ICD-10 Code K73.2 – Chronic active hepatitis, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K73.2 – Chronic active hepatitis, not elsewhere classified
What it is
K73.2 identifies chronic active hepatitis that is not classified elsewhere. Use it for ongoing liver inflammation documented as active and chronic when a more specific cause or type is not stated.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe persistent hepatitis with evidence of active hepatic inflammation, but the chart should support chronic disease rather than an acute, resolved, or unspecified liver condition.
When to use this code
Use K73.2 when the provider documents chronic active hepatitis and does not assign a more specific etiology or subtype. It fits cases where the condition is clearly chronic and active, but the record does not support a different chronic hepatitis code.
Check documentation if the note mentions autoimmune, viral, toxic, or other specific hepatitis causes. Code the more specific diagnosis when stated.
Do not use for
Do not use this code for acute hepatitis, inactive chronic hepatitis, or hepatitis with a clearly identified cause that has its own code. If the documentation is vague, check documentation.
Coding tip
Confirm that both “chronic” and “active” are documented before assigning K73.2.
