Summary
Laser Interstitial Thermal Therapy (LITT) for neurological conditions is considered investigational and not covered for all indications including brain tumors, radiation necrosis, and drug-resistant epilepsy. This policy was reviewed on 02/24/2025 with no changes to the investigational status.
Action Required
Immediately: Billing team must ensure all LITT procedures (CPT 61736, 61737 and ICD-10 procedure codes 00500Z3, 00503Z3, 00504Z3) are flagged as investigational/non-covered in billing system. Verify prior authorization processes capture investigational status. Claims for these procedures will likely be denied as investigational unless FEP coverage exception applies.
