There is a local orthopedist who owns 7-8 PT practices in my area. When we perform an Initial Evaluation on one of his Medicare patients, he refuses to sign off on our plan of care (POC) even though we have his prescription. We will follow up multiple times with his front desk staff and even have the patients contact the referring MD office. The response is that these Medicare patients must be seen at his clinic/PT office. Is that correct?
