As of January 2015, all 50 states, the District of Columbia, and the U.S. Virgin Islands allow patients to seek some level of treatment from a licensed physical therapist without a prescription or referral from a physician or other healthcare provider.
However, if you plan to use your out-of-network health insurance coverage to partially reimburse the cost of Yes! care, you should check with your insurance company first, because some insurers still require a prescription in order to reimburse you.
