K73.8 — Other chronic hepatitis, not elsewhere classified
Is K73.8 billable?
Yes, but K73.8 is an unspecified code. K73.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, K73.8 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting K73.8 — the more specific alternatives are listed below.

How is K73.8 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to K73.8. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Hepatitis › chronic › specified NEC
Excludes1 — never code together — inherited from K70-K77
The conditions below can never be reported together with K73.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- jaundice NOS (R17)
