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

This code signifies a lasting or residual effect from a nonvenomous insect bite that occurred on an unspecified breast. It indicates that the acute phase of the bite has passed, but the patient is still experiencing a related condition, such as scarring, chronic dermatitis, or persistent itching.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a past nonvenomous insect bite to the breast. This applies when the original bite is no longer active but has left a sequela requiring ongoing management.

• Always use a seventh character of "S" for sequela when the residual effect of the bite is being treated.
• Ensure documentation clearly links the current breast condition to a previous nonvenomous insect bite.
• Code the specific sequela (e.g., L90.5 for scar conditions) in addition to this code, if applicable.
