Medicare Part C, also called Medicare Advantage, gives you an all-in-one alternative to Original Medicare by bundling Part A and Part B and often including prescription drug, dental, vision, and hearing benefits.
If you want simpler coverage and extra benefits through a private plan, Medicare Part C lets you get most Medicare services from one insurer instead of separate Parts A and B.
Choosing the right Part C plan affects your costs, care network, and the extra benefits you get, so you need clear guidance.
The Modern Medicare Agency helps you compare plan types, weigh costs and limits, and pick options that match your health needs and budget—our licensed agents are real people you can talk with one-on-one and they find plans without adding extra fees.
As you explore plan types, coverage rules, enrollment windows, and potential trade-offs, The Modern Medicare Agency stands ready to walk you through each step and answer specific questions about providers, networks, and drug coverage.
Stay focused on what matters to you—costs, doctors, and benefits—and let an agent help you narrow the choices.
What Is Medicare Part C?
Medicare Part C, also called Medicare Advantage, gives you an all-in-one plan that replaces Original Medicare Parts A and B.
It often bundles in drug, vision, dental, and hearing coverage and is sold by private insurers approved by Medicare.
Definition and Overview
Medicare Part C (Medicare Advantage) is an alternative to Original Medicare.
You still need Medicare Part A and/or B to join, but the Advantage plan becomes your main coverage.
Plans usually include hospital (Part A) and medical (Part B) benefits, and most add prescription drug (Part D) coverage.
Plans come in several types like HMOs and PPOs.
Each plan sets its own network, costs, and rules for care.
You pay a monthly premium to the plan and still pay any Part B premium billed by Medicare unless the plan covers it.
Medicare monitors and approves these private plans.
How Medicare Advantage Differs From Original Medicare
Original Medicare gives you basic Part A and Part B coverage and lets you see nearly any doctor who accepts Medicare.
Part C replaces that structure.
With Part C, the insurer manages your benefits, provider network, and prior authorization rules.
Many Advantage plans include extra services—like routine dental, vision, and hearing—or a built-in Part D drug benefit.
Out-of-pocket limits exist in Advantage plans; once you reach the annual cap, the plan covers 100% of Medicare-covered services.
Cost sharing, provider choice, and referral rules usually differ from Original Medicare.
Compare provider networks, copays, and total yearly costs before you switch.
Eligibility Requirements
You must be enrolled in Medicare Part A and/or Part B to join a Medicare Advantage plan.
You must also live in the plan’s service area.
Most people become eligible at age 65 or earlier if they qualify for Medicare due to disability.
You cannot have both a Medicare Advantage plan and a Medicare Supplement (Medigap) policy for the same Medicare-covered services.
Special situations—like moving out of the plan area, qualifying for Extra Help, or getting Medicaid—can affect eligibility or allow enrollment changes.
Confirm eligibility specifics with your plan or an agent before applying.
Enrollment Process
You can enroll during specific windows.
The Initial Enrollment Period covers your first eligibility months around your 65th birthday.
The Annual Enrollment Period runs October 15–December 7 each year for plan changes that take effect January 1.
The Medicare Advantage Open Enrollment Period, January 1–March 31, lets current Advantage enrollees switch plans or return to Original Medicare once.
To enroll, compare plans for premiums, deductibles, networks, and drug formularies.
Contact the plan or enroll through Medicare’s website or by phone.
Working with an agent speeds this up: The Modern Medicare Agency’s licensed agents talk with you one-on-one, match plans to your needs, and help you enroll without extra fees.
They explain networks, out-of-pocket caps, and drug coverage so you make a clear choice.
Types of Medicare Part C Plans
Medicare Part C plans vary by how you get care, how much you pay, and which providers you can see.
Know whether you need low premiums, wider provider choice, or flexible provider rules before you enroll.
Health Maintenance Organization (HMO) Plans
HMO plans require you to use a network of doctors and hospitals for most care.
You typically choose a primary care doctor who handles referrals to specialists.
This structure keeps costs predictable with lower monthly premiums and smaller copays for in-network visits.
HMOs often include prescription drug coverage and extra benefits like dental or vision.
Emergency care is covered even outside the network, but routine out-of-network care usually costs more or isn’t covered.
You must live in the plan’s service area to join.
The Modern Medicare Agency helps you compare HMO networks and find one that matches the doctors you prefer.
Our licensed agents speak with you one-on-one to check network coverage and exact costs before you enroll.
Preferred Provider Organization (PPO) Plans
PPO plans give you more flexibility to see providers both in and out of network.
You can see specialists without a referral, though staying in-network lowers your costs.
PPOs usually have higher premiums than HMOs, but they fit people who travel or want wider provider choice.
PPO plans often include Part D drug coverage and extra benefits similar to HMOs.
Out-of-network care is covered at a higher cost share, and you still must live in the plan’s service area.
Cost and coverage rules can vary widely between plans.
The Modern Medicare Agency reviews PPO plan details with you, including in-network provider lists and out-of-pocket limits.
Our agents explain trade-offs so you can choose the PPO that fits your travel and specialist needs.
Private Fee-for-Service (PFFS) Plans
PFFS plans let you see any provider who agrees to the plan’s payment terms.
You do not need a primary care doctor or referrals.
The plan sets how much it pays providers and how much you pay when you get care.
Not all providers accept PFFS terms, so you must confirm provider participation before care.
Costs and coverage rules can change annually, so check plan terms each year.
PFFS plans often include Medicare Part D or offer it as an option.
The Modern Medicare Agency contacts providers and reviews PFFS contract rules for you.
Our licensed agents explain which providers accept the plan and estimate your likely costs, so you avoid surprises.
Benefits and Coverage Options
Medicare Part C bundles hospital and doctor care and often adds drug, dental, and vision coverage.
You get most services through a private plan that sets networks, rules, and costs.
Standard Benefits Included
Medicare Advantage plans include the same core benefits as Original Medicare: inpatient hospital care (Part A) and outpatient services (Part B).
You still get emergency and urgent care, medically necessary surgeries, and skilled nursing coverage when needed.
Plans set rules for networks and prior authorizations, so check if your regular doctors and hospitals are in-network to avoid surprise costs.
Plans also set cost-sharing amounts like copays, coinsurance, and yearly out-of-pocket maximums.
That out-of-pocket limit can protect you from very high bills; Original Medicare has no cap.
You must keep your Part A or Part B enrollment to join a Part C plan.
Additional Services and Extras
Many Part C plans offer extras Original Medicare does not cover.
These often include routine dental cleanings, basic vision exams and glasses, hearing exams and hearing aids, and fitness program memberships.
Some plans add transportation to doctor visits, over-the-counter allowances, or telehealth visits.
Availability and limits vary by plan and county.
For example, one plan might cover two dental cleanings per year, while another covers dentures only after a waiting period.
Review the plan’s Summary of Benefits for exact services, visit limits, and any prior authorization rules.
Prescription Drug Coverage
Most Medicare Advantage plans include Part D prescription drug coverage built into the plan.
This covers many generic and brand-name medicines with tiered copays or coinsurance based on the drug’s formulary tier.
The plan’s formulary lists covered drugs and any step-therapy or prior authorization requirements.
Check yearly changes during open enrollment: formularies, tiers, and pharmacy networks can change.
If you take specialty drugs, confirm coverage and cost-sharing before you switch plans.
The Modern Medicare Agency can connect you with a licensed agent to compare drug coverage, check formularies for your medicines, and find plans that fit your budget without hidden fees.
Our agents speak with you one on one and tailor options to your needs.
Costs Associated With Medicare Part C
Medicare Part C costs vary by plan and location.
You will usually see a mix of monthly premiums, yearly deductibles, limits on what you pay each year, plus copays or coinsurance when you get care.
Premiums and Deductibles
Premiums are the monthly fees you pay to join a Medicare Advantage plan.
Many plans charge $0 monthly premium, but others charge an amount based on the plan’s benefits and where you live.
You still must keep paying your Medicare Part B premium unless a plan states otherwise.
Deductibles are the amount you pay before your plan starts to share costs.
Some Part C plans have no medical deductible; others set a deductible for hospital stays or specific services.
Prescription drug coverage in a Part C plan can have a separate drug deductible.
Check each plan’s Summary of Benefits to see exact premium and deductible numbers for your county.
The Modern Medicare Agency helps you compare premiums and deductible details side-by-side.
Our licensed agents explain what you will pay each month and how deductibles affect your care choices, with no extra fees for that guidance.
Out-of-Pocket Maximums
Medicare Advantage plans must set an annual out-of-pocket maximum for covered medical services.
Once you reach this limit, the plan pays 100% of covered Part A and B services for the rest of the year.
The cap applies only to in-network costs if your plan is an HMO or PPO with network rules, so out-of-network care may not count the same way.
Out-of-pocket maximums differ by plan and can range widely.
Look for the specific dollar limit in the plan’s brochure; it gives you a clear ceiling on how much you can spend for covered services.
Prescription drug costs usually do not count toward the medical out-of-pocket maximum unless the plan states otherwise.
You can talk with a licensed agent at The Modern Medicare Agency to find plans with lower maximums that match your health needs.
Our agents spell out which services count toward the limit so you can avoid surprise bills.
Copayments and Coinsurance
Copayments are fixed fees you pay for visits or services, like $20 per primary care visit or $50 per emergency room visit.
Coinsurance is a percentage of the cost you pay after any deductible, such as 20% of a specialist visit or certain procedures.
Plans list copays and coinsurance for common services in the Summary of Benefits.
Network rules affect these costs.
HMOs often require you to use in-network providers and get referrals for specialists, which can lower copays.
PPOs give more out-of-network flexibility but usually charge higher copays or coinsurance for those visits.
Some plans offer reduced copays for chronic condition programs or preventive care.
The Modern Medicare Agency’s licensed agents walk you through each plan’s copays and coinsurance so you know what you’ll pay for visits, tests, and prescriptions.
You can speak one-on-one with a real person who helps match plan cost structures to your budget.
Comparing Medicare Part C to Other Medicare Options
Medicare Part C bundles hospital and medical coverage and often adds extras like drug, dental, or vision benefits.
It can lower your paperwork and may change how you access doctors and pay costs compared with other Medicare choices.
Part C vs. Original Medicare
Original Medicare (Part A and Part B) pays most hospital and doctor costs but does not include drug coverage or many extras.
With Original Medicare, you can see any provider that accepts Medicare.
You pay Part B premiums, deductibles, and typically 20% coinsurance for many services unless you buy a separate Medigap policy.
Medicare Part C replaces Original Medicare and is sold by private insurers.
Most Part C plans include Part D drug coverage and may add dental, vision, or fitness benefits.
You usually face network rules and need prior authorization for some services.
Cost structure differs: Part C plans often have lower out-of-pocket limits but may require copays, coinsurance, and plan premiums.
If you value fewer bills and extra benefits, Part C may fit.
If you want unrestricted provider access or a Medigap policy, Original Medicare might work better.
Part C vs. Part D Plans
Part D plans only cover prescription drugs.
They work alongside Original Medicare to give you drug coverage.
If you stay with Original Medicare, you can buy a separate Part D plan to cover medications.
Part D premiums, formularies, and pharmacy networks vary by plan.
Many Medicare Part C plans include Part D, so you do not need a standalone drug plan.
Bundled Part C can simplify billing and coordinate medical and drug benefits under one insurer.
Standalone Part D can offer more pharmacy choices if you prefer Original Medicare for provider freedom.
Consider your medication list, preferred pharmacies, and expected yearly costs.

Enrollment Periods and Switching Plans
You need to know when you can join, switch, or leave a Medicare Advantage (Part C) plan and what each window means for your coverage and costs.
Dates, eligibility, and steps matter: missing a period can delay coverage or raise your costs.
Initial Enrollment Period
Your Initial Enrollment Period (IEP) starts three months before the month you turn 65. It includes your birth month and ends three months after that month.
During this seven-month window you can enroll in Original Medicare Parts A and B. You can also join a Medicare Advantage plan (Part C).
If you delay Part B without qualifying for a Special Enrollment Period, you might face late penalties and later start dates.
To sign up for a Medicare Advantage plan during IEP, compare plan networks, drug coverage, premiums, and out-of-pocket limits before your coverage start date. Coverage typically begins the month you enroll in your birth month or later, depending on the exact enrollment month.
If you already have employer coverage, check how joining Part C affects that employer plan.
Annual Enrollment Period
Annual Enrollment Period runs from October 15 to December 7 each year. You can join, switch, or drop a Medicare Advantage plan or a Part D drug plan in this window.
Any changes you make during these dates take effect January 1 of the next year. Use this time to review yearly changes: benefit updates, provider networks, formulary (drug list) changes, and premium shifts.
If your current plan raises costs or drops a needed drug, you can change plans once during this period.
Special Enrollment Situations
Special Enrollment Periods (SEPs) let you make changes outside regular windows when life events occur. Common triggers include moving out of a plan’s service area, losing other credible coverage (like employer or Medicaid), or qualifying for Extra Help with drug costs.
Each SEP has specific time limits—often 60 days from the event—so act fast. Other SEPs apply if you enter or leave a nursing facility, gain or lose Medicaid, or experience changes in eligibility.
If you qualify for a SEP, you can usually switch to a plan that better fits your new situation without waiting for the Annual Enrollment Period.
How to Choose a Medicare Part C Plan
Pick a plan that keeps your doctors, covers medicines you take, and fits your budget. Look closely at networks and covered services so you avoid unexpected bills or denied care.
Evaluating Provider Networks
Check whether your primary doctors and specialists are in the plan’s network. If you want to keep a current doctor, call both the plan and the doctor’s office to confirm in-network status for your zip code.
Note plan types: HMOs usually require a primary care referral and limit out-of-network care. PPOs let you see out-of-network providers but at higher cost.
Ask about prior authorization rules for tests or procedures you expect to need. Use the plan’s provider directory and verify facility coverage for hospitals you prefer.
Also check telehealth availability if you use virtual visits. If you travel often, confirm emergency and urgent care rules outside your home area.
Considering Coverage Needs
List your regular prescriptions, recent medical services, and any planned procedures. Compare each plan’s drug formulary and tiered copays to see which saves you the most on the meds you actually take.
Look at extra benefits beyond Original Medicare: dental, vision, hearing, fitness, and transportation. Decide which extras matter to you and compare the monthly premiums plus expected out-of-pocket costs like copays and deductibles.
Potential Drawbacks and Limitations
Medicare Part C can save money and add benefits, but it often limits which doctors you can see and may require approval before certain services. These two issues can affect how quickly and easily you get care and how much you pay at the time of service.
Network Restrictions
Medicare Advantage plans usually use provider networks like HMOs or PPOs. If you see a doctor outside the plan’s network, you may pay higher costs or the visit may not be covered at all.
Always check whether your current doctors and preferred hospitals are in the plan’s network before you enroll. Networks can change each year.
A provider you see now might leave the network next year, so review network rosters during open enrollment. For travel or seasonal living, verify how the plan covers out-of-area care and whether you need referrals to see specialists.
Prior Authorization Requirements
Many Medicare Advantage plans require prior authorization before approving services, tests, or certain drugs. Prior authorization means the plan must agree in advance that the service is medically necessary.
If you don’t get approval, the plan may deny payment and leave you responsible for the bill. Common services that need prior authorization include specialty imaging (like MRIs), certain surgeries, and some high-cost medications.
Prior authorization can delay care because your provider must submit documentation and wait for a decision. Know the plan’s typical turnaround times and appeals process.
You can avoid surprises by choosing plans with simpler authorization rules for your chronic conditions.
