Insect bite, nonvenomous, of hip, thigh, leg, and ankle, without mention of infection

This code signifies a localized skin reaction resulting from a bite by a nonvenomous insect, specifically affecting the hip, thigh, leg, or ankle. It describes the acute, non-infected dermatological manifestation of such an exposure.

Apply this code when documentation clearly indicates a nonvenomous insect bite on the lower extremity (hip, thigh, leg, or ankle) without any signs or symptoms of secondary infection. This is appropriate for conditions like mosquito bites, flea bites, or chigger bites presenting as localized erythema, pruritus, or papules.

• Ensure the documentation explicitly states "nonvenomous" or implies it through the absence of venom-related symptoms.
• Do not use if there is any mention of infection (e.g., cellulitis, abscess); a different code would be required.
• Verify the anatomical site is clearly specified as hip, thigh, leg, or ankle to differentiate from bites on other body regions.
