CMS-0057-F: Modernizing Prior Authorization with FHIR and CQL

Dec 11, 2025 | Dr. Jim Shalaby

Capitalize on the CMS-0057-F Interoperability and Prior Authorization Final Rule: 

Transform Your Prior Authorization Questionnaires with FHIR and CQL for Maximum Automation

The healthcare landscape is undergoing a significant transformation with the introduction of the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F). This landmark regulation recommends the use of FHIR Questionnaires and Clinical Quality Language (CQL) for supporting electronic prior authorization requests, ushering in an era of interoperability and automation for a process long plagued by complexity and administrative burden.

While the rule primarily emphasizes HL7 Fast Healthcare Interoperability Resources (FHIR) APIs for prior authorization, the inclusion of CQL is a key innovation towards embedding computable clinical logic directly into the electronic process to automate data retrieval relevant to Prior Authorization Questionnaires.

The Indispensable Role of CQL in Prior Authorization

CQL is a high-level, domain-specific language designed to articulate clinical knowledge and quality measure logic in a way that is both human-readable and machine-executable. Its value in the new regulatory environment cannot be overstated:

  • Reduced Burden: The administrative burden of PA is a major pain point. CQL empowers payer systems to automatically query a patient’s health record (via FHIR API) for data relevant to PA criteria. This means identifying if a service requires PA, pinpointing specific supporting documentation, pre-populating prior authorization questionnaires with existing EHR data, identifying when necessary data is missing, all the while significantly reducing manual entry and errors.
  • Faster Decisions: CQL logic is a foundation for automation, which is crucial for meeting the new, stricter CMS decision timeframes: 72 hours for expedited requests and 7 calendar days for standard requests (effective January 1, 2026).

Compliance Steps for Healthcare Stakeholders

The CMS-0057-F rule impacts many stakeholders including Medicare Advantage (MA) organizations, state Medicaid programs, Medicaid managed care plans, CHIP managed care entities, and QHP issuers on the FFEs. Key compliance areas include implementing FHIR APIs and streamlining the PA process. To comply with electronic prior authorization mandates, these stakeholders must:

  1. Implement the Prior Authorization API (by Jan 1, 2027):
    • Develop and maintain a FHIR-based Prior Authorization API to support the entire ePA workflow.
    • Ensure the API can check PA requirements, identify payer-specific documentation, and support electronic submission and response.
  2. Adopt and Implement CQL Logic:
    • Questionnaire Integration: Link CQL logic to FHIR Questionnaire resources to dynamically generate and populate answers to PA criteria questions based on data in the electronic health record and quickly identify data gaps that can delay decision making
  3. Process and Workflow Changes (by Jan 1, 2026):
    • Adhere to new, shorter decision timeframes.
    • Provide a specific reason for every denial or request for additional information, facilitated by standardized CQL logic.
    • Publicly report PA process metrics starting January 1, 2026.

The Elimu Informatics Advantage: Bridging the Gap to Compliance

In essence, CQL is the language that unlocks the true utility of FHIR API requirements. It forms an essential bridge to widespread automation and a significant reduction in provider and patient burden.

This is where Elimu Informatics is an invaluable partner. Converting complex PA questionnaires into FHIR questionnaires enhanced with CQL requires specialized expertise. Elimu Informatics offers professional services to navigate this intricate conversion process, ensuring that health insurance companies can:

  • Accurately translate existing prior-authorization questionnaires into FHIR questionnaires enhanced with executable CQL for efficient electronic health data retrieval.
  • Efficiently track status of data capture PA decision making for compliance with CMS decision timeframes
  • Achieve full compliance with CMS-0057-F deadlines.
  • Optimize their prior authorization workflows for maximum efficiency and reduced administrative overhead.
