    Typical Clinical Scenarios

    • An adult with end-stage renal disease on maintenance hemodialysis presents to the outpatient dialysis center for a scheduled dialysis session; routine pre-dialysis assessment notes stable vital signs and a functioning arteriovenous fistula, and the encounter is documented solely for the provision of chronic dialysis care. Typical codes: Z49.01, Z49.31
    • A pediatric patient with chronic kidney failure is admitted for initiation of peritoneal dialysis training and catheter placement on an elective basis; the visit documents the dialysis modality initiation and ongoing outpatient dialysis management needs. Typical codes: Z49.02, Z49.32
    • An adult with acute kidney injury requiring temporary in-hospital hemodialysis is seen for dialysis sessions during a hospital stay complicated by fluid overload and electrolyte imbalance; the dialysis encounters during the admission are coded to reflect the provision of dialysis care during the acute treatment course. Typical codes: Z49.01, Z49.31
