I think you're going to want to look at the non-facility rates, which aren't much higher, but range from about $97 to $143 per unit.
If there were more freedom involved in terms of schedule requirements (e.g., if it were more easily integrated into an existing full-time schedule, such as providing a couple hours in the evening a few times per week or on the weekend), I could see why folks might consider taking less than Medicare rates, given the paid no shows/cancellations policy (although I would want to get in writing that the pay for a no show/cancellation is in fact the same as a patient/client hour rather than some reduced amount). But they're asking for a minimum of 30 hours/3 days a week in most positions, requiring some on-site training for a couple weeks in most locations, and dictating that appointments must be M-F and, what looks to me at least, sometime between 08:00 and 17:00. So I don't know if I'd be very drawn to it. But I see the appeal in terms of basically walking into a readymade telehealth clinical setup that you could do in addition to other work while making, if my math is correct, around $1900/week (assuming 7 clients/day, 3 days/week). Although as a 1099, you may only take home like 60% of that, depending on state tax rates, your tax bracket, etc. Caveat--I don't have a therapy practice, so don't know how that would compare to what folks could do on their own.
