What 90945 covers
Code 90945 captures a dialysis treatment other than hemodialysis together with one physician or other qualified health care professional evaluation during that treatment. Common contexts include nephrologist oversight of peritoneal dialysis or hemofiltration, including continuous renal replacement therapy in an acute-care setting. The service may be provided in hospital or outpatient dialysis settings and is distinct from monthly ESRD management.
Report it when the record supports a non-hemodialysis modality and one evaluation during the dialysis procedure; document the modality, treatment context, and clinician’s assessment. Use 90947 when repeated evaluations are performed for a non-hemodialysis procedure, and select the hemodialysis codes for hemodialysis. CMS assigns a 0-day global period, including same-day preoperative and postoperative care. Do not use modifier 50 for bilateral billing. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
