CPT code 35013 denotes open vascular surgical repair of a ruptured axillary–brachial artery aneurysm with treatment of concurrent occlusive disease, using direct arterial repair or graft placement. This procedure is clinically significant nationwide because ruptured upper-extremity arterial aneurysms are urgent vascular events that require prompt surgical intervention to prevent hemorrhage, limb ischemia, or long-term functional loss. Billing and coding clarity for this service affects hospital surgical revenue, payer authorization, and case-level classification for quality measurement.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent and typical sites of service, plus benchmarks and policy-relevant considerations where available. The publication highlights coding context, common modifier usage (listed separately), and areas where payer policies often vary, such as inpatient versus outpatient setting determinations and graft material coverage. The content supports clinicians, coders, and policy analysts by summarizing the procedure's clinical scope, listing primary payers, and identifying where additional documentation or payer-specific policy review may be required. Data not available in the input is noted where applicable.
