When does group health insurance pay as the primary payer for individuals under the Medicare Secondary Payer rules?

• A. When an employee is self-employed
• B. When an employee is covered through family employment and the employer has more than 100 employees
• C. For all Medicare beneficiaries
• D. Only for government employees

Answer: (B)

Group health insurance pays as the primary payer under the Medicare Secondary Payer rules when the Medicare beneficiary is covered through an employer-sponsored plan. Specifically, if the employer has more than 100 employees, the group health plan typically assumes primary responsibility for claims before Medicare benefits are applied. This is especially true for individuals who are still actively employed and are covered by their employer's group plan.

In general, Medicare Secondary Payer rules outline scenarios where Medicare does not pay first. When a large employer (with more than 100 employees) provides coverage, they are considered primary, ensuring coverage for employees and their dependents before Medicare applies. This helps facilitate better access to health benefits for workers and their families.

In contrast, situations involving self-employment or small employers with fewer than 100 employees lead to different interactions between Medicare and group health plans. Similarly, whether individuals are government employees or general Medicare beneficiaries doesn't inherently dictate the primary payer status, as it is predominantly driven by the specifics of their employment coverage and the size of the employer.
