Bilateral Endovascular Revascularization Coding Alert: What You Need to Know for 2026

As coding guidance evolves, staying aligned with new CPT updates is critical, especially for high-impact vascular procedures. The 2026 introduction of CPT codes 37254–37299 brings important changes for reporting lower extremity endovascular revascularization services. If your team is coding for peripheral arterial disease (PAD) interventions, understanding how to correctly report bilateral procedures is essential to avoid denials and ensure accurate reimbursement.

Endovascular revascularization is a minimally invasive procedure used to treat lower extremity peripheral arterial disease (PAD). These procedures restore blood flow by clearing blockages or widening narrowed arteries in the legs—helping reduce pain, improve mobility, and prevent more serious complications.

From a coding standpoint, these services can be performed:

The new CPT code range 37254–37299 is designed to better capture the complexity and variation of lower extremity revascularization procedures. However, with this expanded range comes more nuanced billing rules particularly when procedures are performed bilaterally.

One of the most important distinctions in this update is how bilateral procedures are reported. Depending on the specific CPT code, you will either:

This distinction is not arbitrary it is based on parenthetical guidance within the CPT codebook. Applying the wrong method can lead to claim rejections or underpayment.

Use Modifier 50

Apply Modifier 50 to the following codes when procedures are performed bilaterally:

37254, 37256, 37258, 37260, 37263, 37265, 36267, 37269, 37271, 37273, 37275, 37277, 37280, 37282, 37284, 37286, 37288, 37290, 37292, 37294, 37296, 37298

For the following codes, report each side separately (i.e., list the code twice):

37255, 37257, 37259, 37261, 37262, 37264, 37266, 37268, 37270, 37272, 37274, 37276, 37278, 37279, 37281, 37283, 37285, 37287, 37289, 37291, 37293, 37295, 37297, 37299

Incorrect bilateral coding is a common, and costly, mistake. Misapplication of Modifier 50 or failure to report procedures correctly can result in:

For coding teams already managing complex vascular procedures, these nuances add another layer of difficulty.

Navigating CPT updates shouldn’t slow your team down. TruBridge Encoder is designed to simplify complex coding scenarios like bilateral endovascular revascularization.

With TruBridge Encoder, your team can:

Instead of second-guessing bilateral rules, your coders can move forward with confidence improving both accuracy and productivity.

The 2026 CPT updates for lower extremity endovascular revascularization introduce important changes especially in how bilateral procedures are reported. Understanding when to use Modifier 50 vs. reporting codes twice is key to clean claims and optimal reimbursement.

If your organization is looking to streamline coding workflows and reduce risk, tools like TruBridge Encoder can make a measurable difference.
