ICD-10 Code B58.1 – Toxoplasma hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B58.1 – Toxoplasma hepatitis
What it is
This code identifies hepatitis caused by infection with Toxoplasma gondii. Use it when the record clearly documents toxoplasma involvement of the liver.
Clinical signs
Clinical features vary; refer to documentation. Findings may include hepatitis with liver involvement in the setting of confirmed toxoplasmosis, but the chart should support the diagnosis.
When to use this code
Use B58.1 when the provider documents toxoplasma hepatitis, toxoplasmic liver disease, or hepatitis attributed to Toxoplasma gondii. Code it when the liver condition is part of the active diagnosis being treated or evaluated. If the note only says toxoplasmosis without hepatic involvement, do not assume this code.
Do not use for
Do not use this code for unspecified toxoplasmosis, isolated hepatitis of another cause, or a suspected infection not confirmed in the record. Check documentation.
Coding tip
Confirm that the provider links hepatitis to toxoplasma before assigning B58.1.
