I'm being told by my organization that a physician must use one of the functional G codes established by Medicare for therapy services when 92612 is used. This is confusing to me because he is not establishing a plan for therapy but using this as an evaluation of the patients swallowing. Is there some guidance published on the use of this code when it is not being used in therapy? Is the guidance correct that the provider must use a functional G code whenever he does one of these swallow studies?
