Quick Answer
If your prior authorization was denied, start by reading the notice, finding the reason, and asking your provider what documentation may help. Prior authorization is a health plan approval step that may be required before a service or prescription is covered, but the denial is not always the final step. You may be able to appeal, ask about peer-to-peer review, or request faster review if the situation is urgent.
Prepare Prior Auth Appeal
Organize your denial reason, provider questions, and next steps.
If this is your situation, start here
- “The notice says more information is needed”: Ask your provider what documents can be sent.
- “The request was denied as not medically necessary”: Ask whether provider notes or peer-to-peer review may help.
- “The service is urgent”: Ask about faster review options.
- “I am not sure who should appeal”: Ask whether you or your provider must submit the next step.
What does prior authorization mean?
Prior authorization is approval from a health plan that may be needed before a service or prescription is covered. It may also be called preauthorization, prior approval, or precertification.
Preauthorization is not a promise the plan will cover the cost. The plan's rules and the wording in your notice matter, so read your notice carefully for what applies to you.
What this means for you
A prior authorization denial is a step in the process, not a final coverage decision. Your notice should say what is missing and what your options are, including help from your provider.
Why was my prior authorization denied?
The denial reason matters because it tells you what to ask your provider or insurer for next.
More clinical information needed
The notice may say the insurer needs more clinical details before it can decide. Ask your provider if they can supply additional notes or documentation.
Not medically necessary
The notice may say the insurer did not consider the request medically necessary under your plan's rules. Ask your provider whether they can supply more information explaining the request.
Step therapy required
Some plans require trying a different treatment or medication first. The notice should explain whether this applies and what the plan's step therapy rules require.
Formulary or medication issue
For prescription requests, the notice may say the medication is not on the plan's formulary or requires a different approval path. Ask your insurer what alternatives or next steps exist.
Plan exclusion
Some services or treatments are excluded under a specific plan's terms. Look at your plan document or summary of benefits, then ask your insurer what the exclusion means and write down the answer.
Out-of-network or location issue
The notice may say the request involves an out-of-network provider or facility. Ask your insurer whether this affects the request and what your options are.
Missing or incorrect information
The notice may say the request was incomplete or contained an error. Ask your provider's office if they can correct and resubmit it.
What should I do first after a prior authorization denial?
- 1Read the denial notice carefully.
- 2Find the denial reason.
- 3Check the deadline and appeal instructions.
- 4Ask the insurer what information is missing.
- 5Contact your provider's office.
- 6Ask whether peer-to-peer review is available.
- 7Keep copies of everything.
HealthCare.gov says plans must explain denials in writing. Use the wording in the notice as your starting point for the reason and next steps.
Simple way to ask
Try saying: “My prior authorization was denied. Can you tell me what information was missing, whether my provider can submit more documentation, and whether peer-to-peer review is available?”
How can my provider help?
Your provider's office may be able to:
- Submit additional documentation.
- Clarify the diagnosis, treatment history, or reason for the request.
- Let you know whether a peer-to-peer review is available.
- Submit appeal materials directly, depending on plan rules.
What is peer-to-peer review?
Peer-to-peer review is a conversation between your provider and a plan reviewer that may be used to discuss the request. It does not guarantee approval.
Ask your provider and insurer whether peer-to-peer review is available for your situation and how to request it.
How do I appeal a prior authorization denial?
- 1Confirm who must submit the appeal.
- 2Use the denial reason as the focus.
- 3Gather supporting documents.
- 4Ask for provider support if relevant.
- 5Submit using the required method.
- 6Ask for the decision in writing.
- 7Keep a copy.
How long does insurance have to respond?
Timing depends on the request, plan, and situation. HealthCare.gov says plans must notify users within 15 days if seeking prior authorization for treatment, 30 days for medical services already received, and 72 hours for urgent care cases.
Internal appeal timing is separate. HealthCare.gov says many internal appeals must be filed within 180 days. Urgent situations may have faster review options.
Call the number on your denial notice and ask what timing applies to you, then write down the answer.

Frequently asked questions
What does prior authorization denied mean?
It means the health plan did not approve the request as submitted. The notice should explain the reason and what appeal or next-step options are available.
Can I appeal a prior authorization denial?
In many situations, yes. Check your denial notice for the appeal instructions, deadline, and who should submit the appeal.
Should my doctor help with a prior authorization denial?
Your provider may be able to help by submitting notes, clarifying the treatment request, or asking about peer-to-peer review. Ask your provider's office what they can provide.
Is prior authorization the same as coverage approval?
Not exactly. HealthCare.gov says preauthorization is not a promise your plan will cover the cost. Check your plan rules and notice for what applies.
Can I get the treatment while my appeal is still pending?
Generally not through your regular coverage, since prior authorization denials usually mean the plan will not pay until the request is approved or overturned. If the situation is urgent, ask your insurer about expedited or urgent appeal review, which has faster decision timeframes.
How is this different from a medical necessity denial?
A prior authorization denial means the plan did not approve the request before treatment happened. A medical necessity denial is about whether the plan's clinical criteria were met, and can happen either before or after treatment. The two often overlap. See our medical necessity denial guide for that side of it.
Can PapaShield submit the prior authorization appeal for me?
No. PapaShield can help you organize appeal preparation and draft materials, but you or your provider submit them using your plan's instructions.
