Encounter for extracorporeal dialysis

This code signifies a patient's visit specifically for the administration of extracorporeal dialysis, a medical procedure that artificially filters waste and excess fluid from the blood when the kidneys are unable to do so. This includes both hemodialysis and hemofiltration performed outside the body.

This code is appropriate for encounters where the primary reason for the visit is the patient receiving their scheduled or unscheduled dialysis treatment. It is used for patients with end-stage renal disease (ESRD) or acute kidney injury requiring this life-sustaining therapy.

• Always sequence this code as the primary diagnosis when the encounter is solely for dialysis.
• Do not use this code for peritoneal dialysis; a different code exists for that modality.
• Ensure supporting documentation clearly indicates the patient received extracorporeal dialysis during the encounter.
