Auth approved for April 15. Patient reschedules to April 28. Auth expired April 20.
The service was approved. The patient was covered. The practice did everything right. And the claim pays zero.
Expired authorization denials are the most frustrating category in billing, because nothing clinical went wrong. A date moved.
Here's what most practices don't realize changed this year.
As of January 1, 2026, CMS-0057-F requires Medicare Advantage, Medicaid, CHIP, and ACA marketplace plans to decide standard prior auth requests within 7 calendar days — down from 14 — and expedited requests within 72 hours. Every denial must now come with a specific, actionable reason.
That matters enormously here. If you catch an expiring auth before the rescheduled visit, you can often get a new one back within a week. Catching it after means chasing a retroactive request, which CMS-0057-F doesn't regulate at all and most payers routinely refuse.
One more thing worth knowing: for Medicare Advantage, an approved authorization is valid for the full course of treatment, and plans can't reopen it mid-course. Some "expired auth" denials on MA claims are simply wrong — and appealable.
HNA tracks every auth with expiry alerts built in. Renewed before expiration. Billed with the correct auth number. Always.
