Does It Make Sense to Have Two Health Insurance Plans?

Dual coverage means an individual is enrolled in two separate health policies simultaneously. When dual coverage exists, one plan is typically designated as the “primary” insurer, paying for covered medical expenses first. The other plan then acts as a “secondary” insurer, potentially covering remaining costs after the primary plan processes the claim. It is important to understand that having two plans does not mean an individual will receive double the benefits or that medical bills will be paid twice. Instead, the plans work together to ensure the total amount paid does not exceed the actual cost of services.

Common Scenarios for Multiple Health Insurance Plans

Individuals often have multiple health insurance plans due to various life circumstances. One scenario involves married couples where each spouse has an employer-sponsored plan and is also covered as a dependent on their partner’s plan. This arrangement can provide broader coverage options. Another situation occurs when a young adult, under age 26, is covered by their own employer’s or student health plan while remaining on a parent’s policy.

Dual coverage can also arise when an individual is eligible for both a private health insurance plan and a government program. For example, someone might have an employer-sponsored plan and also qualify for Medicare (if 65 or older) or Medicaid (due to income eligibility). Individuals transitioning between jobs might have COBRA continuation coverage from a former employer while enrolling in a new employer’s plan. Children of divorced parents may also have dual coverage, listed as dependents on both parents’ separate health insurance policies. In these situations, the goal is often to maximize coverage and minimize out-of-pocket expenses.

Understanding Coordination of Benefits

When an individual has two health insurance plans, the process that determines how the plans share the cost of medical care is called Coordination of Benefits (COB). COB rules prevent duplicate payments and ensure that the total reimbursement for services does not exceed 100% of the medical expenses. Under COB, one plan is designated as the primary payer, and the other is the secondary payer. The primary plan pays for services first according to its policy terms and limits.

After the primary insurer processes the claim, the secondary insurer reviews the remaining balance. The secondary plan may cover some or all remaining costs, such as deductibles, copayments, or coinsurance, depending on its specific terms and benefits. The secondary plan only pays what it would have covered if it were the primary plan. For example, if a primary plan covers 80% of a service, the secondary plan might cover the remaining 20%, significantly reducing the patient’s out-of-pocket expenses.

Determining which plan is primary follows specific rules. The plan covering an individual as an employee is primary over a dependent plan, such as a spouse’s or parent’s plan. For children covered by both parents’ plans, the “birthday rule” often applies; the plan of the parent whose birthday falls earlier in the calendar year is primary. If an individual has Medicare and an employer plan, the employer’s plan is primary if the employer has 20 or more employees; otherwise, Medicare may be primary. Medicaid is the payer of last resort, almost always secondary to any other health coverage.

Evaluating the Value of Additional Coverage

Evaluating additional health insurance coverage involves reviewing financial implications and potential benefits. A primary consideration is comparing combined premiums for both plans against potential reductions in out-of-pocket costs. While dual coverage can lead to lower deductibles, copayments, and coinsurance, the cost of two separate premiums might outweigh these savings, particularly if medical expenses are low. It is important to understand that even with two plans, some out-of-pocket costs may still remain.

Additional coverage may fill gaps in a primary plan. For example, if a primary plan has limitations on certain specialists, prescription drug coverage, or specific services, a secondary plan might offer broader access. Having two plans can also offer financial protection during significant medical events or chronic conditions, as the secondary plan can absorb costs after the primary plan’s benefits are exhausted.

Managing two health insurance plans can introduce administrative complexities. This includes navigating different provider networks, understanding varying coverage limits, and dealing with more paperwork and coordination between insurers. Inform both insurance providers about other coverage to ensure proper coordination of benefits and avoid claim delays or denials. Understanding how deductibles, copayments, and out-of-pocket maximums interact between the two plans is necessary to maximize their combined value.
