Yes, you can have both Medicaid and private insurance, and many people do
Medicaid and private insurance can work together. When you have both, Medicaid typically pays second — after your private insurance has paid its share. This arrangement is called dual coverage, and it can lower your out-of-pocket costs because the two plans coordinate to cover more of your medical bills.
The key is that your private insurance is the primary payer. Your doctor's office or hospital bills your private insurance first. Once that plan pays what it owes, the claim goes to Medicaid, which may cover some or all of what your private insurance didn't pay. You are not required to tell your private insurer that you have Medicaid, but you must tell Medicaid about your private insurance when you report your income and household information.
Key Takeaways
- Private insurance pays first, then Medicaid pays second on the same medical bill, which can reduce what you owe out of pocket.
- You must report your private insurance to Medicaid when you apply or renew, because it affects your income limits and what Medicaid will pay.
- Some people get private insurance through an employer and Medicaid at the same time because their income is low enough to meet Medicaid rules.
- Medicaid will not pay premiums, deductibles, or copays for your private insurance, but it may cover costs your private plan does not.
When dual coverage happens most often
The most common situation is having employer-sponsored insurance and Medicaid at the same time. This occurs when your job offers health insurance but your household income is still low enough to meet your state's Medicaid income limit. You keep the employer plan as primary coverage and use Medicaid to fill gaps — covering deductibles, copays, or services your employer plan excludes.
Another scenario is when you have a spouse or parent with employer insurance that covers you, but your own income qualifies you for Medicaid. The family member's plan is primary; Medicaid is secondary. A third situation involves people who buy private insurance on the health insurance marketplace and also meet Medicaid income thresholds in their state. This is less common because most states that expanded Medicaid have income limits that exclude marketplace shoppers, but it can happen in non-expansion states or during specific life changes.
How Medicaid coordinates with your private plan
When you have both plans, the billing process works in a specific order. Your provider submits the claim to your private insurance first. The private insurer processes it, applies your deductible if you have not met it, and pays its share. The provider then submits the remaining balance to Medicaid with a copy of what the private insurance paid.
Medicaid reviews the claim and decides whether to pay the rest. Medicaid will not pay your private insurance premiums, deductibles, or copayments — those are your responsibility. However, Medicaid may cover services that your private insurance denied or excluded, such as dental work, vision care, or mental health services that fall outside your private plan's limits. The result is that you typically owe less than you would with either plan alone.
Reporting your private insurance to Medicaid
When you apply for Medicaid or renew your coverage, you must report any private insurance you have. This includes employer plans, marketplace plans, or coverage through a family member. Medicaid uses this information to determine whether you still meet income and resource limits, because having access to employer insurance can affect your may be able to access in some states.
You will need to provide the name of your private insurance company, your policy number, and the name of the person whose job the insurance is through (if it is employer-sponsored). If your private insurance ends, you must report that change to Medicaid within 30 days in most states. Failing to report changes can result in Medicaid coverage being cancelled or Medicaid trying to recover payments it made when you were no longer may be able to access.
What Medicaid will not pay for when you have private insurance
Medicaid will not cover your private insurance premiums, no matter how high they are. If your employer requires you to pay part of the premium, that cost is yours alone. Medicaid also will not pay your deductible, copayment, or coinsurance — the amounts your private plan says you owe. Those are your responsibility as the policyholder.
Some states have programs that help low-income people pay private insurance premiums, but these are separate from Medicaid and have their own income limits and rules. Your state Medicaid office or a local community action agency can tell you whether such a program exists where you live. If you cannot afford your private insurance premium and Medicaid will not cover it, you may be able to drop the private plan and rely on Medicaid alone, depending on your state's rules.
How having both plans affects your Medicaid may be able to access
In most states, having private insurance does not disqualify you from Medicaid if your income is low enough. However, some states count the value of employer-sponsored insurance as income when deciding whether you meet the Medicaid income limit. This is rare and varies by state, so you should ask your state Medicaid office directly whether your private insurance affects your may be able to access.
If you are on Medicaid and your employer offers insurance, you are generally not required to take it — Medicaid will not penalize you for turning down employer coverage. However, if you do take the employer plan, you must report it to Medicaid. Some people choose employer insurance over Medicaid because the employer plan offers better coverage or lower out-of-pocket costs, even though they still meet Medicaid income limits.
Losing one plan while keeping the other
If your private insurance ends — because you lose your job, your employer stops offering it, or you drop it — you keep your Medicaid coverage as long as you still meet income and other requirements. You must report the loss of private insurance to Medicaid within 30 days. Medicaid then becomes your primary and only coverage until you gain new private insurance.
If you lose Medicaid but keep your private insurance, your private plan becomes your only coverage. This might happen if your income rises above your state's Medicaid limit or if you no longer meet other may be able to access rules. You will receive a notice from Medicaid before your coverage ends, usually giving you at least 10 days' notice. After that date, you will need to rely entirely on your private insurance for medical bills.
Frequently Asked Questions
Do I have to tell my private insurance company that I have Medicaid?
No. Your private insurer does not need to know about your Medicaid coverage. However, you must tell Medicaid about your private insurance. Medicaid needs this information to coordinate benefits and determine your may be able to access.
Will Medicaid pay my private insurance copay or deductible?
No. Medicaid will not pay premiums, copays, deductibles, or coinsurance for your private plan. Those costs are your responsibility. Medicaid may cover services your private plan does not cover, but it will not pay what your private plan says you owe.
What happens if my private insurance and Medicaid cover different amounts for the same service?
Your private insurance pays first up to what it owes. Medicaid then reviews the claim and pays based on what Medicaid allows for that service. If Medicaid's allowed amount is lower than what your private plan paid, you do not get a refund — the private plan's payment stands.
Can I drop my private insurance and keep Medicaid?
Yes, in most cases. If you have employer insurance and want to drop it, you can do so without losing Medicaid, as long as you still meet Medicaid income and other requirements. You must report the change to Medicaid within 30 days.
Does having private insurance make me ineligible for Medicaid?
Not in most states. Having access to private insurance does not automatically disqualify you from Medicaid if your income is low enough. A few states may count employer insurance value as income, but this is uncommon. Contact your state Medicaid office to confirm how your private insurance affects your may be able to access.
