Transpupillary Thermal Therapy

Aetna considers transpupillary thermotherapy medically necessary only for retinoblastoma affecting <50% of the retina without vitreal or subretinal seeds and for small (2–3 mm) posterior choroidal melanomas (ICD‑10 C69.20–C69.32) when these selection criteria are met; all other indications—including central serous chorioretinopathy, indeterminate choroidal melanocytic lesions, choroidal metastases, and AMD‑related choroidal neovascularization—are experimental/investigational and excluded.

"ICD-10 codes covered if selection criteria are met: C69."
