Medicare Advantage changes how you receive Medicare benefits, not whether you have Medicare.
You remain enrolled in Medicare and must have both Part A and Part B. The plan administers your Medicare-covered care and becomes the primary card you use for most services.
Medicare Part A and Part B
You keep Medicare and continue paying the Part B premium. You should keep your red, white, and blue Medicare card in a safe place.
A Medicare-approved private plan
The plan sets its network, service area, cost sharing, referral rules, authorization requirements, and any additional benefits within Medicare requirements.
Part A and Part B benefits
Plans cover all emergency and urgent care and almost all medically necessary services Original Medicare covers.
Prescription drug coverage
Most plans include Part D. Formularies, pharmacies, tiers, restrictions, and drug costs remain plan-specific.
Additional benefits
A plan may include dental, vision, hearing, fitness, transportation, allowances, or other benefits with limits.
Important: A low or $0 plan premium does not mean the coverage is free. You generally keep paying your Part B premium and may owe deductibles, copayments, or coinsurance when you use care.
The plan type helps determine how you access care.
HMO and PPO plans are common, but Medicare Advantage also includes other structures. Select a plan type to see the questions that matter most.
A defined network with coordinated care.
You generally receive non-emergency care from the plan’s network. Most HMOs ask you to choose a primary care doctor, and referrals are commonly required for specialists.
Verify every important doctor, hospital, and medical group before enrolling.
Who has contracted with the plan?
Confirm doctors, hospitals, labs, facilities, and medical groups directly with the plan and provider.
Who coordinates specialist access?
Some plans require a primary care referral before certain specialist visits; others generally do not.
What needs plan approval first?
Certain services or supplies may need approval before the plan covers them. Ask how ongoing treatment is handled.
Look beyond the premium and map the full year.
Medicare Advantage costs vary by plan and can change each year. A useful comparison includes both predictable monthly expenses and the costs you may pay when you use care.
Fixed expenses
- Part B premium
- Plan premium, if any
- Income-related Part D adjustment, if applicable
Service costs
- Deductibles
- Doctor and specialist copays
- Hospital, imaging, therapy, and drug costs
Out-of-pocket limit
- Varies by plan
- Applies to covered Medicare health services
- Drug spending follows separate Part D rules
The medical out-of-pocket limit does not include every expense. Review the plan’s Evidence of Coverage for what counts toward the limit and how prescription drug costs are handled.
Turn your preferences into a plan-review strategy.
This tool does not recommend a specific plan. It identifies the areas that deserve the closest review based on how you prefer to receive care.
Answer the six questions to organize your plan review.
Your result will highlight which parts of a Medicare Advantage plan deserve the most attention.
Doctor and hospital network review.
Routine care outside the service area.
Premiums, service costs, and annual exposure.
Formulary, pharmacy, and restriction review.
Referrals, network use, and authorizations.
Limits, providers, allowances, and frequency.
This educational tool does not determine plan eligibility, suitability, or enrollment. Available plans and benefits depend on your ZIP code, eligibility, and the plan year.
Drug coverage and additional benefits require their own review.
Two plans can use the same broad labels but cover your prescriptions and additional services very differently.
Prescription drug coverage
- Is every medication on the formulary?
- Which tier applies, and can the tier change?
- Are prior authorization, step therapy, or quantity limits used?
- Which pharmacies are preferred, standard, or out of network?
Additional plan benefits
- What services are covered and how often?
- Is there an allowance or plan maximum?
- Must you use a specific network or vendor?
- Does unused value expire?
Verify the plan around your real life, not its headline benefits.
Check each item directly against the plan’s current documents, provider information, pharmacy information, and your own needs.
Emergency coverage travels differently than routine care.
Medicare Advantage plans cover emergency and urgent care, but routine non-emergency access outside the plan’s service area depends on the plan type and rules.
A good plan today still deserves an annual review.
Benefits, provider networks, drug formularies, pharmacies, premiums, and cost sharing can change for the next year.
Mark every change that affects your care or costs.
Compare the coming year before the decision window opens.
Keep your plan or make an allowed change for January 1.
Check ID cards, providers, prescriptions, and first appointments.
Do not review only the additional benefits. Start with doctors, prescriptions, access rules, and total annual cost exposure. Then compare dental, vision, hearing, fitness, allowances, and other additions.
Four Medicare Advantage assumptions worth correcting.

Assumption “A $0 premium plan means I will have no costs.” Click to reveal the clearer rule
You generally keep paying the Part B premium and may owe deductibles, copayments, coinsurance, prescription costs, and charges for services the plan does not cover.
Assumption “If my doctor accepts Medicare, the doctor accepts every Medicare Advantage plan.” Click to reveal the clearer rule
Medicare participation and Medicare Advantage network participation are different. Verify the specific plan, doctor, location, medical group, and hospital affiliation.
Assumption “All dental, vision, and hearing benefits work the same.” Click to reveal the clearer rule
Plans may use different networks, allowances, frequency limits, copayments, covered services, vendors, and exclusions. Compare the rules, not only the benefit label.
Assumption “Once I choose a plan, I do not need to review it again.” Click to reveal the clearer rule
Plans can change costs, benefits, provider networks, formularies, and pharmacy arrangements. Review the Annual Notice of Change and your needs every year.
