Code Description

ICD-10 A82 is a billable code used to indicate a diagnosis of rabies.

Key Diagnostic Point:

Rabies is a viral infection caused by the rabies virus, which is a member of the Lyssavirus genus. It primarily affects mammals, including humans, and is transmitted through the saliva of infected animals, typically via bites. The virus travels along peripheral nerves to the central nervous system (CNS), leading to severe neurological complications. Initial symptoms may include fever, headache, and malaise, which can progress to more severe manifestations such as hydrophobia, paralysis, and ultimately, coma and death if left untreated. The incubation period can vary, but symptoms usually appear within one to three months after exposure. Vaccination is crucial for prevention, especially for individuals at high risk, such as veterinarians and animal handlers. Post-exposure prophylaxis (PEP) with rabies vaccine and rabies immune globulin is effective if administered promptly after exposure. Accurate coding of rabies is essential for proper treatment and public health reporting, as it is a notifiable disease in many jurisdictions.
