In the United States, it is legal to have two health insurance plans, and it is becoming increasingly common to do so. In 2021, about 43 million people (13%) had multiple health plans. There are several scenarios in which someone might have or need two health insurance plans, such as being married and having an employer-sponsored group health plan while also being on a spouse's plan, or being a student with a university medical plan while also being on a parent's health policy. However, it is important to understand the difference between primary and secondary insurance before securing two health plans. The primary plan is the main insurance policy that will cover medical care first, while the secondary plan will only kick in after the primary insurance reaches its coverage limits.

What You'll Learn

It is legal to have two health insurance plans
It is perfectly legal to have two health insurance plans, and many people do. This is known as dual coverage, and it can be beneficial in many situations. For example, if you are married, you and your spouse may have separate insurance plans from your respective workplaces. In this case, you would be covered by your plan and as your spouse's dependent. Similarly, a student younger than 26 may have a university medical plan while still being covered by their parents' insurance. Children of divorced parents may also have separate insurance from each parent. If you qualify for Medicaid, it can supplement your coverage if you have another insurance plan.
However, it is important to understand the difference between primary and secondary insurance before securing two health plans. Your primary plan is your main insurance policy and will cover your medical care first. For instance, if you visit the doctor or need prescription drugs, your primary insurer will cover the bills up to its coverage limits. You may also owe cost-sharing fees, such as copayments or coinsurance, and you will likely have an annual deductible and an out-of-pocket maximum. Your secondary insurance plan will only kick in after your primary insurance reaches its coverage limits. If there are any remaining costs, your secondary insurance will cover them, depending on its coverage limits.
Having dual coverage can offer more comprehensive coverage and greater protection from loss of coverage. For example, if you have coverage through your parents' or spouse's plan and a company plan, you don't have to worry about losing health insurance if you lose your job. Additionally, if one of your policies lapses, you will not have a gap in coverage as your second plan will automatically cover you. Furthermore, if your two plans are complementary, you may gain access to more benefits.
However, there are also potential downsides to having dual coverage. You will still be responsible for both plans' monthly premiums and applicable cost-sharing under plan rules. These extra out-of-pocket costs can add up over time. Additionally, having dual coverage does not necessarily mean you will be reimbursed twice for the same expense. For example, if you visit the doctor's office twice, you will not be reimbursed twice. Instead, the total amount your two plans will pay for your health expenses will never exceed 100% of the cost of those expenses.

Primary and secondary insurance plans
It is perfectly legal to have two health insurance plans, and many people opt for dual coverage to help with additional costs. However, it is important to understand the difference between primary and secondary insurance and how they work together.
Your primary insurance plan is your main insurance policy that covers your basic medical expenses, such as doctor's visits, lab tests, prescription drugs, and other perks. It will cover your medical care first, up to its coverage limits. With a primary plan, you may owe cost-sharing fees, such as copayments or coinsurance, and you will likely have an annual deductible and an out-of-pocket maximum.
Your secondary insurance plan, on the other hand, is an additional coverage plan that you can buy separately from your primary medical plan. It helps cover the costs of care and services that your primary plan does not. For example, if your primary plan does not cover vision or dental care, you can purchase a secondary plan that does. Secondary insurance typically only comes into effect after your primary insurance reaches its coverage limits. If there are any costs left unpaid by your primary insurer, your secondary coverage will take care of them.
There are several benefits to having a secondary insurance plan. Firstly, it can help lower extra costs by covering some of the expenses that your primary plan does not. Secondly, it can reduce coverage gaps, ensuring that you remain covered even if one of your policies lapses. Finally, it can provide more comprehensive coverage and benefits, especially if your two plans are complementary and cover different aspects of your care.
However, there are also potential downsides to having dual coverage. For instance, you will still be responsible for the monthly premiums and cost-sharing requirements of both plans, which can lead to higher out-of-pocket expenses over time. Additionally, having two insurance plans does not mean you will receive double the coverage. The Coordination of Benefits (COB) provision determines the order in which your health insurance policies pay out, ensuring that you do not exceed 100% of your health costs.

Pros and cons of dual coverage
It is legal to have dual medical insurance coverage, and there are several benefits to this. Firstly, it can provide more comprehensive coverage, offering more benefits and coverage, which can help with medical bills. Secondly, it offers greater protection from loss of coverage. For example, if you have coverage through your parents' or spouse's plan and a company plan, losing your job won't affect your health insurance. Thirdly, dual coverage can reduce coverage gaps. If one policy lapses, you will still have coverage from the second plan.
However, there are also some potential downsides to having dual coverage. One of the main disadvantages is the additional cost. You will be responsible for both plans' monthly premiums and other out-of-pocket expenses, which can add up over time. It is also important to note that having dual coverage does not mean you will receive double the coverage. Your secondary insurance will only kick in after your primary insurance reaches its coverage limits, and you may still have out-of-pocket costs after both plans have paid their share. Additionally, having multiple insurance plans can be confusing, especially when it comes to coordinating the benefits and understanding the order in which your policies will payout.

Scenarios where dual coverage is beneficial
Having dual medical insurance coverage can be beneficial in several scenarios. Firstly, if you frequently incur out-of-pocket medical expenses that your current insurance plan doesn't fully cover, a second plan can help reduce these extra costs. This is especially useful if you anticipate significant healthcare expenses. In this case, dual coverage can lower your overall healthcare costs.
Secondly, dual coverage can provide greater protection against loss of coverage. For example, if you have insurance through your parents' or spouse's plan and also have a company plan, losing your job won't result in a loss of health insurance coverage.
Thirdly, dual coverage can help fill coverage gaps. If one of your policies lapses, the second plan will ensure you still have insurance coverage.
Additionally, dual coverage can offer more comprehensive coverage and benefits, especially if the two plans are complementary and cover different aspects of your care. For instance, one plan might offer better mental health coverage, while the other might have better benefits for another type of care.
Lastly, in certain situations, dual coverage can be beneficial for children. If both parents have family plans that cover their children, the primary insurance is determined by the parent whose birthday comes first in the calendar year. In cases of divorce, children might also have separate insurance policies from each parent.

Coordination of benefits (COB)
It is perfectly legal to have two health insurance plans, and doing so can help cover some of your insurance expenses. However, it is important to understand the difference between primary and secondary insurance and to correctly coordinate your two policies. This is where Coordination of Benefits (COB) comes in.
COB is the process that decides which insurance pays for a claim first. Your primary plan is your main insurance policy that will cover your medical care first. For example, when you see the doctor or need to buy prescription drugs, your primary insurer will cover the bills up to its coverage limits. Your secondary insurance plan typically only kicks in after your primary insurance reaches its coverage limits.
The Benefits Coordination & Recovery Center (BCRC) takes actions to identify the health benefits available to a beneficiary and coordinates the payment process to prevent mistaken payment of Medicare benefits. The BCRC does not process claims, but it does consolidate the activities that support the collection, management, and reporting of information. The Medicare Administrative Contractors (MACs), Intermediaries and Carriers are responsible for processing claims submitted for primary or secondary payment.
In the absence of an agreement, the person with Medicare is required to coordinate secondary or supplemental payment of benefits with any other insurers they may have in addition to Medicare. This ensures that the amount paid by plans in dual coverage situations does not exceed 100% of the total claim, to avoid duplicate payments.
There are several reasons why having multiple insurance plans and using COB may not be a favourable choice. Managing multiple plans and navigating COB can be administratively complex, with extra burdens such as additional paperwork, coordination with multiple providers, and understanding the details of each plan's rules and coverage. It may also not be a cost-effective choice if the combined premiums, deductible copayments, and coinsurance outweigh the benefits received.
