If you are turning 65 or reviewing your Medicare options this year, you have a big choice ahead: stick with Original Medicare (Parts A and B) or enroll in a Medicare Advantage plan (Part C). Both paths give you Medicare coverage, but how you receive that coverage, what it costs, and which doctors you can see are all different.
Not sure which direction is right for you? Talk to an independent Medicare broker who can compare plans side by side at no cost to you. Call The Big 65 at 877-850-0211.
This guide breaks down each option using the latest 2026 numbers from the Centers for Medicare and Medicaid Services (CMS) so you can make a confident decision.
What Is Original Medicare?
Original Medicare is the federal health insurance program run directly by the U.S. government. It has two parts:
- Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services.
- Part B (Medical Insurance) covers doctor visits, outpatient procedures, preventive screenings, lab work, durable medical equipment, and mental health services.
When you use a medical service, Medicare pays its share and you pay the rest through deductibles, copays, and coinsurance. There is no annual cap on what you could owe out of pocket, which is why many people pair Original Medicare with a Medicare Supplement (Medigap) plan to limit their exposure.
Original Medicare does not include prescription drug coverage. You need to add a standalone Part D plan if you want help with medication costs.
What Is Medicare Advantage?
Medicare Advantage (also called Part C) is an alternative way to receive your Medicare benefits. Private insurance companies approved by Medicare offer these plans. When you enroll in a Medicare Advantage plan, you still have Medicare, but a private insurer manages your Part A and Part B coverage instead of the federal government handling it directly.
Most Medicare Advantage plans bundle Part A, Part B, and Part D (prescription drugs) into a single plan. Many also include extra benefits like dental, vision, and hearing coverage, gym memberships, and wellness programs that Original Medicare does not offer.
The trade-off? Medicare Advantage plans typically use provider networks (HMOs, PPOs, or other structures), which means you may need to choose doctors and hospitals within the plan’s network or pay more to go out of network.
Original Medicare vs. Medicare Advantage: Side-by-Side Comparison
| Feature | Original Medicare (Parts A and B) | Medicare Advantage (Part C) |
|---|---|---|
| Run by | Federal government | Private insurance companies approved by Medicare |
| Doctor and hospital choice | Any provider in the U.S. that accepts Medicare | Usually limited to a plan network (HMO, PPO) |
| Referrals needed for specialists | No | Often yes (HMO plans); usually no (PPO plans) |
| Prescription drug coverage | Not included; add a standalone Part D plan | Usually included (most plans bundle Part D) |
| Extra benefits (dental, vision, hearing) | Not included | Often included at no extra premium |
| Out-of-pocket maximum | No annual cap | Required; varies by plan (2026 CMS cap: $9,350 in-network for most plans) |
| Medigap eligibility | Can purchase a Supplement plan | Cannot hold a Medigap policy at the same time |
| Monthly premium | Part B: $202.90/month (2026 standard); Part A: $0 for most | Part B premium plus plan premium (many plans charge $0 extra) |
Bottom line: Original Medicare gives you maximum freedom to pick any Medicare-accepting provider in the country. Medicare Advantage bundles more services together and caps your yearly spending, but limits your provider choices.
How Do Costs Compare in 2026?
Understanding the dollars-and-cents differences helps you figure out which path fits your budget. Here are the key 2026 numbers confirmed by CMS:
Original Medicare Costs (2026)
- Part A premium: $0 for most people (you qualify if yor or your spouse paid Medicare taxes for at least 10 years)
- Part A hospital deductible: $1,762 per benefit period (up from $1,676 in 2025)
- Part B premium: $202.90 per month (up from $185.00 in 2025)
- Part B deductible: $283 per year (up from $257 in 2025)
- Part B coinsurance: 20% of Medicare-approved amounts after the deductible
- Out-of-pocket maximum: None. Your costs are uncapped unless you carry a Medigap policy.
A beneficiary paying the standard Part B rate faces an annual cost floor of about $2,718 in premiums and deductibles alone, before any coinsurance kicks in. That is roughly $241 more than in 2025.
Medicare Advantage Costs (2026)
- Part B premium: You still pay $202.90/month (this does not go away)
- Plan premium: Varies; many plans charge $0 additional premium
- Deductibles: Vary by plan; some charge $0
- Copays and coinsurance: Vary by plan and service type
- Out-of-pocket maximum: Required on all plans. The CMS-set ceiling for in-network services is $9,350 for most plans in 2026, though many plans set their limit lower.
- Part D drug cap: $2,100 annual out-of-pocket maximum for covered prescriptions in 2026
The built-in spending cap is one of the biggest financial differences. If you have a major health event on Original Medicare without a Supplement plan, your 20% coinsurance on a $100,000 hospital bill could cost you $20,000 or more. On Medicare Advantage, your costs would stop at the plan’s out-of-pocket maximum.

How Do Provider Networks Differ?
This is often the deciding factor for people choosing between Original Medicare and Medicare Advantage.
Original Medicare: Go Anywhere
With Original Medicare, you can visit any doctor, specialist, or hospital in the United States that accepts Medicare. According to CMS data, roughly 97% of non-pediatric physicians participate in Medicare. You do not need referrals to see specialists, and you can get care in any state without worrying about network boundaries.
This flexibility matters most if you:
- Travel frequently or split time between two states
- See specialists at major medical centers far from home
- Want the freedom to switch doctors without checking network lists
Medicare Advantage: Network-Based Care
Medicare Advantage plans use networks. The two most common types are:
- HMO (Health Maintenance Organization): You must use in-network doctors and hospitals except in emergencies. You typically need a referral from your primary care physician to see a specialist.
- PPO (Preferred Provider Organization): You can see out-of-network providers, but you will pay more. Specialist referrals are usually not required.
Before enrolling in any Medicare Advantage plan, verify that your current doctors, preferred hospital, and pharmacy are all in the plan’s network. Networks can change from year to year, so checking annually during the open enrollment period is a good habit.
What Extra Benefits Does Medicare Advantage Offer?
One reason Medicare Advantage has grown in popularity is the extra benefits that Original Medicare simply does not cover. Common extras include:
- Dental care: Routine cleanings, X-rays, and sometimes major work like crowns or dentures
- Vision care: Annual eye exams, frames, and lenses
- Hearing care: Hearing tests and hearing aid discounts or coverage
- Fitness programs: Gym memberships through programs like SilverSneakers or similar
- Telehealth: Virtual doctor visits, often at $0 copay
- Over-the-counter allowances: Quarterly allowances for health-related items
- Transportation: Rides to medical appointments
These extras are not standardized. Each plan picks which benefits to include and at what level. A $0-premium plan in one county might offer generous dental coverage while another $0-premium plan in the same county offers very little. Comparing plan details during the Annual Election Period (October 15 through December 7) is essential.
What About Prescription Drug Coverage?
Original Medicare does not cover prescription drugs. If you want drug coverage, you need to enroll in a standalone Medicare Part D plan. Part D plans are sold by private insurers, and each plan has its own formulary (list of covered drugs), premium, deductible, and pharmacy network.
Medicare Advantage plans usually bundle Part D drug coverage into the plan. For 2026, the annual out-of-pocket maximum for Part D covered prescriptions is $2,100, regardless of whether you get drug coverage through a standalone Part D plan or through a Medicare Advantage plan that includes Part D.
If you take expensive specialty medications, compare the formularies carefully. A drug that costs $10 a month on one plan could cost $100 on another.
Can You Switch Between Original Medicare and Medicare Advantage?
Yes, but timing matters. Here are the enrollment periods that let you make changes:
- Annual Election Period (AEP): October 15 through December 7 each year. You can switch from Original Medicare to Medicare Advantage, switch between Advantage plans, or drop Advantage and go back to Original Medicare. Changes take effect January 1.
- Medicare Advantage Open Enrollment Period (OEP): January 1 through March 31. If you are already in a Medicare Advantage plan, you can switch to a different Advantage plan or drop Advantage and return to Original Medicare. Changes take effect the first of the following month.
- Special Enrollment Periods (SEPs): Triggered by qualifying life events such as moving to a new area, losing employer coverage, or qualifying for Medicaid.
One important caution: if you leave Original Medicare plus a Medigap policy for Medicare Advantage, you may not be able to get that same Medigap policy back at the same rate if you later decide to switch back. Medigap insurers can use medical underwriting (in most states) when you apply outside of your initial open enrollment period. This is a decision worth discussing with a qualified Medicare broker before making any move.

Which Option Is Better for You?
There is no universal “better” choice. The right answer depends on your health needs, budget, and preferences. Here is a quick guide:
Original Medicare may be the better fit if you:
- Want unrestricted access to any Medicare-accepting doctor or hospital nationwide
- Travel often or live part of the year in another state
- Are willing to pay a Medigap premium for predictable, low out-of-pocket costs
- Prefer to build your own coverage by selecting separate Part D and Supplement plans
- See specialists regularly and do not want referral requirements
Medicare Advantage may be the better fit if you:
- Want an all-in-one plan that bundles hospital, medical, drug, and extra benefits
- Prefer lower monthly premiums (many plans charge $0 beyond the Part B premium)
- Are comfortable using a network of local doctors and hospitals
- Value extra benefits like dental, vision, hearing, and fitness programs
- Want the financial protection of a yearly out-of-pocket cap
Your health situation can also tip the balance. If you manage multiple chronic conditions and see several specialists, Original Medicare’s open-access model may save you headaches. If you are generally healthy and want to keep costs low with added perks, Medicare Advantage could be a smart choice.
Frequently Asked Questions
Can I have both Original Medicare and Medicare Advantage at the same time?
No. You must choose one or the other. If you enroll in a Medicare Advantage plan, your Part A and Part B benefits are delivered through that plan. You cannot use Original Medicare to pay for services at the same time. You also cannot hold a Medigap policy while enrolled in Medicare Advantage.
Is Medicare Advantage really free?
Not exactly. Many Medicare Advantage plans advertise $0 monthly premiums, but you still pay your Part B premium ($202.90 per month in 2026). You also pay copays, coinsurance, and deductibles when you use services. The $0 refers only to the additional plan premium on top of Part B.
What happens if my doctor leaves my Medicare Advantage network?
If your doctor drops out of your plan’s network, you have a few options. You can switch to a different Medicare Advantage plan that includes your doctor during the Annual Election Period. You can also use the Medicare Advantage Open Enrollment Period (January 1 through March 31) to switch plans or return to Original Medicare.
Does Original Medicare cover dental, vision, or hearing?
Original Medicare provides very limited coverage for these services. It covers medically necessary dental work done in a hospital setting, diagnostic eye exams for conditions like glaucoma, and cochlear implants. Routine dental cleanings, eye exams for glasses, and hearing aids are not covered. You would need a separate dental, vision, or hearing plan, or a Medicare Advantage plan that includes these benefits.
When should I decide between Original Medicare and Medicare Advantage?
Your first chance is your Initial Enrollment Period, which starts three months before the month you turn 65 and ends three months after. After that, you can make changes during the Annual Election Period (October 15 through December 7) each year.
