Medicare is a federal health insurance program run by the Centers for Medicare & Medicaid Services (CMS). It primarily serves people age 65 and older, regardless of income or medical history. However, some younger people may also be covered, including those with end-stage renal disease, amyotrophic lateral sclerosis (ALS), or who have received Social Security disability benefits for at least 24 months.

Medicare has four main parts, each covering different services. Part A covers hospital stays, skilled nursing facility care, hospice care, and some home health services. Part B covers doctor visits, outpatient care, medical equipment, and preventive services. Part D covers prescription drugs. Part C, also called Medicare Advantage, is an alternative way to receive Parts A and B benefits through private insurance companies that also typically include prescription drug coverage.
According to CMS data, approximately 67 million people were enrolled in Medicare as of 2023. Understanding what each part covers helps you make informed decisions about which coverage options may work for your situation. For example, if you regularly take prescription medications, Part D coverage becomes an important consideration. If you frequently visit specialists, you might want to understand how different plans handle referrals and out-of-pocket costs.
Original Medicare (Parts A and B) uses a fee-for-service model, meaning Medicare pays healthcare providers directly for each service provided. This differs from Medicare Advantage plans, which operate more like traditional health insurance with networks of doctors and hospitals. Beneficiaries in Original Medicare can typically see any doctor or hospital that accepts Medicare, offering greater flexibility in choosing providers.
Cost structures vary significantly. Original Medicare Part A has no monthly premium for most people who paid Medicare taxes while working. Part B has a monthly premium, which in 2024 starts at $164.90 for most beneficiaries, though higher-income individuals pay more. Medicare Advantage plans may have lower or no monthly premiums but often include copayments and coinsurance when receiving care.
Practical takeaway: Write down which Medicare part or parts you currently have or think you might need. Note any medications you take regularly and any doctors you see frequently. This information will help you understand coverage gaps and options that may be available to you.
The Department of Veterans Affairs (VA) operates one of the largest healthcare systems in the United States, providing medical services, disability compensation, and other benefits to veterans and their families. VA benefits are earned through military service and vary based on length of service, discharge status, and service-connected conditions.

VA healthcare includes primary care, surgical services, mental health treatment, rehabilitation services, prescription medications, and preventive care. The VA operates more than 1,200 facilities nationwide, including 170 medical centers and nearly 1,000 outpatient clinics. For fiscal year 2023, the VA served approximately 9.2 million veterans through its healthcare system.
VA disability compensation is a monthly payment for veterans with service-connected disabilities. The VA assigns a disability rating from 0 to 100 percent based on how much a condition impacts a veteran's ability to work and function. A veteran rated 30 percent disabled receives a different monthly payment than one rated 70 percent disabled. These ratings can include physical conditions like arthritis or hearing loss, as well as mental health conditions like post-traumatic stress disorder (PTSD).
Beyond healthcare and disability payments, VA benefits may include education and training programs (like the GI Bill), home loans with favorable terms, life insurance, survivor benefits for families, and vocational rehabilitation for those unable to work due to service-connected disabilities. Some programs assist with job training and placement for veterans transitioning to civilian employment.
Eligibility for VA benefits generally requires an honorable discharge or discharge under honorable conditions. Veterans with other discharge statuses may still be able to receive some benefits depending on their specific circumstances. Active duty service members, members of the National Guard and Reserves with federal active duty service, and certain surviving spouses and dependent children may also be eligible for VA healthcare or other benefits.
Practical takeaway: Locate your discharge papers (DD Form 214) and review your military service dates and discharge status. Make a list of any health conditions you believe are related to your military service. This documentation will be useful when exploring what VA services and benefits may be available to you.
Original Medicare covers many healthcare costs but does not pay for everything. Beneficiaries are responsible for copayments, coinsurance, and deductibles. Understanding these gaps helps explain why many people pursue additional coverage through Medigap (supplemental insurance) or Medicare Advantage plans.

In Original Medicare, Part A has a deductible of $1,632 per benefit period in 2024. After paying this deductible, beneficiaries are fully covered for the first 60 days of a hospital stay. For days 61 through 90, they pay a daily coinsurance amount of $408. For days 91 and beyond, costs increase further. Part B has an annual deductible of $240 in 2024, and beneficiaries typically pay 20 percent coinsurance for most services after meeting this deductible.
Medigap policies are standardized supplemental insurance plans sold by private insurers that work alongside Original Medicare. There are ten different Medigap plans (labeled A through N in most states) that cover different combinations of costs. Plan G, for example, covers the Part B deductible and most coinsurance amounts. Plan N covers similar expenses but may require small copayments for certain office visits and emergency room care. Medigap premiums vary by age, location, and insurance company, ranging from roughly $100 to $300+ monthly depending on the plan.
Medicare Advantage plans operate differently. Instead of supplementing Original Medicare, these plans replace it entirely and are offered by private insurance companies. They typically include prescription drug coverage and may offer additional benefits like dental, vision, or hearing coverage that Original Medicare does not provide. However, Medicare Advantage plans generally require using in-network providers and may have higher out-of-pocket costs if you need specialized care or see out-of-network doctors.
Some beneficiaries qualify for Medicaid, the state-federal health program for people with limited income and resources. When someone qualifies for both Medicare and Medicaid, they are called "dual eligible" and may have reduced out-of-pocket costs through Medicaid assistance programs. Medicaid rules vary significantly by state, so coverage varies geographically.
Practical takeaway: Estimate your typical annual healthcare costs, including doctor visits, medications, and anticipated treatments. Compare this against the monthly premiums, deductibles, and coinsurance of Original Medicare with Medigap versus Medicare Advantage options in your area. Understanding your personal healthcare needs makes it easier to compare plans that might work for you.
Veterans who qualify for both Medicare and VA healthcare have a decision to make about how to use each system. Some veterans prioritize VA healthcare because they may pay nothing out-of-pocket if they are rated disabled or meet certain other criteria. Others use Medicare as their primary coverage and VA services as supplemental care. Both approaches have trade-offs worth understanding.

When a veteran uses VA healthcare as primary coverage, they receive treatment through the VA system exclusively for most services. The VA coordinates their care, manages their medical records within the VA system, and prescriptions are filled through VA pharmacies. This approach works well for veterans who live near VA facilities and prefer consolidating their care in one system. However, VA wait times for certain services may be longer in some areas, and access to specialists depends on VA availability.
When a veteran uses Medicare as primary coverage and VA as supplemental, they might see their primary care doctor through Medicare and visit the VA for specific services like mental health treatment, specialized rehabilitation, or preventive screenings the VA excels at providing. Some veterans use both systems for different types of care based on convenience and quality considerations.
Age affects this decision significantly. Veterans under 65 cannot use Medicare and must rely on VA healthcare or purchase private insurance. At age 65, Medicare becomes available, and the veteran must decide how to integrate it with their VA coverage. Veterans age 65 and older in the VA system sometimes reduce their VA usage if they enroll in Medicare because Medicare becomes their primary coverage for many services.
