ICD-10 Code K77 – Liver disorders in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K77 – Liver disorders in diseases classified elsewhere
What it is
K77 identifies liver disorder that results from another underlying disease, rather than a primary liver condition. Use it when the liver involvement is documented as secondary to a separate, known cause.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal liver assessment, hepatomegaly, or other evidence of liver involvement linked to the primary disease.
When to use this code
Use K77 when the record states the liver disorder is due to another condition and no more specific liver code applies. Confirm the underlying disease is documented and coded separately when required. If the note is unclear, check documentation before assigning this code.
Do not use for
Do not use K77 for primary liver diseases such as hepatitis, cirrhosis, or fatty liver when those are the documented diagnosis. Also avoid it when the liver finding is incidental or not clearly linked to another disease.
Coding tip
Always code the underlying condition first when documentation supports a secondary liver disorder.
