This webinar is a review of how to appropriately assign frequently misapplied CPT and HCPCS modifiers. Older modifiers and newly added modifiers, that were effective January 1, 2023, will be covered. This webinar is focused on modifiers that should be used on the facility side. While some of these modifiers can also be used on the professional side, this presentation does not focus on assigning modifiers on the professional side. For information regarding applying modifiers on the professional side, please see part one of this series- A Physician-Focused Guide to Applying Modifiers Correctly.
