A80.0

What This Code Means

This is a rare paralysis caused by the polio virus that develops as a side effect from receiving the oral polio vaccine (OPV). The condition causes sudden weakness or inability to move muscles, typically in the legs, and occurs in vaccine recipients or their close contacts.

Coding Tips

• •This code is used only when polio paralysis is directly caused by the vaccine itself, not from wild-type polio infection; verify documentation clearly states vaccine-associated etiology
• •This is a reportable condition in most jurisdictions; ensure proper reporting to public health authorities and consider adding a code for the encounter reason (such as Z23 for encounter for immunization)
