Buddy Documentation Tip

HCC Buddy guidance
Sylvatic rabies (A82.0) should be used when the rabies exposure is documented as coming from a wild animal source; if the animal source is unknown or domestic, use different rabies codes (A82.1 for urban rabies or A82.9 for unspecified)
Always document the specific wild animal exposure when possible, as this information supports medical necessity and may be required for public health reporting and epidemiological tracking

Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.

What This Code Means

A82.0 is the ICD-10-CM diagnosis code for sylvatic rabies. Sylvatic rabies is a form of rabies infection transmitted from wild animals (such as bats, raccoons, or skunks) to humans. This type of rabies occurs in natural wildlife populations rather than in domestic animals. A82.0 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).

A82.0 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.

Sylvatic rabies (A82.0) should be used when the rabies exposure is documented as coming from a wild animal source; if the animal source is unknown or domestic, use different rabies codes (A82.1 for urban rabies or A82.9 for unspecified).

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A82.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Sylvatic rabies (A82.0) should be used when the rabies exposure is documented as coming from a wild animal source; if the animal source is unknown or domestic, use different rabies codes (A82.1 for urban rabies or A82.9 for unspecified)
  • Always document the specific wild animal exposure when possible, as this information supports medical necessity and may be required for public health reporting and epidemiological tracking
