposed rule, CMS notes they “now believe utilizing a single modifier will allow for greater simplicity, especially because both modifiers are used for the same purpose: to identify separately payable drugs and biologicals acquired under the 340B program.”

CMS is proposing that all 340B covered entity hospitals would report the “TB” modifier effective January 1, 2025, even if the hospital previously reported the “JG” modifier. The “JG” modifier will remain effective through December 31, 2024. Beginning January 1, 2025, the “JG” modifier would be deleted.

CMS notes hospitals currently using the “JG” modifier could choose to continue to use it in CY 2024 or choose to transition to the “TB” modifier during that year.
