How to Appeal a Prior Authorization Denial: Doctor Tips
To appeal a prior authorization denial, review the payer’s denial notice, identify the reason for the decision, check the filing deadline, gather supporting clinical and administrative records, and submit the appeal through the payer’s required channel.
Some cases do not need a formal appeal. An incomplete request may be corrected and resubmitted. A clinical denial may qualify for peer-to-peer review, reconsideration, an internal appeal, or an expedited review.
The correct path depends on the denial reason, the patient’s health plan, the type of coverage, and the payer’s procedures. Always follow the denial notice and governing plan documents.
Portiva provides administrative support for prior authorization workflows. Clinical decisions remain with licensed healthcare professionals, while coverage decisions remain with the patient’s health plan.

What a prior authorization denial means
A prior authorization denial means the health plan did not approve a requested medication, procedure, test, treatment, device, or other service based on the information and coverage criteria it reviewed.
A denial does not always mean the requested care can never be covered. It may indicate that:
- Required information was missing
- Patient or provider details were incorrect
- The request did not meet a payer rule
- Additional clinical evidence is needed
- A step therapy requirement was not documented
- The requested provider or facility is outside the plan’s network
- The payer determined that its medical necessity criteria were not met
- The service is excluded under the patient’s benefits
Health insurers must explain why certain claims or coverage requests were denied and provide information about disputing the decision. Qualifying cases may proceed through an internal appeal and then an independent external review. Urgent cases may receive faster handling.
The practice should identify the exact reason before preparing a response. A clinical argument will not correct an inaccurate member number, missing attachment, or duplicate submission.
Review the denial notice first
The denial notice should guide every action that follows.
Do not rely only on a portal label such as “denied,” “not certified,” or “not approved.” Obtain and review the full written notice.
Record these details:
- Patient’s full name
- Date of birth
- Member identification number
- Payer and health plan
- Requested service, medication, or procedure
- Ordering and servicing providers
- Authorization reference number
- Date the request was submitted
- Date of the denial
- Exact denial reason
- Payer policy or coverage criterion cited
- Deadline for correction, reconsideration, or appeal
- Required forms
- Accepted submission channel
- Expedited-review instructions
- Payer contact details
- External-review rights, when applicable
The authorization team should save the notice in the appropriate record, assign the case to a named owner, and set a next-action date.
Corrected submission versus formal appeal
A corrected submission fixes an administrative or documentation problem. A formal appeal disputes the payer’s coverage decision.
A corrected submission may fit when:
- The patient’s insurance information was entered incorrectly
- A required form or attachment was omitted
- The wrong provider or facility was selected
- The diagnosis, service, or order information did not match
- The request was sent through the wrong channel
- The payer asked for more information before issuing a final decision
- A duplicate submission caused confusion
- HIPAA Compliant
- US-Based Support
- Trained Healthcare VAs

- The plan specifically instructs the patient or provider to appeal
- Before correcting or resubmitting a request, confirm whether the original appeal deadline remains active.
- A resubmission may not pause or extend that deadline.
Before correcting or resubmitting a request, confirm whether the original appeal deadline remains active. A resubmission may not pause or extend that deadline.

| Treating provider | Supplies the clinical rationale and participates in clinical review |
| Clinical staff | Locates notes, diagnostic results, treatment history, and other supporting records |
| Practice manager | Handles escalations, unresolved workload, and process concerns |
| Patient | Provides required consent or plan information and receives status updates |
| Payer | Reviews the submission and issues the coverage determination |
| External reviewer | Conducts an independent review when the dispute qualifies |
Every case should have:
- A named owner
- A current status
- A filing deadline
- A next action
- A follow-up date
- An escalation trigger
Portiva may assist with administrative coordination, payer follow-up, submission records, and queue tracking. It does not replace clinical judgment or determine coverage.
Assign ownership before gathering records
A strong appeal tells the reviewer where to find the facts that answer the denial reason.
For example, a payer may say that a required medication was not tried. The response should identify:
- The required medication
- Whether the patient received it
- The treatment dates
- The patient’s response
- Any adverse reaction or contraindication
- The supporting clinical record
A medical necessity denial may require the treating clinician to explain:
- The patient’s diagnosis
- Current symptoms or functional limitations
- Relevant examination or test findings
- Previous treatment and its outcome
- Why available alternatives are unsuitable
- The expected benefit of the requested care
- The potential effect of delaying treatment
- The payer criterion being addressed
The phrase “medically necessary” is not enough by itself. The appeal should explain why the requested care is appropriate for this particular patient.
Prepare the appeal letter
A prior authorization appeal letter should identify the patient and request, state what decision is being disputed, present the patient-specific rationale, and list the supporting evidence.
Include patient and plan information
Add:
- Patient’s full name
- Date of birth
- Member identification number
- Health plan
- Requested service or medication
- Ordering provider
- Authorization reference number
- Denial date
State the purpose
Explain whether the submission requests reconsideration, an internal appeal, a coverage exception, or another plan-defined review.
Address the denial reason
Quote the relevant language from the notice or summarize it accurately. Identify the payer policy or criterion when one is cited.
Present the clinical rationale
The treating clinician should explain why the requested care is appropriate for the patient and how the documentation addresses the payer’s concern.
List supporting records
Identify each attachment and explain what it establishes.
Request a specific outcome
State the exact service, treatment, medication, procedure, or device the practice is asking the payer to approve.

Peer-to-peer review versus written appeal
A peer-to-peer review is a clinical discussion. A written appeal creates a formal evidence record.
| Factor | Peer-to-peer review | Written appeal |
|---|---|---|
| Format | Scheduled conversation | Written submission |
| Main participants | Treating clinician and payer reviewer | Patient, representative, practice, clinician, and appeal team |
| Main value | Clarifies medical details or disputed criteria | Formally challenges a denial with supporting records |
| Documentation | Call notes and payer response | Letter, forms, records, and proof of submission |
| Availability | Depends on payer and denial stage | Based on plan appeal rights |
| Deadline | May be brief | Listed in the denial notice |
| Effect on appeal rights | Varies by payer | Begins or continues a formal process |
| Possible result | Approval, continued denial, or request for more information | Written determination |
Before scheduling peer-to-peer review, confirm:
- Whether it is available
- Who may participate
- The scheduling deadline
- Whether the review occurs before or after a final denial
- Whether formal appeal rights remain protected
- Which records the payer reviewed
- Which criteria are being disputed
- Whether the payer will issue a decision during the call
Document the date, participants, discussion, outcome, and any additional records requested.
Frequently Asked Questions:
Can a denied prior authorization be resubmitted?
A denied request may be resubmitted when the payer allows a corrected submission or asks for missing information. Confirm whether resubmission is the correct path and whether the formal appeal deadline remains active.
Is resubmission the same as an appeal?
No. A resubmission generally corrects or completes the original request. An appeal disputes the payer’s decision.
