Resection or repair of an AV fistula aneurysm(s), includes any necessary repair, with or without thrombectomy. As per , only one of R941, R942, R943, R944, R945 or R946 is eligible for payment per patient per day, any physician.

When to Use

Use R945 when performing a formal resection of a symptomatic or enlarging AV fistula aneurysm, regardless of whether a thrombectomy is required during the same session.
Select R945 for repairs involving significant reconstruction of the fistula site that exceeds the scope of simple revision or ligation codes.

Common Pitfalls

Billing R945 in combination with R941, R942, R943, R944, or R946 on the same day will trigger an automatic rejection due to the global restriction per patient per day.
Attempting to unbundle thrombectomy as a separate procedure is a common audit risk; R945 explicitly includes any necessary thrombectomy in its fee.

Billing Tips

Ensure the procedure start time is accurately recorded to determine eligibility for after-hours premiums (E409/E410) or surgical assistant premiums (E400B/E401B), as these are additive to the base R945 fee.
