What 37237 covers

This add-on captures stent placement in an additional qualifying artery during an open or catheter-based intervention. It applies to arterial sites in the 37236 code family, such as renal or mesenteric arteries; cervical carotid, coronary, pulmonary, lower-extremity, intracranial, and dialysis-circuit stenting follow other code pathways. Interventional radiologists, vascular surgeons, and other physicians performing vascular procedures may place the stent in a hospital or office-based setting.

Report 37237 for each additional artery after reporting 37236 for the initial artery. Count distinct treated arteries, not additional stents or lesions within one artery. The operative report should identify the treated artery and document the approach and stent placement. CMS classifies 37237 as an add-on code: bill it only with a primary procedure, and its payment falls within that procedure’s global period.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

37237 billing questions

When should 37237 be used instead of 37236?

Use 37236 for the initial qualifying artery treated and 37237 for each additional qualifying artery treated in the session.

Does another stent in the same artery support 37237?

No. The add-on is based on an additional artery, not the number of stents or lesions treated within one artery.

Can 37237 be billed by itself?

No. It is an add-on code and must be reported with a primary procedure, typically 37236 for the initial artery.

What documentation supports an additional unit?

Document each distinct additional artery treated and the stent placement performed in that artery. The operative report should make clear which artery was the initial vessel and which were additional.

Does 37237 have a separate global period?

CMS states that the add-on is paid within the primary procedure’s global period.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
