Your PCP will tell you when you and/or your child need to see a specialist. Your PCP will make sure that you and/or your child get the special care needed. Most of the time, you cannot go to another doctor or get a special service if your PCP does not agree to make a referral. A referral is when your PCP sends you to another doctor. You should expect the specialist to give you an appointment within 30 days for non-urgent care or within 24 hours for urgent care.
