When a Medicare Cost Plan is the secondary payer to an employer group health plan, the
coordination of benefits occurs in the aggregate through the cost report process. This
process results in a copayment as part of the Medicare cost plan benefit package for
which every enrollee is liable. Therefore, there is no coordination of benefits on a
beneficiary-specific basis that would relieve an enrollee with employer group health plan
coverage of his or her cost sharing obligation under the Medicare cost plan. As a result,
the enrollee remains liable for payment of the Medicare cost plan’s cost sharing
regardless of whether Medicare is primary or secondary. However, under 42 CFR
417.454, which addresses beneficiary financial protection contained in the contract
between the Medicare cost plan and CMS, the Medicare cost plan is responsible for
relieving the beneficiary of responsibility for payment of health care costs other than cost
sharing, and therefore, the Medicare cost plan must relieve the enrollee of his or her
liability under the terms of the employer group health plan.
For example, if the employer group health plan (the primary payer) has a copayment of
$20 and the Medicare cost plan has a copayment of $10 for the service the beneficiary
received, the beneficiary cannot be liable to pay more than the plan copayment of $10.
The Medicare cost plan must absolve the beneficiary of the liability for any amount in
excess of the plan copayment of $10.
