Medicare and CF

What is Medicare?

Medicare, a federal health insurance program, is a coverage option for some people with cystic fibrosis, especially adults who are receiving Social Security Disability Insurance (SSDI) payments. If you are no longer able to work due to treatment burdens or other health-related issues, SSDI might be an option for you.

After two years of receiving SSDI benefits, you will be eligible for Medicare. Medicare Part A is premium free for most people who receive SSDI (sometimes called “premium-free Part A”).

In addition, Medicare could be an option for:

  • People 65 years and older who are receiving benefits from the Social Security Administration (SSA) or the Railroad Retirement Board (RRB)
  • People younger than 65 years who are receiving SSDI or people receiving certain disability benefits from the RRB
  • People with end-stage renal disease (ESRD), which is permanent kidney failure that requires dialysis or transplant

Medicare is broken down into four “parts” that help cover specific services:

  • Original Medicare Part A (Hospital Insurance)
  • Original Medicare Part B (Medical Insurance)
  • Medicare Part C (Medicare Advantage Plan)
  • Medicare Part D (Medicare Prescription Drug Plan)

Learning how each of these parts works and what services they cover can help you choose the right Medicare plan for you.

Medicare Part A (Hospital Insurance)

The first component of Original Medicare (Medicare Part A) focuses on inpatient care. Each type of Part A services comes with its own set of out-of-pocket expenses and may require you to pay various deductibles, coinsurance, and copayments. Services typically covered under Medicare Part A include: 

  • Inpatient hospital care
  • Skilled nursing facility care (not custodial or long-term care)
  • Hospice care
  • Home health care

Medicare Part B (Medical Insurance)

Medicare Part B, the next component of Original Medicare, focuses on medical services provided outside of hospitals and medical facilities. This includes doctor visits, outpatient services, some preventive care, and other medically necessary services. Medicare Part B typically covers:

  • Services from doctors and other health care providers
  • Outpatient care
  • Diagnostic tests (blood work) and imaging (X-rays, CT, PET scans, MRIs)
  • Home health care when homebound
  • Durable medical equipment
  • Some preventive services
  • Ambulance services
  • Emergency department services
  • Some prescription drugs (most nebulized CF medications are covered under Part B)

To receive Medicare Part B, you are required to pay a monthly insurance premium. Most people pay the standard premium amount ($148.50 per month in 2021), which is automatically deducted from your Social Security check each month. If you don’t sign up for Part B when first eligible, you may be subject to penalties. 

Out-of-pocket costs for Medicare Part B services vary. Generally, you will pay a deductible annually ($203 in 2021 and then 20 percent of the Medicare-approved amount for covered services, if you use providers who accept Medicare assignment. The Medicare Part B deductible and coinsurance do not apply to some screening and preventive services.

Medicare Advantage Plan (Part C)

Medicare Part C, also known as Medicare Advantage, is provided by Medicare-approved private insurance companies. The companies offering Advantage plans varies by geographical area (zip code and county). Medicare Advantage plans:

  • Include all benefits and services covered under Medicare Parts A and B
  • Cap Medicare Part A and B out-of-pocket costs in the calendar year
  • Usually include Medicare Part D -- or Medicare prescription drug coverage
  • May include additional benefits and services, such as dental, vision, hearing, and wellness programs

While Medicare Advantage Plans are required to follow Medicare guidelines, the amount paid for deductibles, copayments, and/or coinsurance varies by plan. These plans usually have network restrictions, limiting which doctors and hospitals you can use. These rules can change each year, and the Medicare Advantage plan must notify the enrollee about any changes before the start of the next enrollment year.

Medicare Part D (Medicare Prescription Drug Plan)

Medicare Part D, or the Medicare Prescription Drug Plan, is an optional benefit administered by Medicare-approved private insurance companies to help cover prescription drug costs. Those who wish to add standalone Part D coverage to Medicare Parts A or B are usually required to pay a monthly premium, which varies by the plan, household income, and the geographical area (zip code and state) of residence. Most Medicare Advantage Plans include Part D.

Medicare Extra Help

Medicare Extra Help is offered through the Social Security Administration to help people with limited income and resources with costs related to a Medicare prescription drug plan. Extra Help can lower drug copays and may help lower premiums and deductibles as well. You are automatically eligible for Medicare Extra Help if you:

  • Are eligible to receive both Medicare and Medicaid (referred to as full dual eligibility)
  • Have a Medicare Savings Program that assists with Medicare premiums and cost-sharing  
  • Receive need-based Supplemental Security Income (SSI) benefits but not Medicaid.

Medicare Supplemental Plans (Medigap)

Medigap is supplemental insurance to cover Original Medicare deductibles and coinsurance. Medigap plans are offered by Medicare-approved private insurance companies and have several requirements:

  • You must have Original Medicare Part A and Part B
  • You cannot have a Medicare Advantage and a Medigap plan at the same time
  • You must pay a separate premium for a Medigap plan, in addition to your monthly Part B and Part D premium
  • Medigap plans cover only one person. Your spouse must have a separate individual policy.

Because there is no annual enrollment period for these plans, you can drop your supplement at any time.

Medigap plans strictly follow Medicare guidelines, which means they will cover your Medicare costs for Medicare Part A- and B-covered services only. These plans pay after Medicare pays.

Some things to remember:

  • If you already have a Medicare Advantage Plan (Part C), you will not be able to purchase a Medigap plan unless you switch back to Original Medicare.
  • Medigap plans do not include prescription drug coverage, so you’ll want to purchase a stand-alone Part D drug plan to cover your medications.
  • Medigap plans are available in all 50 states, but in some states Medigap policies may not be available to individuals younger than 65. 

Medigap plans are standardizes and identified by letters A-N. Each plan follows the same structure for what costs it will cover. To get a quote for a Medigap plan, you must contact an insurance company offering the plan your area.

Medicare Eligibility and Enrollment

Knowing eligibility requirements and when you can enroll in Medicare will ensure you get the benefits you need when you need them.

Medicare is a federally funded health insurance option typically for individuals age 65 years or older. However, many people with certain disabilities or conditions, like cystic fibrosis, may qualify for the program without reaching the age requirement. Groups eligible for Medicare benefits include:

  • Individuals age 65 years or older
  • Individuals younger than 65 years who receive Social Security Disability Insurance (SSDI)
  • Individuals with end-stage renal (kidney) disease (ESRD)

Typically, people with CF qualify for Medicare through SSDI prior to turning 65. People younger than 65 who receive SSDI are automatically enrolled in Medicare Part A (hospital) and Part B (medical) and coverage begins 24 months after their SSDI eligibility. People with CF who have ESRD may be eligible for Medicare benefits sooner if they need dialysis or a kidney transplant.

Enrolling in Original Medicare (Parts A and B) and Part D

Enrollment periods for Original Medicare may depend on how you will receive benefits: through SSDI or by aging in at age 65 or older. You should enroll in Medicare Parts A, B, and D during your initial enrollment period to avoid financial penalties.

There are certain conditions under which eligible people may choose to delay enrollment in Parts B and D -- for example, if they are covered by an employer insurance plan based on active employment. However, Medicare must be notified of any choice to delay enrollment. Special enrollment periods allow individuals to sign up for Part B and D outside of initial enrollment due to life changes like loss of active employment insurance. 

Enrolling in Medicare Advantage Plans

When first eligible for Medicare Parts A and B, a person with CF may choose to enroll in a Medicare Advantage plan instead. Any changes to coverage -- for example, switching to a different Medicare Advantage plan or to Original Medicare -- may be made only during open enrollment periods. From October 15 to December 7th each year, you can join, switch, or drop a Medicare drug or Advantage plan. Plans selected during this time start the first of the next year. 

There is a special open enrollment period for those already enrolled in a Medicare Advantage plan that begins annually on Jan. 1 and continues through March 31. During this time, a person can switch to a different Medicare Advantage plan or go back to Original Medicare. They can only make a change once during this period. Coverage will begin the first day of the month after a person enrolls or makes changes to the plan. 

If you enrolled in a Medicare Advantage Plan during your Initial Enrollment Period, you can change to another Medicare Advantage Plan (with or without drug coverage) or go back to Original Medicare (with or without a drug plan) within the first 3 months you have Medicare.

Dual Eligibility

People who qualify for both Medicare and Medicaid are known as dual eligible. For Medicare-eligible individuals with limited incomes, dual eligibility allows for more comprehensive coverage and typically applies to those with significant medical needs.

What Services Are Covered?

Dual eligible individuals receive all benefits included in Medicare Part A, Part B, and Part D. In addition, Medicaid may also cover some medications and other benefits that Medicare does not cover, such as hearing, vision, dental, and transportation.

Coordinating Benefits With Medicaid

Medicaid does not pay first for services covered under Medicare. Medicaid covers only after Medicare, employer plans, or Medigap plans have been applied. It's important to make sure your benefits are coordinated when planning for medical services and treatments to ensure you get the most out of your benefits.
