I keep hearing about new modifier QQ. What is this modifier used for, and is its use mandatory?
Here’s the full description of modifier QQ: Ordering professional consulted a qualified clinical decision support mechanism (CDSM) for this service and the related data was provided to the furnishing professional. Modifier QQ will be used on Medicare claims for advanced diagnostic services when the ordering physician consulted a qualified CDSM such as the American College of Radiology’s appropriate use criteria.
The use of modifier QQ is voluntary beginning July 1, 2018 and can be added to the same claim line as the CPT® code for the diagnostic service when the furnishing professional is aware of the result of the ordering professional’s consultation with a CDSM for that patient. The modifier should be reported on both the facility and professional claim.
