Need help w/ Work Comp and PPD's and Impairment Ratings.
My question is, for cpt code 99455 is this only billable during a "physical" E/M, Does the W/C carrier have to have requested the PPD be done before it can be done. Example: the Dr. last see the W/C patient in Sept. then in Jan. the W/C carrier requested a PPD. The Dr gave the Impairment and PPD rating by reviewing his previous visit notes, (from sept) and other op reports and such. Can he charge the 99455 for the PPD without bringing the patient in for the exam? Can he base his PPD on an exam that was done before the W/C carrier requested the PPD? If he can not charge 99455 in this situation, can he charge for 99080-Special Reports and base his Impairment/PPD on the last visit? Any assistance would be appreciated!
