Prior authorization renewal: expiration dates and treatment limits
Prior authorizations can expire by date or reach their treatment limits first. Renewal depends on the original approval, the patient's treatment history, and the current plan.
Prior authorizations often have an end date, a quantity limit, or both. The payer's determination controls. A service outside those terms may need an extension or a new approval even when the authorization number remains in the chart.
Expiration limits what the approval authorizes; it does not end the patient's insurance. Whether a service remains covered depends on its date, the approved quantity, and any continuation protections.
Track two independent limits
| Limit | What can go wrong | What to track |
|---|---|---|
| Date window | Missed visits push treatment past the end date | Start date, end date, and scheduled service dates |
| Authorized quantity | Units run out before the window closes | Allowed and consumed units per code |
| Unit definition | A milligram balance is mistaken for a visit count | The code's unit: mg, device, session, service, or bundle |
A missing end date needs investigation. Confirm whether the approval has no date limit or whether capture missed it. Keep the letter, portal result, or electronic determination that answers the question.
Match the request to the treatment history
These are useful operational categories. Payer forms may use different names. The point is to send evidence that matches what actually happened.
| Situation | Evidence to gather |
|---|---|
| Initial treatment | Diagnosis, requested treatment, and required prior trials |
| Continuing on the same plan | The existing approval and response to treatment |
| Continuing after a plan change | Treatment history and the new plan's transition rules |
| Inheriting an outside approval | The original determination and supporting records |
| Restarting after a gap | Why treatment stopped and the policy for restarting |
A plan change does not always require immediate reauthorization. Medicare Advantage coordinated care plans must provide at least a 90-day transition period for an active course of treatment when an enrollee switches to a new plan. CMS transition protections should be checked before interrupting that course.
Build the next request while treatment is underway
Keep baseline and follow-up measurements on the same record. Weight-management renewal may require change from pretreatment weight. TMS continuation may require change on a depression scale. Use the current policy's measure and threshold, rather than a standard percentage copied across payers.
- 01Capture the determinationRecord dates, quantity, unit definition, source, and responsible staff member.
- 02Collect response evidenceSchedule any assessment needed for the next request before the current approval ends.
- 03Submit and follow upAllow for preparation, payer review, and a correction cycle; assign follow-up dates.
- 04Reconcile the decisionRecord the new terms and verify that the next planned service falls within them.
Recheck coverage after a plan change and review the authorization after a change in product, dose, provider, or site of care. These events can change its applicability. A general eligibility response will not reliably answer every one of those questions.
Use the deadline for the benefit you are working
CMS-0057-F introduced seven-calendar-day standard and 72-hour expedited decision requirements for specified non-drug requests beginning in 2026. The rule excludes drugs, and those timeframes do not apply to federally facilitated marketplace QHP issuers under that rule. CMS's final-rule summary sets out the scope.
A payer's decision deadline is only one part of the lead time. The clinic still needs time to obtain records, complete the request, and resolve missing information. Set reminders around the actual workflow and confirm the payer's submission window.
How Foresight helps
Foresight stores authorization dates with a confirmed, missing, or invalid quality status and keeps authorized units separate by code and unit definition. Staff can distinguish an expired window from an exhausted quantity and trace the underlying determination.
For weight-management requests, Foresight classifies the treatment relationship from available evidence, including an existing approval, a new plan, or a restart. Renewal reminders use configurable lead times, with separate pharmacy and medical settings and payer-specific timing where configured. Repeated reminders keep the follow-up visible until someone acts.
The TMS billing guide shows how these controls work across a course of sessions.
01Do all authorizations expire on December 31?
No. Read the determination. A plan-year change is a reason to verify benefits and current requirements, not a universal expiration date.
02Can we use remaining units after the end date?
Do not assume so. Confirm an extension, new approval, or applicable continuation protection before treating those units as authorized.
