Summary & Overview
CPT 90937: Hemodialysis with Repeated Evaluations
Headline: Repeated-Evaluation Hemodialysis Code CPT 90937 Clarified for National Use
Lead: CPT 90937 represents hemodialysis procedures that include repeated physician evaluations during the dialysis session, with or without substantial revision of the dialysis prescription. The code is central to billing for complex dialysis encounters where ongoing clinical reassessment alters treatment.
What the code represents and why it matters: CPT 90937 is used for hemodialysis encounters requiring repeated assessments and potential prescription changes during the same dialysis session. It distinguishes higher-intensity clinical involvement from single-evaluation dialysis services and affects clinical documentation and billing across outpatient dialysis settings nationally.
Key payers covered: Coverage considerations analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare.
Overview of reader takeaways: Readers will find a concise explanation of the clinical and billing context for CPT 90937, how it differs from single-evaluation dialysis codes, and the typical settings where it is reported. The publication outlines common accompanying diagnoses that justify repeated evaluations, highlights related CPT comparisons for coding clarity, and identifies documentation components tied to this service. Where input fields lacked information, the publication notes "Data not available in the input." This piece is intended to inform coding, compliance, and policy review rather than provide clinical recommendations.
CPT Code Overview
CPT 90937 describes a hemodialysis procedure requiring repeated evaluation(s) with or without substantial revision of dialysis prescription. This code applies to hemodialysis sessions in which the treating clinician performs multiple evaluations of the patient during the course of the dialysis service and may substantially revise the dialysis prescription based on those assessments.
Service Type: Hemodialysis Procedures
Typical Site of Service: End-Stage Renal Disease (ESRD) facility (Place of Service 65) or physician’s office (Place of Service 11)
Clinical & Coding Specifications
A 62-year-old patient with established end-stage renal disease attends a scheduled session at an ESRD facility (Place of Service 65) for maintenance hemodialysis. During the treatment the nephrology physician performs repeated evaluations of the dialysis prescription because the patient develops intradialytic hypotension and signs of inadequate ultrafiltration. The physician evaluates vascular access function, reviews recent laboratory values, adjusts dialysate composition and ultrafiltration rate, and documents substantial revisions to the dialysis prescription before continuing therapy. The facility staff carry out the dialysis procedure while the physician supervises and documents the repeated evaluations and prescription changes. This procedure may also occur in a physician’s office (Place of Service 11) for select patients requiring intensive prescription management.
Modifiers
25— Significant, separately identifiable evaluation and management service by the same physician on the same day as the procedure; used when reporting an E/M service in addition to dialysis codes when the E/M is distinct from the dialysis-related work.
