CPT 90993: Dialysis Self-Care and Treatment Training Session
CPT code 90993 designates a single session of dialysis self-care and treatment training when a complete course has not yet been finished. It captures clinician time devoted to instructing a patient or caregiver on dialysis procedures, techniques, and safety, and is relevant to programs emphasizing patient autonomy and home dialysis readiness. Nationally, proper use of this code supports documentation of incremental training encounters and ties clinical education to billing for dialysis programs across outpatient dialysis centers and clinics.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an explanation of the code’s clinical intent and common service settings, comparisons to related dialysis codes (including completed-course training and unlisted dialysis procedures), and the typical billing context for partial training courses. The publication outlines common use cases, associated ICD-10 diagnoses that commonly accompany training sessions, and the role of CPT code 90993 within end-stage renal disease care pathways.
Intended for coders, dialysis program managers, and policy analysts, the analysis clarifies where 90993 fits within dialysis billing workflows, highlights relevant clinical scenarios such as training for hemodialysis and peritoneal dialysis techniques, and provides guidance on documentation elements that support reporting of each incomplete training session.
