Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
