ICD-10 Code for Hepatitis
The ICD-10-CM code for hepatitis is K75.9 — Inflammatory liver disease, unspecified. This is the code the Alphabetic Index gives for hepatitis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
BillableUnspecified
K75.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which hepatitis code should you use?
The Alphabetic Index lists 57 codes under Hepatitis. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
