Now available: CPT Assistant on “Updated Endoscopic Nasal Sinus Surgery” codes

June 2018 – Vol. 37, No. 5

For the Current Procedural Terminology (CPT®) 2018 code set, significant changes were made to the Endoscopic Sinus Surgery (FESS) and Sinus Ostial Dilation (e.g., balloon sinus dilation or BSD) family of CPT codes. To help members understand the code changes and accurately report these procedures, the AAO-HNS partnered with the American Medical Association (AMA) to develop a CPT Assistant on the updated codes.

The CPT Assistant includes new introductory guidelines, updated full code descriptors of the bundled codes, details on revisions to the codes, helpful coding tips, and descriptions of all the procedures. Academy members can view the article via the AAO-HNS Coding Corner (, a member benefit providing access to the newest coding and reimbursement tools.

To access a full inventory of CPT Assistant articles, subscriptions to the AMA CPT Assistant newsletter can be purchased through the AMA’s online store at
