The AT Modifier is used to indicate that the covered services billed are for active corrective treatment and the provider’s documentation supports medical necessity and Medicare coverage guidelines. The GA, GX, GY and GZ modifiers can also be used to indicate services that are expected to be denied because of lack of medical necessity or statutory exclusion, and those that do not meet the definition of any Medicare benefit.
