Radiation Therapy Insurance Denial Appeal Guide
Radiation therapy denials often involve disputes about the type of radiation (proton vs photon), treatment facility, or number of fractions prescribed.
Why Radiation Therapy Gets Denied
Radiation therapy is generally covered for cancer treatment, but denials occur around the specific type of radiation, facility choice, and treatment plan details. Proton beam therapy is a particular flashpoint.
Common Denial Reasons
- Proton therapy denied (photon therapy preferred as equivalent)
- Treatment facility not in network
- Number of fractions exceeds insurer's guidelines
- Re-irradiation denied
- Prior authorization for treatment plan not obtained
How to Appeal
- For proton therapy — cite clinical scenarios where proton reduces normal tissue exposure (pediatric cancers, base of skull tumors, re-irradiation)
- Reference NCCN guidelines for your specific cancer type and stage
- Radiation oncologist letter — explaining the rationale for the specific treatment plan
- If facility is the issue — document why the specific facility is needed (specialized equipment, clinical expertise)
- Request expedited review — cancer treatment should not be delayed
Proton vs Photon
While many cancers can be treated equally well with either proton or photon therapy, specific clinical scenarios clearly favor proton therapy. The strongest appeal cases involve pediatric patients, tumors near critical structures, or re-irradiation situations.
