What 37297 covers
This add-on represents intravascular lithotripsy with angioplasty in an additional vessel in the femoral-popliteal territory. The catheter-based treatment uses sonic pressure waves to modify calcified arterial plaque, followed by angioplasty in the treated vessel. Vascular surgeons, interventional radiologists, and interventional cardiologists commonly perform these procedures in a hospital or outpatient catheterization suite.
Report this code for each qualifying additional vessel after the initial vessel service, using the applicable code for the initial vessel and lesion complexity. The operative report should identify the treated vessels and sides, describe the lithotripsy and angioplasty performed, and support the vessel count and complexity level selected. This is an add-on code and must be billed with a primary procedure; payment is within that procedure's global period. For bilateral reporting with modifier 50, CMS pays 150%.
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.

How to choose
- 37296Foot artery angioplasty
- Use 37296 for the initial vessel in the applicable procedure; use 37297 for each qualifying additional vessel.
- 37298Foot artery angioplasty
- 37298 represents the initial vessel when the lesion meets the complex-lesion criteria; 37297 is for an additional vessel at the applicable noncomplex level.
- 37299Lithotripsy angioplasty
- 37299 represents each additional vessel for a complex lesion. Choose it rather than 37297 when the billing code complexity criteria are met.
37297 billing questions
Can 37297 be billed by itself?
No. It is an add-on for an additional vessel and must be reported with the applicable primary procedure, such as 37296 for the initial vessel.
How does 37297 differ from 37296?
37296 represents the initial vessel; 37297 represents each qualifying additional vessel treated in the femoral-popliteal territory.
When is 37299 used instead?
37299 is the corresponding additional-vessel code for a complex lesion. Select between it and 37297 using the billing code lesion-complexity criteria.
What documentation supports reporting an additional vessel?
Document the specific vessels treated, the intravascular lithotripsy and angioplasty performed, and the lesion complexity supporting the code selection.
How is bilateral treatment reported?
For bilateral reporting with modifier 50, CMS pays 150%. The add-on still must accompany its primary procedure.
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.
