Doctors of Chiropractic are portal-of-entry providers, like dentists. You don’t need permission or a referral to see one. Some insurance companies use a gatekeeper—a person or entity that limits different types of care. On a few plans, the insurance company may require a referral, but this is not common and has only to do with billing. That’s why it’s always a good idea to check with your insurance first to make sure of your benefits for chiropractic services.
