Does Medicare Cover Copays From Primary Insurance?

Medicare, a federal health insurance program, provides coverage for millions of Americans, primarily those aged 65 or older, certain younger people with disabilities, and individuals with End-Stage Renal Disease (ESRD). Many beneficiaries also possess other forms of health insurance, leading to questions about how these different coverages interact. A common inquiry arises concerning out-of-pocket expenses, such as copayments, and whether Medicare will cover these costs when another insurance acts as the primary payer.

Understanding Medicare’s Role in Coordination of Benefits

When an individual has multiple health insurance plans, a process called “Coordination of Benefits” (COB) determines which plan pays first. The plan that pays first is known as the “primary payer,” and the plan that pays after the primary is called the “secondary payer.” This process ensures that the total amount paid by all insurance plans does not exceed the total cost of the healthcare services received.

Medicare has specific rules for determining whether it acts as the primary or secondary payer, which are part of the Medicare Secondary Payer (MSP) program. These rules are designed to prevent Medicare from paying for services when another entity is primarily responsible. For instance, if an individual is aged 65 or older and covered by a group health plan (GHP) through current employment, Medicare is typically secondary if the employer has 20 or more employees. Conversely, if the employer has fewer than 20 employees, Medicare is usually the primary payer.

The primary insurer processes and pays its portion of the claim according to its policy terms. If a balance remains after the primary payer has paid, the claim is then sent to the secondary payer. The secondary payer, which could be Medicare, then reviews the claim to determine what additional costs it will cover. It is important for individuals to inform their healthcare providers about all their insurance coverages to ensure claims are submitted to the correct payers in the proper order.

When Medicare Acts as a Secondary Payer for Copays

When Medicare functions as the secondary payer, it can cover copayments, deductibles, or coinsurance amounts left over by the primary insurer. This occurs under the condition that the services are covered by Medicare, and the combined payment from both the primary insurer and Medicare does not exceed Medicare’s approved amount for that service. The Medicare-approved amount is the predetermined payment that Medicare considers reasonable for a service or item. Participating providers agree to accept this amount as full payment.

After the primary insurer processes a claim and pays its portion, the remaining balance, including any copay, is submitted to Medicare. Medicare then reviews the claim and the primary insurer’s payment. If the primary insurance paid less than the Medicare-approved amount, Medicare may cover the difference, which could include the copay. However, if the primary insurance pays an amount equal to or greater than the Medicare-approved amount, Medicare will not pay anything further, and there will be no remaining copay for Medicare to cover.

It is important to distinguish this from Medicare Supplement Insurance, also known as Medigap. Medigap policies are designed to cover Medicare’s deductibles, copayments, and coinsurance after Medicare has paid its share. Medigap plans pay after Medicare and do not act as a primary insurer. Medicare, as a secondary payer, directly addresses the remaining costs from a primary insurer, potentially including copays, up to the Medicare-approved amount.

Common Primary Insurance Scenarios

Employer Group Health Plans (EGHP)

Employer Group Health Plans (EGHP) represent a frequent coordination scenario. If an individual aged 65 or older is still working and has health coverage through an employer with 20 or more employees, the EGHP is typically the primary payer, and Medicare is secondary. The EGHP pays first, and Medicare may then cover remaining costs, including copays, up to its approved amount. For employers with fewer than 20 employees, Medicare usually serves as the primary payer.

COBRA Continuation Coverage

COBRA continuation coverage generally follows the same coordination rules as EGHPs. If an individual has Medicare and then becomes eligible for COBRA, Medicare is the primary payer, and COBRA is secondary. COBRA may then cover some or all of the costs not paid by Medicare, including copays, depending on its benefits. If COBRA was in effect before Medicare eligibility, the COBRA coverage often ends once Medicare begins, making timely Medicare enrollment crucial.

Retiree Health Plans

Retiree health plans are almost always secondary to Medicare. This means Medicare pays first for covered services, and the retiree plan then helps cover Medicare’s cost-sharing, such as deductibles, copayments, and coinsurance. Retiree plans can provide additional coverage for services Medicare does not cover, like vision or dental care.

TRICARE

TRICARE, the healthcare program for uniformed service members, retirees, and their families, also coordinates with Medicare. For those with TRICARE for Life (TFL), Medicare is generally the primary payer, and TFL acts as a secondary payer. TFL provides “wraparound coverage,” covering out-of-pocket costs in Original Medicare for TRICARE-covered services, including copays and deductibles.

Veterans Affairs (VA) Benefits

Veterans Affairs (VA) benefits operate differently; individuals must choose to receive care under either VA benefits or Medicare for each service. Medicare will not pay for services authorized by the VA, and similarly, VA coverage will not pay for services covered by Medicare. Therefore, copays incurred under VA care are typically covered by the VA, not Medicare, and vice versa.

Workers’ Compensation

Workers’ Compensation is always primary for work-related injuries or illnesses. Medicare will not pay for services that Workers’ Compensation is responsible for. If Workers’ Compensation denies coverage for a Medicare-covered service, or if payment is delayed, Medicare may make a conditional payment, which must be repaid once the Workers’ Compensation claim is settled. In such cases, Workers’ Compensation covers the copays related to the work injury.

No-Fault and Liability Insurance

No-fault and liability insurance, such as auto or homeowner’s insurance, are primary payers for accident-related care. Medicare is secondary in these situations. The no-fault or liability insurer pays first for services related to the accident or injury, and Medicare may then cover remaining costs if they are Medicare-covered services and the primary insurer has paid its share. If the primary insurer does not pay promptly, Medicare may make a conditional payment that must be reimbursed later.
