Respiratory Question for the Week of May 1, 2017


When is it appropriate to report CPT code 94640?


The American Medical Association revised the description of CPT code 94640 in 2016 to clarify that this is a bundled code representing both diagnostic and therapeutic services and that it includes different treatment modes. It is appropriate to assign 94640 when documentation indicates the treatment is administered to a patient with an acute airway obstruction, and it may be reported for the induction of sputum for diagnostic purposes.
