New Modifier 33

Thanks to Veronica Hodges for this update!

Note that Medicare has created HCPCS II codes for some

of these preventive medicine services. CPT modifier 33

is effective after January 1, 2011, and should be appended

to codes representing the preventive services, unless the

service is inherently preventive, eg, a screening mammography

or immunization recognized by the Advisory

Committee on Immunization Practices (ACIP).http://www.ama-assn.org/ama1/pub/upload/mm/362/new-cpt-modifier-for-preventive-services.pdf
