{{discussion}}This definition is in contrast to the old ARF definition in which we code acute renal failure ONLY if the patient receives dialysis during their admission. There creatinine levels/urine output is not enough to code renal failure (the only exception to this rule was in the ICU apache score, in which you could code ARF in the apache tab based on creat/urine output).  The codes will be inconsistent between the old diagnosis codes and the ICD10.
In addition to this, if we wanted to code acute renal insufficiency our criteria was as follows: A Rise >100 mmol from baseline over 24 hours,
If the prior Creatinine level is unknown use > 250 as a guideline to code ARI. If patients baseline creatinine was > or equal to 250 last admission code as ARI if the present creatinine was 350 or more.
I just want to make sure that we are coding this properly, as we have many patients coming in with renal issues/not sure how important consistency between collecting the old way and the new way is. [[User:Mlagadi|Mlagadi]] 11:47, 2018 June 28 (CDT)

ICD10 Diagnosis
Dx: Kidney, acute renal failure NOS
ICD10 code: N17.9
Pre-ICD10 counterpart: ARF, ARI
Charlson/ALERT Scale: none
APACHE Como Component: none
APACHE Acute Component: 2019-0: Renal/Metabolic NOS, 2019-0: Metabolic/Renal NOS

External ICD10 Documentation

This diagnosis is a part of ICD10 collection.

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

Alternate ICD10s to consider coding instead or in addition

Candidate Combined ICD10 codes

  • Also code the cause, if known.

Template:Data Integrity Checks

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

Related CCI Codes

Legacy Info

This definition is in contrast to the old ARF definition in which we code acute renal failure ONLY if the patient receives dialysis during their admission. There creatinine levels/urine output is not enough to code renal failure (the only exception to this rule was in the ICU apache score, in which you could code ARF in the apache tab based on creat/urine output). The codes will be inconsistent between the old diagnosis codes and the ICD10.

In addition to this, if we wanted to code acute renal insufficiency our criteria was as follows: A Rise >100 mmol from baseline over 24 hours, If the prior Creatinine level is unknown use > 250 as a guideline to code ARI. If patients baseline creatinine was > or equal to 250 last admission code as ARI if the present creatinine was 350 or more.

I just want to make sure that we are coding this properly, as we have many patients coming in with renal issues/not sure how important consistency between collecting the old way and the new way is. Mlagadi 11:47, 2018 June 28 (CDT)
