Your prior authorization was denied — now what?
Published by GLP-1 Coverage Guide · Updated · No clinician review is credited for this page.
Short answer: An initial pharmacy claim rejected because PA is required is an expected step. A later clinical PA denial needs its specific reason checked. CMS allows a prescriber to resubmit corrected, updated or additional information, but there is no appeals process under the Bridge.
Sources for the coverage rules are listed below. An update date marks a revision; it does not imply a sitewide medical review.
First identify what was rejected
Ask whether the pharmacy claim needs prior authorization, the claim was routed to the wrong processor, or the completed clinical PA was denied. These have different next steps. Obtain the exact response and review it with the prescriber; do not assume the problem is a missing diagnosis.
The pharmacy must submit a Bridge claim before the prescriber submits PA. Submitting PA first can cause a patient-not-found error. Bridge claims use BIN 028918 and PCN MEDDGLP1BR. A denial from the regular Part D plan is not a prerequisite.
Review the submitted facts against the denial reason
Your prescriber can check eligible plan enrollment, the indication, covered formulation, BMI at therapy initiation, qualifying diagnoses and Part D-paid GLP-1 use in 2026. If you have lost weight on therapy, the starting BMI matters; replacing it with today’s weight can misstate the criteria.
If a Part D-covered indication applies, the request should go through the drug plan under that indication. That plan has its own formulary, authorization requirements and costs. This guide cannot guarantee coverage or a successful resubmission.
Corrected resubmission is different from an appeal
CMS permits the prescriber to resubmit if the original form contained incorrect information or new or additional information is available. The Bridge has no appeals process. CMS describes PA decisions within 72 hours of submission; ask the office when it sent the request and whether it received a response.
For a denial by your regular Part D plan, use the plan’s coverage determination and appeal instructions instead. Keep the two processes separate.

Common questions
Can I appeal a Bridge denial?
CMS says there is no Bridge appeals process. Your prescriber may resubmit corrected, updated or additional information for re-review.
Does a rejected first pharmacy claim mean I do not qualify?
Not necessarily. An initial claim requesting PA is an expected step. Ask the pharmacist for the actual response before interpreting it as a clinical denial.
Which BMI should be documented?
BMI at GLP-1 therapy initiation, including therapy started before Medicare or July 2026. Ask the prescriber for the starting records.
