Common Procedure Terminology (CPT) codes are the primary means for describing and reporting services to public and private insurers in the US by physicians and other qualified providers for the patient care rendered. As the physician is ultimately responsible for the billing submitted under their name, it is essential to maintain an up-to-date knowledge of current CPT codes. The CPT codes are constantly undergoing revisions, with deletion of older codes, revisions and updates of existing codes, and the promulgation of new codes. This expert lecture is designed to provide all Otolaryngology practitioners an update of changes to CPT codes that are pertinent to the practice of otolaryngology.
