Acute poliomyelitis (A80) ICD-10-CM
The A80 code range covers acute poliomyelitis with 9 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Poliomyelitis
An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5)
About the A80 Code Range
Acute poliomyelitis is an infection caused by poliovirus that may affect the spinal cord and lead to paralysis.
A80 separates paralytic disease from nonparalytic disease and poliomyelitis without a specified form. The paralytic codes distinguish vaccine-associated disease (A80.0), imported wild virus (A80.1), and indigenous wild virus (A80.2). The other and unspecified paralytic branch (A80.3) splits into unspecified (A80.30) and other (A80.39). Separate codes identify nonparalytic disease (A80.4) and acute poliomyelitis without a specified form (A80.9).

What does the A80 range classify?
The range classifies acute poliomyelitis. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
