Medicare and Medicaid are two completely separate government programs, and confusing the two is one of the most expensive mistakes a person can make in their healthcare planning.
The Core Medicare and Medicaid Difference
The Medicare and Medicaid difference comes down to two words: eligibility basis.
Medicare is a federal program for people aged 65 and older, as well as certain people under 65 with qualifying disabilities, end-stage renal disease, or ALS. Eligibility is based on age and work history, not income.
You qualify for Medicare because of who you are and how long you have paid into the system.
Medicaid is a joint federal and state program with eligibility determined by income and assets. It serves children, pregnant women, elderly individuals, and people with disabilities who meet specific financial criteria.
Each state runs its own Medicaid program with different rules, income limits, and benefits.
Once you understand that Medicare is about age and disability while Medicaid is about income and need, the confusion between the two begins to resolve quickly.
Medicare Explained: The Four Parts and What They Cost in 2026
Medicare is organized into four parts, each covering a different category of health services.
- Part A covers hospital care, skilled nursing facility stays, hospice, and some home health services. Most people pay no monthly premium for Part A if they or their spouse worked and paid Medicare taxes for at least 10 years. The 2026 Part A deductible is $1,736 per benefit period.
- Part B covers outpatient care, doctor visits, preventive services, and durable medical equipment. The standard 2026 Part B premium is $202.90 per month, though higher earners pay an additional surcharge called the Income-Related Monthly Adjustment Amount. The 2026 Part B annual deductible is $283. After meeting the deductible, Medicare pays 80% of approved costs, leaving you responsible for the remaining 20%
- Part C, also called Medicare Advantage, is an alternative delivery system for Medicare benefits through a private insurer. Part D covers prescription drugs through private plans with their own premiums, deductibles, and formularies.
Understanding what each part of Medicare covers and what it costs is the first step to identifying where the gaps are and what you need to fill them.
Medicaid Explained: State-by-State, Income-Based Benefits
Medicaid provides health benefits to individuals who meet income and asset requirements, and the program looks different depending on where you live.
In Colorado, Medicaid is called Health First Colorado, available at healthfirstcolorado.com. It covers doctor visits, hospital care, prescription drugs, mental health services, and in many cases long-term care in ways that Medicare does not. Cost-sharing for most Medicaid enrollees is minimal or zero.
Medicaid eligibility rules, income thresholds, covered services, and cost-sharing requirements vary significantly from state to state. What qualifies someone for Medicaid in Colorado may not qualify them in another state.
If you think you might qualify for Medicaid, your state’s Medicaid office or a local benefits counselor can walk you through the specific requirements for your state.

How to Tell Which Program You Have
One of the most practical aspects of the medicare and medicaid difference is how you identify which card you carry.
If you have Medicare, you have a red, white, and blue Medicare card issued by the Social Security Administration. It displays your Medicare number, your name, and your Part A and Part B enrollment dates. This card looks the same for every Medicare enrollee regardless of where they live.
If you have Medicaid, you have a state-issued card. In Colorado, the Medicaid card reads “Health First Colorado.” In other states, the card name and appearance vary. Medicaid cards do not look like Medicare cards and are issued by state agencies, not the federal government.
If you are unsure which program you are enrolled in, your local State Health Insurance Assistance Program, or SHIP, office can help you sort it out at no cost.
Can You Have Both Medicare and Medicaid at the Same Time?
Yes, and approximately 12 million Americans are enrolled in both programs simultaneously.
People enrolled in both programs are called dual eligible. For dual eligible individuals, Medicaid may pay Medicare Part B premiums, deductibles, and copays through a group of programs called Medicare Savings Programs. These programs have their own income and asset limits and are separate from Medicaid’s standard benefits.
Dual eligible individuals can also enroll in Dual Eligible Special Needs Plans, or D-SNPs, which are Medicare Advantage plans designed specifically for people who have both Medicare and Medicaid. D-SNPs often include extra benefits such as dental, vision, transportation, and expanded prescription drug formularies.
If you think you might qualify for both programs, checking your eligibility for Medicare Savings Programs could eliminate or significantly reduce your Medicare premiums and cost-sharing.
The Most Expensive Misconception: Medicaid Does Not Fill Medicare Gaps for Most People
The single most costly misconception in Medicare planning is the belief that Medicaid fills the gaps in Medicare for most people.
For the majority of Americans, Medicaid and Medicare do not overlap unless you qualify for both at the same time. Medicaid is income-based. If your income exceeds Medicaid’s eligibility threshold, Medicaid is not available to fill what Medicare does not pay, regardless of how large those costs become.
After meeting the Part B deductible, Medicare pays 80% and you pay 20%. There is no cap on that 20% under Original Medicare. A major surgery, a serious illness, or an extended hospital stay can generate tens of thousands of dollars in cost-sharing.
Discovering this gap after a health event is one of the most financially devastating surprises Medicare enrollees face.
The solution for most Medicare enrollees is a Medicare supplement plan, also called Medigap, which fills those gaps through a private insurance policy and is available regardless of your income.
Common Points of Confusion Between Medicare and Medicaid
Several specific misunderstandings about the difference between medicare and medicaid come up consistently in conversations with new Medicare enrollees.
Medicare Advantage is not Medicaid. Part C is an alternative way to receive Medicare benefits through a private insurer. It is still Medicare. Some Advantage plans include dental, vision, and hearing benefits that overlap with what Medicaid covers for low-income individuals, but Medicare Advantage is available to any Medicare enrollee regardless of income.
A Medicare supplement plan is also not Medicaid. Medigap is a private insurance policy that covers the out-of-pocket costs Original Medicare does not pay, such as deductibles and coinsurance. It is available to any Medicare enrollee regardless of income and is purchased from private insurers through a broker.
Getting these distinctions clear before you make enrollment decisions can save you thousands of dollars and prevent a costly plan mismatch.
