A80.9

What This Code Means

This code describes a sudden viral infection that affects the nerve cells controlling muscles, causing weakness or paralysis, but the specific type or location of the infection is not specified. It's a serious condition that can affect the ability to move and breathe.

Coding Tips

• •Use this code only when the specific type of poliomyelitis (bulbar, non-paralytic, or paralytic) cannot be determined from the medical record; if the type is documented, use the more specific A80.0-A80.3 codes instead
• •This is a reportable disease in most jurisdictions; ensure proper documentation of the acute onset and clinical presentation to support medical necessity and compliance with public health requirements
