How many units of the intravascular ultrasound (IVUS) codes ( 37252 , 37253 ) may be assigned for the following scenario? A patient has a lesion extending from the superior vena cava (SVC) through the right innominate vein into the right internal jugular vein. This is a single lesion that will eventually be treated via venous angioplasty and stent placement. Prior to these transcatheter interventions, the IVUS device was used to perform three separate and distinct measurements to assist with selecting the appropriate stent size. The following areas were studied individually: (1) SVC; (2) right innominate vein; and (3) right internal jugular vein. Secondary to this, a fourth diagnostic IVUS measurement was performed in the left internal jugular vein. In addition, would the study of the left internal jugular vein be reported with code 37252 or 37253 ? ...

Article Overview

This premium article addresses a CPT-based question involving intravascular ultrasound (IVUS) reporting in a venous intervention scenario. It discusses how the service is viewed when a lesion spans more than one vessel and how a separate vessel study is handled for reporting purposes. The article is useful for coders, compliance staff, and clinicians working with vascular imaging, venous interventions, and CPT code interpretation.

Why This Topic Matters

IVUS reporting can affect procedure coding accuracy when imaging is performed across multiple adjacent vessels. Understanding the relevant CPT guidance helps avoid inconsistent unit reporting and supports correct documentation for venous intervention cases.

Codes Discussed

• CPT: 37252
• CPT: 37253
