What 90947 covers

This service covers repeated clinical evaluations during a dialysis procedure that is not hemodialysis. Examples include peritoneal dialysis and continuous renal replacement therapy. A nephrologist or another qualified health care professional may assess the patient’s response, review treatment parameters, and adjust the dialysis prescription in a hospital or other dialysis setting. The repeated evaluations distinguish this service from the corresponding non-hemodialysis service involving a single evaluation.

Report 90947 for the dialysis service when documentation supports multiple evaluations during treatment; it is not a separate charge for each check. Record the dialysis modality, the evaluations performed, the patient’s response, and any prescription changes. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are 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.
