CPT code 37248: Venous angioplasty, initial vein2026 Medicare rate & RVUs

Medicare pays $1,305.31 for 37248 nationally in the office and $260.19 in a hospital or facility. Local office rates run $1,138.12–$1,789.24.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 37248 covers

This service opens a narrowed or obstructed vein by advancing and inflating a balloon across the lesion. It may be performed percutaneously or through an open approach by an interventional radiologist, vascular surgeon, or other physician performing venous intervention. Common settings include treatment of iliac or central venous stenosis related to prior thrombosis, compression, or catheter-related injury. The code includes the imaging guidance and radiological supervision and interpretation needed for the angioplasty; it is not for angioplasty of a dialysis circuit.

Report 37248 for the initial vein treated during the session. Use 37249 for each additional vein treated, rather than counting balloon inflations or lesions. The operative report should identify the vein, stenosis, and angioplasty performed. When a stent is placed in the same vein, the stent code includes angioplasty in that vessel. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. In a session with multiple procedures, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
