Summary
Aetna updated its thoracoscopic sympathectomy policy (CPB 0310) to specify medical necessity criteria for 8 specific conditions including causalgia, CPVT, Long QT syndrome, Raynaud's disease, VT/VF storm, vascular occlusive disease, visceral pain, and intractable hyperhidrosis. The policy explicitly designates certain indications (acne, plantar hyperhidrosis, facial blushing, heart failure) as experimental, investigational, or cosmetic and therefore non-covered. Billing teams must verify medical necessity documentation against these criteria before claim submission.
Action Required
By 2026-05-20: Billing team must implement claim verification procedures for CPT 32664 (thoracoscopic sympathectomy). Before processing claims, verify: (1) diagnosis matches one of the 8 covered conditions (causalgia, CPVT, Long QT syndrome, Raynaud's disease, shoulder-hand syndrome, visceral pain, VT/VF storm, or vascular occlusive disease); (2) for hyperhidrosis claims, confirm all pre-requisites are met (iontophoresis/botulinum toxin failure, significant life disruption, antiperspirant failure, and pharmacotherapy failure if episodic); (3) reject or route for denial any claims with excluded diagnoses including acne vulgaris (L70.0), plantar hyperhidrosis (L74.511, L74.513), facial blushing (R23.2), or heart failure (I50.1-I50.9). Update billing software to flag these non-covered ICD-10 codes. Add prior authorization requirement checklist to encounter forms. Providers must document failure of prerequisite therapies for hyperhidrosis cases. Claims submitted without proper medical necessity documentation or with excluded diagnoses will be denied.
