K71Toxic liver disease

Non-billable headerICD-10-CM

K71 is a non-billable header ICD-10-CM code for toxic liver disease. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • alcoholic liver disease (K70.-)
  • Budd-Chiari syndrome (I82.0)

Code first

The underlying condition must be sequenced before this code.

  • poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)

Use additional code

Add a secondary code to capture the detail described below.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Includes

Conditions this code covers.

  • drug-induced idiosyncratic (unpredictable) liver disease
  • drug-induced toxic (predictable) liver disease

Other codes that can never be billed with K71

These codes carry an Excludes1 note pointing at K71. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K71 alone.

  • R18Ascites
  • K72Hepatic failure, not elsewhere classified
  • K73Chronic hepatitis, not elsewhere classified
  • K74Fibrosis and cirrhosis of liver

Risk adjustment

K71 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead K71

10 child codes. Green means billable.
