ASP Insight · Prior Authorization · CMS-0057-F

The CMS-0057-F prior authorization API deadline clock is already running. Since January 1, 2026, Medicare Advantage, Medicaid, CHIP, and Federally-facilitated Marketplace QHP payers must decide expedited prior authorization requests within 72 hours and standard requests within 7 calendar days. Their first public prior authorization metrics, covering CY2025, were due March 31, 2026 and are posted now. The next milestone is January 1, 2027, when four FHIR APIs, Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization, must be live.

Who is on the clock

CMS-0057-F applies to the government-program side of the payer market. If a plan falls in one of these buckets, the 72-hour and 7-calendar-day decision timeframes already govern it, and the 2027 API mandate is coming for it next.

    Decision timeframes take effect

    Impacted payers must decide expedited prior authorization requests within 72 hours and standard requests within 7 calendar days. Every urgent request your team submits to a covered payer now carries a regulatory clock, not just a contractual one.

    First public PA metrics posted

    Public prior authorization metrics reporting for CY2025 was due March 31, 2026. For the first time, each covered payer's own prior authorization performance is published, in the payer's own numbers, on the payer's own site.

    The window to act on the data

    The metrics are public, the clocks are enforceable, and most provider organizations have not pulled either into their appeals or contracting workflows yet. This is the gap worth closing before the January 2027 API wave arrives.

    Four FHIR APIs must be live

    The Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization APIs are due January 1, 2027. The Prior Authorization API will expose documentation requirements machine-readably for the first time.

The four APIs due January 1, 2027

Patient Access API

Extends the member-facing API so patients can see their own data, including prior authorization information, through apps of their choosing.

Provider Access API

Gives in-network providers API access to payer-held data for their patients, closing the visibility gap between what the payer knows and what the practice can see.

Payer-to-Payer API

Moves member data between payers when patients switch plans, so authorization history does not evaporate at every enrollment change.

Prior Authorization API

The one that changes operations. Payers must expose whether prior authorization is required and what documentation is needed, machine-readably, so eligibility for auth can be checked in workflow instead of by phone and portal archaeology.

Why the published metrics are leverage, not trivia

For years, provider organizations argued about payer turnaround behavior with anecdotes. As of March 31, 2026, that era is over for MA, Medicaid, CHIP, and FFM QHP plans. Each covered payer has published its own CY2025 prior authorization metrics under CMS-0057-F. That means an appeal letter can now cite the payer's own published performance, and a network negotiation can put the payer's own numbers on the table next to your practice management data. When a covered payer misses the 72-hour expedited or 7-calendar-day standard timeframe on a 2026 request, you are no longer pointing at a vague industry norm. You are pointing at a federal rule, CMS-0057-F, and at the payer's own public reporting. Providers who pull, archive, and track these postings now will negotiate 2027 contracts from a different position than providers who never looked.

Operator to-do list for prior authorization teams

  1. Pull the published CY2025 PA metrics from every covered payer you are contracted with, and archive dated copies so the baseline cannot quietly change.
  2. Build a one-page payer scorecard comparing each payer's published performance against the 72-hour expedited and 7-calendar-day standard clocks.
  3. Timestamp every prior authorization submission and decision in your own system, so you can prove a clock breach independently of the payer's records.
  4. Add a standard paragraph to appeal templates citing CMS-0057-F decision timeframes and the payer's own published metrics where relevant.
  5. Rank your payers by prior authorization volume to decide which Prior Authorization API connections to build or buy first in 2027.
  6. Ask each covered payer, in writing, for its January 1, 2027 API implementation plan and developer onboarding process now, while there is still lead time.

Put the payer's own clock to work

ASP-RCM Solutions runs prior authorization operations for medical groups, therapy practices, and behavioral health organizations, including ABA practices staffed by BCBAs and RBTs. Our teams track every request against the payer's regulatory clock, build per-payer turnaround scorecards from published CMS-0057-F metrics, and fold that evidence into appeals and network negotiations. If your organization submits prior authorizations to Medicare Advantage, Medicaid, CHIP, or Marketplace plans, the leverage described on this page already exists. The only question is whether your revenue cycle is using it.
