Insect bite (nonvenomous) of left thumb, sequela

This code indicates a long-term or late-effect condition resulting from a nonvenomous insect bite on the left thumb. This could include persistent scarring, chronic dermatitis, nerve damage, or other lasting complications directly attributable to the original bite. It signifies that the acute phase of the bite has passed, and the patient is now experiencing a residual issue.

Apply this code when documenting a patient presenting with a current sequela directly linked to a past nonvenomous insect bite on their left thumb. This would be appropriate for follow-up visits addressing chronic pain, disfigurement, or functional impairment that developed after the initial bite healed. It should be used when the primary reason for the encounter is the management of this lasting effect.

• Always sequence the sequela code first, followed by a code identifying the specific nature of the sequela (e.g., scar, dermatitis).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the left thumb.
• Do not use this code for acute insect bites; those require codes from the initial encounter or subsequent encounter categories.
