ECOH is a medical provider network and is not involved in determining eligibility or benefit levels. To confirm your eligibility and to determine what services are covered and at what levels, you will need to contact your Third Party Administrator or insurance company.

Phone number and/or web address information for your Third Party Administrator or insurance company, Prescription Benefit Manager, Out-of-Area Network, and pre-certification information are found on your health plan ID card.
