Key Takeaways
- Medicare Advantage plans are private insurance alternatives to Original Medicare that often include prescription drug coverage and extra benefits like dental and vision
- Most plans have $0 monthly premiums, but you’ll still pay Medicare Part B premiums plus copays and deductibles when you use services
- Plans operate through provider networks (HMO, PPO) and may require referrals for specialists depending on the plan type
- You can only enroll during specific periods: October 15 – December 7 (Annual Enrollment) or when you first get Medicare
- Medicare Advantage caps your annual out-of-pocket costs, unlike Original Medicare which has no limit
What Are Medicare Advantage Plans?
Medicare Advantage plans are private health insurance plans approved by Medicare that provide all the benefits of Original Medicare (Parts A and B) plus additional coverage in a single plan. Also known as Medicare Part C, these plans are offered by private insurance companies like Humana, Anthem, and UnitedHealthcare.
Unlike Original Medicare, which allows you to see any doctor who accepts Medicare, Medicare Advantage plans typically use provider networks. This means you'll generally pay less when you see doctors and visit hospitals within your plan's network. Most plans also include prescription drug coverage (Medicare Part D) and extra benefits like dental, vision, hearing aids, and wellness programs that Original Medicare doesn't cover.
The key difference is that with Medicare Advantage, you're getting your Medicare benefits through a private insurer rather than directly from the federal government. These companies receive payments from Medicare to provide your coverage and often add extra benefits to attract members. For a comprehensive overview of how these plans work, see our detailed guide on Medicare Part C (Medicare Advantage).
What Do Medicare Advantage Plans Cover?
All Medicare Advantage plans must cover everything Original Medicare covers. Most plans go further by including valuable extras:
Required Benefits
- Hospital stays (Part A)
- Doctor visits & outpatient services (Part B)
- Preventive care (annual wellness visits, screenings)
- Emergency & urgent care (nationwide)
Common Extras
- Prescription drug coverage (96% of plans)
- Dental, vision & hearing coverage
- Fitness memberships & wellness programs
- OTC allowances, telehealth, transportation
Some plans offer special benefits like the Give Back Benefit that reduces your Medicare Part B premium, or grocery allowances for members with chronic conditions. Benefits vary significantly between plans, so it's important to compare what's included in plans available in your area.
Types of Medicare Advantage Plans
There are several types of Medicare Advantage plans, each with different rules for accessing care:
You must choose a primary care doctor and get referrals to see specialists. Lowest costs but least flexibility.
You can see any provider but pay less for in-network care. No referrals needed for specialists.
The plan sets payment rates for providers. You can see any doctor who accepts the plan’s terms.
Designed for people with chronic conditions, institutional care needs, or dual Medicare/Medicaid eligibility.

How Much Do Medicare Advantage Plans Cost?
Medicare Advantage plans often have attractive pricing, but costs come in several forms:
| Cost Type | Typical Amount (2026) |
|---|---|
| Monthly Premium | $0 for most plans (85%+) |
| Part B Premium (required) | $185/month |
| Primary Care Visit | $0–$25 copay |
| Specialist Visit | $35–$50 copay |
| Hospital Stay | $200–$400/day (first few days) |
| Out-of-Pocket Maximum | $8,850 or less (in-network) |
While the $0 premium is appealing, your total costs depend on how much care you use. Compare the total estimated costs, not just premiums. For a detailed cost breakdown, see our Medicare Advantage costs guide.
Pros and Cons of Medicare Advantage
Advantages
- Lower monthly premiums (often $0)
