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 2026, 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.

About the A80 Code Range
The ICD-10 code section A80 covers acute poliomyelitis, which includes various types of this viral infection affecting the nervous system. These codes are essential for identifying different forms of polio, such as vaccine-associated, wild virus (imported or indigenous), paralytic, and nonparalytic cases.
The ICD-10 code for acute poliomyelitis ranges from A80.0 to A80.9, distinguishing specific conditions. For instance, A80.0 refers to acute paralytic poliomyelitis related to vaccination, while A80.1 and A80.2 specify wild virus infections imported or indigenous. Codes like A80.3 and A80.30 cover unspecified paralytic poliomyelitis, also known as infantile paralysis or bulbar poliomyelitis. The section includes nonparalytic forms (A80.4), also called abortive poliomyelitis. Finally, A80.9 covers acute poliomyelitis when unspecified, which can relate to complications such as polioencephalitis or neuromuscular scoliosis. Medical coders use these codes to precisely document the type and origin of poliomyelitis in patient records, supporting accurate diagnosis and treatment tracking.
