What 37236 covers

37236 covers open or catheter-based placement of an intravascular stent in an artery, outside the separately coded lower-extremity, cervical carotid, and intracranial services. Interventional radiologists, vascular surgeons, and other physicians performing vascular interventions may use it for sites such as renal, mesenteric, or subclavian arteries. The service includes imaging supervision and interpretation for the stent procedure, as well as balloon angioplasty performed in the same vessel.

Report 37236 for the first treated artery in this code family; use 37237 for each additional treated artery. Documentation should identify the treated artery, the stent placement, and any angioplasty performed in that vessel. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

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.

37236 billing questions

When should 37236 be used instead of 37238?

37236 is for an artery; 37238 is the corresponding initial-vessel code for a vein. Select based on the treated vessel, not the access route.

How is another treated artery reported?

Use add-on code 37237 for each additional artery treated in the same session. Multiple stents in one artery do not, by themselves, make it an additional artery.

Is angioplasty in the stented artery separately reported?

Angioplasty performed in the same vessel is included in 37236. The code also includes imaging supervision and interpretation for the stent procedure.

Can modifier 50 be used for bilateral arterial stenting?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

What payment rules apply when other procedures are performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are reduced. The 0-day global period includes same-day preoperative and postoperative care.

When is an assistant at surgery payable?

Assistant-at-surgery payment is available only when documentation supports medical necessity. Co-surgeon and team-surgery payment are not permitted.

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.
