ICD-10 Code K76.4 – Peliosis hepatis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K76.4 – Peliosis hepatis
What it is
Peliosis hepatis is a rare liver condition marked by blood-filled spaces within the liver tissue. Use this code when the record specifically identifies peliosis hepatis.
Clinical signs
Clinical features vary; refer to documentation. Patients may have nonspecific liver-related findings, and diagnosis is often confirmed by imaging or pathology.
When to use this code
Use K76.4 when the provider documents peliosis hepatis as the diagnosis, whether incidental or clinically significant. You may also use it when pathology or imaging clearly supports the condition and the note names it explicitly.
Do not substitute this code for generic liver lesions, hemorrhage, or unspecified hepatic abnormalities unless peliosis hepatis is stated. Check documentation if the wording is unclear or if the finding is only suspected.
Do not use for
Do not use this code for other vascular liver disorders, hepatic masses, or nonspecific liver cysts. If the chart does not name peliosis hepatis, check documentation.
Coding tip
Code K76.4 only when the diagnosis is explicitly documented; avoid inferring peliosis hepatis from imaging alone unless the provider confirms it.
