Comprehensive Coverage of Janumet by Medicare

Home » Resources » Comprehensive Coverage of Janumet by Medicare

Janumet is a prescription medication that combines two active ingredients, sitagliptin and metformin, to help control blood sugar levels in individuals with type 2 diabetes. Sitagliptin works by increasing the levels of incretin hormones in the body, which stimulate the release of insulin and reduce the production of glucose in the liver. Metformin, on the other hand, improves insulin sensitivity and reduces the amount of glucose produced by the liver. Together, these two components of Janumet provide an effective treatment option for managing diabetes.

Medicare Part D Coverage for Janumet

Medicare Part D is a prescription drug coverage program available to Medicare beneficiaries. It is important to note that Part D plans are offered by private insurance companies approved by Medicare. These plans vary in terms of the medications they cover, cost-sharing requirements, and formularies. Formularies are lists of covered medications, and they can differ from one plan to another.

Janumet is categorized as a brand-name medication, and its coverage under Medicare Part D will depend on the specific Part D plan you have chosen. It is essential to review the formulary of your plan to determine whether Janumet is included and, if so, under what coverage tier. The coverage tiers usually range from Tier 1 (preferred generic drugs with the lowest copayment) to Tier 5 (specialty drugs with the highest copayment).

Potential Out-of-Pocket Costs

While Medicare Part D provides coverage for prescription medications, it is important to consider the potential out-of-pocket costs associated with Janumet. These costs can include deductibles, copayments, and coinsurance.

Deductibles: Some Part D plans may require beneficiaries to meet an annual deductible before coverage begins. The deductible amount can vary among plans.

Copayments and Coinsurance: After the deductible is met, beneficiaries will typically be responsible for copayments or coinsurance for their medications. These costs can vary based on the specific Part D plan and the coverage tier assigned to Janumet.

It is crucial to review the details of your Part D plan to understand the specific cost-sharing requirements for Janumet. Additionally, discussing your options with a Medicare representative or a licensed insurance agent can provide further clarity on the potential out-of-pocket expenses.

Alternative Options for Coverage

If Janumet is not covered by your current Medicare Part D plan or the associated out-of-pocket costs are prohibitive, there may be alternative options available to help you access the medication at a more affordable price.

  • Medicare Advantage Prescription Drug (MAPD) Plans: These plans, also known as Medicare Part C, provide an all-in-one alternative to Original Medicare. Many MAPD plans include prescription drug coverage and may offer a more comprehensive formulary that covers Janumet.
  • State Pharmaceutical Assistance Programs (SPAPs): Some states offer SPAPs to assist individuals with high prescription drug costs. These programs are designed to provide financial assistance or subsidies to eligible individuals to help cover the cost of medications like Janumet.
  • Patient Assistance Programs (PAPs): Pharmaceutical manufacturers often have PAPs in place to help individuals who cannot afford their medications. These programs provide free or discounted medications, including Janumet, to eligible individuals who meet specific income requirements.

Exploring these alternative options can potentially help you find a more suitable and affordable coverage solution for Janumet.


In conclusion, Medicare’s coverage for Janumet varies depending on the Part D plan you have chosen. It is crucial to review the formulary of your plan to understand the coverage and potential out-of-pocket costs associated with this medication. If Janumet is not covered or the costs are high, alternative options such as MAPD plans, SPAPs, and PAPs may provide viable solutions.

Remember, understanding your specific coverage and exploring alternative options can help ensure that you have access to the medications you need while minimizing your out-of-pocket expenses.
