Insect bite (nonvenomous) of oral cavity, initial encounter

This code signifies a non-toxic insect bite affecting the mucous membranes or other structures within the mouth. It specifically indicates the initial presentation or active treatment phase of such an injury. This condition typically involves localized inflammation, pain, or irritation from the insect's bite.

Apply this code when documentation clearly states a patient presents with an insect bite to the oral cavity, and the bite is explicitly noted as nonvenomous. This is appropriate for the first encounter for treatment of the bite, such as initial examination, symptom management, or prescription of medication. Supporting documentation includes physician notes detailing the location, cause (insect bite), and nonvenomous nature.

• Ensure the documentation specifies "nonvenomous" to differentiate from bites requiring antitoxin or more severe treatment.
• Verify the bite location is specifically within the oral cavity (e.g., tongue, buccal mucosa, palate).
• Confirm this is the "initial encounter" for treatment; subsequent encounters would use a different seventh character.
