5. Can a PT accept a referral from a physician outside the US?

Yes. The Board amended §321.1, Provision of Services, several years ago to allow a PT to accept a referral from a “qualified healthcare practitioner licensed by the appropriate licensing board.” The PT accepting the referral is responsible for ensuring that the practitioner is legally able to practice in that country, and legally authorized to write a referral for treatment in that country. This is no different than what is required if you accept a referral from a source in the U.S., but it does leave it up to the PT to determine the country’s requirements. See the Board rules, §322.1(a).
