Insect bite (nonvenomous), unspecified foot, sequela

This code signifies a long-term or late effect resulting from a nonvenomous insect bite on an unspecified part of the foot. It is used when the initial injury has healed, but residual symptoms, complications, or conditions directly attributable to the past bite are present. This could include persistent scarring, chronic dermatitis, or nerve damage.

Apply this code when documenting a patient encounter for a condition that is a direct consequence of a nonvenomous insect bite to the foot, and the original bite occurred in the past. Examples include a patient presenting with chronic itching or discoloration at the site of an old mosquito bite on their foot, or a scar revision surgery due to a prior insect bite.

• Always sequence this code after the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the foot.
• Avoid using this code for acute insect bites; use the appropriate acute injury code (e.g., S90.46-).
