What 36821 covers

A vascular surgeon creates a direct connection between a native artery and a native vein to establish an arteriovenous access for hemodialysis. The procedure is generally performed in an operating room, including hospital outpatient or inpatient settings. The operative report should identify the vessels and site, describe the direct connection, and make clear that no graft was used.

Select this code when the documented construction is a direct artery-to-vein anastomosis, rather than a site-specific technique or a graft-based access. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team-surgery billing is 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.

36821 billing questions

How is this code distinguished from 36820?

This code describes a direct artery-to-vein connection at any site. Code 36820 identifies the forearm-vein technique; use the operative details and applicable site-specific code description to select between them.

Can this code be used when a graft is placed?

No. It describes a direct connection between native vessels without an interposed graft. A graft-based access is represented by a different code, with the choice depending on graft material.

Are the preoperative visit and postoperative care separately reported?

The day-before preoperative visit and related postoperative care during the 90-day global period are included in this surgery's global payment.

Can modifier 50 be used for access creation on both sides?

Modifier 50 is inappropriate for this code. Report the service based on the documented operative site and procedure.

How are assistant and co-surgeon services handled?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team-surgery billing is 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.
