CMS-0062-P: drug prior authorization through the API by October 1, 2027, if finalized

Short answer: CMS-0062-P would put medical-benefit drugs on the FHIR Prior Authorization API and pharmacy-benefit drugs on NCPDP standards from October 1, 2027, with a specific denial reason and 24-hour and 72-hour drug clocks for exchange plans. Proposed, not final.

What the rule proposes

One rule, two drug tracks

CMS-0057-F left drugs out of every 2027 API [2]. CMS-0062-P, released April 10, 2026, closes the gap by benefit type.

FAQ

Frequently asked questions

What is CMS-0062-P?

A proposed rule from CMS and ONC, published in the Federal Register on April 14, 2026, that would require impacted payers to support electronic prior authorization for all drugs through the Prior Authorization API (medical-benefit drugs) and NCPDP standards (pharmacy-benefit drugs) beginning October 1, 2027. It also proposes API endpoint reporting, drug prior authorization metrics from 2028 and a specific denial reason for drugs. It is proposed, not final.

Does CMS-0057-F already cover drug prior authorizations?

No. CMS-0057-F excludes drug prior authorizations from the Prior Authorization API, the decision timeframes and the denial reason requirement. CMS-0062-P is the proposal to extend those policies to drugs.

What are the proposed decision timeframes for drug prior authorization?

For QHP issuers on the federally facilitated exchanges, CMS proposes notice to the requesting provider no later than 72 hours for standard drug requests and 24 hours for expedited drug requests. Medicaid covered outpatient drugs already carry a 24-hour timeframe, and CMS proposes 24 hours for CHIP FFS prescription drugs. All with a proposed October 1, 2027 compliance date.

Which payers would CMS-0062-P cover?

Medicare Advantage organizations, state Medicaid and CHIP fee-for-service programs, Medicaid managed care plans, CHIP managed care entities, QHP issuers on the federally facilitated exchanges, and, newly, small group market QHP issuers on the FF-SHOP exchanges, with a proposed compliance date of plan years beginning on or after January 1, 2028 for the small group issuers.
