Why Insurers Issue "Not Medically Necessary" Denials
Obtain your insurer's specific clinical policy bulletin and compare it to published clinical guidelines from specialty societies. Have your treating physician provide a detailed letter of medical necessity citing peer-reviewed evidence and clinical guidelines that directly contradict the insurer's criteria.

Obtain your insurer's specific clinical policy bulletin and compare it to published clinical guidelines from specialty societies. Have your treating physician provide a detailed letter of medical necessity citing peer-reviewed evidence and clinical guidelines that directly contradict the insurer's criteria.

- Clinical guidelines from AHA, NCCN, ADA, APA, or relevant specialty societies support the treatment

- Denial does not reflect current standard of care per treating physician
- Insurer's reviewer may not have the relevant specialty expertise

- Applicable State Insurance Commissioners + CMS regulations on claim handling
- The specific policy language — not just the denial letter summary
- Any state or national mandates that require coverage of the denied service
- ACA guarantees essential health benefits; ERISA governs employer plans
