2027 CMS Medicare Program Audit Protocols Proposed Updates

Executive Summary: Key Takeaways

1. CMS is modernizing its audit approach—not necessarily making audits easier

Overall, CMS is reducing duplicative documentation and simplifying some universe submissions, but replacing that burden with greater reliance on:

• Higher-quality data

• Better universe accuracy

• More targeted sample selection and review processes

• Standardized root cause and impact analyses

• Increased use of desk reviews where appropriate

Implication for plans:

Organizations should expect audits to place greater emphasis on operational performance, data integrity, and accurate universe submissions, while reducing some duplicative documentation requests.

2. Compliance Program Effectiveness (CPE) becomes much more operational

One of the most significant changes is CMS' continued shift away from auditing the compliance program as a standalone function.

Instead, CPE now focuses on:

• How Compliance oversees audited operational areas

• Monitoring, auditing and investigations tied to specific audit areas

• Compliance oversight activities within a shorter lookback period (6 months)

• Consolidated questionnaires replacing separate Compliance Officer and FDR questionnaires

• Less emphasis on governance documentation and more emphasis on demonstrated oversight

Implication for plans:

Compliance departments will need to demonstrate they actively identify issues, monitor operations, escalate risks and drive corrective actions—not simply maintain policies and committee minutes.

3. CMS is incorporating recent regulatory requirements into the audit protocols

• UM prior authorization requirements

• Reopening requirements

• Coordination of benefits

• Dismissals

• Appropriate classification of cases

• Reopened determinations

• D-SNP coordination requirements

• Integrated care planning timeliness

Implication for plans:

Organizations should confirm that recent regulatory requirements have been fully operationalized, as CMS is now explicitly auditing many of these newer requirements.

4. Universe accuracy is becoming even more important

Across nearly every protocol CMS:

• Clarified inclusion/exclusion rules

• Added detailed field instructions

• Standardized layouts

• Added new data fields

• Required more precise reporting of partially favorable decisions

• Expanded reporting of reopened cases

• Included withdrawn and dismissed grievances

• Clarified notification reporting

Implication for plans:

Universe development will continue to be one of the highest-risk audit activities. Plans should expect increased scrutiny of data extraction logic, universe QA processes and data governance.

5. CMS is preparing to leverage existing CMS reporting for portions of ODAG oversight

CMS indicates its intent to use existing Service Level Data for portions of ODAG oversight once that data is available, reducing duplicative universe submissions.

CMS also removes several universes entirely, including:

• PDE data

• Certain CARA reporting

• Some Part C effectuation reporting

• Other duplicative submissions

Implication for plans:

Operational reporting submitted outside the audit process may become even more important because CMS intends to rely on those data sources during audits. Data consistency across reporting systems will become increasingly critical. 

6. Root Cause Analysis and Impact Analysis submissions are becoming more standardized

CMS replaces several embedded impact analysis tables with Excel templates that standardize expectations for documenting root cause, scope, impact, and corrective action information across protocols.

The revisions also standardize RCA and Impact Analysis submissions across protocols.

Implication for plans:

Organizations should prepare corrective action documentation that supports CMS’s standardized RCA and Impact Analysis templates. 

7. D-SNP oversight expands considerably

The SNP Care Coordination protocol includes several important additions, including new audit standards for:

• Integrated HRA requirements

• Medicaid coordination

• Notification of hospital/SNF admissions

• ICP timeliness

• Annual face-to-face requirements

• Additional D-SNP universe fields

• New questionnaire content regarding member portals and Medicaid carve-out services

Implication for plans:

D-SNP operations will receive significantly greater scrutiny, particularly around integration of Medicare and Medicaid services and care coordination processes. 

8. CMS is attempting to reduce burden while increasing consistency and efficiency

Although many changes reduce burden (fewer universes, fewer questionnaires, standardized templates, optional documents, desk reviews), CMS also increases its ability to:

• Select targeted samples

• Replace samples when needed

• Expand reviews when potential issues are identified

• Conduct audits more efficiently

• Validate corrective actions through methods other than a formal validation audit, where appropriate

CMS estimates the overall audit burden will decline substantially, even after revisions following the public comment period.

Implication for plans:

Less preparation time should not be interpreted as lower audit risk. Instead, organizations should focus investments on:

• Data quality

• Universe governance

• Operational consistency

• Corrective action effectiveness

• Cross-functional audit readiness
