Insect bite (nonvenomous), unspecified ankle, sequela

This code indicates a long-term or late effect resulting from a nonvenomous insect bite on an unspecified ankle. This could include residual scarring, chronic dermatitis, or persistent itching that occurs after the initial acute phase of the bite has resolved. The "sequela" designation signifies that the current condition is a direct consequence of a past insect bite.

Apply this code when documenting a patient presenting with a chronic condition directly attributable to a nonvenomous insect bite on an ankle, where the specific ankle (right or left) is not documented. This is appropriate for follow-up visits addressing lasting effects rather than the acute bite itself.

• Always sequence the sequela code first, followed by a code for the specific manifestation of the sequela (e.g., scar, chronic dermatitis).
• Ensure documentation clearly links the current ankle condition to a previous insect bite.
• Avoid using this code for acute insect bites; instead, use the appropriate acute bite code.
