• You and your eligible dependents must enroll in the same plan and you must also live or work within the Trio HMO service area. Visit for a listing of the Trio service areas.

• You must choose a primary care physician (PCP) for yourself and your covered dependents. Each member of your family can choose a different physician and medical group.
