New Resources: Top 100 CPT Codes

March 2020 – Vol. 39, No. 2

The American Academy of Otolaryngology–Head and Neck Surgery has prepared new member resources outlining the Top 100 Current Procedural Terminology (CPT) codes reported by providers with the subspecialty designation of “4-Otolaryngology” within the Medicare enrollment database. Two charts are now available:

2020 Top 100 ENT Codes Billed in a Physician Office: the 100 most commonly reported codes in the physician office site of service.

2020 Top 100 ENT Codes Billed in the Hospital Outpatient Department: the 100 most frequently reported codes for the hospital outpatient site of service.

Volume for both charts is based on 2018 Medicare claims data, the most recent year for which data is available.

Further information and the chart files can be accessed as part of the Academy’s Coding Corner ( The Coding Corner is a valuable resource available to AAO-HNS members that includes CPT for ENT articles, annual code change summaries, and ICD-10 coding resources.
