There are key differences between being a rehabilitation agency and operating as a physical therapist private practice, such as differences in the Medicare-required supervision level of PTAs. You may have other business or financial reasons for becoming a rehabilitation agency, such as the ability to have expansion sites and broader geographic penetration for home and community-based services.
Regardless, it is important to keep in mind that the process of becoming and remaining a rehabilitation agency under Medicare takes time and resources. Before you pursue this process, be sure you fully understand the requirements associated with such a move.
