What This Code Means
A80.39 is the ICD-10-CM diagnosis code for other acute paralytic poliomyelitis. This code describes a case of poliomyelitis (a viral infection affecting the nervous system) that causes sudden paralysis, but doesn't fit into the more common types. Poliomyelitis is a serious infectious disease that can cause permanent muscle weakness or paralysis. A80.39 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).
A80.39 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.
Use this code only when the poliomyelitis is acute (sudden onset) and causes paralysis, and the specific type doesn't match A80.0, A80.1, or A80.2.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A80.39 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
