Insect bite (nonvenomous) of left forearm, sequela

This code signifies a lasting effect or complication stemming from a nonvenomous insect bite on the patient's left forearm. This could include chronic scarring, persistent discoloration, nerve damage, or other long-term issues that developed as a direct result of the original bite. It indicates that the acute phase of the bite has passed, and the current encounter addresses a residual problem.

Use this code when documenting a patient presenting with a chronic condition or permanent change to their left forearm that is directly attributable to a past nonvenomous insect bite. This would apply to follow-up visits for scar revision, management of chronic pain or paresthesia, or treatment of persistent skin changes in the area of the old bite. It should be used when the original bite is no longer an active injury but has left a sequela.

• Always use this code as a secondary diagnosis, with the primary diagnosis describing the specific nature of the sequela (e.g., scar, dermatitis).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite on the left forearm.
• Verify the "S" seventh character is appropriate for a sequela, indicating a complication or condition that is the result of a previous injury or disease.
