The Ultimate Guide to Original Medicare

Medicare Guide 2021

Medicare is a federal health insurance program offered by the Centers for Medicare and Medicaid Services (CMS). Medicare is comprehensive and flexible. This flexibility means that it is often confusing. Reading our ultimate guide below to understand Original Medicare in better detail.

What is Original Medicare?

Original Medicare is a fee-for-service healthcare plan offered by the government. Original Medicare consists of two main parts:

  • Medicare Part A: Hospital Coverage
  • Medicare Part B: Outpatient Coverage

Similar to most forms of health insurance, Original Medicare covers a large portion of health expenses, but still has out-of-pocket costs associated, such as deductibles and coinsurances. 

How Do I Qualify for Original Medicare?

There are multiple ways to qualify for Medicare. Some of the ways to qualify include:

  • Turning age 65
  • Collecting Social Security Disability for 24+ months
  • Diagnosis of ESRD or ALS

You must also be a US citizen or legal resident for at least 5 years.


How Much Does Original Medicare Cost?

Original Medicare consists of Medicare Part A and Medicare Part B, both of which have different costs associated.

Medicare Part A:

  • Premium- Most people do not pay a monthly premium for Medicare Part A. As long as you, or your spouse, worked 40 quarters (10 years), you will qualify for premium-free Medicare Part A. If you worked less than 40 quarters, your premium is dependent on the amount of quarters you worked. In 2021, if you worked 30-39 quarters, your monthly premium is $251. If you worked fewer than 30 quarters, your monthly premium is $471.
  • Deductible- The Medicare Part A deductible in 2021 is $1,484 per benefit period. This means that you may pay this deductible more than once in a year based on the length of time between hospitalizations.
  • Coinsurance- Medicare Part A has different coinsurances based on care. There is a daily hospital coinsurance past day 60, as well as a daily skilled nursing facility coinsurance past day 20.


Medicare Part B

  • Premium- Unlike Medicare Part A, Medicare Part B does carry a monthly premium for anyone enrolled. The standard Part B premium in 2021 is $148.50 per month. This premium, however, can increase based on your income. This premium income is known as IRMAA.
  • Deductible- Medicare Part B also has a deductible, but luckily this deductible is annual so you will only pay it once per year. In 2021, the Part B deductible is $203.
  • Coinsurance- Medicare Part B covers 80% of outpatient costs. This means that Medicare beneficiaries are responsible for 20% of all outpatient procedures. There are also other possible costs such as copayments and excess charges.

The “Original” in Original Medicare

When you hear people talk about Medicare, they’ll often talk about three things: Original Medicare, Medicare Advantage Plans, and Medicare Supplement Plans. It’s important to understand the different terminology. Original Medicare  is called “original” because it’s the basis for Medicare. There are two main parts to Original Medicare: Medicare Parts A and B. These are the parts of Medicare that most people are enrolled in. They cover inpatient/hospital care and outpatient services respectively. 

Medicare Supplement Plans and Medicare Advantage Plans are additional coverage options that Medicare beneficiaries can voluntarily enroll into.

Medicare Supplement Plans are private gap policies sold by different insurance companies to decrease out-of-pocket expenses of Original Medicare. These Medicare Supplement Plans, also called Medigap policies, can only be paired with Original Medicare.

Medicare Advantage Plans are completely different from Original Medicare. They are a private alternative to Original Medicare. These are plans offered by private insurers. They often add different bonuses, like dental insurance or prescription drug coverage.

It is important understand that when we are referring to Original Medicare, we are strictly speaking about Medicare Part A and Medicare Part B.


Applying for Original Medicare

There are two ways to enroll into Original Medicare. You are either enrolled automatically when you turn 65, or you apply for Original Medicare through Social Security.

If you are turning 65 and you are already drawing Social Security benefits or benefit from the Railroad Retirement Board, you will be automatically enrolled in both Medicare Part A and Part B. You will receive your Medicare card about 3-4 months prior to your 65th birthday. Although you are automatically enrolled, you can defer this enrollment if you have another form of creditable health insurance, such as an employer group plan through your spouse. Your Medicare enrollment letter will have directions on how to defer your enrollment. 

If you are not drawing Social Security or Railroad Retirement Benefits prior to 65, you will have to submit an application for Original Medicare. You can do this application up to 3 months before your 65th birthday. If you plan to continue working past 65, you can also defer your Medicare application as long as you have another form of creditable health insurance. To apply for Medicare, you will want to visit the Social Security website for an online application, which you can easily find using our link


Medicare Part A

Part A is one of the two parts of Original Medicare. In previous years, everyone was enrolled into this part of Medicare when turning 65 without an application. In recent years, however, the policy was updated and now senior must apply for Medicare Part A themselves. 

Part A Coverage:

Medicare Part A is considered your hospital coverage. You can think of this as your “room and board,” which includes:

  • Inpatient care
  • Skilled Nursing Facility
  • Hospice Care
  • Some Home Health Care


Part A Cost:

Most people have premium-free Medicare Part A. Essentially, Part A is free as long as you, or your spouse, have worked 40 quarters, which is the equivalent of 10 years. If you have not worked the minimum 40 quarters, your Medicare Part A will have a monthly premium. This premium is dependent on how many quarters you worked.

 Although most people will have a $0 premium with Medicare Part A, there are still other costs associated. One large cost is the Medicare Part A deductible. In 2021, the Part A deductible is $1,484 per benefit period. This deductible is NOT annual, and some beneficiaries may pay the deductible more than once per year if there is more than 60 days between hospitalizations.

Medicare Part A also has different coinsurance amounts dependant on service and length of service. For inpatient hospitalizations, your $1,484 deductible covers your for days 1-60. Past day 60, if you have only Original Medicare, you will begin paying a daily copayment. If you are still hospitalized past day 90, your daily copayment will increase. The coinsurance amounts are:

  • Days 61-90: $371 per day
  • Days 91-150 (60 lifetime reserve days): $742 per day

You will also have coinsurance for rehab stays if you are discharged from the hospital to a skilled nursing facility. The coinsurance amounts for skilled nursing facilities under Medicare Part A are:

  • Days 1-20: $0 per day
  • Days 21-100: $185.50 per day

Medicare Part B

The second part of Original Medicare is known as Medicare Part B. Unless you are drawing Social Security or Railroad Retirement Benefits prior to age 65, you must submit an application for Medicare Part B.

Part B Coverage:

Where Medicare Part A is your hospital coverage, Medicare Part B is considered your outpatient coverage. These outpatient services can occur both in and outside of the hospital. Part B is broken down into two categories:

  • Medically Necessary Services
  • Preventive Services


Medicare Part B Cost:

Unlike Medicare Part A, there is no premium-free Medicare Part B. Anyone who applies for Medicare Part B will have a monthly premium. In 2021, the standard premium for Part B is $148.50. This monthly premium, however, can increase based on your most recently available tax return. Social Security will assess your Modified Adjusted Gross Income (MAGI) typically from two years prior, and can increase your premium based on that amount. This premium increase is known as IRMAA.

Aside from the monthly premium, Medicare Part B also has an annual deductible, which in 2021 is $203. Luckily, unlike Medicare Part A, you will only pay this deductible once per calendar year.

As for coinsurance, Original Medicare covers 80% of Medicare Part B charges. This means that without any additional coverage, such as a Medigap plan, you are responsible for 20% of all Medicare Part B charges. There is no limit to this 20%.

It's important to understand the different parts of Medicare and what they cover. I'm hapy to help with any questions!

Role of Medicare Supplements

As you can imagine, out-of-pocket expenses can begin to add up very quickly with Original Medicare. Between the Part A deductible, and both the Part A and B coinsurance amounts, your bill can sky rocket pretty quickly. Without Original Medicare having an out-of-pocket maximum, costs to beneficiaries can become catastrophic.

Luckily, there are insurance plans designed to cover these costs and limit the amount of out-of-pocket expense you may encounter. Medicare Supplement Plans, also known as Medigap plans, are designed to fill the gaps left behind by Original Medicare. These plans have an affordable monthly premium, and very little out-of-pocket expense for all medical costs covered by Original Medicare.

For example, if you are schedule for an outpatient surgery with only Original Medicare, you will be responsible for the Part B deductible ($203) and 20% of all surgical costs. However, if you have a Medicare Supplement Plan like Plan G, your only out-of-pocket for an outpatient surgery is the Part B deductible of $203 (if you have not already met it that calendar year).

This is an optional addition to Original Medicare.
