CPT code 61623 denotes temporary balloon occlusion (TBO) of neck arteries used as an adjunct to another vascular or neurovascular procedure, such as aneurysm repair. Nationally, the code captures targeted, time-limited endovascular control of arterial flow to reduce bleeding risk or prevent embolic complications during complex intracranial or extracranial interventions. Its appropriate use affects care coordination, intraoperative risk management, and billing for adjunctive endovascular techniques.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent, common sites of service, and how this adjunctive procedure is classified for billing purposes. The publication outlines benchmark considerations for payer coverage patterns, typical clinical contexts where TBO is applied, and relevant billing guidance implications. It also highlights common modifiers and service-line considerations for reporting adjunctive endovascular maneuvers when present. Data not available in the input is noted where applicable.

This summary equips clinicians, coding staff, and payers with a focused reference on CPT code 61623 — what it represents, where it is typically performed, and why accurate coding matters for perioperative management and claims processing.
