ICD-10 Code G14 – Postpolio syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G14 – Postpolio syndrome
What it is
G14 identifies postpolio syndrome, a late complication that can appear years after recovery from paralytic poliomyelitis. It reflects new or worsening weakness and related problems in a person with a prior polio history.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include progressive muscle weakness, fatigue, muscle pain, and reduced endurance in previously affected or unaffected muscles.
When to use this code
Use G14 when the provider documents postpolio syndrome or post-polio sequelae as the diagnosis being treated or evaluated. You may also use it when the chart clearly links current neuromuscular decline to prior poliomyelitis. Confirm that the record supports a late effect rather than active infection.
Do not use for
Do not use this code for acute poliomyelitis or for weakness without documentation tying it to prior polio. Check documentation if the chart only mentions a history of polio without current postpolio syndrome.
Coding tip
Query the provider if the record says “post-polio weakness” but does not explicitly state postpolio syndrome or a sequela relationship.
