Additional Info
- This is a specific cause of acute (or occasionally subacute) renal disorder/insufficiency.
- The usual marker for this entity is elevated serum urea and/or elevated serum creatinine PLUS an elevated urea:creatinine ratio. The normal value of this ratio (in the units used here) is 44, so a ratio > 66 is suggestive of a pre-renal state. While pre-renal patients are usually intravascularly depleted, this is not universally the case; any situation in which renal perfusion is reduced can give a pre-renal state, even without volume depletion. An example is bilateral renal artery stenosis.
- If the patient qualifies, one could/should also code Kidney, acute renal failure NOS
- Do not use this code if the patient has a pre-existing diagnosis of: Chronic kidney disease (end-stage kidney disease, ESRD), Stage 5
Alternate ICD10s to consider coding instead or in addition
- Kidney, acute renal failure NOS
- Kidney, acute tubular necrosis (ATN)
- Prerenal uremia/state
- Chronic kidney disease (uremia, chronic renal insufficiency) Stage 1
- Chronic kidney disease (uremia, chronic renal insufficiency) Stage 2
- Chronic kidney disease (uremia, chronic renal insufficiency) Stage 3
- Chronic kidney disease (uremia, chronic renal insufficiency) Stage 4
- Chronic kidney disease (end-stage kidney disease, ESRD), Stage 5
Candidate Combined ICD10 codes
- If the patient qualifies, one could/should also code Kidney, acute renal failure NOS
