Insect bite, nonvenomous, of other, multiple, and unspecified sites, without mention of infection

This code represents a non-venomous insect bite affecting multiple or unspecified body sites, where there is no documented evidence of infection. It describes the immediate, localized reaction to the bite, such as itching, redness, or swelling, without further complications.

Use this code when documentation specifies a non-venomous insect bite (e.g., mosquito, flea, ant) impacting various or unstated body areas. This code is appropriate when the medical record explicitly states "without infection" or when no signs or symptoms of infection are present.

• Do not use if the bite is from a venomous insect (e.g., spider, scorpion, wasp); refer to codes in the 989.5-989.8 range.
• If a localized infection (e.g., cellulitis, impetigo) is documented as a result of the bite, code the infection first, followed by this code.
• Avoid using this code if a more specific site of the bite is documented; look for codes that specify the anatomical location.
