Medicare Care Advantage (Part C) Plans

Medicare Part C, or Medicare Advantage, exists as another way to deliver the benefits of  Original Medicare Parts A and B. Medicare Advantage plans bundle Medicare Part A, Part B, and usually Part D. These plans must cover the same care and services as Part A and Part B, but may also include coverage for additional services like dental, vision, and auditory care.

Medicare Advantage, also known as Medicare Part C, is a part of Medicare, which is the federal healthcare plan for the following groups:

  • Individuals age 65 and older
  • Certain individuals younger than 65 with disabilities

To understand what Medicare Part C is, it’s helpful to first understand what Medicare is. Medicare, which may also be referred to as Original Medicare, consists of two parts:

Part A (Hospital Insurance): Covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home healthcare.

Part B (Medical Insurance): Covers outpatient care, preventative care, certain doctors’ services, and medical supplies.

Prescription drug coverage, also known as Part D, is provided by private insurers and provides prescription drug plans (PDP) to individuals on Medicare.

Medicare Part C, or Medicare Advantage, exists as another way to deliver the benefits of  Original Medicare Parts A and B. Medicare Advantage plans bundle Medicare Part A, Part B, and usually Part D. These plans must cover the same care and services as Part A and Part B, but may also include coverage for additional services like dental, vision, and auditory care.

When an individual has health insurance via Medicare Advantage, the insurance company pays for the services, not Medicare. Because Medicare Advantage plans are underwritten by insurance companies, they can offer certain features that Original Medicare cannot, such as out-of-pocket spending caps.

Whether you stay with Original Medicare or add a Medicare Advantage plan depends on your unique circumstances, healthcare needs, and budget. Below, we give an overview of Medicare Advantage plans, providers, benefits, and eligibility criteria.

Who is eligible for Medicare Part C?

Generally speaking, anyone who is eligible for Original Medicare is eligible for Medicare Advantage. Individuals who are 65 and older are eligible for Medicare, as are individuals younger than 65, but who have certain disabilities. If you already have Medicare Part A and Part B, you are most likely eligible for Medicare Part C. You can also use Medicare’s online tool to determine your eligibility for Medicare.

Great news for those having End Stage Renal Disease (ESRD), as of January 2021 ESRD is no longer considered for enrollment in Medicare Advantage Plans. However, in some areas there are still Special Needs Plans which cater to its related issues.  Also, individuals who have Medicare Supplemental Insurance, also known as Medigap, cannot enroll in a Medicare Advantage plan unless they drop their Medigap coverage.

What does Medicare Part C cover?

While Original Medicare plans have fixed costs for premiums, deductibles, and coinsurance, the costs associated with Medicare Part C vary based on the insurance provider and plan.

When it comes to the cost of Medicare Part C plans, there are a few other things to keep in mind.  While many Medicare Advantage plans do not have deductibles, those that do can vary widely. Regardless of the deductible, most Medicare Advantage plans use copayments or coinsurance. Copayments will allow you to know upfront how much you will be expected to pay after you meet your deductible. Coinsurance for payments beyond the deductible means the amount you will pay out-of-pocket depends on the overall cost of the service provided. Many Medicare Advantage plans will use deductibles for prescription drug coverage.

Also, Medicare Advantage plans, unlike Original Medicare plans, have an out-of-pocket spending cap. Once you reach that limit for the year, all other costs for Part A and Part B services will be 100% covered.

How does Medicare Part C work?

If you decide to enroll in a Medicare Advantage plan, you will have a few different types of plans to choose from. The exact availability of plans will depend on the health insurance provider, and your geographic location. Some of these plan types may be familiar to you if you previously had private health insurance through an employer. Your needs will ultimately determine which type of plan is right for you.

HMO Plans

A Health Maintenance Organization (HMO) plan gives users access to certain doctors and hospitals within its network. This provider network has agreed to give HMO customers lower rates. However, if you visit a non-network provider, it will likely not be covered, and you will have to pay those fees out of pocket. With some Medicare Advantage HMO plans, out-of-network exceptions may be made for emergency care, out-of-area urgent care, and out-of-area dialysis.

Medicare HMO Plan Key Facts

Overview

Some HMO plans have a Point-of-Service (POS) option, which lets customers go out-of-network for certain services, although in-network services may be less expensive. HMO plans usually offer benefits not included in Original Medicare, although these benefits may cost extra.

Prescription Drug Coverage?

Yes, prescription drugs are typically covered with HMO plans, but confirm with the plan. If you choose an HMO plan without drug coverage, you will not be allowed to join a stand alone Part D plan.

Primary Care Doctor?

Yes, in most cases, with an HMO plan, you must choose an in-network primary care doctor.

Referrals?

Yes, in most cases you must have a referral to see a specialist, although certain services (like yearly mammogram screenings) do not require a referral.

Out-of-Network Care?

If you get healthcare outside of your plan’s network, you may be responsible for the full cost of the services.

PPO Plans

A Preferred Provider Organization (PPO) plan works similarly to an HMO, in that there is a network of approved providers, but customers have more flexibility to go outside of that network for care. Additionally, a PPO plan may cover some of the cost if you see a non-network provider. Compared to HMO plans, a PPO plan may have higher premiums as well as a deductible.

Medicare PPO Plan Key Facts

Overview

PPO plans usually offer additional benefits not included with Original Medicare plans, although these benefits may cost extra.

Prescription Drug Coverage?

Yes, prescription drugs are typically covered with PPO plans, but confirm with the plan. If you choose a PPO plan without drug coverage, you will not be allowed to join a stand alone Part D plan.

Primary Care Doctor?

No, you do not need to choose a primary care doctor with a PPO plan.

Referrals?

No, in most cases, with a PPO plan, you do not need to get a referral to see a specialist. However, if you use in-network specialists, your costs will be lower than using out-of-network specialists.

Out-of-Network Coverage?

With a PPO plan, you can go to in-network or out-of-network healthcare providers, although the out-of-network providers will typically cost more.

PFFS Plans

Medicare Private Fee-For-Service (PFFS) plans offer customers flexibility, in that they do not require primary care doctors or referrals. However, because of the way PFFS plans’ reimbursement structure works, doctors and other healthcare providers may choose not to accept patients with a PFFS plan. With a PFFS plan, the insurance company determines how much it will pay doctors and healthcare providers, and how much the customer will pay within the limits set by CMS.

Medicare Plan PFFS Key Facts

Overview

Doctors, hospitals, and other healthcare providers can decide on a case-by-case basis whether to accept your PFFS plan.

Prescription Drug Coverage?

It depends on the plan. If your plan does not include prescription drug coverage, you can get coverage through Medicare Prescription Drug Plan Part D.

Primary Care Doctor?

No, you do not need to choose a primary care doctor.

Referrals?

No, you do not need referrals to see specialists.

Out-of-Network Coverage?

Depending on the PFFS plan, there may be a network of healthcare providers who have agreed to always treat plan members. In that case, they must accept you for treatment and their charges will be lower than out-of-network providers. Other plans may not have a network, but allow customers to get care from any doctor or healthcare provider who accepts the plan’s terms.

SNP Plans

Special Needs Plans (SNP) are specifically designed for people with specific diseases or characteristics. These types of plans allow users to tailor their benefits, provider choices, and drug formularies to best meet their needs. Eligibility for SNPs is restricted, compared to HMO and PPO plans that are open to anyone who meets the basic eligibility criteria for Medicare. The availability of Medicare SNPs varies by location.

Medicare SNP Plan Key Facts

Overview

Medicare SNPs are required to cover the same Medicare services as all Medicare Advantage plans, but also include extra services tailored to the specific needs of the customers they served, based on their conditions.

Prescription Drug Coverage?

Yes, all SNPs provide Medicare prescription drug coverage.

Primary Care Doctor?

Yes, in most cases, an SNP will require that you have a primary care doctor, or a care coordinator to help oversee your healthcare.

Referrals?

Yes, in most cases, an SNP will require that you get referrals for specialist care, although certain services, like yearly mammogram screenings, are exempt.

Out-of-Network Coverage?

Generally, SNP members must get care from doctors or hospitals in the Medicare SNP network, although certain services, like emergency or urgent care, and out-of-area dialysis for ESRD patients, are exempt.

MSA Plans

A Medicare Medical Savings Account (MSA) is similar to a Health Savings Account (HSA). This type of plan combines a high-deductible insurance plan with a medical savings account that customers can use to pay their healthcare costs. Medicare provides the money that goes into your medical savings account. Once you reach your deductible, the plan will cover your Medicare-covered services. However, if you run out of money in your medical savings account before you reach your deductible, you must pay the difference for healthcare costs out-of-pocket.

Medicare MSA Plan Key Facts

Overview

Unused funds in your medical savings account roll over from year to year.

Prescription Drug Coverage?

No, Medicare MSA plans do not include prescription drug coverage. Customers must join a Medicare Part D prescription drug plan for this type of coverage.

Primary Care Doctor?

Dependent on the individual plan.

Referrals?

Dependent on the individual plan.

Out-of-Network Coverage?

Dependent on the individual plan.

How to apply for Medicare Part C?

First, you must be enrolled in Original Medicare Parts A and B before you can enroll in a Medicare Advantage plan. Those eligible to enroll in Original Medicare, include:

  • Individuals turning 65: The three months prior to turning 65, the month you turn 65, and the three months after you turn 65 is considered the Initial Enrollment Period (IEP).
  • Individuals under 65 with a disability and receiving disability payments through Social Security or the Railroad Retirement Board.

For most people, Medicare Advantage plan enrollment occurs at the same time as their Initial Enrollment Period to Original Medicare. That said, there are additional enrollment periods throughout the year to be aware of:

  • Annual Enrollment Period (October 15-December 7): During this period, a person on Original Medicare with no Advantage plan can enroll in an Advantage plan or those currently enrolled in an Advantage plan can switch to another Advantage plan or return to Original Medicare.
  • Medicare Advantage Open Enrollment Period (January 1-March 31): During this period, those currently enrolled in a Medicare Advantage plan can switch plans or return to Original Medicare. Those on Original Medicare cannot join an Advantage during this period.
  • General Enrollment Period (April 1-June 30): This period is for enrollment in Original Medicare for those who missed their Initial Enrollment Period (IEP). Enrollment in Medicare Advantage can coordinate with this period.

Individuals who do not sign up for Medicare benefits during these time frames may face penalties, with the exception of people who are actively employed and receiving health insurance from their employer or involved in qualified overseas volunteerism. If you are approaching age 65 and are still working, consult with your employer to find out if your coverage will continue, or if you will need to switch to a Medicare plan. You will also be able to join Original Medicare or Medicare Advantage during a special enrollment period if your employment situation changes.

Again, because Medicare Advantage plans are offered by individual insurance companies, the enrollment processes will differ depending on the carrier. Generally, you can follow the steps below to enroll in a Medicare Advantage plan:

  1. Visit Medicare’s Plan Finder to find available plans in your area.
  2. Comparison shop plans based on your needs and budget.
  3. When you select the plan in which you would like to enroll, follow their instructions for completing an enrollment application. Many plans will allow you to fill out the application online, although all plans are required to offer an option for a paper enrollment form.

When you sign up for a Medicare Advantage plan, you will need to provide your Medicare number, as well as the date your Medicare Part A and Part B coverage began.

Should I get Medicare Part C?

Whether you should enroll in a Medicare Part C plan depends on a variety of factors that are unique to you. Keep in mind that it is also possible to switch Medicare Advantage plans during enrollment periods, if you find your current plan does not meet your needs.

Here are some things to consider when deciding if Medicare Part C is right for you:

How to choose the best Medicare Advantage Plan for your needs

Step 1: Find plans available in your area

The Medicare Advantage plans that are available to you depend on where you live, so the best place to start your selection process is by using the Medicare Advantage Plan Finder Tool to see your options.

Once you enter your zip code and answer a few questions, the Plan Finder will show you all the available Medicare Advantage plans in your area.

Step 2: Identify your healthcare needs and priorities

You can also do this before you start your search, but either way, it’s necessary to identify your specific needs and priorities when shopping for plans. The following questions can help you determine what your needs and priorities are:

  • How is your overall health? Do you have chronic conditions that require specialists’ care and medications, or are you generally healthy, and just need routine preventive care?
  • What prescription drugs do you currently take?
  • Do you want or need a plan that includes dental, vision, and/or hearing coverage?
  • Do you want or need a plan that includes services like fitness memberships, ambulance services, coverage outside the U.S., and other perks?

Step 3: Determine your budget

Because private insurance companies offer Medicare Advantage plans, their cost can vary widely, based on your home state, the plan provider, plan type, and plan benefits.

Costs associated with Medicare Advantage plans include premiums, deductibles, copays, and coinsurance. For plans that include prescription drug coverage, you’ll pay additional deductibles, copays/coinsurance costs. All plans of out-of-pocket spending limits.

The Plan Finder Tool lets you sort plans based on lowest monthly premium, lower drug deductible, lowest health plan deductible, and lowest drug and premium cost.

Expert Tip: If you aren’t up to the task of digging through plans on your own, find a qualified Medicare broker or agent to help you navigate your choices. Find one with at least two to five years’ experience with Medicare insurance and be sure they are contracted to sell multiple plans available in your area, which allows them to work for you. In most cases there is no charge for a broker’s services, but always check before scheduling an appointment.

Step 4: Look for networks that include your doctors

When you are looking at plans through the Plan Finder Tool, you will be able to view a directory of in-network providers for each individual plan. If you already have doctors that you would like to continue seeing, verify that they are within the plan’s network of providers, so you can avoid paying out-of-network costs to see them.

Step 5: Decide which kind of plan you want

As mentioned previously, Medicare Advantage offers several different types of plans, including HMO, PPO, PFFS, SNP, and MSA plans. Price, services included, and networks will all vary by plan. Whether your doctors are in-network or out-of-network may also influence your decision of which type of plan works best for you.

Step 6: Compare ratings for plans

The Centers for Medicare and Medicaid Services (CMS) does an annual review of Medicare Part C and Part D plans, and publishes scores on a five-star scale. These scores can help you assess the quality of plans you are considering. The CMS Five-Star Rating System evaluates plans on the following points:

  • Availability of health screenings, tests, and vaccines
  • Management of chronic health conditions
  • Member experience with health plan
  • Plan performance and member complaints
  • Customer service availability and experience
  • Drug pricing, safety, and accuracy

Each plan receives a score for each of these categories, an individual star rating for Part C and Part D, and an overall score. Checking these scores can help you confirm the quality of the plan you select.

Step 7: Select a plan, and follow instructions for enrollment

Once you have found a plan that works for your needs and budget, follow the provider’s instructions for enrollment. This typically involves completing an online or paper enrollment form. Remember, if you have questions about a plan or its coverage, you should contact a representative to get all your questions answered before signing up for a Medicare Advantage plan.
