CPT 00350: Anesthesia for Major Vessels of the Neck, Unspecified
CPT code 00350 designates anesthesia services for procedures on the major vessels of the neck that are not otherwise specified.

Major carriers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare.
Readers will find a concise overview of the clinical context for 00350, common diagnostic scenarios that map to neck vessel interventions, and the coding relationships that affect anesthesia reporting for these procedures. The publication summarizes payer coverage considerations, typical sites of service, and related anesthesia procedure codes to help delineate service scope. It also highlights where coding specificity matters for claim adjudication and when related codes may be used for simpler or more complex neck vessel anesthesia services. Data not available in the input are explicitly noted where applicable.
