An employer's group medical insurance policy, issued as a single contract, is known as a

• A. Master policy
• B. Group endorsement
• C. Rider
• D. Master contract

Answer: (D)

In group health plans, coverage for everyone in the group is bundled under a single agreement between the insurer and the employer. This one document sets the plan’s terms, benefits, eligibility, and payment details for the whole group. That single agreement is known as the master contract (often called the master policy in many texts). Employees get individual certificates that reference this master contract, but they aren’t separate contracts themselves.

Riders or endorsements are used to modify or add to an existing contract, not to serve as the primary agreement covering the entire group. So the best term for a group medical insurance policy issued as one contract is the master contract.
