Dialysis access
About 36860: External dialysis cannula declotting
Reports clearing clot from an external cannula associated with an arteriovenous shunt or fistula when the access itself is not revised.
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.

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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
