Does Medicare Cover Thyroid Tests?

  • Medicare with Melissa

Healthcare coverage, especially in the context of essential diagnostic services such as thyroid tests, can often be very confusing. For Medicare beneficiaries, it’s reassuring to know that Medicare does provide coverage for thyroid tests to diagnose and monitor a variety of thyroid-related conditions. These tests play a crucial role in monitoring thyroid health and assisting in early detection of thyroid disorders. Keep reading to discover how Medicare covers thyroid tests, the types of tests that are covered, and which medical conditions Medicare deems medically necessary.

Medicare Coverage for Thyroid Tests

Medicare Part B covers thyroid tests in outpatient settings, generously paying 80% of the costs. Just be aware you’ll still have to pay the Medicare Part B deductible and a 20% coinsurance fee. Conversely, if the tests are conducted during a hospital stay, then Medicare Part A would provide coverage. However, you’ll still be responsible for the Medicare Part A deductible and other out-of-pocket expenses.

It’s important to note that Medicare considers thyroid tests medically necessary when they’re ordered by a healthcare provider to diagnose or monitor a thyroid-related condition. Additionally, these tests must be performed at a Medicare-approved laboratory to qualify for coverage.

Medicare Supplement plans are also available to help pay your coinsurance fees. Depending on your specific Medicare Supplement plan, it could potentially extend coverage to cover deductibles, thereby reducing your out-of-pocket expenses substantially. For more information about Medicare Supplement plans, please give us a call at 866-MEDIGAP (866-633-4427).

How Often Does Medicare Cover Thyroid Tests?

For people not classified under high risk for thyroid conditions like hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), Medicare approves up to two tests yearly. In contrast, high-risk patients may, upon their physician’s recommendation and substantiated medical necessity, qualify for more frequent testing, courtesy of Medicare coverage. This policy underscores Medicare’s proactive stance in healthcare management, where regular check-ups preempt graver health issues.

Types of Tests Covered

Your healthcare provider can request various thyroid tests aimed at furnishing a comprehensive view of your thyroid health. Among the tests covered are assessments of thyroid-stimulating hormone levels (TSH), and evaluations of free and total thyroxine (fT-4 and T4), and Triiodothyronine (T3) levels. These evaluations offer deep insights enabling healthcare providers to:

  • Accurately gauge thyroid hormone levels
  • Scrutinize the efficacy of thyroid medications
  • Distinguish between primary or secondary hypothyroidism
  • Affirm or discard diagnoses of hypo or hyperthyroidism
  • Monitor the response to different therapeutic interventions

As you can see, these tests are very helpful and give physicians a thorough understanding of your thyroid health. That allows them to provide individualized, optimum care.

When are Thyroid Tests Medically Necessary?

There’s a variety of health conditions where tracking thyroid hormone levels becomes a critical step. This includes people suffering with metabolic disorders, a condition characterized by the body’s inability to efficiently convert food into energy. Likewise, malnourished individuals who suffer due to a deficiency in vital nutrients are also candidates for these tests. Assessing the ramifications of these conditions on thyroid functionality is integral to nurturing optimal health.

Furthermore, thyroid tests are vitally needed in situations of hyperlipidemia, identified by an elevated level of lipids or fats in the bloodstream. The tests are also pivotal in the presence of various forms of anemia, a condition which might indicate an underperforming thyroid, emphasizing the necessity for vigilant monitoring to facilitate timely intervention.

The field of mental health, encompassing a spectrum of psychotic and non-psychotic personality disorders, also mandates the need for thyroid testing. This is grounded in the fact that the thyroid gland modulates neurotransmitters directly associated with mental wellness and mood regulation. Consequently, any irregularities in thyroid hormone concentrations can considerably affect mental health states, positing thyroid tests as an essential tool in psychiatric care and fostering mental stability.

Thyroid tests hold a significant place in diagnosing and managing symptoms that are present in various bodily systems, being instrumental in determining underlying issues and aiding in tailored treatment planning. One area where these tests prove pivotal is in the cardiovascular system. People who experience various cardiac arrhythmias, characterized by irregular heart rhythms, often require thyroid tests to comprehend the root causes behind these issues, facilitating a targeted approach to their management.

The gastrointestinal system is another crucial area where thyroid tests come into play. People suffering from persistent issues such as chronic constipation or other digestive concerns might be advised to undergo thyroid evaluations. By doing so, healthcare providers can rule out or confirm any thyroid-related concerns. Doing so can offer a clearer path to alleviating these distressing symptoms and promoting a healthier digestive system.

The musculoskeletal system can sometimes exhibit signs pointing towards potential thyroid issues. For instance, symptoms like myalgias, which translate to muscle pains, can sometimes be indicators of underlying problems such as hypothyroidism. Undertaking thyroid tests in such scenarios helps in ascertaining if hypothyroidism is indeed a contributing factor, allowing for a more directed approach in treatment planning.


Medicare provides extensive coverage for thyroid tests if considered medically necessary and ordered by your healthcare provider. However, Medicare’s coverage for thyroid tests is subject to certain guidelines and requirements. Therefore, it’s important to familiarize yourself with your specific plan details and consult with your healthcare providers to ensure you receive the necessary thyroid tests without incurring any unexpected out-of-pocket expenses.

Meet Melissa MacCalla

Medicare is not simple and can be hard, frustrating, and downright confusing for most. I love when I get someone on the phone and I am given the opportunity to explain the difference in plans to them and have Medicare make sense. I enjoy talking to clients year after year, hearing about their families growing or them asking about mine.


Oh my gosh!! I was so confused about the Medicare Supplement process. I am turning 65 soon and am retired and have always had insurance thru my former employer. I didn’t know a thing about going on Medicare and was struggling to sort it all out.

A friend of mine recommended contacting Senior HealthCare Solutions, so I did. Melissa was FANTASTIC!! She was professional, responsive, caring and friendly. She explained the steps I needed to take, gathered my information, helped me choose good plans for MY specific needs and took care of my applications over the phone. 1-2-3, eesy-peesy and I was done!! And it didn’t cost me a DIME!!! WOW!!! I HIGHLY recommend Senior Healthcare Solutions for anyone who’s overwhelmed with making the right choices with Medicare Supplemental Insurance and Rx coverage. It’ll take a load off your mind!
