What This Code Means
A80.1 is the ICD-10-CM diagnosis code for acute paralytic poliomyelitis, wild virus, imported. This is a serious infection caused by the wild polio virus that has been brought into a country from another location, resulting in sudden paralysis. It is a rare condition in countries with polio vaccination programs. A80.1 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).
A80.1 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.
Verify documentation clearly states the virus is wild-type (not vaccine-derived) and that the case was imported from another country to support accurate code selection.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A80.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation clearly states the virus is wild-type (not vaccine-derived) and that the case was imported from another country to support accurate code selection
- •This code requires a seventh character extension to specify the site of paralysis (e.g., A80.11 for bulbar involvement, A80.12 for other sites); ensure complete documentation of affected body regions
