ICD10 Guideline for Renal Coding

This page contains an ICD10 Coding Guideline for ICD10 collection. See ICD10 coding guidelines for similar pages.

See also Renal Coding Considerations (old) for coding in the old system.

General Considerations

• Renal-related issues in ICD10 may include any of these things:

About Coding Chronic Kidney Disease (CKD)

• The following ICD10 codes can apply to CKD

• When there is a Creatinine clearance / GFR listed, it will be used to specify between Stages 1, 2, 3, 4, 5

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).

AKI

• ICD10 does not have specific diagnosis of AKI (acute kidney injury), instead the codes that cover this are any of:
  • Kidney, acute renal failure NOS
  • Kidney, acute renal failure, postprocedural

Candidate Combined ICD10 codes for renal codes

• Other codes you might want to use include:
  • Prerenal uremia/state
  • Hepatorenal syndrome
  • Kidney, nephropathy, drug or toxin induced
  • Nephritic syndrome, acute
  • Kidney, tubulo-interstitial nephritis/disease

ESRD vs Acute Renal Failure

• Do NOT code both
  • Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15

AND

• Any of the acute renal failure diagnoses (Kidney, acute tubular necrosis (ATN), Kidney, acute renal failure NOS, Kidney, renal failure/insufficiency/uremia, unspecified as acute or chronic, Kidney, acute renal failure, postprocedural)

• 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.

Kidney transplant vs ESRD

• If the patient has a Past history, transplanted kidney, do not also code the Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15 that occurred in the native kidneys, which was the reason for the transplant because having had ESRD is implied in having had a kidney transplant.
  • Exception: If the transplanted kidney has completely failed (e.g. the patient is back on dialysis), then do also code: Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15, because now it applies to the transplanted kidney. Also code Kidney transplant, failure or rejection or unspecified complication.

Data Integrity Checks

CCMDB Data Integrity Checks

• Query check_ICD10_no_ESRD_w_ARF
• Query check ApARF CR
• Can't check ICD10 ARF vs APACHE ARF

Data Integrity Checks that can not be checked before sending

• Check CRF/ARF against TISS Dialysis
