For a patient with obstructed hemodialysis AV graft, what code signifies that all aspects of the PTA procedure were undertaken?

The code 36902 is designated specifically to represent a percutaneous transluminal angioplasty (PTA) when performed on a dialysis access device such as an arteriovenous (AV) graft. This code captures the entirety of the procedure, confirming that all aspects of PTA, which includes balloon dilation to relieve the obstruction, were completed.

In scenarios involving dialysis access, precision in coding is critical for accurate billing and reflecting the complexity of the treatment provided. Code 36902 indicates that the procedure was performed to restore patency within the vascular access, addressing issues related to flow restrictions or occlusions that may occur over time.

In contrast, the other codes mentioned in the options denote different or additional procedures associated with vascular access issues or combine various aspects rather than representing just the PTA thoroughly. For instance, code 36901 focuses on non-balloon procedures and therefore does not sufficiency describe the complete PTA effort. Similarly, 36905 relates to stenting, making it irrelevant when the primary focus is solely on the PTA itself.

Thus, code 36902 effectively encapsulates the performance of a comprehensive PTA procedure for the treatment of obstructed hemodialysis AV grafts.
