If you have 2 patients scheduled for an hour at the same time, for example 8-9am (double booked), are you allowed to bill 4 timed units (60 min) to each patient? So patient A would get 4 units and patient B would also get 4 units.
From my understanding of AMA CPT codes if we are charging therapeutic procedures such as ther ex, ther act, gait, neuro re-ed, all of theses codes are supposed to be one-on-one. So I don't understand how some clinics are getting away with charging 4 timed units in an hour block for each patient. I know the clinics that are doing this are doing so with commercial payers and not federal payers.
Is there some loophole that I am not aware of because the CPT codes are written by AMA not CMS so they apply to both commercial and federal payers?
