What 36825 covers
Code 36825 represents surgical creation of hemodialysis access using a vein from the same patient as a conduit, rather than joining a native artery and vein directly. A vascular surgeon typically uses this approach when an autogenous vein graft is selected to establish arteriovenous access. These procedures are generally performed in an operating room for patients needing long-term dialysis access.
Report the access-creation operation when the operative note identifies the patient’s vein as the conduit and distinguishes the construction from direct-anastomosis access or a prosthetic graft. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted. Modifier 50 is inappropriate for this code.

36825 billing questions
How is 36825 different from 36830?
Code 36825 uses the patient’s own vein as the graft conduit. Code 36830 describes access creation using a nonautologous graft.
When should a direct-anastomosis code be used instead?
Use a direct-anastomosis code when the surgeon connects the artery and vein directly without an interposed autologous graft. Codes 36818, 36819, 36820, and 36821 describe direct access creation in specified settings.
Does the 90-day global period include postoperative care?
Yes. The CMS global period includes the day-before preoperative visit and related postoperative care through day 90.
Can modifier 50 be reported?
No. Modifier 50 is inappropriate for this code.
What documentation supports reporting 36825?
The operative note should identify the autologous vein conduit and describe creation of the access using a graft rather than a direct artery-to-vein connection.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction.
