What 90935 covers
CPT 90935 describes a hemodialysis treatment with one evaluation of the patient by a physician or other qualified health professional. Nephrologists commonly report it for a treatment in a hospital or dialysis facility when they assess the patient during hemodialysis and manage the treatment based on that assessment. It represents treatment-level care, rather than monthly ESRD management.
Report 90935 for the treatment when the clinician performs one evaluation; use 90937 when repeated evaluations are required. The record should identify the hemodialysis treatment, document the clinician’s evaluation and management, and support the number of evaluations. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. CMS allows assistant-at-surgery payment only with documented medical necessity and does not permit co-surgeon or team-surgery billing.
