Effective for claims processed on or after July 1, 2019, Highmark will be updating the reporting guidelines for bilateral services. This change is to more closely follow CMS bilateral rules and simplify billing practices for professional providers.
Keep in mind that there are several ways to report bilateral procedures. When reporting procedures that were performed bilaterally, you must report the correct number of services to correspond with the modifier(s) you report.
Special eBulletin dated March 29, 2019 has more information about these changes.
