Insect bite, nonvenomous, of other, multiple, and unspecified sites, infected

This code signifies a bacterial infection resulting from a nonvenomous insect bite affecting multiple or unspecified body sites. The primary injury is an insect bite, but the significant clinical finding is the subsequent localized infection, such as cellulitis or impetigo, at the bite site(s).

Apply this code when documentation clearly indicates a nonvenomous insect bite that has become secondarily infected. This is appropriate for patients presenting with erythema, warmth, pain, or purulent discharge at the site of insect bites, where the specific body site is not documented or multiple sites are involved.

• Ensure documentation specifies "infected" to justify this code; otherwise, a non-infected bite code is more appropriate.
• If a specific body site is documented (e.g., arm, leg), use a more specific code from the 919.x series if available.
• Do not use for bites from venomous insects (e.g., spiders, scorpions); those have distinct coding pathways.
