Answer
How long does GLP-1 prior authorization take?
The short answer
The clock depends on your coverage and request. For Part D benefits, CMS describes 72-hour standard and 24-hour expedited decisions; an exception clock starts when the prescriber’s supporting statement arrives.
Ask which review is actually underway
Before counting days, establish whether the plan has a benefits request, an exception, a payment request or an appeal. Ask when it received the request and which rule sets the response deadline. A clinic’s sent timestamp and the plan’s received timestamp can be different.
This article separates the Part D decision clocks from practical follow-up questions for other coverage. A Medicare time limit should not be borrowed for an employer or Marketplace plan merely because the same drug is involved.
Part D benefits requests have standard and expedited clocks
CMS describes a standard benefits determination within 72 hours and an expedited benefits determination within 24 hours after receipt. For an exception, the clock begins when the required prescriber statement is received.
Ask the clinic whether that statement was included and the plan whether it was received. Repeatedly resending an incomplete form can leave the actual evidence gap unresolved. Keep the request number and a copy of what was sent.
Payment for a completed fill has a different deadline
CMS states that payment requests, including those involving an exception, receive a written decision and payment when appropriate within 14 calendar days after receipt. An urgent upcoming prescription and reimbursement for medication already bought therefore should not be treated as the same review.
Tell the plan which outcome you are seeking. If there are two requests, keep separate reference numbers and dates. A benefits decision does not automatically settle the completed-fill payment question.
Expedited review needs clinical support
Medicare ties expedited handling to a risk to life, health or the ability to regain maximum function from waiting for the standard process. Ask the prescriber to explain the clinical urgency when that standard applies. An approaching refill is important to disclose, but it does not by itself establish every program’s urgent-review eligibility.
If expedited handling is refused or the response is overdue, ask which review or grievance route applies. CMS distinguishes operational complaints from disagreement with a coverage decision. Use the relevant process rather than assuming one complaint does both jobs.
For other coverage, collect the rule and receipt evidence
Ask for your plan’s response deadline, how it treats missing information and whether an extension applies. Record the names, dates and instructions. Obtain the formal denial if the request is refused so you can see the reason and appeal route.
Keep the clinical team informed while the financial process continues. The prescriber and pharmacist can discuss treatment continuity; this page cannot decide an individual substitute, dose change or refill schedule.
