What This Code Means
A82.1 is the ICD-10-CM diagnosis code for urban rabies. Urban rabies is a viral infection transmitted through contact with infected animals (typically dogs, cats, or bats) in populated areas. This serious disease affects the nervous system and is almost always fatal once symptoms appear. A82.1 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering viral and prion infections of the central nervous system (a80-a89).
A82.1 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Urban rabies (A82.1) is used when rabies is contracted in urban/city settings; differentiate from A82.0 (sylvatic/wild rabies) based on the exposure location and animal type involved.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A82.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Urban rabies (A82.1) is used when rabies is contracted in urban/city settings; differentiate from A82.0 (sylvatic/wild rabies) based on the exposure location and animal type involved
- •Always document the type of animal exposure and date of bite/exposure in the medical record, as this information supports medical necessity and may affect treatment protocols and public health reporting requirements
