Insect bite, nonvenomous of hip, thigh, leg, and ankle, infected

This code signifies an infection resulting from a nonvenomous insect bite located on the lower extremity, specifically the hip, thigh, leg, or ankle. The bite itself is not inherently dangerous, but secondary bacterial infection has developed at the site.

Apply this code when documentation clearly indicates a nonvenomous insect bite on the specified lower body regions, accompanied by signs and symptoms of infection (e.g., erythema, purulence, warmth, swelling). This is typically seen in cases of cellulitis or localized abscess formation secondary to an insect bite.

• Ensure the documentation specifies "nonvenomous" and clearly identifies the lower extremity location.
• Do not use for bites from venomous insects; those have distinct coding pathways.
• If a specific infectious organism is identified, sequence that code first, followed by this code.
