Acute poliomyelitis (A80)

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.
