What 36860 covers

This service clears thrombus from an external cannula used with an arteriovenous shunt or fistula for hemodialysis. It is distinct from removing clot from the access circuit itself or surgically revising the access. A physician who manages dialysis access, commonly a vascular surgeon or access surgeon, may perform it when cannula obstruction interferes with use of the access.

Report the code when documentation identifies the external cannula as the site of clot and shows that declotting was performed without access revision. Record the access involved, the obstructing clot, the work performed, and the result. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery is not paid; co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

36831Fistula thrombectomy
Choose 36860 when declotting is confined to the external cannula and the access is not revised. Choose 36831 for open thrombectomy of the arteriovenous fistula.
36861Cannula declotting
These codes distinguish external-cannula declotting without revision from related cannula declotting associated with revision. Base selection on the documented procedure performed.
36833Fistula revision
Code 36833 addresses revision of the fistula with thrombectomy; 36860 is limited to declotting the external cannula without access revision.

36860 billing questions

How is this different from 36831?

Use 36860 for clot cleared from the external cannula without revising the access. Code 36831 describes open thrombectomy of the arteriovenous fistula itself.

When would 36861 be considered instead?

36861 is the related cannula-declotting code associated with revision. This code is for declotting the external cannula without access revision.

What documentation supports reporting 36860?

Document that the clot was in the external cannula, the declotting work performed, and whether the access was revised. The record should distinguish cannula clearing from thrombectomy of the access.

Is same-day care included in the payment?

Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.

Can modifier 50 or an assistant-at-surgery claim be reported?

Modifier 50 is inappropriate for this code. CMS does not pay an assistant at surgery for it.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full; other procedures are subject to the standard multiple procedure reduction. Co-surgeon and team-surgery billing are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
