K71 — Toxic liver disease
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.
Code first
The underlying condition must be sequenced before this code.
Use additional code
Add a secondary code to capture the detail described below.
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.
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
