🎫 Why Some Doctors Require a Referral

The gatekeeping system that controls access to specialists.

What is a Referral?

  • A **referral** is a formal request from your primary care doctor for you to see a specialist.
  • This process ensures you receive care from the right expert for your condition.
  • Not all appointments require a referral, but many insurance plans, especially Health Maintenance Organizations (HMOs), require it to cover costs.
