Insect bite (nonvenomous), left ankle, initial encounter

This code signifies a superficial injury to the left ankle resulting from a bite by a nonvenomous insect. This typically involves localized skin irritation, redness, swelling, or itching, without systemic effects or severe allergic reactions. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific injury.

Apply this code when documenting a patient presenting for the first time with symptoms directly attributable to a nonvenomous insect bite on their left ankle. This includes common bites from mosquitoes, fleas, or gnats. It is appropriate for initial evaluations and treatments such as topical creams or oral antihistamines.

• Ensure the documentation clearly specifies the left ankle as the affected site.
• Confirm the insect was nonvenomous; if venomous, a different code category would apply.
• Verify this is the patient's first visit for this specific bite; subsequent visits would use a different encounter character.
