Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
