CPT code 37246 denotes percutaneous transluminal balloon angioplasty of an artery performed via open incision or percutaneous access, with inclusion of all imaging guidance and radiological supervision and interpretation. The code excludes procedures on the dialysis circuit, lower extremity, intracranial, coronary, and pulmonary arteries. This code is nationally relevant because angioplasty remains a common, image-guided treatment for arterial stenosis and occlusion across hospital inpatient and outpatient settings, with implications for payer coverage, prior authorization workflows, and clinical care pathways. Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise overview of the clinical service represented by CPT code 37246, common sites of service, and the procedural scope as defined by the CPT descriptor. The publication summarizes payer coverage considerations and benchmarking context, highlights coding and billing boundaries (noting explicit arterial territories excluded by the descriptor), and provides operational context for radiology, vascular surgery, and interventional cardiology stakeholders. Data limitations: Associated taxonomies, specific ICD-10 diagnosis links, and related codes are not provided in the input and are noted as unavailable where applicable.
