Why was my prior authorization denied? Top reasons and how to fix each
Most prior authorization denials are not about whether care is needed. They are about whether the submission proved it against the payer’s written criteria. Here are the most common reasons and how to fix each.
The most common denial reasons
- Insufficient clinical documentation. The note does not contain the specific findings the payer policy requires. Fix: map the note to each criterion in the policy and add the missing findings (exam, imaging, severity, function) before resubmitting.
- Conservative care not documented. The policy requires a duration of conservative treatment (for example physical therapy, medication, injections) that is not shown. Fix: document the type, dates, and outcome of prior conservative care, or explain why it was not appropriate.
- Medical-necessity criteria not met or not cited. The request did not reference the payer’s own policy. Fix: cite the exact policy and address each criterion directly, in the payer’s language.
- Coding mismatch. The diagnosis and procedure codes do not align, or the diagnosis does not support the procedure. Fix: confirm the codes match the documentation and the payer’s covered indications.
- Missing prior studies. Required imaging or labs were not included. Fix: attach the relevant reports and reference them in the request.
- Step therapy or quantity limits. A required earlier therapy or a visit/unit limit was not satisfied. Fix: document the step-therapy history or request an exception with rationale.
- Administrative errors. Wrong form, wrong portal, missed deadline, or eligibility lapse. Fix: verify eligibility, the correct submission channel, and timely-filing windows before submitting.
How to turn a denial around
Read the denial reason carefully, find the exact policy criterion it references, and respond to that criterion specifically with documentation and evidence. A focused, policy-cited response is far more effective than a general letter. Praxigen flags missing documentation against the payer’s criteria before you submit, and drafts a policy-cited appeal if a case is denied. You review and submit; nothing is sent automatically.
Frequently asked questions
What is the most common reason prior authorizations are denied?
Insufficient or unmatched clinical documentation: the note does not contain the specific findings the payer’s policy requires, or it is not mapped to the policy criteria. Most denials are documentation and matching problems, not care-need problems.
Can a denied prior authorization be appealed?
Yes. Most denials can be appealed, and a focused appeal that cites the payer’s own policy criteria and addresses the stated denial reason directly is more effective than a general letter. Check the denial notice for the appeal deadline.
How do I fix a medical-necessity denial?
Find the exact criterion in the payer policy that was not met, then provide the specific documentation (findings, conservative care, prior studies) that satisfies it, citing the policy in the payer’s own language.
