About 90945: Non-hemodialysis dialysis evaluation
Reports a dialysis treatment other than hemodialysis with one physician or qualified health care professional evaluation during the treatment.
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.

90945 billing questions
How do I choose between 90945 and 90947?
Use 90945 for one evaluation during a dialysis procedure other than hemodialysis. Use 90947 when repeated evaluations are performed during that non-hemodialysis procedure.
How does 90945 differ from 90935?
90945 is for dialysis other than hemodialysis, such as peritoneal dialysis or hemofiltration. 90935 is the single-evaluation code when the treatment is hemodialysis.
What documentation supports reporting 90945?
Document the dialysis modality, the treatment context, and the physician’s or qualified health care professional’s evaluation during the procedure.
Should modifier 50 be appended?
No. This dialysis service is not a bilateral procedure, so modifier 50 is inappropriate.
How does the global period affect same-day care?
The 0-day global period includes same-day preoperative and postoperative care. CMS assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
