The CMS Review Choice Demonstration for Inpatient Rehabilitation Facility (IRF) Services is set to begin in Alabama in August 2023. You can read more about the program and choices that Alabama IRF providers will need to make in a related article in this week’s newsletter.

This article looks back at past IRF claims reviews and resources available to providers on Palmetto GBA’s website, the Medicare Administrative Contractor (MAC) for Alabama.

Prior IRF Claims Reviews

Office of Inspector General (OIG)

In September 2018, the OIG published the report “Many Inpatient Rehabilitation Facility Stays Did Not Meet Medicare Coverage and Documentation Requirements” (A-01-15-00500). The audit covered $6.75 billion in Medicare payments to 1,139 IRFs nationwide for 370,872 IRF stays. The objective was to determine if IRFs complied with Medicare coverage and documentation requirements for claims for services provided in 2013. Based on sample results, the OIG estimated that Medicare paid IRF’s $5.7 billion for care to beneficiaries that was not reasonable and necessary.

The OIG noted errors occurred because many IRFs did not have adequate internal controls to prevent inappropriate admissions; Medicare Part A FFS lacked a prepayment review for IRF admissions and CMS’ extensive educational efforts and post payment reviews were unable to control an increasing improper payment rate reported by CERT.

Supplemental Medical Review Contractor (SMRC)

Based on the 2018 OIG report findings, CMS tasked Noridian, the current SMRC, to complete a review of Medicare Part A IRF claims for CY 2018 claims. Noridian published their review results in October 2021 and reported a 33% error rate. I encourage you to read their review results as it includes common reasons for denial and references and resources.

Comprehensive Error Rate Testing (CERT)

The OIG noted in the above 2018 report the CERT program found that the error rate for IRFs had increased, ranging from 9 percent in 2012 to a high of 62 percent in 2016. Although the error rate has decreased in subsequent years, the Improper Payment Rate remained high at 19.3 percent in 2022 with close to $7M projected improper payments.

Active OIG Work Plan Item: Inpatient Rehabilitation Facility Nationwide Audit

In this active issue description, the OIG notes that in fiscal year 2021, Medicare paid approximately $8.7 billion for 373,000 IRF stays nationwide. The CERT has consistently found high error rates, and their Hospital Compliance audits also frequently include IRF claims and have similarly found high error rates.

“In response to these findings, IRF stakeholders have stated that Medicare audit contractors and OIG have misconstrued the IRF coverage regulations. To better understand which claims IRFs believe are properly payable by Medicare, OIG needs more information from the IRF stakeholders. We plan to determine whether there are areas in which CMS can clarify Medicare IRF claims payment criteria. In addition, we will follow up on recommendations from our prior IRF audit, A-01-15-00500. We believe data and input from IRF stakeholders are critical to identifying any specific areas that might require clarification and will result in more meaningful recommendations and a greater positive impact on the program.”
