Home » Resources » Understanding Medicare Coverage for Genetic Testing

Welcome to our comprehensive guide on Medicare coverage for genetic testing. We strive to provide you with accurate and up-to-date information regarding healthcare coverage. In this article, we will delve into the details of Medicare’s coverage policies for genetic testing and offer valuable insights to help you understand the options available to you.

What is Genetic Testing?

Genetic testing is a medical procedure that examines an individual’s genes, chromosomes, or proteins to identify changes or variations that may be associated with inherited disorders or diseases. This advanced form of testing has the potential to provide valuable insights into an individual’s risk factors and guide personalized treatment plans.

Medicare Part A and Genetic Testing

Medicare Part A, also known as hospital insurance, primarily covers inpatient hospital stays, skilled nursing facility care, and some home healthcare services. When it comes to genetic testing, Medicare Part A generally does not provide coverage for standalone genetic tests. However, if genetic testing is conducted during an inpatient stay or as part of a covered procedure, Medicare Part A may cover the testing costs.

Medicare Part B and Genetic Testing

Medicare Part B, which covers outpatient medical services and preventive care, plays a significant role in genetic testing coverage. It provides coverage for medically necessary genetic testing services under specific circumstances. It’s important to note that not all genetic tests are covered by Medicare, and coverage is contingent upon meeting specific criteria.

Covered Genetic Testing Services under Medicare Part B

  • Hereditary Cancer Syndromes: Medicare covers genetic testing for hereditary cancer syndromes when certain criteria are met. This includes testing for breast, ovarian, colorectal, or uterine cancer susceptibility genes (such as BRCA1, BRCA2, Lynch syndrome genes, etc.) for individuals with a personal or family history of these cancers.
  • Pharmacogenomics Testing: Medicare may cover pharmacogenomics testing, which examines how an individual’s genes affect their response to specific medications. This type of testing helps healthcare providers determine the most effective and safe medications for patients based on their genetic makeup.
  • Diagnostic Genetic Testing: Medicare Part B covers diagnostic genetic testing for individuals suspected of having a genetic condition, provided that the test is ordered by a healthcare professional who accepts Medicare assignment. Diagnostic genetic tests help identify genetic mutations or abnormalities associated with specific disorders or diseases.
  • Screening for Sexually Transmitted Infections (STIs): Medicare covers certain genetic tests for sexually transmitted infections (STIs), such as Human Immunodeficiency Virus (HIV) and Human Papillomavirus (HPV), when deemed medically necessary.
  • Noninvasive Prenatal Testing (NIPT): Medicare covers noninvasive prenatal testing for pregnant women with certain risk factors or medical conditions that may impact the health of the mother or the fetus. This testing screens for chromosomal abnormalities, such as Down syndrome.

Medicare Advantage Plans and Genetic Testing

Medicare Advantage Plans, or Part C plans, are offered by private insurance companies approved by Medicare. These plans provide all the benefits of Original Medicare (Part A and Part B) and often offer additional coverage options, including genetic testing. Coverage for genetic testing under Medicare Advantage Plans may vary depending on the specific plan and its network of providers. It’s essential to review the plan’s documentation or contact the insurer directly to understand the coverage options and requirements.


  • Medicare Part A generally does not cover standalone genetic testing but may cover testing conducted during inpatient stays or covered procedures.
  • Medicare Part B covers specific genetic testing services, including hereditary cancer syndromes, pharmacogenomics testing, diagnostic genetic testing, screening for STIs, and noninvasive prenatal testing.
  • Coverage for genetic testing may also be available through Medicare Advantage Plans, which are offered by private insurance companies approved by Medicare.
