Cystic fibrosis is a genetic disease linked to changes in a gene located on chromosome 7. Chromosome 7 is the cystic fibrosis transmembrane conductance regulator or CFTR gene.

The CFTR protein is in the cell wall. This protein’s normal function is to regulate the transport of ions and chlorine within the cell wall.

In people with cystic fibrosis, the CFTR gene mutates so that the protein is either abnormal or absent. Chlorine can no longer flow normally through the cell wall. This lock of chorine flow creates an imbalance and increases fluid viscosity and local inflammation.

Today, more than 2,000 variants of the CFTR gene are known. Some are harmless, while others cause more or less severe diseases.

Medicare Coverage for Cystic Fibrosis

Medicare is the federal health insurance program. It provides healthcare for people 65 or older and under 65 with specific health conditions. Individuals on Social Security Disability insurance for two years can qualify for Medicare before age 65.

Medicare Part A covers treatment administered in an inpatient setting. Part A includes hospital and skilled nursing facilities.

Medicare Part B covers doctor office visits, outpatient medical services, durable medical equipment, diagnostic testing, and laboratory testing.

These two parts of Medicare are considered Original Medicare.

Medicare Part C is called the Medicare Advantage plan. These plans combine the benefits of Medicare Part A and Medicare Part B into one easy-to-use plan. In most cases, these plans also include your Medicare prescription drug coverage and additional benefits not covered by Medicare.

Medicare Part D is standalone Medicare prescription drug coverage. These Part D plans combine with Original Medicare and Medicare Supplement plans for drugs picked up from the pharmacy.

Private health insurance companies approved by the Centers for Medicare and Medicaid Services administer Medicare Part C and Part D plans.

Medicare Part B or Medicare prescription drug coverage administers the majority of the treatment for Cystic Fibrosis is covered under Medicare Part B or Medicare prescription drug coverage.

Medicare-Approved Treatment for Cystic Fibrosis

At present, there’s no cure for cystic fibrosis, and cystic fibrosis treatments help people manage their symptoms and live healthier lives. According to the Cystic Fibrosis Foundation, several treatment options exist, including medication, nutritional therapy, and fitness programs.

Airway clearance techniques

Airway clearance techniques can help people with cystic fibrosis clear their lungs to breathe more easily.

Inhaled medication

These types of medication can open a person’s airways and thin out mucus. Nebulizers, or aerosols, deliver liquid medicine as a fine mist.


Doctors can prescribe these to fight lung infections. The person can take medicine in several ways. Orally, intravenously, or via a nebulizer.

Dietary changes

A doctor may recommend that a person follow a high-calorie, high-fat diet to help maintain a moderate weight. They may also recommend supplements such as pancreatic enzymes, salts, or vitamins to increase nutrient absorption.

CFTR therapy

Cystic fibrosis transmembrane conductance regulator therapy is a new drug that targets the defective gene that causes cystic fibrosis. It then promotes the proper balance of salt and fluid in the lungs, thinning mucus.


Doctors may recommend a lung transplant to people with cystic fibrosis. However, the process involves an assessment and a lot of planning and preparation.

Some of the services covered by Medicare are listed below:

Testing and diagnosis

Although cystic fibrosis often occurs in childhood, this isn’t always true. Some people with cystic fibrosis don’t know they have the disease until adulthood. You’ll get the testing coverage you need under your Medicare Part B or Medicare Advantage plan.

Doctors and specialist visits

Medicare Part B or Medicare Advantage plans will cover doctor and specialist visits. If you use Medicare Part B, you don’t need a referral to see a specialist. Most Medicare Advantage plans require you to get a referral from your primary care physician before seeing a specialist.

Physical therapy

You can get physical therapy coverage through Part B or a Medicare Advantage plan. Medicare doesn’t limit the amount of physical therapy you can receive as long as your doctor believes the treatment is medically necessary.

Respiratory care

Respiratory care includes the services of a respiratory therapist. Medicare Part B or Medicare Advantage plans cover these respiratory services. However, suppose you receive respiratory care in a hospital, skilled nursing facility, or home health services. In that case, Medicare Part A will cover the services.

Pulmonary rehabilitation

Medicare Part B and Medicare Advantage plans cover outpatient care: outpatient pulmonary rehabilitation, not inpatient pulmonary rehabilitation. However, you may need prior authorization to use these services.

Lung transplant

Medicare will provide coverage if you need a lung transplant. Part B covers your doctor visits and preparation, and Part A will handle your transplant.

Medicare coverage for Cystic Fibrosis durable medical equipment

Medicare also covers the home medical equipment you need. Common devices include:

  • Home oxygen therapy, including oxygen tanks, plumbing, and other supplies
  • Atomizer
  • Chest physiotherapy waistcoat
  • Positive airway pressure machine
  • You must obtain your device from a provider who participates in Medicare.

Regarding Medicare costs for the treatments related to cystic fibrosis, what part of Medicare pays is key.

Suppose you need services such as a lung transplant under Medicare Part A. In that case, you can expect to pay the Medicare Part A deductible.

If you’re in the hospital for over 60 days, you can expect to pay an additional per-day copay. Likewise, when moved to a skilled nursing facility, you’ll be expected to pay a per-day copay after day 20.

For Services covered by Medicare Part B, such as diagnostic testing or physical therapy, you should expect to pay a 20% coinsurance and potentially a 15% excess charge, assuming you’ve met your Part B deductible.

Suppose you have enrolled in a Medicare Supplement to go along with your Original Medicare. In that case, you’ll pay much less out of pocket. These Medigap plans pick up all or part of your portion of the Medicare cost-share.

You’ll pay a fixed copay for most services on a Medicare Advantage plan. You may sometimes be responsible for 20%, but the coverage will stop charging once you reach your maximum out-of-pocket.

For prescription drugs purchased at the pharmacy, your costs will depend on what Part D prescription drug plan or Medicare Advantage plan you choose.

The plan you choose will dictate the charges you pay based on their fee schedule, found in the summary of benefits.
