Insect bite, nonvenomous of shoulder and upper arm, infected

This code signifies an infection resulting from a nonvenomous insect bite located on the shoulder or upper arm. The bite itself is not inherently toxic, but secondary bacterial colonization or other infectious processes have developed at the site.

Apply this code when documentation clearly indicates a nonvenomous insect bite on the shoulder or upper arm that has subsequently become infected. This is appropriate for conditions like cellulitis, impetigo, or abscess formation directly attributable to the bite.

• Ensure the documentation specifies "nonvenomous" to differentiate from bites requiring different coding.
• Verify the anatomical site is explicitly the shoulder or upper arm; other locations have distinct codes.
• Do not use this code if the bite is venomous or if the infection is unrelated to the bite itself.
