When it’s an emergency

If you have an emergency, follow the steps below.

1. Go to the nearest emergency room

  • If you can, go to the hospital ED closest to you right away.

  • If you cannot get there right away, or if it is not safe to move the victim, or take yourself, call 911 or your police emergency number.

2. Call your primary care doctor after the emergency care

  • Tell your doctor about the emergency. Call within 24 hours of going to the ER.

  • If you can't call, have someone call for you.

  • Go to your doctor (not the ER) for any follow-up care.

When it’s not an emergency

If a problem is not an emergency, follow these steps:

1. Call your primary care doctor

  • If you don’t know the name of your doctor, call your health plan.

  • If you can't call, have someone call for you.

2. Follow instructions

  • Your doctor will tell you what you should do.

  • You may be told to see your doctor right away. You may be told to go to the ER. Or you may be told to go to an urgent care center.

  • Follow your doctor’s advice.
