What 37247 covers
This add-on represents balloon dilation of a second or subsequent eligible artery, such as a renal, mesenteric, or upper-extremity artery, to improve blood flow through a narrowed segment. It is used for open or endovascular treatment outside the code families for coronary, intracranial, and lower-extremity occlusive-disease interventions. Vascular surgeons and interventional radiologists commonly perform these procedures in operating rooms or endovascular suites.
Report 37247 with 37246 for the first treated artery; it is not a stand-alone service. The record should identify each artery treated, the lesion and clinical indication, and the angioplasty performed in the additional artery. Necessary imaging guidance and radiological supervision and interpretation are included in the angioplasty service. CMS treats this as an add-on paid within the primary procedure’s global period. When the service is bilateral and reported with modifier 50, CMS pays 150% of the applicable amount.

37247 billing questions
When should 37247 be used instead of 37246?
Use 37246 for the first eligible artery treated with balloon angioplasty. Use 37247 for each additional eligible artery treated in the same session.
Can 37247 be reported by itself?
No. It is an add-on code reported with the primary arterial angioplasty code 37246.
Can imaging guidance be billed separately?
Necessary imaging guidance and radiological supervision and interpretation are included in the angioplasty service.
What documentation supports reporting an additional unit?
Document the additional artery and its treated lesion, the reason for intervention, and the balloon angioplasty performed there. The record should distinguish it from the artery represented by 37246.
How is bilateral treatment handled under the CMS payment rule?
For a bilateral procedure reported with modifier 50, CMS pays 150% of the applicable amount.
How does 37247 relate to the primary procedure's global period?
CMS identifies 37247 as an add-on paid within the global period of the primary procedure. Report it with the primary angioplasty service rather than as a separate stand-alone procedure.
