Understanding Medicare Advantage Plans
Medicare Advantage plans (Part C) are private insurance alternatives to Original Medicare that bundle hospital, medical and often prescription drug coverage into a single plan. These plans must cover everything Original Medicare does but frequently include extra benefits like dental, vision and hearing coverage.
- CMS Star Ratings: Medicare rates plans on a 1-5 star scale based on quality and performance. Plans with 4 stars or higher demonstrate strong customer satisfaction, effective care management and reliable service.
- Monthly Premiums: You'll pay your Part B premium plus any additional plan premium. Many Medicare Advantage plans charge $0 in additional monthly premiums, though costs vary by coverage level and your location.
- Maximum Out-of-Pocket (MOOP) Limits: These caps protect you from excessive medical costs by limiting your annual spending on covered services. Once you reach your MOOP limit, your plan covers 100% of covered services for the rest of the year.
- Drug Coverage: Most Medicare Advantage plans include prescription drug coverage (Part D) built into the plan. Check your plan's formulary to confirm your medications are covered and understand any restrictions or prior authorization requirements.

While California's 13 PPO Medicare Advantage plans cost more than HMO options, they provide greater freedom in choosing healthcare providers.

| Aetna | 4.50 | $53 | $6,050 | 2 | 4.28 |
| UnitedHealthcare | 3.50 | $120 | $6,700 | 1 | 3.50 |
PPO plans usually have higher premiums but give the most flexibility by letting you see any provider without referrals, though staying in-network saves money. Choose a PPO if you travel frequently, want access to specialists without primary care physician approval or have established relationships with out-of-network doctors.
How to Choose the Best California Medicare Advantage Plan
Selecting the right Medicare Advantage plan depends on your healthcare needs, budget and preferred level of provider flexibility. Consider these key factors when comparing plans in California:
- 1Confirm That Your Doctors and Hospitals Are In-Network
Call your current providers to confirm they accept the specific plan you're considering, not just the insurance company. Networks vary between plans, even from the same insurer.
- 2Compare Total Costs, Not Just Premiums
A $0 premium plan might cost more overall if it has high copays and out-of-pocket maximums. Calculate your expected annual costs based on your usual healthcare usage, including regular medications and specialist visits.
- 3Evaluate Prescription Drug Coverage
Verify your medications are covered under the plan's formulary and check which tier they're in. Higher tiers mean higher copays, and some plans require prior authorization for certain drugs.
- 4Consider Different Plan Types
There are several plan types to consider. Choose an HMO if you rarely see specialists and want lower costs. Pick an HMO-POS if you need occasional out-of-network access. Select a PPO if you travel frequently or want unrestricted specialist access.
- 5Review Star Ratings and Quality Metrics
CMS star ratings reflect customer satisfaction, care quality and plan administration. Plans with 4.0 stars or higher deliver better service and health outcomes.
- 6Assess Extra Benefits
Many California Medicare Advantage plans include dental, vision, hearing, fitness memberships and over-the-counter allowances. Compare which extras matter most for your lifestyle and health needs.
- 7Understand Out-of-Pocket Maximums
Out-of-pocket maximums cap your annual spending on covered services. Lower maximums provide better financial protection if you face serious illness or injury, though they typically come with higher premiums.

Best California Medicare Advantage: FAQ
Here are quick answers to common questions about enrolling in Medicare Advantage, understanding coverage and navigating enrollment periods in California.
How do you get a Medicare Advantage plan in California?
You can enroll during the Annual Enrollment Period (Oct. 15 to Dec. 7) or when you first become eligible for Medicare. Visit Medicare.gov to compare plans, call insurers directly or work with a licensed insurance agent. Coverage usually starts Jan. 1 for fall enrollments or the first day of the month after you sign up during other qualifying periods.
What does Medicare Advantage cover?
Medicare Advantage plans cover everything Original Medicare does, including hospital stays (Part A) and doctor visits (Part B), plus most include prescription drug coverage (Part D). Many California plans add dental, vision, hearing, fitness memberships and over-the-counter allowances. You'll still pay Medicare Part B premiums plus any additional premium your Medicare Advantage plan charges.
What’s the difference between Medicare Advantage and Medicare Supplement?
Medicare Advantage replaces Original Medicare with a bundled plan from a private insurer that includes medical coverage and often prescription drugs. Medicare Supplement (Medigap) works alongside Original Medicare to help pay deductibles and copays. Medicare Advantage uses provider networks, while Medicare Supplement lets you see any doctor who accepts Medicare.
When is open enrollment for Medicare Advantage in California?
The Annual Enrollment Period runs from Oct. 15 to Dec. 7 each year. California also has a Medicare Advantage Open Enrollment Period from Jan. 1 to March 31 for people already enrolled in Medicare Advantage plans. New Medicare beneficiaries get a seven-month Initial Enrollment Period around their 65th birthday.
Our Methodology: How We Ranked California's Best Medicare Advantage Plans
We analyzed Medicare Advantage plans in California using a weighted scoring system that prioritizes affordability and quality. Our methodology evaluates three main factors to help you identify plans that deliver the best value for your healthcare needs.
- Affordability (50%): Cost makes up half of our overall score, because it directly impacts your budget. We evaluated monthly premiums for Part C and Part D coverage combined (30% weight) and in-network maximum out-of-pocket limits (20% weight). Plans with lower premiums and MOOP amounts score higher, since they reduce your total annual healthcare spending.
- Star Ratings (40%): CMS star ratings measure plan quality across categories like care effectiveness, customer service and member satisfaction. The Overall Star Rating combines both Part C (medical coverage) and Part D (prescription drug) ratings on a scale from 1 to 5 stars. Higher-rated plans earn better scores in our analysis.
- Availability (10%): We factor in how many states each provider operates in, including Washington, D.C. Providers with broader geographic availability score higher because they're more likely to maintain coverage if you move and typically have more resources for customer support and plan improvements.
This scoring system helps you compare plans objectively while accounting for the factors that matter most, including what you'll pay and the quality of care you'll receive.
