How to appeal a Cigna radiation oncology — proton, sbrt, brachytherapy, imrt, iort denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

Cigna-specific note: Sold its Medicaid Advantage book to HCSC in 2023. Express Scripts (PBM) is Cigna-owned. Frequent class-action litigation around mental health parity.

What Cigna's policy requires for radiation oncology — proton, sbrt, brachytherapy, imrt, iort

Cited policy: Cigna Coverage Policy: Brachytherapy for Prostate, Breast, and GYN Malignancies

LDR prostate brachytherapy covered for low and favorable-intermediate prostate as monotherapy; high-risk prostate as boost combined with EBRT ± ADT. HDR covered as boost or monotherapy in eligible disease; GYN brachytherapy mandatory in definitive cervical cancer.

How Cigna denies radiation oncology — proton, sbrt, brachytherapy, imrt, iort — and how to counter it

Where Cigna pushes back: 1) High-risk patient: LDR boost denied as 'monotherapy preferred'; 2) APBI brachytherapy alleged not medically necessary; 3) Implant procedure CPT bundled inappropriately.

Counter-arguments that hold up: Cite ASCENDE-RT (Morris IJROBP 2017) — LDR brachytherapy boost superior biochemical control vs dose-escalated EBRT for high-risk prostate. Cite ABS Consensus Statements (prostate LDR, prostate HDR, breast APBI, GYN) by name. NCCN endorses brachytherapy boost in unfavorable-intermediate / high-risk prostate. For cervix, omission of brachytherapy is below NCCN standard of care.
