ICD-10 Code K71.6 – Toxic liver disease with hepatitis, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.6 – Toxic liver disease with hepatitis, not elsewhere classified
What it is
K71.6 identifies liver injury caused by a toxic substance when hepatitis is present and the cause is not otherwise classified. Use it for documented toxic or drug-related hepatitis when the record does not specify a more exact toxic liver disease code.
Clinical signs
Typical documentation may note hepatitis with liver inflammation, jaundice, abdominal discomfort, or abnormal liver tests. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents toxic liver disease with hepatitis and does not name a specific agent or a more precise toxic liver diagnosis. It may apply after medication exposure, chemical exposure, or other toxic injury when hepatitis is the recorded liver manifestation.
Code only when the chart supports a toxic cause rather than viral, alcoholic, or autoimmune hepatitis. If the documentation is unclear, check documentation before assigning K71.6.
Do not use for
Do not use this code for hepatitis with a known viral cause, alcoholic liver disease, or unspecified hepatitis without toxic etiology. Do not use it when another K71 category better matches the documented toxic liver condition.
Coding tip
Look for the exact toxic cause and any additional liver injury details, then code the most specific K71 option supported by the record.
