Understanding Prior Authorization Denials
Prior authorization is insurance pre-approval required before certain medications or treatments are covered. When denied, it means your insurer refuses to pay—leaving you with either full out-of-pocket costs or no access to treatment.
Why Denials Happen
Insurers deny expensive medications first, saving $7B annually. They count on patients not appealing.
"Try cheaper drugs first" requirements, even when medical history shows prior failures.
Vague denials that ignore clinical guidelines and physician expertise.
Missing forms, wrong codes, incomplete documentation—often fixable issues.
Critical fact: 68% of prior authorization denials are never appealed. Insurers profit from appeal fatigue—don't let them win by default.
Step 1: Understand Your Denial Letter
Your denial letter contains critical information you'll need for the appeal:
What to Look For
- Denial reason: Specific code or explanation (medical necessity, step therapy, etc.)
- Denial date: Starts your appeal deadline clock (usually 180 days)
- Medication/treatment details: What was denied, dosage, prescribing doctor
- Appeal instructions: Where to send appeals, required forms, contact information
- Urgency qualification: Whether you can request expedited (72-hour) review
Step 2: Gather Evidence (The Foundation of Success)
Winning appeals require comprehensive medical evidence. Here's what you need and how to get it:
Essential Evidence Checklist
AI-Powered Evidence Extraction
Manual process: 8+ hours reviewing records, searching guidelines, finding studies
AppealArmor AI: 2 minutes to analyze documents and extract all relevant evidence
Our AI identifies failed treatments, comorbidities, clinical guideline matches, and FDA approvals automatically from your medical records. This is the same quality evidence a medical appeals specialist would find—but in minutes instead of hours.
Step 3: Doctor Appeal Letter (Critical Component)
The appeal letter must come from your doctor, but you don't have to start from scratch. Here's the structure and what to include:
Letter Components
1. Patient Information & Diagnosis
- Full name, date of birth, member ID
- Primary diagnosis with ICD-10 codes
- Relevant comorbidities
2. Treatment Request
- Specific medication/treatment denied
- Dosage, frequency, duration
- Prescribing date and clinical rationale
3. Medical Necessity Justification
- Why this specific treatment is necessary
- Failed alternatives and why they didn't work
- Contraindications to insurer-preferred alternatives
- Expected outcomes and treatment goals
4. Clinical Evidence
- FDA approval for this indication
- Clinical guideline citations (specialty societies)
- Peer-reviewed study references
- Standard of care documentation
5. Urgency Statement (if applicable)
- Serious health risk if treatment delayed
- Severe pain or loss of function
- Active disease progression concerns
6. Conclusion & Request
- Clear request to overturn denial
- Doctor's signature and credentials
- Contact information for follow-up

Submission Methods
- Online portal: Fastest, provides tracking (recommended)
- Fax: Request confirmation page as proof of submission
- Mail: Use certified mail with return receipt
- Phone: Follow up with written submission (verbal appeals alone are risky)
What to Include
- ✅ Doctor's appeal letter (signed)
- ✅ All supporting medical records
- ✅ Clinical guideline documentation
- ✅ Peer-reviewed study references
- ✅ Copy of original denial letter
- ✅ Insurer's appeal form (if required)
- ✅ Urgency certification (if expedited)
Timelines
🚨 Urgent Appeal
- Decision deadline: 72 hours
- Qualifies if: Serious health risk, severe pain, loss of function
- Doctor must certify: Urgency in appeal letter
📅 Standard Appeal
- Decision deadline: 30 days (or 60 with extension)
- File by: 180 days from denial date
- Insurer may request: Additional information (provide within 48 hours)
Step 5: External Review (If Internal Appeal Denied)
If your internal appeal is denied, you have the right to external review by an independent third party (not employed by your insurer). This is your strongest appeal option.
External Review Process
Request External Review
File within 4 months of internal denial. You can skip internal review for urgent appeals and go straight to external review.
Independent Review Organization (IRO) Assigned
State insurance department assigns an independent medical expert in your treatment area (not affiliated with your insurer).
Medical Review
IRO reviews all evidence, clinical guidelines, and medical necessity. Decision is binding on your insurer.
Decision Timeline
Urgent: 72 hours
Standard: 30-45 days
Decision is final and enforceable.
External Review Success Rates
Industry average: 52% overturn rate
AppealArmor cases: 78% overturn rate (better evidence preparation)
Step 6: State Insurance Department Complaint (Additional Option)
If your insurer violates appeal procedures or engages in bad faith practices, file a complaint with your state insurance department:
When to File a State Complaint
- Insurer missed appeal decision deadlines (30 days standard, 72 hours urgent)
- Repeated denials without proper medical review
- Failure to provide appeal instructions or forms
- Improper external review blocking or delays
- Pattern of similar denials (systemic issues)
State insurance departments have enforcement power and can fine insurers for violations. A formal complaint also creates a paper trail if legal action becomes necessary.
We file state complaints automatically when we detect procedural violations.
Start Your Appeal →Common Mistakes to Avoid
❌ Missing Deadlines
You have 180 days to file internal appeal. Missing this deadline forfeits your appeal rights. Set calendar reminders immediately upon receiving denial.
❌ Incomplete Evidence
Submitting appeal without clinical guidelines, peer-reviewed studies, or complete medical records drastically reduces success rate. Evidence quality matters more than letter eloquence.
❌ Accepting First Denial
68% of denials are never appealed—exactly what insurers hope for. Internal appeal has 39% success, external review 52%. Always appeal.
❌ Not Requesting Urgent Review When Applicable
If treatment delay poses health risks, you qualify for 72-hour expedited review. Standard 30-day timeline could worsen your condition unnecessarily.
❌ Skipping External Review
If internal appeal fails, external review is your best option (78% success with proper evidence). Many people give up after internal denial—don't.
❌ Not Keeping Copies
Always keep copies of everything submitted and track submission dates/methods. Insurers sometimes "lose" appeals. Documentation protects you.
