Insights for Remaining Audit Ready: CMS Releases 2021 Audit Enforcement Report

On June 7, 2022, the Centers for Medicare and Medicaid Services (CMS) released the 2021 Part C and Part D Program Audit and Enforcement Report, providing details of the 2021 audit cycle.[1] The enforcement report provides analyses and information that sponsors and stakeholders can use for continuous improvement efforts within their organizations. Sponsors and stakeholders are wise to use the information to prevent noncompliance by accessing risks and operational vulnerabilities and conducting the necessary monitoring and auditing to maintain program audit readiness.

The Difference a Year Makes

CMS audited 27 plans in 2021, significantly more than what was audited in 2020, as the COVID-19 public health emergency (PHE) limited their ability to audit as many plans. The CMS 2021 audit strategy does not contain any year-to-year comparisons between audits, as the 2020 audit strategy had many challenges due to the PHE. Therefore, CMS cautioned against using the enforcement report to draw broad conclusions about the significance of deficiencies or performance across Medicare Advantage (MA), Part D or Medicare-Medicaid Plan (MMP) programs.

Audit Insights

CMS provided sponsors with insights to help prepare for a CMS program audit. The following are some audit insights and tips, as well as observations made during the 2021 enforcement referrals to strengthen overall compliance programs:
