Insect bite (nonvenomous), unspecified great toe, sequela

This code signifies a long-term or residual effect stemming from a nonvenomous insect bite on an unspecified great toe. This means the acute injury has resolved, but the patient is still experiencing a related condition, such as scarring, chronic pain, or altered sensation, directly attributable to the original bite.

Apply this code when documenting a patient encounter for a sequela of a past nonvenomous insect bite affecting either great toe, where the specific toe is not documented. This is appropriate for follow-up visits addressing persistent issues like keloid formation, nerve damage, or chronic dermatitis resulting from the initial bite.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite on the great toe.
• Confirm the laterality of the great toe is truly unspecified in the medical record before selecting this code.
