ACL Reconstruction Insurance Denial Appeal Guide

ACL reconstruction is one of the most common orthopedic surgeries, yet insurers may deny it citing insufficient conservative treatment documentation or questioning medical necessity.

Why ACL Reconstruction Gets Denied

Insurance companies may deny ACL reconstruction when they feel conservative treatment hasn't been adequately attempted, or when the clinical documentation doesn't clearly demonstrate instability and functional limitation.

Common Denial Reasons

  • Conservative treatment not documented (PT, bracing, activity modification)
  • MRI findings don't show complete tear
  • Functional instability not adequately documented
  • Pre-authorization not obtained
  • Age or activity level questioned

How to Appeal

  1. Document functional instability — giving way episodes, inability to return to work/sport
  2. Lachman test and pivot shift — positive physical exam findings documented by orthopedic surgeon
  3. MRI confirming ACL tear — complete vs partial tear matters for approval
  4. Failed conservative treatment — 4-6 weeks of PT documentation
  5. Orthopedic surgeon letter — explaining risk of meniscal and cartilage damage without surgery

Key Appeal Points

Untreated ACL tears lead to progressive meniscal tears and early osteoarthritis. This long-term cost argument is compelling to insurers who are focused on cost containment.
