What 37253 covers

A vascular specialist advances an ultrasound catheter through the vessel to examine the lumen and wall from inside. Intravascular ultrasound can help assess plaque, narrowing, thrombus, or the result of an intervention in noncoronary vessels such as the aorta, iliac vessels, and peripheral arteries or veins. Vascular surgeons, interventional radiologists, and other physicians performing endovascular procedures commonly use it in an angiography suite or operating room. The service includes image interpretation.

Report 37253 for each additional noncoronary vessel examined after the initial vessel, which is reported with 37252. Count vessels, not ultrasound passes, images, or separate findings within one vessel. The record should identify each vessel evaluated and support the physician’s interpretation and clinical use of the images. This is an add-on code: submit it with an eligible primary procedure, not by itself. Its payment is within that primary procedure’s global period; it does not establish a separate global period.

92979 is for an additional coronary vessel. Use 37253 for an additional noncoronary vessel.
37246Arterial angioplastyInitial artery
37246 reports balloon angioplasty in an artery, not ultrasound imaging. It may be reported with IVUS when both services are performed.

37253 billing questions

How does 37253 differ from 37252?

37252 represents intravascular ultrasound of the initial noncoronary vessel. Use 37253 for each additional noncoronary vessel evaluated.

Can 37253 be billed by itself?

No. It is an add-on code and must be reported with an eligible primary procedure; the initial-vessel IVUS code is 37252.

Are units based on ultrasound passes or vessels?

Units correspond to additional vessels, not repeated catheter passes or imaging runs in the same vessel.

What documentation supports an additional unit?

Document the additional vessel examined and the findings and interpretation for that vessel. The record should distinguish it from the initial vessel.

Is 37253 for coronary IVUS?

No. It applies to additional noncoronary vessels. Coronary intravascular ultrasound uses the coronary-specific code family, including 92979 for an additional vessel.

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.
