I do the billing for a Sleep Lab and a Pulmonary Clinic, The clinic see's the sleep pt's for the follow up visits after being put on the cpap or bipap machines, We have an out of state DME company that is telling our provider that we can bring the pt's into the clinic for downloads on the cpaps for tracking and can bill 94660 up to 4 times a year for each pt and that this can be done without the provider seeing the pt each time. I have tried finding documentation on this with no luck. Does anyone know if this is correct and anything I need to be aware of if I do this?
