NEW RISK AREA - TOTAL KNEE REPLACEMENT

Last Wednesday December 2nd, the Program for Evaluating Payment Patterns Electronic Report (PEPPER) Team sent out a notice to list serve recipients informing them that the Q3 Fiscal Year 2020 PEPPER Report for Short-Term Acute Care Hospitals was recently completed. It is important to note that your hospital specific report will only be available for download until December 14, 2020 as the QualityNet file transfer service will be decommissioned on December 15th. If you do not download the report before the deadline, the report will not be available until the next release scheduled for March 8, 2021.

This article focuses on the Short-Term Acute Care Hospitals PEPPER. Specifically, the changes in the recently released Fiscal Year (FY) 2020 Q3 Short-Term Acute Care PEPPER and an analysis of Palmetto JJ Total Knee claims. But first, for those not familiar with the PEPPER, let’s take a look at what it is and why it is a valuable resource for hospitals.  

Background

What is PEPPER?

The PEPPER contains statistics for specific “Target Areas” that have been identified as being “at risk for improper payment due to billing, coding and/or admission necessity issues.” The Centers for Medicare & Medicaid Services (CMS) approves the Short Term PEPPER target areas.

The PEPPER compares you to other hospitals in your state, Medicare Administrative Contractor (MAC) Jurisdiction and to the nation. “Comparisons enable a hospital to determine if it is an outlier, differing from other short-term acute care hospitals.” Reports are delivered to a hospital electronically, are hospital specific, and provide the most recent twelve federal fiscal quarters for each target area.

In addition to your hospital specific report, the PEPPER Resources National-level Data Reports webpage includes a Target Area Analysis that provides claims volume, average length of stay and average Medicare Payment for each of the target areas.

Why is this a Valuable Resource for your Hospital?

The PEPPER User’s Guide notes that the Office of Inspector General (OIG) “encourages hospitals to develop and implement a compliance program to protect operations from fraud and abuse. As part of a compliance program, a hospital should conduct regular audits to ensure charges for Medicare services are correctly documented and billed.”

It is important to understand that “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,
• Changes in lengths of stay.”

PEPPER User’s Guide, 31st Edition, effective with Q3FY 2020 Release, What’s New?

The 31st Edition of the PEPPER User’s Guide includes a new target area called Total Knee Replacement. Following are the Total Knee Target Area definitions for the numerator and denominator in the User’s Guide:

• Numerator: the count of discharges with at least one of the ICD-10-PCS knee replacement procedures codes in Appendix 6 of the User’s Guide.
• Denominator: the count of discharges with at least one of the ICD-10-PCS knee replacement procedure codes plus outpatient claims with CPT® code 27447.

The CY 2018 OPPS Final Rule finalized the removal of this procedure from the Medicare Inpatient Only (IPO) List. This new target area will monitor the proportion of all knee surgeries that are performed on an inpatient basis in short-term acute care hospitals.

The User’s Guide indicates that high outlier hospitals may have “unnecessary admissions related to the use of outpatient observation or inappropriate use of admission screening criteria associated with total knee replacement procedures. A sample of medical records for these procedures should be reviewed to determine whether care could have been provided more efficiently on an outpatient basis. Documentation should support the need for an inpatient admission.”

RealTime Medicare Data (RTMD) Analysis of Total Knee Claims

In addition to total knee procedures being a new PEPPER Target Area, Total Knee Arthroplasty Medical Necessity and Documentation Requirements Reviews became an approved RAC Issue (0185) on August 3, 2020. The RACs will be performing complex medical reviews for inpatient hospital, outpatient hospital, ambulatory surgical center and professional services.

Given that Total Knee Claims seem to be an ongoing review for Medicare Contractors, I turned to our sister company, RTMD, to perform an analysis of Total Knee claims for Palmetto GBA Jurisdiction J which includes Alabama, Georgia and Tennessee. Specifically parameters of my analysis included:

• Claims with dates of service from January to June for calendar years 2017 (the year prior to total knee procedures being removed from the Medicare Inpatient Only (IPO) list) through 2020.
• Total knee inpatient claims with the list of ICD-10-PCS knee replacement codes found in Appendix 6 of the User’s Guide, and
• Total knee outpatient claims with a CPT® code 27447, again as per the parameters of the PEPPER Review Target. This is important to keep in mind as the RAC issue also includes additional knee procedure CPT® codes 27445, 27486 and 27487.

Key Findings

• While there were outpatient claims in all three states in 2017, in general hospitals received no payment for CPT 27447.
• All three states have seen a shift from inpatient to outpatient total knee claims with the most significant shift being in Georgia.
• Inpatient volumes appear to have been impacted more as a result of the COVID-19 pandemic.

Potential Next Steps

• Download your PEPPER Report prior to December 15, 2020.
• Whether or not you are an outlier, consider reviewing a sample of claims for documentation supporting the billing patient status and medical necessity of the surgical procedure.
• Prior to reviewing a sample of claims, determine whether or not your MAC has created a Local Coverage Determination (LCD) and Local Coding and Billing Coverage Article (LCA) for total knee procedures.
• I encourage you to spend some time on the PEPPER Resources website where you can find a copy of the most recent User’s Guide, Training and Resources available to you including testimonials and training sessions.
• One last resource, at the same time Total Knee Procedure became an approved issue for the RACs, CMS released an updated Major Joint Replacement (Hip or Knee) MLN Booklet in August. This is a useful tool as it provides information related to documentation, coverage requirements and coding major joint replacements.
