What 36800 covers

This service involves surgically placing a cannula to provide vascular access for hemodialysis or another extracorporeal purpose. It is performed by a surgeon, commonly a vascular surgeon, in an operating room or other facility setting. The operative note should identify the vessels accessed, the cannula placement, and the purpose of the access so the service can be distinguished from construction of an arteriovenous fistula or graft.

Report the code for the cannula insertion itself, not for creating or revising a fistula or graft. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery 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

36810Dialysis cannula
Both codes concern cannula insertion, but their full descriptors distinguish the services. Verify the documented procedure against each descriptor rather than selecting by the shared short description.
36815Dialysis cannula
This is another cannula-insertion code with a distinct descriptor. Choose based on the actual cannula service documented, not simply the fact that dialysis access was involved.
36821Dialysis access
Use 36821 for direct creation of an arteriovenous fistula. Use 36800 when the documented service is insertion of a cannula, not fistula construction.
36825Dialysis access
Code 36825 describes creation of arteriovenous access with an autogenous graft; 36800 describes cannula insertion.

36800 billing questions

How is this different from an arteriovenous fistula code?

This code reports surgical cannula placement. Codes such as 36821 describe construction of an arteriovenous fistula, a different access procedure.

What documentation supports reporting this service?

Document the cannula placement, the vessels involved, and the clinical purpose of the access. The operative record should make clear that the service was cannula insertion rather than fistula or graft construction.

Can modifier 50 be reported for bilateral cannula insertion?

No. CMS identifies bilateral adjustment as inappropriate for this code.

Is an assistant surgeon payable?

No. Medicare's statutory restriction prevents assistant-at-surgery payment for this code. Co-surgeons and team surgery are also not permitted.

How are other procedures performed in the same session paid?

The highest-valued procedure is paid in full; other procedures performed in that session are subject to the standard multiple-procedure reduction.

What care is included in the global period?

The code has a 0-day global period. Same-day preoperative and postoperative care is included.

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.
