What This Guide Covers About Medicaid and Medicare Premiums

This free informational guide provides an overview of how Medicaid and Medicare premiums work for different groups of people. The guide explains the basic structure of these two government health programs, how they differ, and what costs people might encounter when enrolled in either program.

Medicaid is a joint federal and state program that provides health coverage to millions of Americans with lower incomes. According to the Centers for Medicare & Medicaid Services (CMS), as of 2023, Medicaid covered approximately 72 million people across all states. Medicare, by contrast, is a federal program primarily for people age 65 and older, regardless of income. In 2023, Medicare covered about 66 million beneficiaries.

These two programs operate under different rules, have different premium structures, and serve different populations. Understanding the basic differences helps people learn how each program works and what costs may apply. The guide walks through these distinctions in straightforward language, avoiding technical jargon where possible.

The information in this guide focuses on educational content only. It describes how these programs function and what information is publicly available about their costs. This is not a tool for determining who may participate in either program, and it does not process any applications or transactions with government agencies.

Practical Takeaway: Before reading specific sections, understand that Medicaid and Medicare are separate programs with different rules. Medicaid is income-based and run by both federal and state governments. Medicare is age-based and run by the federal government. Many people are confused about the differences, so taking time to learn about each one separately helps build a foundation for understanding premiums.

Understanding Medicaid Premiums and Costs

Medicaid is designed as a low-cost or no-cost program for people with lower incomes. In most states, Medicaid does not charge monthly premiums at all. According to CMS data, the vast majority of Medicaid beneficiaries pay zero premiums. However, some states operate their Medicaid programs differently and may ask enrollees to pay small monthly fees. These fees, when they exist, are typically between $5 and $50 per month depending on the state and the person's income level.

Beyond premiums, Medicaid programs may include other out-of-pocket costs. These can include copayments (small amounts paid when receiving care), coinsurance (a percentage of the cost shared with the program), and deductibles (amounts paid before coverage begins). However, many states limit these costs for lower-income beneficiaries. For example, a person whose income is below the poverty line in most states will have no or very low copayments.

The rules for Medicaid costs vary by state. Each state designs its own Medicaid program within federal guidelines. This means a person in California may have different costs than someone in Texas, even though both are on Medicaid. Some states cover dental care, vision care, and mental health services at no extra charge. Others may charge small copayments for these services.

Medicaid also operates through different delivery systems in different states. Some people enroll in traditional Medicaid managed by their state health department. Others enroll in managed care plans, which are insurance companies contracted by the state to provide Medicaid services. The copayments and coinsurance rules may differ between traditional Medicaid and managed care plans in the same state.

Practical Takeaway: Most Medicaid enrollees pay no monthly premiums. If costs exist, they are usually very low. To learn what Medicaid costs may apply in a specific situation, contact your state's Medicaid office directly or visit your state's Medicaid website. State rules differ significantly, so general information cannot predict what your costs might be.

How Medicare Premiums Work for Different Parts

Medicare has four parts, and each part covers different services and has different costs. Understanding each part helps clarify where premiums come into play.

Medicare Part A covers hospital services, including inpatient hospital care, skilled nursing facility care, hospice care, and home health services. Most people do not pay a monthly premium for Part A because they or their spouse paid Medicare payroll taxes while working. In 2024, if someone needs to purchase Part A coverage, the premium ranges from $278 to $556 per month depending on work history. However, the vast majority of Medicare beneficiaries pay no Part A premium.

Medicare Part B covers outpatient services such as doctor visits, preventive care, laboratory tests, and durable medical equipment. Part B requires a monthly premium that all beneficiaries must pay. In 2024, the standard Part B premium is $164.90 per month for most people. However, people with higher incomes pay more through an income-related monthly adjustment amount (IRMAA). According to CMS, approximately 7% of Medicare beneficiaries pay higher premiums due to higher incomes.

Medicare Part D covers prescription drugs. Like Part B, Part D requires a monthly premium. The premium amounts vary by plan and insurance company. In 2024, Part D premiums range from roughly $7 to $100 per month depending on the specific plan chosen. The average Part D premium is around $34 per month, though this varies yearly.

Medicare Part C, also called Medicare Advantage, is an alternative to traditional Medicare. Private insurance companies offer Part C plans. Some Part C plans charge no monthly premium beyond the Part B premium, while others charge additional premiums ranging from $0 to several hundred dollars per month. Part C plans typically include drug coverage (Part D), so enrollees do not buy separate Part D coverage.

Income affects Medicare premiums significantly. People with modified adjusted gross income above certain thresholds pay higher Part B and Part D premiums. These thresholds change annually. In 2024, Part B premiums for higher-income beneficiaries range from $230.80 to $560.50 per month, depending on income level. Part D premiums also increase for higher-income individuals.

Practical Takeaway: Medicare has multiple parts with different premium structures. Part A usually has no premium. Part B has a standard premium plus possible income-related increases. Part D has variable premiums by plan. Understanding which parts apply to your situation helps you anticipate costs. Review your income level to determine if you pay standard or higher premiums.

Income Thresholds and How They Affect Your Costs

Income is a critical factor in determining both Medicaid coverage and Medicare costs. Each program uses income in different ways, and understanding these thresholds clarifies what costs might apply.

For Medicaid, income limits vary dramatically by state. Federal law sets a minimum income threshold, but states may set higher limits. In 2024, the federal minimum for parents is about 138% of the federal poverty line, which translates to roughly $2,000 per month for an individual. However, some states have set their limits much higher. For example, some states cover people earning up to 400% of the federal poverty line. These variations mean a person with the same income might qualify in one state but not another.

For Medicare, income affects premiums rather than coverage. Medicare uses Modified Adjusted Gross Income (MAGI) to determine if someone pays higher premiums. MAGI is calculated from your tax return and includes certain types of income even if they are not counted for other purposes. If your MAGI exceeds certain thresholds, you pay surcharges on top of the standard Part B and Part D premiums.

In 2024, the Medicare MAGI thresholds are $97,000 for single individuals and $194,000 for married couples filing jointly. If your MAGI exceeds these thresholds, you pay incrementally higher premiums. For example, a single person with MAGI of $125,000 pays a higher Part B premium than someone with MAGI of $97,000. The surcharge increases in steps as income increases further.

Important note: Medicare premiums use income from two years prior to the current year. This means 2024 premiums are based on 2022 income. This lag can create situations where people with recently decreased income still pay higher premiums until the lower income is reflected in their records.

Both programs allow for certain deductions or exclusions from income. Medicaid rules about what counts as income vary by state and by category (parent, child, elderly, disabled). Medicare's MAGI calculation includes some income sources that people might not
