What This Code Means
A80.30 is the ICD-10-CM diagnosis code for acute paralytic poliomyelitis, unspecified. This code describes a serious viral infection caused by poliovirus that results in sudden paralysis, but the specific type or location of paralysis is not specified. It is an acute condition requiring immediate medical attention. A80.30 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).
A80.30 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 specifies acute paralytic poliomyelitis rather than non-paralytic form; if paralysis location is documented (bulbar, spinal, etc.), use more specific A80.31-A80.39 codes instead.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A80.30 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies acute paralytic poliomyelitis rather than non-paralytic form; if paralysis location is documented (bulbar, spinal, etc.), use more specific A80.31-A80.39 codes instead
- •Confirm the poliovirus type (wild-type, vaccine-derived, or unspecified) is documented, as this may affect code selection and public health reporting requirements
