Medicare is a federal health insurance program for people age 65 and older, regardless of income or health status. According to the Centers for Medicare & Medicaid Services, as of 2024, approximately 68 million people receive Medicare benefits. The program has several distinct parts, each covering different types of care, and understanding how these parts work together can help seniors make informed decisions about their healthcare costs.

Medicare Part A covers hospital insurance, including inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. Most people who worked and paid Medicare taxes do not pay a monthly premium for Part A. However, Part A does include costs like deductibles and coinsurance that beneficiaries must pay out-of-pocket. For example, in 2024, the Part A hospital deductible is $1,632 per benefit period.
Medicare Part B covers outpatient medical services, including doctor visits, preventive care, mental health services, and durable medical equipment. Part B requires a monthly premium, which in 2024 averages $164.90 for most beneficiaries, though this amount increases for higher-income individuals. Part B also involves a deductible (currently $240 per year) and coinsurance costs, where beneficiaries typically pay 20 percent of approved charges after the deductible is met.
Medicare Part D addresses prescription drug coverage through private insurance plans approved by Medicare. These plans vary by region and by the specific drugs covered. Part D includes a coverage gap sometimes called the "donut hole," where beneficiaries pay more out-of-pocket for medications after reaching an initial spending threshold. The Inflation Reduction Act of 2022 changed Part D cost-sharing, capping out-of-pocket prescription drug costs at $2,000 per year beginning in 2025.
Medicare Part C, also known as Medicare Advantage, is an alternative way to receive Medicare benefits through private insurance companies. These plans must cover all Part A and Part B services and typically include prescription drug coverage (Part D). Many Medicare Advantage plans charge lower or no premiums and have lower out-of-pocket costs than Original Medicare, though they often restrict which doctors and hospitals beneficiaries can use.
Practical Takeaway: Review each Medicare part to understand what types of care each covers and what out-of-pocket costs apply. Create a document listing your current providers and medications, then cross-reference this information with coverage summaries from different plan options during the Medicare Annual Enrollment Period (October 15 through December 7 each year).
Medigap policies are supplemental insurance plans sold by private insurance companies that help pay for costs that Original Medicare does not cover, such as copayments, coinsurance, and deductibles. These policies work alongside Original Medicare (Part A and Part B) to reduce out-of-pocket expenses. According to data from the National Association of Insurance Commissioners, approximately 9 million Medicare beneficiaries have some form of Medigap coverage.

Medigap plans are standardized by the federal government, meaning that a Plan G offered by one insurance company provides the same benefits as a Plan G from another company. The plans are named with letters (A, B, D, G, K, L, M, and N), and each letter represents a different combination of covered services. For example, Plan G covers the Part A hospital deductible, Part B coinsurance and copayments, skilled nursing facility coinsurance, and foreign travel emergency medical care. Plan N covers similar benefits but typically charges a copayment for doctor visits and emergency room visits.
The cost of Medigap premiums varies based on several factors: the insurance company offering the plan, your age, your location, and the pricing method the company uses. Three common pricing methods exist. Community rating means all people pay the same premium regardless of age. Issue-age rating means the premium is based on your age when you first buy the policy. Attained-age rating means the premium increases as you get older. Understanding which pricing method an insurance company uses can help you estimate how your premiums might change over time.
Enrollment timing for Medigap is important because insurance companies can deny coverage or charge more based on pre-existing conditions if you do not enroll during your initial open enrollment period. This period lasts six months, beginning the month you turn 65 and are enrolled in Medicare Part B. During this six-month window, insurance companies cannot deny you coverage or charge more based on health status for any Medigap plan they offer.
Medigap policies do not cover long-term care, dental care, vision care, or hearing aids, so seniors may need additional coverage or payment plans for these services. Some beneficiaries choose to explore Medicare Advantage plans instead of using Original Medicare with Medigap, as these alternatives may offer more comprehensive coverage in certain areas, though typically with more restrictions on provider choice.
Practical Takeaway: Obtain premium quotes from multiple insurance companies for the same Medigap plan letter in your area. Compare not only the current premium but also the pricing method used, as this affects long-term costs. Review your coverage during the Medicare Annual Enrollment Period each year to ensure your plan still meets your healthcare needs.
Seniors with limited income and resources may find support through several government programs designed to reduce healthcare costs. The Medicaid program, which varies by state, provides health coverage to eligible low-income individuals and families. Many states offer pathways for seniors age 65 and older to receive both Medicare and Medicaid, a situation called "dual eligibility." According to the Kaiser Family Foundation, approximately 12 million Medicare beneficiaries are also enrolled in Medicaid.

The Medicare Savings Program (MSP) helps low-income seniors by paying some or all of their Medicare premiums, deductibles, and coinsurance. This program includes four subprograms: the Qualified Medicare Beneficiary (QMB) program, the Specified Low-Income Medicare Beneficiary (SLMB) program, the Qualified Individual (QI) program, and the Qualified Disabled and Working Individual (QDWI) program. Each program has different income limits and covers different costs. For example, the QMB program covers Part A and Part B premiums, Part A hospital deductible, Part B deductible, coinsurance, and copayments for those with income up to 100 percent of the federal poverty level.
The Extra Help program, formally known as the Low-Income Subsidy (LIS) program, assists seniors with limited income in paying Medicare Part D prescription drug plan premiums, annual deductibles, and coinsurance. A single person with annual income up to $21,550 (or $43,050 for a married couple) in 2024 may potentially benefit from this program. The program reduces out-of-pocket drug costs significantly, and in many cases, beneficiaries pay no premium for their prescription drug plan or very small copayments.
State Pharmaceutical Assistance Programs (SPAPs) provide prescription drug cost relief through state government programs. Each state operates its own program with different income thresholds and covered drugs. Some states restrict enrollment to seniors age 65 and older, while others include younger disabled individuals. These programs may cover medications not included in Medicare Part D or may provide additional assistance beyond what Medicare offers.
Other programs include Prescription Assistance Programs (PAPs) offered directly by pharmaceutical manufacturers, which provide free or reduced-cost medications to individuals who cannot pay for prescriptions. Additionally, some nonprofits and charitable organizations provide financial assistance for medical expenses, prescription drugs, and healthcare services to seniors who meet certain criteria.
Practical Takeaway: Contact your state Medicaid office or visit the official Medicare website to learn which low-income assistance programs may be available in your area based on your income and family size. Gather documentation of your income from the past 30 days (pay stubs, Social Security statements, or bank statements) before contacting these programs, as income verification is typically required.
Health Savings Accounts (HSAs) and Flexible Spending Arrangements (FSAs) are employer-sponsored or individual accounts that allow people to set aside pre-tax money for qualified medical expenses. These accounts can provide significant savings when managed strategically, particularly for seniors with predictable healthcare costs or substantial anticipated medical expenses.
