APPEAL FRAMEWORK
SECTION 2
EXHIBIT B: Why Lumbar Laminectomy Is Commonly Denied
Insurance companies deny this procedure for the same reasons they deny most surgical procedures:
- Insufficient Medical Necessity Documentation (35-40%) — Payer claims your doctor didn't prove the procedure was necessary
- Conservative Treatment Not Documented (25-30%) — Payer claims you didn't try less invasive alternatives first
- Prior Authorization Issues (15-20%) — Auth not obtained, expired, or system error
- Clinical Criteria Not Met (10-15%) — Payer's internal criteria for medical necessity not satisfied
EXHIBIT C: Critical Documentation for This Appeal
To win your appeal, you'll need:
- All imaging studies (X-rays, MRI, CT scans) showing the problem
- Detailed documentation of any conservative treatment attempts (PT, injections, medications)
- Your doctor's clinical notes explaining why surgery was necessary
- Functional limitation assessment (how the condition limits your daily activities)
- Any relevant test results or measurements
- Prior authorization letter (if one was obtained)
