Does insurance cover genetic testing?

Insurance often covers genetic testing when your clinician recommends it and the test is medically necessary, but each plan decides which tests it covers and many require prior authorization. Consumer DNA kits are generally not covered.

Medicare covers certain tests under set rules, mostly for people with cancer. Before you test, call your insurer with the test name and code your clinician plans to order and ask whether it is covered for your reason.

Medical necessity decides coverage

Health plans pay for genetic tests they consider medically necessary for you, and each insurer keeps its own list of covered tests and criteria. Tests that commonly meet that bar include:

  • Testing to diagnose a suspected genetic condition when you have symptoms.
  • Inherited cancer testing when your personal or family history meets the plan's criteria.
  • Tumor (biomarker) testing to choose cancer treatment; see biomarker testing.

Tests with little proven benefit are often excluded. For example, University of Utah Health Plans' 2025 policy calls MTHFR testing investigational and not medically necessary for all indications; see MTHFR test.

Prior authorization and how to check

Prior authorization is approval from your plan before you get a service. Without it, the plan may not pay. Many genetic tests need it. To check your coverage:

  1. Ask your clinician or genetic counselor for the exact test name, lab, procedure (CPT) codes and diagnosis codes.
  2. Call the number on your insurance card. Ask whether the test is covered for your diagnosis, whether prior authorization is needed, and whether the lab is in network.
  3. Ask what you'll owe after your deductible and coinsurance.
  4. If it is denied, ask for the reason in writing. Your clinician can send more information, and you can appeal.

Medicare and preventive coverage

  • Medicare, tumor testing: covers next-generation sequencing (NGS) of the tumor for people with advanced cancer (recurrent, relapsed, refractory, metastatic, or stage III or IV) who plan further treatment, when the test meets CMS criteria.
  • Medicare, inherited cancer testing: covers germline NGS for people with breast or ovarian cancer who have a clinical indication and risk factor, and local contractors may cover it for other cancers. Tests must be ordered by the treating physician and run in a certified lab.
  • Marketplace and most private plans: breast cancer genetic test counseling (BRCA) for women at higher risk is a preventive service with no copay in network. Coverage of the test itself and of other genetic tests varies by plan.

Medicaid coverage depends on your state's program. Ask your state Medicaid plan.

Will testing affect my insurance?

The federal Genetic Information Nondiscrimination Act (GINA) bars health insurers from using genetic information to decide eligibility or coverage, and bars employers with 15 or more workers from using it in hiring and promotion. GINA doesn't cover life, disability or long-term care insurance.

If your plan won't pay, ask the lab for a self-pay price; see genetic testing cost. Gabriel can help you compare health plans at no cost, and Gabriel membership is not health insurance.

Common questions

Will my insurance pay for genetic testing?

It may, if your clinician recommends it and it meets your plan's medical necessity criteria. Call your insurer with the test code before testing.

Does Medicare cover genetic testing?

Medicare covers certain tests, mainly tumor testing for advanced cancer and inherited cancer testing for people with certain cancers and risk factors. It must be ordered by your treating physician.

Do I need prior authorization for genetic testing?

Often, yes. Ask your insurer before the sample is taken, because the plan may not pay without approval.

Does insurance cover 23andMe or other consumer DNA tests?

Generally no. MedlinePlus notes some consumer tests may be reimbursable through an HSA or FSA; check with your plan administrator.

Can my health insurer raise my rates because of a genetic test?

GINA bars health insurers from using genetic information in eligibility and coverage decisions. Life, disability and long-term care insurers aren't covered by GINA.
