A group health insurance plan is a health insurance plan that provides coverage to members of a group that tends to be employees of a company or members of an organization. Members of the group usually receive insurance at a reduced cost because the insurer’s risk is spread across a group of policyholders.

The primary advantage of a group plan is that it spreads risk across a pool of insured individuals. This benefits the group members by keeping premiums low, and insurers can better manage risk when they have a clearer idea of who they are covering.
