37246 – Transluminal balloon angioplasty (except lower extremity artery[ies] for occlusive disease, intracranial, coronary, pulmonary, or dialysis circuit), open or percutaneous, including all imaging and radiological supervision and interpretation necessary to perform the angioplasty within the same artery; initial artery
+37247 – each additional artery (List separately in addition to code for primary procedure)
37248 – Transluminal balloon angioplasty (except dialysis circuit), open or percutaneous, including all imaging and radiological supervision and interpretation necessary to perform the angioplasty within the same vein; initial vein
+37249 – each additional vein (List separately in addition to code for primary procedure)
Report a single code for each vessel treated. Report only one intervention if a lesion extends across the margins of one vessel into another, but can be treated with a single therapy. Report only the stent code in a single vessel if both angioplasty and stenting are used, even if the lesions are separate.
Report separately:
- Catheterization
- Diagnostic angiography
- Ultrasound guidance for access
- IVUS
- Thrombolysis and/or mechanical thrombectomy
- Extensive repair or replacement of an artery
These codes are not used when there are specific codes for angioplasty on that location (e.g., lower extremity arteries).
