What 37252 covers
A catheter-mounted ultrasound probe produces cross-sectional images from inside a noncoronary blood vessel. Vascular surgeons, interventional radiologists, and other endovascular specialists use the images to assess vessel dimensions, plaque, stenosis, or the result of an intervention. The service may be performed in an angiography suite or another setting equipped for endovascular procedures, including during evaluation or treatment of peripheral and visceral vessels.
Report 37252 for the first noncoronary vessel examined by intravascular ultrasound; use 37253 for each additional vessel. The documentation should identify the vessel examined, describe the ultrasound findings, and support that imaging and interpretation were performed. This is an add-on code: report it only with a primary procedure, not as a stand-alone service. CMS treats its payment within the primary procedure’s global-period context.
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.

37252 billing questions
Can 37252 be reported by itself?
No. It is an add-on code and must be reported with a qualifying primary procedure.
When is 37253 used instead?
Use 37252 for the first noncoronary vessel examined and 37253 for each additional vessel. The count is based on vessels, not the number of ultrasound images or pullbacks.
Does 37252 include interpretation?
The service includes intravascular imaging and interpretation. Document the vessel assessed and the findings used in the procedural evaluation.
Can 37252 be reported with angioplasty or stent placement?
It may be reported with a primary vascular procedure when intravascular ultrasound is performed and the code’s requirements are met. The add-on code cannot stand alone.
What documentation supports the code?
Record the noncoronary vessel examined, the use of intravascular ultrasound, and the findings. The record should make clear which vessel is the first vessel for code selection.
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.
