Insect bite (nonvenomous) of unspecified hand, init encntr

This code signifies a superficial skin injury on an unspecified hand resulting from a bite by a non-venomous insect. It indicates the initial treatment or evaluation of the injury, which typically presents as localized redness, swelling, and itching without systemic effects.

Use this code for patients presenting with an insect bite on the hand where the specific hand (left or right) is not documented, and the insect is known or presumed to be non-venomous. This applies to the first time the patient is seen for this particular injury.

• Ensure documentation specifies "unspecified hand" if laterality is not clear.
• Confirm the insect is non-venomous; otherwise, a different code for venomous bites would be appropriate.
• The "A" in the seventh character indicates an initial encounter for this condition. Subsequent encounters would require a different seventh character.
