What 90937 covers

This service captures physician management during a hemodialysis treatment when the patient requires repeated clinical evaluations during that session. A nephrologist or other physician assesses the patient’s response to dialysis more than once and may make a substantial change to the dialysis prescription; a prescription change is not required when repeated evaluations are documented. It is used for in-center or hospital hemodialysis encounters, not simply because the patient receives recurring dialysis.

Choose 90937 rather than 90935 when repeated evaluations, rather than a single evaluation, support the service. Report the treatment once, not one unit for each assessment. The record should identify the serial assessments, clinical findings, response to treatment, and any resulting prescription decisions. 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.

90937 billing questions

When should 90937 be chosen over 90935?

Use 90937 when the physician performs repeated clinical evaluations during the hemodialysis session. Use 90935 when the documented service involves a single evaluation.

Does the physician have to change the dialysis prescription?

No. Repeated evaluations support 90937 even when the prescription remains unchanged, provided the record documents the assessments and clinical findings.

Should each evaluation be billed as a separate unit?

No. Report the hemodialysis treatment once; the repeated evaluations distinguish 90937 from a single-evaluation service.

90937 describes repeated physician evaluations during hemodialysis. 90947 is for repeated evaluations during a dialysis procedure other than hemodialysis.
