Medicare Advantage Plans

Western Wind Insurance & Investments is here to help you weigh your Medicare coverage options.

What is a Medicare Advantage (Part C) Plan?

Medicare Advantage (Part C) plans are a combined alternative to Original Medicare. Offered by private insurance companies approved by Medicare, these plans bundle:


  • Part A (hospital)
  • Part B (medical)
  • Often Part D (prescription drugs)
  • Sometimes additional benefits, depending on the plan


When you enroll in a Medicare Advantage plan, your Medicare benefits are managed through the private plan, not through Original Medicare directly. But you're still part of the Medicare program.

Types of Medicare Advantage Plans

There are several types of Medicare Advantage plans, each with its own rules:

  • Health Maintenance Organization (HMO)
    Must use the plan's network providers (except in emergencies); referrals often required.

  • Medicare Medical Savings Account (MSA)
    Combines a high-deductible plan with a Medicare-funded savings account; usually no defined network. Must purchase a standalone Part D Prescription Drug Plan.

  • Preferred Provider Organization (PPO)
    Plan covers in-network providers, and out-of-network providers at a higher cost; no referrals needed.

  • Private Fee-for-Service (PFFS)
    You can see any Medicare-approved provider who agrees to the plan’s payment terms, which decide how much it will pay providers and how much you will pay.

  • Special Needs Plan (SNP)
    Designed for people with specific health conditions, dual eligibility for Medicare and Medicaid, or those living in certain facilities.

Important Note: Availability of specific plan types and networks may vary by state and region.

Key Features: Medicare Advantage Plans

Bundled Coverage

Most plans include hospital, medical, and prescription drug coverage in one plan.


Extra Benefits (Varies)

Many plans include other benefits. Varies by carrier and plan, so check plan details.


Cost Predictability

Some plans have lower deductibles or $0 premiums and include annual out-of-pocket maximums, which Original Medicare does not.


Coordinated Care

Many Medicare Advantage plans, such as HMOs or PPOs, operate under managed care models and can provide coordinated care options for beneficiaries. These plans may require you to choose a primary care physician and obtain referrals to see specialists.


Flexibility in Provider Choice (Varies)

Some plans offer flexibility to see out-of-network providers, often for a higher cost. This may allow for continuity of care with current healthcare providers.


Medicare Star Ratings

Plans are rated on a 5-star scale based on quality of care, customer service, and member satisfaction, making it possible to find a highly-rated plan.

Choosing a Medicare Advantage Plan

When selecting a Medicare Advantage plan, it's essential to consider your individual healthcare needs, including additional benefits/coverage, prescription drug coverage, provider networks, and out-of-pocket expenses. Here are some factors to evaluate:


  • Costs: Compare the monthly premiums, deductibles, copayments, coinsurance, and out-of-pocket maximums for each Medicare Advantage plan for your desired coverage.

  • Coverage Needs: Review the plan's benefits to ensure they align with your healthcare needs, including coverage for prescription drugs and other services.

  • Prior Authorization: Consider requirements for prior authorization (PA). Most Advantage plans require PA for specialist care, diagnostic imaging, etc. Be sure you understand these guidelines to avoid delaying care.

  • Plan Ratings: Plans are officially rated on a 5-star scale based on quality of care, customer service, and member satisfaction. Use plan ratings (found in Medicare.gov’s plan finder tool) to gauge the quality and performance of the plan.

  • Prescription Drug Coverage: Ensure your prescription drugs are included in the plan’s formulary (list of covered medications), and that the plan’s preferred pharmacies are convenient for you.

  • Provider Network: Determine if the plan’s network includes, or is accepted by, your preferred healthcare providers (primary doctor, specialists, etc.)

Enrolling in a Medicare Advantage Plan

You can join, switch, or drop a Medicare Advantage plan during:


  • Annual Enrollment Period (AEP): October 15 to December 7 every year; change, switch, or leave plans.

  • Initial Coverage Election Period (ICEP): Seven-month window to sign up for a Medicare Advantage plan; starts three months before your 65th birthday month and ends three months after.

  • Medicare Advantage Open Enrollment (OEP): January 1 to March 31 every year; switch Advantage plans or return to Original Medicare (but you can’t join a new Advantage plan during this period).

  • Special Enrollment Periods (SEPs): Certain life events (moving, losing coverage, etc.) may qualify you to change enrollment.

Medicare Advantage Frequently Asked Questions

  • Can I switch from Original Medicare (with a Medigap plan) to Medicare Advantage (or vice versa)?

    In some cases yes, but timing matters. Moving from Medigap (with Original Medicare) to an Advantage plan is usually easier than switching the other way (due to medical review, also called underwriting). For timing, see the enrollment section above.
  • Are all Medicare Advantage plans the same?

    No. Plans vary by state, county, and provider network. That’s why local guidance from professional advisors is key.
  • Do Advantage plans include drug coverage?

    Most do, but not all. You’ll want to verify if the plan includes Part D coverage, and if it doesn’t you may need to enroll (and pay) separately in a Medicare Part D plan. Some beneficiaries may choose an Advantage plan without Part D if they get prescription drug coverage from another entity (such as the VA for veterans).
