Neither Medicaid nor private insurance is categorically better. Medicaid costs dramatically less out of pocket, but private insurance gives you access to far more doctors and shorter wait times. The right answer depends on your income, your health needs, and what tradeoffs matter most to you.
Cost: Medicaid Wins by a Wide Margin
The financial gap between Medicaid and private insurance is enormous. A 2021 study published in JAMA Network Open compared low-income adults on Medicaid to similar adults with subsidized Marketplace plans. Total annual healthcare costs were 83% higher for Marketplace enrollees ($4,553 versus $2,484). Out-of-pocket costs were ten times higher: $569 per year on average for Marketplace plans compared to just $45 for Medicaid.
The difference shows up at every point of care. An office visit cost Marketplace enrollees about $20 out of pocket, while Medicaid enrollees paid $2.80. Emergency room visits averaged $106 with private coverage versus $7 with Medicaid. Even prescriptions cost nearly three times more on a Marketplace plan ($6.82 per prescription versus $2.40). These gaps persisted even after federal cost-sharing reductions were applied to the private plans.
Medicaid also has no monthly premiums in most states and rarely charges deductibles. Private insurance, whether through an employer or the Marketplace, almost always involves both. If affordability is your primary concern, Medicaid is hard to beat.
Finding a Doctor: Private Insurance Has a Clear Edge
This is where private insurance pulls ahead, and the gap is significant. About 96% of physicians accept new patients with private insurance. For Medicaid, that number drops to 74%. The difference is driven by lower reimbursement rates: Medicaid pays doctors considerably less than private insurers, so many practices limit how many Medicaid patients they take on or decline them entirely.
Some specialties are particularly hard to access with Medicaid. Only 46% of dermatologists and 46% of psychiatrists accept new Medicaid patients, compared to 98% and 69% for private insurance respectively. Internal medicine acceptance sits at 63% for Medicaid versus 99% for private plans. Primary care and pediatrics fare better, with roughly 76% and 85% of those doctors accepting Medicaid.
A meta-analysis of 34 audit studies, where researchers called doctor’s offices posing as patients, found the real-world impact of these numbers. When callers said they had private insurance, 80% successfully booked an appointment. When they said Medicaid, only 45% did. For specialty care specifically, privately insured callers were 3.3 times more likely to get an appointment than Medicaid callers. Interestingly, the gap has widened since Medicaid expansion: before expansion, Medicaid patients were twice as likely to be turned away, but afterward, they were 3.2 times as likely, probably because more patients entered a system without a proportional increase in participating providers.
What Each One Actually Covers
Medicaid covers several services that standard private health plans often exclude. The most notable is non-emergency medical transportation, which is mandatory in every state’s Medicaid program. If you need a ride to a doctor’s appointment and have no way to get there, Medicaid will arrange it. Private plans almost never cover this.
Medicaid also covers long-term care in nursing homes for people who qualify, which typically requires being unable to independently perform at least two basic activities of daily living (dressing, bathing, eating, using the toilet, moving between a bed and chair, or maintaining continence). Standard private health insurance does not cover custodial nursing home care at all. You’d need a separate long-term care insurance policy for that.
States can also offer optional Medicaid benefits like personal care services, home and community-based services, and care in facilities for people with intellectual disabilities. These are services that fill gaps private insurance largely ignores.
The picture flips for dental and vision care. Private plans often include these as add-ons, and employer plans frequently bundle them in. Medicaid dental coverage for adults varies wildly by state, with no federal minimum requirement. Some states offer comprehensive dental benefits, others cover only emergency extractions, and a few offer nothing. Children on Medicaid are guaranteed dental coverage, but adults have no such guarantee.
Long-Term Care: A Major Medicaid Advantage
For anyone facing the possibility of extended nursing home stays or needing ongoing personal assistance, Medicaid is the primary safety net in the U.S. healthcare system. Private health insurance simply doesn’t cover this kind of care. But Medicaid’s long-term care comes with real limitations.
In many states, nursing home stays are all that Medicaid covers for long-term care. Staying in your own home with in-home aides, using adult day care, or moving into an assisted living facility may not be options under your state’s Medicaid program. A dedicated long-term care insurance policy typically covers all of these settings. Medicaid also rarely guarantees a private room, and you can be moved if a facility stops accepting Medicaid patients or becomes too full. Not all nursing homes accept Medicaid at all.
Patient Satisfaction Is Surprisingly Similar
You might assume people with private insurance are happier with their coverage, but the data doesn’t support that. When researchers analyzed patient satisfaction surveys, Medicaid managed care members rated their health plans at 7.60 out of 10 on average, while commercial (private) managed care members rated theirs at 7.46. The difference wasn’t statistically significant overall. Among people in excellent or very good health, Medicaid members actually rated their plans higher than those with commercial coverage.
This likely reflects the value equation. Medicaid members pay almost nothing out of pocket, so even if finding a doctor takes longer, the financial relief shapes how they experience their coverage. For people in fair or poor health, satisfaction ratings were similar regardless of insurance type.
Who Qualifies for Medicaid
Medicaid eligibility is income-based, and the thresholds vary dramatically depending on where you live. In the 40 states (plus Washington, D.C.) that expanded Medicaid under the Affordable Care Act, most adults qualify if their income falls below 138% of the federal poverty level. For a single person in 2025, that’s roughly $21,600 per year. For a family of three, the poverty level is $26,650, so the 138% threshold lands around $36,800.
In the 10 states that haven’t expanded Medicaid, eligibility for adults without dependent children often sits at 0% of the federal poverty level, meaning non-disabled, childless adults effectively can’t qualify regardless of how little they earn. Georgia is a partial exception, covering adults up to 100% of the poverty level if they meet a work requirement. Wisconsin also covers adults up to 100% of the poverty level through its own approach.
Parents of dependent children generally qualify at higher income levels than childless adults, even in non-expansion states, though the exact thresholds vary by state.
Which Is Better for You
If you’re low-income and qualify for Medicaid, it will cost you a fraction of what any private plan would. Your out-of-pocket spending will be minimal, and you’ll have coverage for services like transportation and potentially long-term care that private plans don’t touch. The tradeoff is real, though: fewer doctors will see you, wait times will be longer, and specialty care can be genuinely difficult to access depending on where you live.
If you have access to employer-sponsored insurance or can afford a Marketplace plan, you’ll pay substantially more but gain a much wider choice of providers and faster access to specialists. For people with complex medical needs requiring frequent specialist visits, that access advantage can make a meaningful difference in the quality and timeliness of care.
For people right at the income boundary who could go either way, the decision often comes down to health status. If you’re generally healthy and mainly need occasional primary care, Medicaid’s cost savings are hard to justify giving up. If you have ongoing conditions requiring coordinated specialist care, the broader provider networks of private insurance may be worth the higher price.
