ICD-10 Code A80.39 – Other acute paralytic poliomyelitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A80.39 – Other acute paralytic poliomyelitis
What it is
Use this code for an acute poliomyelitis infection with paralysis that is not classified elsewhere. It identifies a paralytic polio presentation documented as “other” rather than a more specific poliovirus type or manifestation.
Clinical signs
Clinical features vary; refer to documentation. Typical findings in paralytic poliomyelitis include sudden weakness, flaccid paralysis, and reduced muscle tone, sometimes with asymmetric involvement and diminished reflexes.
When to use this code
Use A80.39 when the record clearly states acute paralytic poliomyelitis and the provider does not specify a more exact poliomyelitis code. It is appropriate when the diagnosis is confirmed or documented as the reason for care. Check documentation if the note only says suspected polio or neurologic weakness without a confirmed paralytic poliomyelitis diagnosis.
Do not use for
Do not use this code for nonparalytic poliomyelitis, post-polio syndrome, or nonspecific viral illness. If the chart documents a different poliovirus manifestation, code that condition instead.
Coding tip
Confirm that “acute,” “paralytic,” and “other” are supported in the provider note before assigning A80.39.
