Before enrolling in Medicare, Diabetes patients typically ask one important question: "Are diabetic supplies covered by Medicare?" If you are diabetic, pre-diabetic or have a family history of diabetes, the answer to this question is of the utmost importance. Not only will your coverage dictate your out of pocket expenses, but it will determine whether you need additional medical coverage.The Diabetic Supplies Covered by MedicareFortunately, Medicare covers a wide range of diabetic supplies. According to Medicare.gov, the official government website, Medicare covers lancets, lancet devices, blood glucose monitors, testing strips, diabetes management training and other blood sugar control devices. In certain cases, therapeutic shoes may also be covered. For these supplies to be covered by Medicare, patients must obtain a prescription. Only the specific devices and supplies prescribed by a physician will be covered by your Medicare plan. On covered supplies, Medicare recipients will be responsible for paying 20% of the cost of their supplies after paying their Part B deductible.In addition to these supplies, Medicare covers bi-annual fasting blood glucose tests. However, to qualify for these tests, you must have been diagnosed with diabetes, high blood pressure, hyperglycemia or abnormal cholesterol levels. People who are at least 65 years of age, overweight, have a history of gestational diabetes or have a family history of diabetes might also qualify.What Medicare Does Not CoverWhile Medicare covers a wide range of diabetic supplies, it does not typically cover insulin, oral diabetes medications, insulin inhalation devices, syringes and other supplies needed to administer insulin. The only insulin covered by Part B is insulin administered using an external pump.If you want insulin, syringes, and other related supplies to be covered by your plan, you will need to enroll in Medicare Part D. Medicare Part D is the plan that covers the cost of prescription medication. Part D will also cover a portion of the cost of various anti-diabetic drugs. To keep healthcare affordable, insulin users might want to consider enrolling in Medicare Part D in addition to Part A and Part B.
