ICD-10 Code K71.9 – Toxic liver disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.9 – Toxic liver disease, unspecified
What it is
K71.9 identifies toxic liver disease when the specific cause, pattern, or type is not documented. Use it for liver injury attributed to a toxin, drug, or chemical when details are insufficient.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal liver tests, jaundice, right upper quadrant discomfort, or a history suggesting exposure to a hepatotoxic agent.
When to use this code
Use K71.9 when the record states toxic liver disease but does not specify the agent or the exact liver disorder. It also fits when the clinician documents suspected toxic liver injury and no further detail is available. Check documentation if another toxic liver disease code is supported.
Do not use for
Do not use this code when the toxic agent or specific liver condition is documented and a more precise K71 code applies. Do not use it for non-toxic liver diseases, such as viral or alcoholic causes, unless documented separately.
Coding tip
Query for the offending substance and the exact liver diagnosis before defaulting to K71.9.
