CPT code 0075T represents an endovascular procedure to place a stent in an extracranial vertebral artery to treat stenosis or blockage; it also includes the imaging, radiological supervision, and interpretation needed to determine and support the intervention. This procedure is clinically important for patients at risk of posterior circulation ischemia and has implications for hospital-based vascular and interventional radiology services nationwide. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of clinical context and service settings, summaries of payer coverage patterns where available, and benchmarking and policy-related considerations relevant to reimbursement and utilization. The publication covers how this service is typically delivered (hospital outpatient or inpatient interventional suite), what the code bundles (procedure plus imaging and interpretation), and implications for billing and clinical documentation. Data not available in the input will be noted explicitly in sections that require payer-specific rates, taxonomies, diagnosis pairings, or utilization metrics.
