Additional Info

See ICD10 Guideline for Renal Coding#About Coding Chronic Kidney Disease (CKD)


  • This stage is defined by having chronic renal insufficiency/disease with:
    • being on chronic dialysis (of any type) (this is the most common case)

To calculate the GFR, use this easy website calculator:

ESRD vs Acute Renal Failure

  • UNLESS the patient has had a renal transplant and the transplanted kidney was functioning (and thus can experience acute renal failure)

About "Acute on Chronic renal failure"

  • Our definition for CRF includes two things, as above. If you are on dialysis then it is technically not possible to also have acute renal failure. And while our threshold of creatinine clearance < 15 ml/min USUALLY gets people on dialysis, that's not always the case. In other words, there are some people who don't need to start dialysis until their clearance is <10 or even 8 ml/min. THOSE people who by our definition have Stage 5 CKD cannot have ARF but rather this is considered a progression of their underlying disease. Instead of coding ARF, code the reason for dialysis ie. Fluid overload, Hyperkalemia, severe or symptomatic etc combined with Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15
  • And of course, if you previously had Stage 5, were on dialysis, then got a successful renal transplant, then you CAN get acute renal failure in your graft.

Admission for missed dialysis


  • HD (Hemodialysis) from CCI picklist, as an acquired procedure if done while on your unit.

Kidney Transplant Coding Guidelines

For general coding information in the context of kidney transplants see Kidney Transplant Coding Guidelines. This includes how to code patients before, during and after their transplant admission.

Candidate Combined ICD10 codes

  • Code the cause, if known.
