Medicare Advantage vs. Original Medicare: A Side-by-Side Comparison
Choosing between Medicare Advantage and Original Medicare is one of the most important decisions you will make when you become eligible for Medicare.
Overview: Two Ways to Get Medicare
When you become eligible for Medicare, you have two main paths for receiving your benefits. Original Medicare (also called Traditional Medicare) is the federal government program consisting of Part A (hospital insurance) and Part B (medical insurance). Medicare Advantage (Part C) is offered by private insurance companies approved by Medicare that bundle Part A, Part B, and usually Part D into a single plan.
Both options provide coverage for medically necessary services, but they differ significantly in how you access care, what additional benefits are included, and how much you pay out of pocket.
How Original Medicare Works
Original Medicare is administered directly by the federal government. Part A covers inpatient hospital care, skilled nursing facility care, hospice, and some home health services. Part B covers doctor visits, outpatient care, preventive services, medical equipment, and some home health services.
With Original Medicare, you can see any doctor or go to any hospital that accepts Medicare anywhere in the country without needing referrals. There are no network restrictions. However, Original Medicare does not have an annual out-of-pocket maximum, does not cover prescription drugs, and does not include routine dental, vision, or hearing benefits.
Many people on Original Medicare purchase a Medicare Supplement (Medigap) policy to cover deductibles and coinsurance, plus a separate Part D plan for prescription drugs.
How Medicare Advantage Compares
Medicare Advantage plans are offered by private insurers and must cover everything Original Medicare covers, plus they typically add prescription drugs, dental, vision, hearing, and other benefits. Plans use provider networks (HMO or PPO) and have annual out-of-pocket maximums that protect against catastrophic costs.
The trade-off is that you generally must use in-network providers, may need referrals for specialists, and face prior authorization requirements for some services. Medicare Advantage plans may also have lower reimbursement rates for some providers compared to Original Medicare.
Cost Comparison
With Original Medicare, you pay the Part B premium ($185/month in 2026), Part A deductible ($1,676 per benefit period), Part B deductible ($257/year), plus 20% coinsurance for most outpatient services with no out-of-pocket cap. Adding a Medigap Plan G typically costs $100-$250/month depending on your state and age, plus a Part D plan at $15-$100/month.
With Medicare Advantage, you pay the Part B premium plus a plan premium (often $0), along with copays and coinsurance for services up to an annual out-of-pocket maximum (averaging $4,000-$7,500 depending on the plan). Total costs depend heavily on how much healthcare you use.
Which Option Is Best for You?
Original Medicare with a Medigap supplement is often better for people who want maximum flexibility in choosing providers, travel frequently, have complex health conditions requiring specialist care across different health systems, or can afford the higher monthly premiums for predictable low out-of-pocket costs.
Medicare Advantage is often better for people who want lower monthly premiums, value extra benefits like dental, vision, and hearing in one plan, do not travel extensively, are comfortable using a provider network, and want an annual out-of-pocket maximum for financial protection.
There is no universally right answer. The best choice depends on your individual health needs, financial situation, geographic location, and personal preferences.
Frequently Asked Questions
Can I have both Original Medicare and a Medicare Advantage plan?
No. If you join a Medicare Advantage plan, you must get your Medicare services through that plan. You cannot use Original Medicare for covered services while enrolled in a Medicare Advantage plan (except in rare circumstances).
Is Original Medicare going away?
No. Original Medicare is the foundational federal program and is not being eliminated. Medicare Advantage is an alternative way to receive your Medicare benefits, but Original Medicare remains available to all eligible beneficiaries.
Can I switch between Original Medicare and Medicare Advantage?
Yes. You can switch during the Annual Enrollment Period (October 15 - December 7 each year). You can also disenroll from Medicare Advantage during the MA Open Enrollment Period (January 1 - March 31).
Which costs less — Original Medicare or Medicare Advantage?
It depends on your healthcare usage. Medicare Advantage often has lower premiums but higher per-service costs. Original Medicare with Medigap has higher premiums but more predictable total costs. If you are generally healthy, Medicare Advantage may cost less. If you use a lot of healthcare, the predictability of Medigap may save money.
