ICD-10 Code A80.2 – Acute paralytic poliomyelitis, wild virus, indigenous (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A80.2 – Acute paralytic poliomyelitis, wild virus, indigenous
What it is
A80.2 identifies acute paralytic poliomyelitis caused by wild poliovirus, acquired domestically. It applies when the infection leads to paralysis, not just a nonparalytic poliovirus illness.
Clinical signs
Typical findings include acute flaccid weakness or paralysis, often asymmetric, with reduced reflexes. Clinical features vary; refer to documentation for confirmation of wild-virus infection and paralytic disease.
When to use this code
Use this code when the record documents paralytic poliomyelitis due to wild poliovirus and the infection is indigenous. You should have clear provider documentation of both the paralytic form and the wild-virus source.
Assign it for confirmed cases in which the patient’s illness is not described as vaccine-associated or post-polio syndrome. Check documentation if the chart only says “polio,” because that is not specific enough.
Do not use for
Do not use A80.2 for nonparalytic poliomyelitis, vaccine-associated cases, or post-polio sequelae. If the organism source or paralysis status is unclear, check documentation.
Coding tip
Verify the terms “paralytic,” “wild virus,” and “indigenous” in the note before assigning A80.2.
