When to Use

Use R942 for the elective or urgent surgical ligation or excision of a non-functioning AV fistula or graft that is no longer required for dialysis access.
Use R942 when managing complications such as an infected AV graft or a symptomatic aneurysm that necessitates the complete removal or obliteration of the access site.

Common Pitfalls

Billing R942 on the same day as R841 or R833 will result in an automatic rejection; ensure these procedures are scheduled on separate days.
Attempting to bill multiple codes from the R941-R946 series for the same patient on the same day is prohibited, as only one procedure from this group is payable per patient per day.

Billing Tips

Ensure the operative report clearly details the extent of the ligation or removal to support the use of R942 over minor procedural codes.
If the procedure is performed after hours or on a weekend, remember to append the appropriate E-series premium (e.g., E409 or E410) to the procedural fee to maximize reimbursement.
