Do I need a referral to make an appointment?

It depends on what kind of insurance you have. If you have an HMO, you must:

  • Get a referral from your child's primary care physician before you call to make an appointment.
  • Make sure your referral has not expired. Many are good for only 30 days, so check yours before you come to your appointment. If your referral has expired, call your primary care physician and explain your situation. In most cases, your primary care physician will provide a new or extended referral.
  • Bring the referral with you to the appointment. If you do not have a referral, or if the referral you have is expired, your HMO will not pay for your appointment.
  • If you have fee-for-service insurance or a PPO, you do not need a physician's referral to make an appointment.

We offer in-depth information about insurance in our Billing and Insurance section.
