Medicare is a federal health insurance program designed for people age 65 and older, as well as some younger people with disabilities and those with end-stage renal disease. According to the Centers for Medicare and Medicaid Services (CMS), about 67 million people were enrolled in Medicare as of 2023. The program consists of four main parts, each covering different services and costs.

Part A covers hospital insurance, including inpatient hospital care, skilled nursing facility care, hospice care, and some home health services. Most people do not pay a monthly premium for Part A if they or their spouse paid Medicare taxes for at least 10 years while working. Part B covers medical insurance, including doctor visits, outpatient services, medical equipment, and preventive care. Part B requires a monthly premium, which in 2024 is $174.70 for most beneficiaries, though higher earners pay more.
Part D provides prescription drug coverage through private insurance companies approved by Medicare. Monthly premiums vary by plan and region, ranging from roughly $5 to $100 monthly depending on the medications covered and the plan selected. Part D includes a coverage gap period, sometimes called the "donut hole," where beneficiaries pay a larger share of costs before catastrophic coverage begins.
Medigap, or Medicare Supplement Insurance, is private insurance sold by companies to help cover costs that Original Medicare does not pay, such as copayments, coinsurance, and deductibles. There are 10 standardized Medigap plans labeled A through N, each offering different levels of coverage. A person with Original Medicare can purchase one Medigap policy.
Alternatively, Medicare Advantage (Part C) is an all-in-one alternative to Original Medicare, offered by private insurance companies. These plans include hospital and medical coverage, and most include prescription drug coverage. Medicare Advantage plans often have lower monthly premiums than Original Medicare plus Medigap, but typically feature networks of doctors and hospitals and may have prior authorization requirements.
Practical Takeaway: Understanding the four parts of Medicare and the difference between Original Medicare with Medigap versus Medicare Advantage helps clarify which coverage structure may better match your medical needs and financial situation. Review the Summary of Benefits document for any plan you consider to understand specific coverage details.
Medicaid is a joint federal and state program that provides health coverage to millions of low-income individuals, including seniors age 65 and older. Unlike Medicare, which is uniform nationwide, Medicaid rules vary significantly by state. According to the Kaiser Family Foundation, approximately 9.6 million seniors were enrolled in Medicaid or dual coverage (both Medicare and Medicaid) in 2022.

For seniors, Medicaid covers many services that Medicare does not, including long-term care in nursing homes and assisted living facilities, adult day care, and personal care services. Income and asset limits differ by state, but generally, seniors must have limited income and resources to meet Medicaid requirements. As of 2024, most states set the income limit at or below 100 to 138 percent of the federal poverty level, which translates to roughly $1,550 to $2,150 monthly for an individual.
Some states offer Medicaid programs specifically designed for seniors and people with disabilities, such as Home and Community-Based Services (HCBS) waivers. These allow people to receive long-term services at home or in community settings rather than institutional facilities. For example, Michigan's Medicaid waiver program serves approximately 40,000 seniors in home-based settings annually.
Dual-eligible seniors—those covered by both Medicare and Medicaid—represent a growing population. According to CMS data, over 12 million people were dual-eligible as of 2023. These individuals often face complex coverage rules, as Medicare is the primary payer for most services, with Medicaid providing supplemental coverage and services Medicare does not cover.
Special enrollment periods and transitions occur when seniors turn 65 or experience changes in income or household composition. Some states have transitioned seniors from traditional Medicaid to managed long-term care plans, which coordinate services through insurance companies while maintaining coverage. Examples include New York's Program of All-Inclusive Care for the Elderly (PACE) and similar programs in other states.
Practical Takeaway: Research your specific state's Medicaid program rules regarding income limits, covered services, and application procedures. If you are nearing 65 and currently on Medicaid, contact your state Medicaid office to understand how your coverage will change when you become Medicare-eligible.
Long-term care insurance is a private insurance product that covers costs associated with extended care services, such as nursing home care, assisted living, home health aides, or adult day care. According to the American Association for Long-Term Care Insurance, the average monthly cost of nursing home care in the United States is approximately $8,821, while assisted living averages $4,500 monthly. These costs can deplete savings quickly without insurance or other funding sources.

Traditional long-term care insurance policies require underwriting based on health status. Premiums vary widely depending on age at purchase, health history, coverage amounts, and elimination periods (the waiting period before benefits begin). A 55-year-old purchasing a policy with $200 daily coverage may pay $1,000 to $2,500 annually, while someone purchasing at age 75 could pay three to four times that amount. Premiums may increase over time, sometimes by 15 to 40 percent.
Hybrid long-term care products combine life insurance or annuities with long-term care riders, allowing policyholders to access death benefits or annuity funds to pay for care. These products appeal to people concerned about "losing" premiums if they never need long-term care. However, they typically cost more upfront and offer lower daily care benefits than traditional long-term care insurance.
Some employers offer group long-term care insurance, which typically costs less than individual policies because risk is spread across a larger pool. The Family Caregiver Alliance estimates that 42 million family caregivers provide unpaid care to adult family members annually, often resulting in lost work time and reduced retirement savings. Group long-term care insurance through employers represents one way to address this gap.
For those without private insurance, self-funding through savings, annuities, or reverse mortgages may cover some long-term care costs. Medicaid serves as a safety net for those whose resources are depleted, though it generally only covers nursing home care and specific home and community services, and may limit choice of providers.
Practical Takeaway: Consider purchasing long-term care insurance when you are younger and healthier to avoid high premiums or denial due to pre-existing conditions. If insurance is not an option, explore Medicaid planning strategies with an elder law attorney and consider how family, savings, and community resources might combine to address future care needs.
Beyond Original Medicare, Medigap, and Medicare Advantage, several supplemental insurance products help seniors manage out-of-pocket healthcare expenses. Dental insurance for seniors is not typically covered by Medicare, yet the American Dental Association reports that about 67 percent of adults age 65 and older have dental insurance through private plans or employer retiree coverage. Standalone dental plans for seniors generally cost $10 to $50 monthly and cover preventive services at higher rates than major procedures.

Vision insurance similarly covers eye exams, glasses, and contact lenses that Original Medicare does not. According to the Vision Service Plan, the average cost of vision insurance for seniors ranges from $5 to $20 monthly. However, many seniors find that paying out-of-pocket for routine eye exams ($100-$200 every one to two years) and glasses ($150-$400) may be comparable to or less expensive than paying annual premiums plus copayments.
Hospital indemnity insurance provides daily cash benefits when a person is hospitalized, regardless of other insurance coverage. These plans pay a fixed amount per day of hospitalization—typically $100 to $500—and can help with out-of-pocket costs, deductibles, or lost income. Premiums range from $20 to $100 monthly, depending on age and benefit levels.
Critical illness insurance pays a lump sum benefit (typically $
