ICD-10 Code A82.9 – Rabies, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A82.9 – Rabies, unspecified
What it is
A82.9 identifies rabies when the record confirms the disease but does not specify a type or laterality. Use it for a documented rabies infection without further detail.
Clinical signs
Rabies is a severe viral encephalitis. Clinical features vary; refer to documentation, but common findings include agitation, hydrophobia, aerophobia, confusion, and progressive neurologic decline.
When to use this code
Use A82.9 when the provider documents rabies and no additional qualifying detail is recorded. It may apply after exposure evaluation, when the diagnosis is confirmed, or when the chart simply states “rabies” without subtype information.
If the note identifies a more specific rabies form or a related complication, code that documented condition instead. You should not infer details that are not stated.
Do not use for
Do not use A82.9 for rabies exposure, observation after exposure, or prophylaxis without a confirmed diagnosis. Check documentation if the record only mentions an animal bite or suspected exposure.
Coding tip
Code the confirmed diagnosis only; if the provider does not clearly document rabies, query for clarification rather than assuming infection.
