K76.3 is a billable ICD-10-CM diagnosis code for infarction of liver. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 441 through 443, 791, 793. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 8 closely related codes. Coders also document this condition as hepatic infarction. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified liver disease.

Questions About K76.3Overview

What is the ICD-10 code for infarction of liver?

The ICD-10-CM code for infarction of liver is K76.3 (sometimes written as K763). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is K76.3 (Other diseases of liver) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report infarction of liver on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does K76.3 group to?

Is K76.3 a CC or MCC?

CMS lists K76.3 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 8 closely related codes in its exclusion list.

Not as a rule. The Excludes1 note at block K70-K77, which applies to K76.3, 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).
