The CPT code for the destruction by laser of premalignant actinic keratosis lesions is 17110 for the first 14 lesions treated. Since you are treating three lesions, you would use this code, as it covers the destruction of multiple lesions in a single session. If more than 14 lesions were treated in a single session, additional codes may apply. Always verify with the latest coding guidelines and payer policies for accuracy.
You could use CPT code 40812, which is for an excision or the destruction of a vestibule of the mouth.
