Additional Info
Do NOT use this code if the patient has a pre-existing diagnosis of: Chronic kidney disease (end-stage kidney disease, ESRD), Stage 5
This code includes the following conditions that don't have separate ICD10 codes:
- Acute Kidney Injury (AKI)
- acute renal insufficiency (ARI)
Do not use this code if the AKI is postoperative or postprocedural, use Kidney, acute renal failure, postprocedural
The KDIGO guidelines identify that this is present if any one or more of the following are true:
- Increase in serum creatinine by 26 micromoles/L or more within 48 hours
- Increase in serum creatinine to 1.5 times baseline or more within the last 7 days
- Urine output less than 0.5 mL/kg/hour for 6 hours
Template:Discussion I double checked with our lab values, and it looks like our EPR results are measured in micromoles/L. Using the guidelines listed above, that would mean that any patient who has a rise in creatinine over a 2 day period equal or greater to 26, would be coded as "acute renal failure NOS". For example, a patient whose creatinine rises from 120 to 150 within 48 hours, would receive this code. I feel like I am reading these instructions wrong, because this would mean a large number of patients would fall into this category.Mlagadi 14:01, 2018 October 16 (CDT)

- Also code the cause, if known.

There are a number of coding rules related to renal diagnoses, centralized info about them is in Renal Coding Considerations for ICD10.

Legacy Info
We understand that the definition in the ICD10 codes is different than the definition in ARF (Diagnosis) and ARI and CRF - Chronic Renal Failure was. We are OK with that and will use the new definitions for the new codes, and the old ones for the old codes. Hopefully we can limit the amount of time where we consider both.
