CPT 37285 Tibial/Peroneal Stent Reimbursement

CPT code 37285 covers placement of a vascular stent in an additional tibial or peroneal artery during the same session as an initial tibial or peroneal revascularization. The service includes stent deployment and any angioplasty performed for a straightforward stenotic lesion in the anterior tibial, posterior tibial, or peroneal arteries, and encompasses access, catheterization, lesion crossing, and imaging guidance needed to complete the procedure. Nationally, this code is important for coding and reimbursement of add-on endovascular interventions in peripheral arterial disease management where multiple tibial/peroneal vessels are treated in one operative session.

Key payers evaluated include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for use of the code, typical sites of service, and what the code represents for procedural documentation. The publication also highlights benchmarking and policy-relevant topics readers can expect: national payment and utilization benchmarks, common billing considerations for same-session add-on stent placement, and potential payer coverage patterns affecting interventional peripheral arterial care.

Billing Code Overview

CPT code 37285 describes stent placement in the tibial and peroneal vascular territory performed during the same session as an initial tibial or peroneal revascularization service. The procedure covers deployment of a vascular stent, with angioplasty when performed, for a straightforward lesion (stenosis) in an additional tibial or peroneal vessel. The tibial and peroneal territory includes the anterior tibial, posterior tibial, and peroneal arteries.

Service type: Endovascular peripheral arterial stent placement performed as an add-on during the same session as a primary tibial or peroneal revascularization.

Typical site of service: Hospital-based or outpatient endovascular suite or catheterization laboratory, where arterial access, catheterization, lesion crossing, imaging guidance, and stent deployment are performed.

Data not available in the input.

Clinical Context

A typical patient is an older adult with peripheral artery disease (PAD) who presents with lifestyle-limiting claudication or ischemic rest pain and nonhealing lower-extremity ulceration. The patient has multilevel tibial and/or peroneal disease and is taken to the angiography suite for endovascular revascularization. During the same endovascular session as the initial tibial or peroneal angioplasty/stent of a primary target vessel, the operator identifies an additional straightforward focal stenosis in another tibial/peroneal artery (anterior tibial, posterior tibial, or peroneal artery). After crossing the lesion with guidewires and performing angioplasty as indicated, the operator deploys a small peripheral stent in that additional vessel to restore inline flow to the foot. The service includes vascular access (commonly femoral or pedal), catheterization of the ipsilateral limb, lesion crossing, intraprocedural imaging (digital subtraction angiography), and any immediate adjunctive angioplasty needed to optimize stent expansion.

Clinical workflow steps:

Referral and preprocedure evaluation with review of noninvasive testing (duplex ultrasound, ABI/TBI) and assessment of wound/ischemia severity.
Informed consent and perioperative optimization (antiplatelet strategy, anticoagulation review).
Procedural access (antegrade common femoral, contralateral crossover, or pedal puncture), diagnostic angiography to map tibial/peroneal anatomy, and initial angioplasty/stent of the primary tibial/peroneal target.
Identification of an additional straightforward lesion in a separate tibial/peroneal vessel and performance of angioplasty plus deployment of a small stent in that additional vessel during the same session (37285).
Completion angiography to confirm technical success, hemostasis at access site, and postprocedure monitoring with discharge planning that addresses antiplatelet therapy and wound care if applicable.

`26`	Professional component	Use when reporting only the professional interpretation component of a diagnostic study associated with the procedure.

`77`	Repeat procedure by another physician	Use when a second physician repeats the procedure on the same day.
`78`	Return to the operating/procedure room for a related procedure during the postoperative period	Use when an unplanned return to the procedure room for a related procedure is required during the global period.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during a global period.
`XE`	Separate encounter, distinct from the day of the procedure (Modifier XE, subset of -59 HCPCS modifiers)	Use to report a distinct procedural service performed at a separate encounter.
`XS`	Separate structure, distinct organ/structure (Modifier XS)	Use when procedures involve distinct vessels or anatomic structures to support distinct service reporting.
