What 37298 covers
This service is endovascular balloon angioplasty of an artery below the ankle, such as a pedal artery, when the treated lesion meets the billing code definition of complex. It is commonly performed by a vascular surgeon, interventional radiologist, or interventional cardiologist in a hospital or outpatient angiography suite for limb-threatening ischemia, including patients with foot wounds and impaired distal blood flow. The code identifies angioplasty in the inframalleolar territory; it is not selected merely because the patient has a complex medical history or a difficult procedure overall.
Report this code for the initial treated vessel in the inframalleolar territory when the lesion qualifies as complex under the code-set criteria. The procedure note should identify the treated artery, lesion and intervention, and document the features supporting complex classification. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

37298 billing questions
How does this differ from 37296?
Both describe angioplasty in the inframalleolar territory for the initial vessel. Use 37298 when the lesion meets the billing code definition of complex; use 37296 for a simple lesion.
When is 37299 reported with this code?
37299 describes complex angioplasty in each additional inframalleolar vessel. Report it for qualifying additional vessels, rather than using 37298 again for each vessel.
What documentation supports complex classification?
Document the treated inframalleolar artery, lesion characteristics, and procedural details that establish the billing code complex category. The patient's overall clinical complexity alone does not determine the code level.
How does CMS handle multiple procedures in the same session?
The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple-procedure reduction.
Can modifier 50 be used for bilateral treatment?
CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%. Documentation should support treatment on both sides.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
