If you are evacuated, you may not have to get a referral from your primary care manager to see a TRICARE authorized provider. This is also known as a blanket referral waiver. This applies to anyone in a TRICARE Prime plan in certain counties in Florida. A list of affected counties is on the TRICARE website. This waiver is good until January 15, 2019. This includes active duty servicemembers using urgent care.
