To locate an in-network provider, CLICK HERE. For help determining which network service area you are in, see the 2024 HSHS Benefits Guide. If you have a dependent that does not live in the Prevea360 service area, such as a child attending college, you can register your dependent with Dean Health Plan after you receive your Dean Health Plan ID card. Call Dean Health Plan to get started. Once your dependent is registered, the First Health network will apply for your dependent’s medical plan coverage.
