Insect bite (nonvenomous) of unspecified hand, sequela

This code indicates a long-term or late effect resulting from a nonvenomous insect bite on an unspecified hand. This could include residual scarring, chronic dermatitis, or persistent nerve damage that occurred after the initial bite healed.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past nonvenomous insect bite to the hand. This is used for follow-up care or when the sequela itself is the primary reason for the encounter, not the acute bite.

• Always sequence the sequela code first, followed by a code for the specific manifestation of the sequela (e.g., scar, dermatitis).
• Ensure documentation clearly links the current condition to a previous insect bite on the hand.
• Do not use this code for acute insect bites; use the appropriate acute injury code instead.
