Seeing a specialist in Billings

  • Check the license with the Montana Board of Medical Examiners. Look up any physician on DocInfo.org.
  • HMO plans usually need a referral from your primary care doctor before a specialist visit; PPO plans usually do not.
  • Ask about the wait for a new-patient appointment and whether a cancellation list exists.
  • Send records and test results ahead of the visit so it is not spent repeating them.
