Insect bite, nonvenomous of elbow, forearm, and wrist, without mention of infection

This code describes a skin lesion resulting from a nonvenomous insect bite located on the elbow, forearm, or wrist, where there is no documented evidence of secondary infection. It typically presents as localized erythema, pruritus, and mild swelling without purulence or fever.

Use this code when documentation clearly indicates a nonvenomous insect bite affecting the specified upper extremity regions. This applies to conditions like mosquito bites, flea bites, or ant bites that have not become infected. Documentation should explicitly state the anatomical site and absence of infection.

• Do not use if the bite is venomous (e.g., spider, scorpion); refer to codes for toxic effects.
• If infection is present, a more specific code from the 680-686 series (e.g., cellulitis, abscess) should be assigned in addition to or instead of this code.
• Ensure the documentation specifies the elbow, forearm, or wrist; other upper extremity sites would require a different code.
