Insect bite (nonvenomous) of right upper arm, sequela

This code indicates a lasting effect or complication resulting from a nonvenomous insect bite on the patient's right upper arm. This could include chronic scarring, persistent discoloration, nerve damage, or other long-term issues that developed after the initial bite healed. The sequela represents the current problem stemming from the past injury.

Use this code when documenting a patient presenting with a current condition directly attributable to a nonvenomous insect bite that occurred previously on their right upper arm. This applies when the acute phase of the bite has passed, and the current encounter is for the management of the residual effects. Examples include treating a keloid scar from an old mosquito bite or managing chronic pruritus at the site of a healed ant bite.

• Always ensure documentation clearly links the current condition to the past insect bite on the right upper arm.
• This code is for the sequela (late effect), not the initial acute bite.
• Consider additional codes for specific manifestations of the sequela (e.g., L90.5 for scar conditions).
