Insect bite (nonvenomous) of unspecified ear, init encntr

This code signifies a non-poisonous insect bite located on an unspecified part of the ear. It indicates the initial treatment or evaluation of the injury. This typically involves localized skin irritation, redness, and itching caused by the insect.

Apply this code when a patient presents for the first time with symptoms of a nonvenomous insect bite to the ear, such as from a mosquito, ant, or fly. Documentation should clearly state the location as the ear, confirm the nonvenomous nature of the bite, and indicate that this is the initial encounter for this specific injury.

• Ensure documentation specifies "nonvenomous" to differentiate from venomous bites (e.g., spider, scorpion).
• Verify the encounter is indeed the "initial" one; subsequent care would use a different encounter character.
• If the specific ear (left or right) is documented, use the more specific code (S00.461A or S00.462A).
