CPT code 36248 represents selective placement of a catheter into an additional second-order, third-order, or more distal abdominal, pelvic, or lower extremity arterial branch during angiography. This code captures the additional technical and procedural work required when operators selectively catheterize deeper arterial branches beyond an initial targeted vessel. Nationally, angiographic procedures coded with 36248 are relevant for vascular diagnostic workflows and for planning or delivering endovascular therapies in peripheral and visceral arterial territories.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for selective arterial branch catheterization, typical sites of service, and the common modifiers that may accompany procedural reporting. The publication also outlines benchmarking areas such as utilization patterns, relative value considerations, and reimbursement policy topics that affect coverage and coding practice.

This analysis provides clinicians, billing staff, and policy stakeholders with an understanding of when CPT code 36248 is used, why it matters for procedural documentation and billing, and what areas of policy and payer guidance to monitor. Data not available in the input is noted where applicable.
