Endovascular revascularization
About 37297: Additional femoral-popliteal lithotripsy angioplasty
Reports intravascular lithotripsy with angioplasty in each additional femoral-popliteal vessel treated during an endovascular revascularization procedure.
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%.

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 CPT 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
