Parts of Medicare

Medicare is the national health insurance program in the United States for those aged 65 and over.  It also covers those younger than 65 if they have been receiving disability benefits from Social Security for two years or have end stage renal disease or ALS (Lou Gehrig’s disease).

We help you understand the parts of MedicareMedicare consist of four parts: A,B,C and D.  Part A and Part B are collectively referred to as “Original Medicare”.

  1. Part A covers inpatient hospital services.
  2. Part B covers physician services.
  3. Part C,  or Medicare Advantage, is an optional all-in-one replacement of Original Medicare and is offered by private insurance companies.
  4. Part D is also optional and offers prescription drug coverage from a private insurance company.

Some basic insurance terms to know…

  • Deductible – the amount of money you pay before Medicare starts to pay its share
  • Coinsurance – the amount of the bill you’re responsible for after the deductible is paid, expressed as a percentage
  • Copay – a fixed amount of money paid to a provider before receiving service
  • Premium – the monthly amount of money paid to an insurance provider in exchange for insurance coverage

 Part A – Hospital Insurance

  • Inpatient – when you are formally admitted to a hospital floor under written orders from a doctor
  • Skilled Nursing Facility – a facility staffed by medical professionals that provides skilled nursing and rehabilitative services on a temporary basis
  • Benefit period – Medicare uses this to measure your use of a hospital or skilled nursing facility.  It begins the day you enter a hospital or skilled nursing facility as an inpatient and ends when you haven’t received received inpatient hospital or skilled nursing facility care for 60 days in a row.

In general, Part A’s coverage begins when you become an inpatient in a hospital or skilled nursing facility.  It pays your room and meal costs, along with the nursing and drugs you receive.  It also pays for hospice care, generally at your home, and home health care when you’re physically unable to leave your home.

Part A is free for the majority of people.  You pay no monthly premium for Part A if you, or your spouse, were employed for at least 10 years and paid the payroll tax for that period.  If you don’t qualify, you can still get Part A.  However, the premiums are steep, anywhere between $458 and $252 as of 2020.

Your Cost for Part A hospital insurance

Part A requires you to pay a deductible of $1,556 for each benefit period.  After this deductible is met, Part A fully covers your first 60 days in the hospital.  Days 61-90 require a daily coinsurance fee of $389.  This fee increases to $778 for days 91-150.  After day 150, you are responsible for 100% of the costs.  Note that the 60 days after day 90 are a considered your “lifetime reserve days”(you get up to 60 days over your lifetime).

Your cost for Part A skilled nursing facility care

Your first 20 days in a skilled nursing facility are covered fully by Part A.  If your stay in a skilled nursing facility extends beyond 20 days in a benefit period, you pay a $194.50 coinsurance fee per day up to day 100.  If your stay goes beyond day 100, then you’re responsible for all of the costs, as Part A doesn’t cover long term, or custodial, care.  Note that skilled nursing facility care is only available under Part A if you’ve spent a minimum of 3 days in a hospital for a related illness or injury.

Medicare Part A generally does not cover the services that surgeons, anesthesiologists, or other physicians provide in the hospital.  Part B is billed for these services.  Keep this in mind when  you’re sorting through your paper work following a hospital stay.

Part B – Medical Insurance

  • Outpatient – when you receive medical services without being admitted to a hospital or skilled nursing facility.
  • Observation status – a type of outpatient status;  when you stay overnight in a hospital in order for a doctor to properly diagnose your condition

Part B is the most commonly utilized part of Original Medicare.  It covers all outpatient care, doctor’s services, durable medical equipment (oxygen equipment, wheelchairs, walkers and hospital beds) and many preventive services.  It also covers emergency room visits when you aren’t admitted as an inpatient.

Unlike Part A, Part B has a monthly premium requirement. Part B will cost between $170.10 and $578.30 per month.  A vast majority of people will pay the $170.10 premium.  If you file an individual tax return and your income was below $91,000 two years ago, then you will pay the lower amount of $170.10.  The higher your adjusted gross income, the higher your monthly Part B premium.  The Part B premium will come directly out your Social Security benefit payment.

You may not need to enroll in Medicare Part B if you or your spouse is still working and have health coverage through an employer.  You will need to contact your employer’s benefit administrator to find out how your health coverage interacts with Medicare.  Go to Medicare Enrollment for more on Part B enrollment options.

Your cost for Part B medical insurance

Part B has an annual deductible of $233.  After your deductible is met each year, Medicare then pays 80% of all costs and you pay the remaining 20%.  There’s no yearly limit for what you pay out-of-pocket.

If you spend one or more nights in a hospital under observation status, your Part B will be billed for the services provided, not Part A.

Part C – Medicare Advantage

  • HMO – Health Maintenance Organization gives you access to certain medical providers within its network.
  • PPO – Preferred Provider Organization, like an HMO, features a network of doctors and hospitals, but there are fewer restrictions on seeing non-network providers.  Services provided inside the network will be offered at a discount to services provided outside of the network.
  • MOOP – maximum out of pocket expenses in a calendar year

Medicare Advantage is one of the parts of MedicarePart C, or Medicare Advantage, is an optional, all-in-one replacement, not a supplement, for Original Medicare.  It is offered by insurance companies, not the federal government.  The insurance companies are paid a set fee per enrollee by Medicare to provide the same services as Part A and Part B.  It may also cover services that Original Medicare doesn’t, like vision, hearing and dental.  It will often include a Part D drug plan.

You have to be enrolled in Original Medicare if you want a Medicare Advantage plan.  You also need to live in the plan’s service area and you need to continue to pay your Part B premium.

Medicare Advantage plans require you to use certain providers.  The plan contracts with doctors, hospitals and other healthcare providers in your area to form networks.  These networks are called HMOs or PPOs.

You will receive a medical card from your Medicare Advantage plan that you will use for medical services.  This card will replace your Original Medicare card.

Your Cost for a Medicare Advantage plan

Medicare Advantage plans can have monthly premiums as low as $0.  However,  you are exposed to a large maximum out-of-pocket expense (MOOP) if you need a lot of healthcare.  The MOOP is limited by law to $7,500 (in-network) or $11,300 (in-network and out-of-network combined).

Medicare Advantage plans have copays, coinsurance and sometimes deductibles.  All plans are different and are changed on a yearly basis, which means you’ll have to review your plan on an annual basis.  They are not standardized like Medicare Supplement, or Medigap, plans.

If you enroll in a Medicare Advantage plan you cannot also buy a Medigap policy.  Also, if you decide you don’t like your Medicare Advantage plan and want to switch back to Original Medicare supplemented with a Medigap policy, there are specific rules you must follow.  Additionally, in some instances, you may not be able to qualify for a Medigap policy based on your health.

Part D – Medicare Prescription Drug Coverage

  • Creditable prescription drug coverage – prescription drug coverage that is expected to pay on average as much as the standard Medicare prescription drug coverage (generally referring to your employer coverage)
  • Formulary – a list of drugs a Part D prescription drug plan covers

Part D is one of the parts of MedicarePart D plans offers insurance coverage for your prescription drugs.  It’s available to Medicare beneficiaries that are enrolled in Part A and Part B (note you do not have to be enrolled in Part C to get Part D).  Like Part C, the Part D prescription drug plan is optional and is offered by insurance companies, not the federal government.

You can get Part D prescription drug coverage in two ways:

  1. Part D prescription drug plans – These are “stand alone” plans and often referred to as “PDPs”.  Expect to pay a small monthly premium, a deductible, copays and coinsurance.  You have to live in the service area of the plan.  These plans are often paired with a Medicare Supplement plan to complete the coverage of Original Medicare.
  2. Medicare Advantage Plans – About 90% of Medicare Advantage Plans offer prescription drug coverage.  These plans are also referred to as MAPD (Medicare Advantage Part D) plans.  The monthly premium for the drug coverage is wrapped into the overall monthly premium.  Expect to pay a deductible, copays and coinsurance.  You have to live in the service area of the Medicare Advantage Plan – just like a stand alone Part D prescription drug plan.

Avoid the Part D late enrollment penalty!  How?  Simple…enroll during your Initial Enrollment Period.  Additionally, you can avoid the penalty as long as you have delayed enrollment because you have creditable prescription drug coverage.  However, once you lose your creditable coverage, you will have 63 days to enroll in Part D and avoid a penalty.  Your employer is required by law to send you an annual notice declaring if your coverage is considered creditable coverage.
