Risk adjustment is hugely important in Medicare Advantage (MA). Risk adjustment is intended to financially adjust taking into account the underlying severity of beneficiaries’ health conditions and appropriately compensate private insurers with vastly varying expectations for expenditures. In each year, plans receive higher payments in direct proportion to documented risk: A 5 percent increase in documented risk leads to a 5 percent increase in payment. Yet, because MAO have considerable control over the documentation, it is common for insurers to erroneously document patient risk and receive inflated payments from CMS, at least according to several CMS and OIG Reports.

Enter Risk Adjustment Data Validation (RADV) audits.

These are the main corrective action for overpayments made to Medicare Advantage organizations (MAO) when there is a lack of documentation in the medical record to support the diagnoses reported for risk adjustment

CMS has conducted contract-level RADV audits by selecting about 30 contracts for audit annually (roughly 5 percent of MA contracts). CMS then selects samples from each contract of up to 201 beneficiaries divided into three equal strata (low, average, and high risk). Auditors then comb through each beneficiary’s medical records to determine whether diagnoses that the MA plan submitted are supported by documentation in the medical record. From this process, auditors can calculate an error rate for the sample, which can then be extrapolated to the rest of the contract. For instance, if auditors determine that an insurer overcoded a sample’s risk by 5 percent, auditors could infer that plans under that contract were overpaid by 5 percent. Historically, however, CMS has only sought to collect the overpayments identified for the sample of audited beneficiaries. Not any more!

A CMS Final Rule, published February 1, 2023, addresses extrapolation, CMS’ decision to not apply a fee-for-service (FFS Adjuster) in RADV audits, and the payment years in which these policies will apply. Once it goes into effect on April 3, 2023, CMS estimates it will result in the recoupment of $4.7 billion in overpayments from MA insurers over the next decade.

As for extrapolations, CMS will not extrapolate RADV audit findings for PY 2011-2017 and will begin collection of extrapolated overpayment findings for any CMS and OIG audits conducted in PY 2018 and any subsequent payment year.

The improper payment measurements conducted each year by CMS that are included in the HHS Agency Financial Report, as well as audits conducted by the HHS-OIG, have demonstrated that the MA program is at high risk of improper payments. In fiscal year (FY) 2021 (based on calendar year 2019 payments), OIG calculated that CMS made over $15 billion in Part C overpayments, a figure representing nearly 7 percent of total Part C payments.

The HHS-OIG has also released several reports over the past few years that demonstrate a high risk of improper payments in the MA program.

Looking forward – Expect more MAO audits.
