Modifier Lookup

Published 04/12/2022

The Palmetto GBA Modifier Lookup Tool provides guidelines for documenting and correctly submitting CPT and HCPCS modifiers on your claims. You may search the tool by modifier, keyword or phrase. All records matching your search criteria will be returned for your review. You may also use the “Show All” button to view a complete list of modifiers available.

If you are aware of a modifier that is not listed, or a description and/or a guideline that is not clear, please email Palmetto GBA ( with your suggestions.

Questions regarding individual claims must be directed to the Provider Contact Center. You may fax a Written Inquiry Request Form (PDF) to have your inquiry answered. Please do not include any Protected Health Information.
