How Much Does Medicare Pay for Thyroid Tests?

When your doctor performs your thyroid tests in outpatient settings, you’ll have 80% coverage under Part B. Therefore, you’ll be responsible for the Part B deductible as well as the 20% coinsurance.

Any thyroid tests given during a stay at the hospital would fall under Part A. You’ll be responsible for the Part A deductible and any other cost-sharing.

If you have a Medicare Supplement plan, any coinsurance will be covered by the plan. Depending on what letter plan you enrolled in, you may also have coverage for any deductibles. Leaving you with zero out-of-pocket costs.

How Often Will Medicare Cover Thyroid Testing?

In patients that are not at risk of hyperthyroidism or hypothyroidism, a test may be conducted up to two times per year. For patients who are at risk, if your doctor finds it medically necessary to test more than twice per year, Medicare may cover it.

Hypothyroidism is the result of a lack of production of thyroid hormones. Individuals with this condition may experience several signs or symptoms; while others may not have any.

Signs of hypothyroidism are dry skin, fatigue, feeling “foggy” or having poor concentration, slow reflexes, loss of hair, digestive issues (constipation), and weight gain. Other symptoms include feeling cold, fluid retention, aching muscles, and joints, slow speech, and depression. In some cases, women have had abnormally long cycles or excessive menstrual bleeding.


Although, not as common hyperthyroidism is the opposite. This condition is an overactive gland, excessively producing thyroid hormones.

In such cases, patients may have a higher metabolism. Signs may include tremors, nervousness, increased heart rate, anxiety, and excessive sweating. Individuals may notice a heat intolerance, more bowel movements than usual, unintentional weight loss, and even difficulty concentrating.

Many individuals with hyperthyroidism notice an enlargement of their thyroid gland. Those with hyperthyroidism will need a bone mass density test.

How to Get Help with Cost-Sharing for Thyroid Testing and Screenings Under Medicare

Many beneficiaries don’t know Part B does not cover 100% of your medical costs. You’re left with deductibles and coinsurance with zero caps on your maximum out of pocket costs. You can get most, if not all, your cost-sharing covered by enrolling in a Medicare Supplement plan. Medicare also does not cover any thyroid medications given at home. That’s where a stand-alone Part D plan comes into play.

  1. I had my thyroid ablated 27 years ago for Grave’s disease. My thyroid has been relatively stable over the years with thyroid supplements, but occasional changes in dosage have been needed. This year Medicare is denying payment on having my thyroid levels (tsh and free T4) checked. It has been a little over a year since they were last checked. Why would they deny this-claiming “frequency”?

    1. Hi Della! Medicare will cover thyroid testing two times per year. If you adjust the medications and need to test again to make sure the dosage is accurate, Medicare will also cover the test. Even if you already received two tests within the year. If Medicare denied the claim, I would talk to your doctor and submit an appeal. I hope this helps! If you have a policy through us, our Client Care Team can help you with the appeal!

  2. I am scheduled for ultrasound of thyroid next week at doctors clinic will I have to pay the 20%

    1. Hi Imogene! Yes, if you only have Part A and Part B without any supplemental coverage, you’ll be responsible for the 20% coinsurance as well as the Part B deductible of $198. If you have a Medigap plan, you’ll have coverage for the 20% coinsurance. Depending on the letter plan you enrolled in, you may also have coverage for the Part B deductible. I hope this helps!
