Additional Info
- This stage is defined by having chronic renal insufficiency/disease with: Glomerular filtration rate (GFR) >90 mL/minTo
To calculate the GFR, use this easy website calculator: https://www.mdcalc.com/mdrd-gfr-equation
- It requires age, sex, race (black vs. white) and creatinine:
- Unless you know otherwise, use "white" race as default
- Use the most recent, stable, PRE-HOSPITAL creatinine value available
- When no creatinine clearance is listed, but the patient is a known dialysis patient then code Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15
- For all other CKD patients, i.e. those in whom we cannot easily identify the Stage, we’ll use Chronic kidney/renal disease, NOS (stage unspecified).
Alternate ICD10s to consider coding instead or in addition
Candidate Combined ICD10 codes
- Code the cause, if known.
