We’ve been writing about Medicare for three years now, and Medicare Advantage is probably the topic that generates the most questions from our readers. That makes sense — over half of all Medicare beneficiaries have chosen Advantage plans, but most people we talk to still aren’t sure whether they should.
Our team spent about a month pulling apart Medicare Advantage plans from every major insurer before putting this guide together. David Chen, who leads our Medicare coverage, personally called into UnitedHealthcare, Humana, and Aetna as a prospective member to see how their sales processes actually work. (Short version: some were great, some were not.)
Look, Medicare is confusing. Parts A, B, C, D — it sounds like someone designed it to be hard to understand, and honestly, it kind of was. We can’t make it simple, but we can make it clearer. This guide breaks down what Advantage plans actually cover, what they cost, when you can sign up, and how to figure out if one is right for you.
One thing worth knowing upfront: the Inflation Reduction Act changed the math on prescription drugs pretty significantly. The new $2,000 annual cap on Part D out-of-pocket costs and the $35 insulin cap are a real deal for a lot of people, and most Advantage plans include Part D coverage.
Keep in mind that Medicare rules change every year — CMS updates premiums, deductibles, and out-of-pocket limits annually. We do our best to keep this current, but always double-check the latest numbers at medicare.gov or call your state SHIP program (it’s free, and they’re genuinely helpful). Want to talk it through?

Medicare Advantage: A Complete Guide for 2026
Quick answer: Medicare Advantage (Part C) is an alternative to Original Medicare offered through private insurers. Most plans cost $0/month (you still pay Part B), include drug coverage, and add dental, vision, and hearing benefits. The trade-off: you typically must use in-network doctors.
Medicare Advantage — also known as Medicare Part C — gives beneficiaries an alternative way to receive their Medicare coverage. Instead of receiving benefits directly through the federal government, you enroll in a private plan approved by the Centers for Medicare & Medicaid Services (CMS). Over 50% of Medicare beneficiaries now choose Medicare Advantage plans, with UnitedHealthcare and Humana as the two largest insurers.
Understanding the differences between Medicare Advantage and Original Medicare is one of the most important healthcare decisions you’ll make.
What Medicare Advantage Covers
Every Medicare Advantage plan must cover all the same services as Original Medicare Parts A and B. That means:
- Hospital care (inpatient stays, skilled nursing, hospice)
- Medical care (doctor visits, outpatient services, preventive care)
- Emergency and urgent care
Most plans go further by bundling additional benefits:
- Prescription drug coverage (Part D) — included in most plans
- Dental care — cleanings, X-rays, and often basic restorative work
- Vision care — eye exams and allowances for glasses or contacts
- Hearing coverage — hearing exams and hearing aid allowances
- Fitness memberships — programs like SilverSneakers
- Transportation — rides to medical appointments
- Over-the-counter allowances — quarterly credits for health-related items
Types of Medicare Advantage Plans
HMO (Health Maintenance Organization)
The most common type. You select a primary care physician (PCP) who coordinates your care and provides referrals to specialists. You must generally stay within the plan’s provider network except for emergencies.
Best for: Seniors who prefer coordinated care and are comfortable staying within a network.
PPO (Preferred Provider Organization)
More flexibility than HMOs. You can see any doctor or specialist without a referral, including out-of-network providers (at higher cost). No requirement for a PCP.
Best for: Seniors who see multiple specialists or want the freedom to choose any provider.
HMO-POS (Point of Service)
A hybrid plan. You have a PCP and network like an HMO, but you can occasionally go out of network for certain services at higher cost-sharing.
PFFS (Private Fee-for-Service)
You can see any Medicare-approved provider who agrees to the plan’s payment terms. No network restrictions, but providers can decline to accept the plan.
SNP (Special Needs Plans)
Designed for specific populations:
- Dual-eligible SNP — For people with both Medicare and Medicaid
- Chronic Condition SNP — For people with specific conditions like diabetes or ESRD
- Institutional SNP — For people in nursing homes or requiring institutional care
Costs in 2026
| Cost Element | Typical Range |
|---|---|
| Monthly premium | $0 – $50+ (many are $0) |
| Medicare Part B premium | $185.00/month in 2026 (always applies) |
| Annual deductible | $0 – $500 |
| Copays per service | Varies by plan |
| Out-of-pocket maximum | Up to $9,350 (in-network, 2026) |
The out-of-pocket maximum is a key protection. Once you reach it, your plan pays 100% for covered services for the rest of the year. Original Medicare has no out-of-pocket maximum. CMS set the in-network MOOP cap at $9,350 for 2026, up from $8,850 in 2025.
Part D Out-of-Pocket Cap (Inflation Reduction Act)
Starting in 2025, the Inflation Reduction Act capped annual out-of-pocket spending on Part D prescription drugs at $2,000. This applies to all Medicare Part D plans, including those bundled within Medicare Advantage. This is a major cost reduction for seniors with high prescription drug expenses — previously, there was no hard cap on Part D out-of-pocket costs.
Enrollment Periods
Initial Enrollment Period (IEP)
Seven months centered on your 65th birthday (3 months before, your birth month, and 3 months after).
Annual Enrollment Period (AEP)
October 15 – December 7 each year. You can join, switch, or drop a Medicare Advantage plan during this window.
Medicare Advantage Open Enrollment Period
January 1 – March 31 each year. You can switch from one Medicare Advantage plan to another, or switch back to Original Medicare.
Special Enrollment Periods (SEPs)
Triggered by qualifying life events such as moving out of your plan’s service area, losing employer coverage, or qualifying for Medicaid.
Medicare Advantage vs. Original Medicare + Medigap
| Factor | Medicare Advantage | Original Medicare + Medigap |
|---|---|---|
| Monthly premium | Often $0 | Medigap adds $100–$300+ |
| Network restrictions | Usually yes (HMO/PPO) | No network restrictions |
| Out-of-pocket max | Yes ($9,350 in-network, 2026) | Medigap eliminates most costs |
| Extra benefits | Often included | Usually not |
| Provider access | Limited to network | Any Medicare provider |
| Total annual cost | Often lower for healthy | Often lower for frequent care users |
Choosing the Right Plan
When evaluating Medicare Advantage plans, consider:
- Your doctors — Are they in the plan’s network?
- Your prescriptions — Is your medication formulary covered?
- Your health needs — Do you need frequent specialist visits?
- Extra benefits — Does the dental or vision coverage meet your needs?
- Out-of-pocket maximum — What’s the worst-case annual exposure?
