ICD-10 Code A80.30 – Acute paralytic poliomyelitis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A80.30 – Acute paralytic poliomyelitis, unspecified
What it is
This code identifies an acute poliovirus infection that causes paralysis, without documentation of a specific paralytic form or type. Use it when the record confirms acute paralytic poliomyelitis but does not specify further detail.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include acute flaccid weakness, reduced reflexes, and asymmetric paralysis consistent with poliomyelitis.
When to use this code
Use A80.30 when the provider documents acute paralytic poliomyelitis and does not name a more specific paralytic category. It is appropriate when the diagnosis is confirmed clinically or by documentation in the medical record. If the note only mentions poliovirus exposure or nonparalytic illness, check documentation.
Do not use for
Do not use this code for nonparalytic poliomyelitis or for a history of polio without current paralysis. If the record specifies a different paralytic form, code that documented condition instead.
Coding tip
Code from the provider’s exact wording and avoid assuming paralysis when the record does not clearly document it.
