What codes correspond to the insertion of arterial catheters?

The correct selection for the insertion of arterial catheters is based on a thorough understanding of the relevant coding guidelines in the Current Procedural Terminology (CPT) system, specifically for vascular access procedures. The codes 36620 and 36625 correspond to the insertion of arterial catheters.

36620 is specifically for the insertion of a catheter into an artery, which is the primary procedure when establishing arterial access for monitoring or intervention. This code reflects the technical aspects and the skill required to successfully perform the procedure, allowing healthcare providers to report this action accurately for billing and documentation purposes. 36625 extends this concept by addressing the insertion of a catheter into a second artery.

In contrast, the other codes listed refer to different types of vascular procedures. For example, 36555 and 36556 pertain to the insertion of central venous catheters and not arterial catheters. Similarly, 36415 and 36416 involve venous procedures, such as the collection of venous blood samples or venipuncture, and are unrelated to catheterization of arteries. Lastly, 36561 and 36562 are also focused on venous access and not appropriate for arterial catheters. Understanding these distinctions is crucial
