The short answer
Ask the pharmacy for the exact rejection message, then contact your plan to identify what needs to happen next. A billing error, prior authorization, refill timing issue, and excluded drug require different responses. Tell your pharmacist and prescriber promptly if you may run out before the issue is resolved.
Start with the rejection reason, not a new price search
Write down the medication, strength, form, quantity, pharmacy, and date of the attempted fill. Ask whether the claim was rejected or accepted with a higher patient charge. A large copay is a different problem from a claim the plan would not process.
Have the pharmacy check that it used your current insurance information. Ask for the rejection wording or code and which phone number to call. Keep insurance identifiers and prescription records in a private note rather than a public comment or email to RxCompare.
Was this claim rejected, or is this the amount due on a covered claim? What exact message did the plan return, and is there anything you can correct or clarify before I call the insurer?
Match the problem to the next question
Use this checklist to organize the call. The plan must explain its own requirements; these questions do not determine whether you qualify for coverage.
- Member or billing information: does the plan have active coverage for this fill date, and does the pharmacy have the right details?
- Prior authorization: what information is missing, who must submit it, and where should it go?
- Drug not covered: is the exact product excluded, and is a coverage exception available?
- Quantity or refill timing: which limit triggered the rejection, and what review process applies?
- Pharmacy restriction: is a particular network, mail-order, or specialty pharmacy required?
- A previous fill is still showing: should the pharmacies investigate an earlier uncollected or transferred claim?
Ask about prior authorization, exceptions, and appeals
Medicare drug plans can use prior authorization, step therapy, and quantity limits. Prior authorization is a coverage approval requirement; it is not the same as your prescriber issuing a prescription. Medicare describes exception requests supported by the prescriber when a coverage rule is not appropriate for the patient.
For Marketplace plans, HealthCare.gov describes a drug-exception process and the right to appeal a denied request. Ask your own plan for the applicable form, evidence, submission route, and deadline. Employer coverage, Medicaid, and other plans can have different procedures.
Ask the prescriber’s office who is handling the request and how you will receive updates. Keep the case number, submission date, and next follow-up date together. If timing could affect your health, ask the prescriber and plan whether an expedited review is appropriate.

Make a supply plan while the decision is pending
Tell the pharmacist and prescriber how much medication you have left and when you expect to run out. Ask what they recommend while coverage is unresolved. Do not stretch doses, stop treatment, or switch products on your own to fit an insurance timeline.
Ask the plan whether any temporary coverage applies to your situation and get its terms before relying on it. Ask who will call whom next: a pending request is easier to follow when someone owns the next step. If symptoms are severe or you think you are having a medical emergency, seek urgent medical help.
Compare a cash option without assuming reimbursement
You can request the pharmacy’s full cash quote and any eligible discount quote for the exact prescribed fill. Ask about availability and fees as well as price. Before paying, ask your plan whether an outside-plan purchase can be submitted for reimbursement or benefit credit and what records it would require. Do not budget on getting that money back without confirmation.
If the cost is unaffordable, ask the prescriber’s office about assistance applications. Compare program eligibility separately from the insurance decision. RxCompare’s NADAC figures describe pharmacy acquisition costs and cannot predict a cash price or the result of an appeal.
Before ending the insurer call
- Record the representative’s name, date, and case or reference number.
- Repeat the exact next action and who must take it.
- Ask when to follow up and how to check that documents arrived.
- Request the written decision and appeal instructions if coverage is denied.
- Share the outcome with your pharmacy and prescriber through their official channels.
Please explain the reason for this decision and the next step for my specific plan. What does my prescriber need to submit, when is it due, and what should we do if I will run out before a decision?
Common questions
Does prior authorization mean my doctor must send another prescription?
Not necessarily. A prescription authorizes dispensing; prior authorization concerns the plan’s coverage requirements. Ask which information the plan needs and whether your prescriber must submit a separate request.
Will changing pharmacies fix a rejected prescription?
Ask what caused the rejection first. A pharmacy-network problem may call for another location, while a coverage requirement may follow the prescription. Confirm the destination pharmacy and next step with your plan.
If I pay cash now, will insurance repay me later?
Do not assume it will. Ask your plan about reimbursement, deadlines, required receipts, and deductible or out-of-pocket credit before paying. Keep its answer with your receipt.
