No. You do not need a referral from a physician to receive physical therapy services in the state of California.
If you continue to need physical therapy services 45 days after your evaluation (or for more than 12 visits), we will need a physician to sign-off on your plan of care. Don't worry, we'll help with this process.
If at any time over the course of your treatment your therapist feels further medical examination or treatment is indicated, we will encourage you to visit your physician or refer you to an appropriate provider.
