ICD-10 Code A82 – Rabies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A82 – Rabies
What it is
A82 identifies rabies, a viral infection that affects the central nervous system and is usually transmitted through the bite or saliva exposure of an infected animal. It is a serious diagnosis requiring prompt clinical attention.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include fever, headache, anxiety, agitation, hydrophobia, and progressive neurologic dysfunction.
When to use this code
Use A82 when the provider documents rabies as the confirmed diagnosis. It may apply after animal exposure when the clinical record supports active infection or suspected rabies being treated as such. If the chart only documents exposure or post-exposure prophylaxis, check documentation before coding A82.
Do not use for
Do not use A82 for animal bite exposure without rabies infection. Also avoid it when the record only shows vaccination, prophylaxis, or observation after exposure.
Coding tip
Code A82 only when rabies is explicitly documented; otherwise, verify whether the encounter is for exposure, prophylaxis, or another neurologic condition.
