1 For patients not covered by health insurance, physical therapy typically costs $50-$350 or more per session, depending on the length of the session, the service provided during the session and the provider. Many providers offer discounted packages. 2  For example, Joint Ventures Physical Therapy and Fitness in Massachusetts charges $70 for a half-hour session and $105 for an hour-long session, but offers packages that take $10 off the cost of each session.
