What is Medicare?

Medicare is available to U.S citizens or permanent residents aged 65 or older, those under age 65 with a qualified disability receiving SSDI benefits for at least 24 months, and people diagnosed with ALS or ESRD. As a health insurance plan provided by the federal government, it plays an important role in some coverage of medical costs.

Medicare is divided into different plans to help offer more choices in cost and coverage. Learn more about Medicare plans available to you.

Medicare Plans
Medicare Plan Description
Original Medicare A fee-for-service health plan that is divided into two parts. Part A (Hospital Insurance) and Part B (Medical Insurance). The insured is responsible for paying his or her share of coinsurance and deductibles after Medicare pays its share of Medicare approved amounts.
Medicare Part A Hospital insurance that covers inpatient hospital stays, home health, hospice and skilled nursing facilities (with the exception of custodial care).
Medicare Part B Medical insurance that covers services considered to be medically necessary. Those services include preventive care, doctor visits, durable medical equipment, emergency services, and outpatient services ( surgery, lab, X-ray, diagnostic tests, therapy and some injectable or infused drugs that cannot be self-administered.)
Medicare Advantage Plans (Part C) This plan is offered by Medicare approved private companies to those who qualify for Original Medicare. It is considered an “all in one” or “bundle plan.”

Also known as Part C, Medicare Advantage plans are required to provide the same benefits as Medicare Part A and B, but they may also cover additional benefits such as dental, vision, hearing, transportation, meals, wellness programs, and prescription drugs.

Medicare Part D (Prescription Drug Plans) Medicare Part D plans are prescription drug plans sold through private insurance companies. These plans are considered voluntary outpatient prescription drug coverage and approved by the federal government. They are designed for people primarily enrolled in Original Medicare (Part A and/or Part B). Two primary options are available:

  • Standalone: Purchased separately to supplement Original Medicare and some Medicare Advantage plans that do not include prescription drug coverage (PFFS or MSA).
  • Medicare Advantage with prescription drug coverage (MAPD): Part D is built into the Medicare Advantage plan.

While plans do vary in cost, deductibles, copays, and coinsurance, each plan must meet a standard level of coverage. All Medicare Part D plans have a formulary, which is a list of the medications covered under the plan. Many formulary lists use “tier levels:”

Medicare Supplement Plans (Part G) Commonly called Medigap plans, supplement plans help pay the remaining costs that Medicare doesn’t, such as coinsurance, copayments, and deductibles (excluding Part B deductible of $233 for 2022). A monthly premium does apply ranging from around $90 to several hundred dollars, depending on the private insurance carrier and zip code. Medicare supplement plans are only available with Original Medicare.
Medicare Advantage SNP Plans Special Needs Plans, or SNPs, are designed for people with specific conditions or characteristics by tailoring benefits, drug formularies, and provider choices to meet specific needs. Examples include plans designed for people with diabetes or other conditions, as well as plans tailored for people on state Medicaid programs. They may be offered as either HMO or PPO plans.
Medicare Advantage PPO Plans There are preferred networks of providers. Members have the option to choose out-of-network providers at a higher cost. No primary care physician or referrals for specialists are required, and prescription drug coverage is often available with this type of plan.
Medicare Advantage HMO Plans Typically requires staying in-network (except for emergency care) and requires having a primary care physician. Referrals are required for specialists, and prior authorizations may be required for certain treatments. In some cases, a point-of-service option is available that will provide flexibility with out-of-network services. This plan does have prescription drug coverage available.
Medicare Advantage PFFS Plans These plans generally allow members to receive services from any Medicare-approved provider and sometimes have a network of providers who have agreed to treat plan members. Members pay a higher cost if the provider does not agree to plan terms. No primary care physician or referral to specialists are required, and PFFS plans may include drug coverage or the member may purchase a standalone drug plan.
Medicare Advantage MSA Plans This is a high-deductible plan combined with a medical savings account (funded by Medicare). Members generally have no network or restrictions on which providers to use and can initially use their savings account to help pay for health care. They will have coverage through a high-deductible insurance plan once they reach their deductible. There is no drug coverage, so you can purchase a stand-alone PDP.

Important Medicare Dates

You may automatically be enrolled in Original Medicare when you turn 65 if you’re receiving Social Security, or after receiving disability benefits for 24 months. Otherwise, you must sign up during your Initial Enrollment Period, General Enrollment Period, or Special Enrollment Period:

  • Initial Enrollment Period (IEP): Most people get Medicare Part A (Hospital Insurance) and Part B (Medical Insurance). The enrollment period starts three months before you turn 65, includes the month of your birthday, and ends three months after you turn 65. If you’re not already collecting Social Security benefits before your Initial Enrollment Period starts, you’ll need to sign up for Medicare online or contact the SSA.
  • General Enrollment Period: If you miss your IEP, you can sign up during Medicare’s General Enrollment period that runs from January 1 to March 31, and your coverage will start July 1.
  • Special Enrollment Period (SEP): Once your IEP ends, you may have the chance to sign up for Medicare during a SEP. You can sign up for Part A and or Part B during an SEP if you have special circumstances.
  • Open Enrollment Period: This period runs from October 15 to December 7. If you have already enrolled in a Medicare plan, you can use this time to enroll and change prescription drug plans or Medicare Advantage plans.
  • Medicare Advantage Open Enrollment: This period runs from January 1 to March 15. If you’re enrolled in a Medicare Advantage Plan, this is when you can change to another type of Medicare Advantage Plan or disenroll and return to Original Medicare.

How to Compare Medicare Plans

Overall cost Consider the total out-of-pocket costs of any plan you are considering. Some will have a monthly premium in addition to your Part B premium, while others will not. Deductibles, copayments, coinsurance, and maximum yearly out-of-pocket expenses will also vary, so it’s crucial to look at the whole picture to ensure that you have the lowest overall costs and don’t get any surprises down the road.
Flexibility Some plans will allow you more choice in providers than others. Original Medicare and Medigap plans have no specific networks outside of accepting Medicare fee schedules. Medicare Advantage and prescription drug plans work differently. PPO and PFFS plans will allow you to go to any provider you choose, although possibly at a higher cost, while HMO plans will have strict network requirements and require referrals to specialists. Before choosing a plan, make sure that your doctor and pharmacy are in-network with the plan and that you understand the plan’s requirements.
Quality Every year, CMS publishes star ratings for every Medicare plan based on the plan’s overall quality and performance. Plans are rated from 1 to 5 stars, with 5 being the highest. Be sure to ask about a plan’s star rating before enrolling, and if a 5-star plan is available in your area, you may be entitled to a special enrollment period that allows you to switch to it. Another thing to consider are the company reviews, financial stability and standards of premium increase.
Coverage Plans will offer a wide variety of benefits and coverage models. Be sure that all of your medications are listed on the plan’s formulary and that you know what they will cost under the plan. If you are considering a Medicare Advantage plan, you should know whether the plan offers additional benefits like vision, dental, and hearing coverage and how you receive those benefits. Original Medicare will cover 80% of medically necessary charges. Members are subject to out of pocket costs such as deductibles, coinsurance, and copayments unless they elect adding a medicare supplement. Many medicare supplements will get the remaining 20%, as well as, coinsurance, copayments and some deductibles. When considering a medicare supplement the plan letter determines the amount of coverage.

How to Enroll In Medicare

You may automatically be enrolled in Original Medicare when you turn 65 if you’re receiving Social Security or U.S Railroad Retirement Board benefits (at least four months prior to start), after receiving disability benefits for 24 months, have ALS or ESRD. Otherwise, you must sign up during your Initial Enrollment Period, General Enrollment Period, or Special Enrollment Period.
