Use Case: Electronic Prior Authorization


For payers, FHIR-based ePA automates prior authorization requests, reducing manual work, and speeding decisions

The Clock is Ticking

CMS-0057-F has made one thing clear: electronic Prior Authorization (ePA) is no longer optional. By 2026, payers must support FHIR-based exchange of prior authorization requests and responses. For many organizations, the real challenge is not what  to do, it’s how  to get there without disrupting existing systems and workflows. Firely Server provides a scalable, FHIR-native foundation for ePA, enabling compliance while avoiding costly “rip-and-replace” projects.

The Problem for Payers

  1. “Rip and replace” myth

    Vendors and consultants often suggest that compliance requires re-architecting core systems and business processes. Firely strongly disagrees—ripping out everything is costly, disruptive, and unnecessary.

  2. Dual-track operations

    CMS-0057-F applies to Medicare and Medicaid lines of business, while commercial accounts must still follow existing processes, forcing payers to support two sets of workflows in parallel.

  3. Operational inefficiencies

    Without a flexible ePA strategy, payers risk labor-intensive workflows, higher rework and reprocessing rates, and missed opportunities to apply data for quality improvement.

  4. Limited FHIR expertise

    Most small to mid-sized payers lack the in-house technical bench to stand up and maintain FHIR-based workflows.

  5. Provider expectations

    Clinicians expect real-time, electronic workflows at the point of care. Manual prior auth creates friction, delays, and dissatisfaction.

The Upside of Electronic Prior Authorization for Payers

  1. Expose FHIR APIs without replacing core systems

    Firely Server enables payers to accept FHIR-based prior auth requests while continuing to process them through existing utilization management (UM) and claims systems. Think of Firely Server as a universal adapter: it plugs modern requests into your current environment, translating them into the formats and workflows you already use.

    How does it work? Firely Server connects to your existing workflows using flexible integration options, from APIs to its plugin framework, so your current business rules, intake queues, and decision engines remain intact. You get the benefits of FHIR-based interoperability on the outside, while your trusted processes continue to run on the inside.

  2. Simplify provider connectivity

    Firely Server fully supports the Da Vinci Burden reduction standards: CRD surfaces payer documentation and coverage rules at the point of order, PAS bridges FHIR and X12 so providers can submit prior auth requests electronically. It’s like moving from a dozen custom power cords to a single outlet: providers connect once, and translation happens behind the scenes, lowering integration costs and reducing provider friction.

  3. Move toward native FHIR at your pace

    Firely Server doesn’t force an all-or-nothing shift. You can continue processing requests through existing systems today, then gradually adopt native FHIR. Think of it as building a two-lane bridge: one lane connects today’s workflows, the other prepares for tomorrow’s. You can shift traffic gradually, testing and learning along the way, instead of betting everything on a single cutover. This phased approach gives you full control over timing, scope, and cost.

  4. Automate for efficiency and transparency

    Even before full ePA maturity, Firely Server enables automation that reduces manual review, accelerates turnaround times, and provides structured responses back to providers. That means fewer staff hours spent chasing documents, faster decision-making, and clearer communication with providers.

    Think of it as turning on the GPS in your workflow: instead of navigating blind with paper and faxes, both payers and providers can see where a request stands, what’s missing, and when it will be resolved. Built-in logging, analytics, and validation also give payers the visibility they need to track performance, demonstrate compliance, and identify opportunities for continuous improvement.

How Firely Server Supports Your ePA Goals

  1. Mandated FHIR APIs, ready to deploy

    The Firely Server CMS Package includes all required FHIR APIs, plus our expert-led Firely Launch program to guide your implementation.

  2. No rip-and-replace

    Use Firely’s custom plugin framework to integrate with your current intake queues, business rules, and document repositories. Next to the FHIR API, we’ll provide a CDS Hooks API allowing you to focus on implementing the business logic.

  3. Provider connectivity via PAS, CRD, and DTR

    • PAS: Translate FHIR prior auth requests into X12 transactions your backend understands.
    • CRD: Provide documentation and coverage requirements in real time before the request is submitted.
    • DTR: Allow providers to send complete, relevant clinical data right from their workflow.
  4. Automation and transparency from day one

    Automate routine checks, match documents, return structured FHIR responses, and maintain full audit logs to support compliance and improve provider satisfaction.
