0.000What This Code Means
A patient requires regular kidney dialysis treatment to filter waste products from their blood because their kidneys no longer function adequately. This code indicates the patient's dependence on this life-sustaining treatment.
Coding Tips
- •Use this code for patients on any type of dialysis (hemodialysis, peritoneal dialysis, or continuous renal replacement therapy)
- •This is a status code that should be reported for every encounter where the patient is dialysis-dependent; pair with the underlying kidney disease code (N18.x series)
Clinical Significance
This code represents complete dependence on regular dialysis for survival due to end-stage renal disease, indicating extremely high mortality risk without treatment and complex ongoing medical management needs. These patients require lifelong dialysis access care, fluid management, and monitoring for dialysis-related complications.
Documentation Requirements
- ✓Confirmation of dialysis dependence
- ✓Type of dialysis (hemodialysis vs peritoneal)
- ✓Dialysis schedule and frequency

- ✓Dialysis adequacy parameters
- ✓Fluid restriction requirements
- ✓Underlying kidney disease etiology
- ✓Transplant candidacy status
Excludes 1 — Do NOT code together
- encounter for fitting and adjustment of dialysis catheter (Z49.0-)
Excludes 2 — Not included here, may code separately
- noncompliance with renal dialysis (Z91.15-)
