K71 is a non-billable ICD-10-CM category code for toxic liver disease, so it cannot be submitted on claims. Use a more specific code from this category instead, such as K71.0, K71.10, K71.11, and K71.2.

Questions About K71Overview

What is the ICD-10 code for toxic liver disease?

K71 is the ICD-10-CM category for toxic liver disease, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is K71 (Toxic liver disease) a billable code?

No. This is a category header that groups the codes for toxic liver disease, and headers cannot be submitted on claims. Claims for toxic liver disease need a more specific code from this category, such as K71.0, K71.10, and K71.11.

Can K71 be reported with R17?

Not as a rule. The Excludes1 note at block K70-K77, which applies to K71, lists "jaundice NOS (R17)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does K71 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5). The additional code is reported after K71.
