Insect bite (nonvenomous) of breast, unsp breast, init

This diagnosis code signifies a nonvenomous insect bite affecting the breast area, without specifying which breast. It indicates the initial presentation of the patient for this particular injury.

This code is appropriate for documenting a patient's first visit for a localized reaction to a non-stinging insect bite on the breast. Examples include mosquito bites, ant bites (non-fire ant), or flea bites on the breast.

• Ensure the documentation explicitly states "nonvenomous" or implies it through the type of insect (e.g., mosquito).
• Confirm this is the patient's first encounter for this specific bite; subsequent encounters would use a different seventh character.
• If the laterality of the breast is documented (left or right), a more specific code should be selected.
