The Certificate of Insurance (COI) is a document issued by Health Net Life Insurance Company to employees insured under a group insurance policy, which describes the covered services, supplies and exclusions and limitations that apply to the benefits for which the employee and their insured dependents are eligible. COIs are available to members on the member portal at www.healthnet.com, or in hard copy on request. Providers may obtain a copy of a member's COI by requesting it from the Health Net Provider Services Center. COIs apply to Health Net Life, PPO, EPO and Flex Net plans.
