Insulin costs always seem to rise, which is a significant problem for many Medicare beneficiaries. These high prescription costs affect more than 3 million seniors. For many without this, medication isn’t an option. Failure to use it correctly can cause serious health concerns.

In January 2021, the Trump administration set forth an initiative called the Part D Senior Savings Model. The program was introduced to create lower costs and increase the affordability of insulin.

What is the Medicare Part D senior savings model?

The Part D Senior Savings Model was enacted to help limit the amount beneficiaries can pay for their insulin costs.

This model allows Medicare Part D prescription drug coverage to limit the expense of insulin to $35 throughout all coverage stages of the Medicare prescription drug plans. states that almost 27% of individuals over 65 have diabetes. This is why lowering the costs of insulin is so important.

Many Medicare beneficiaries have a hard time making ends meet. Some even face the challenge of paying for the medications they need to stay alive and their meals.

How the Part D senior savings model works

Because of the Part D Senior Savings Model, Medicare beneficiaries will have more choices regarding insulin. It’ll also limit the costs of a 30-day supply to no more than a $35 copay on select insulins. This cap is effective no matter what coverage phase the beneficiary is in.

Since this is a voluntary program, not all Part D plan sponsors or drug manufacturers participate. Several plan options will be available for the Part D Senior Savings Model.

The Centers for Medicare and Medicaid Services estimate that the average savings a Medicare beneficiary should experience is just under $500.

What Medicare plans participate in the Part D senior savings model?

The Part D Savings Model will apply to Medicare Advantage plans and standalone Part D coverage that participates. When enrolling in a participating program, you can expect to pay no more than $35 for your monthly supply of insulin.

Remember, every plan covers not all insulins, so ensure that your plans’ formulary insulins include the one you’re taking. Part D plans are standalone prescription drug coverage and have monthly premiums. These plans are usually combined with Original Medicare or a Medicare Supplement.

Medicare Part C

Medicare Advantage plans will combine your Medicare Part A and Part B. In most cases, your Part D benefits will also be included.

These programs are also called MAPD plans. Enrollment into an MAPD plan will have cost-sharing for your coverage dictated by the plan’s schedule of benefits, not the out-of-pocket costs outlined by Orignal Medicare.

If you’re taking a type of insulin from a drug manufacturer that isn’t covered, consult your healthcare provider to see if you can change to another insulin that’s participating. Part D sponsors can offer additional coverage gap discounts but often don’t.

They choose not to because it would lower the amount that the drug manufacturers are required to pay for beneficiaries in the Donut Hole.

Medicare Part D

Medicare PDPs consist of four coverage stages. Regardless of if you’re in your Deductible, Initial Coverage, or Coverage Gap stages. Suppose you’re taking a participating Insulin and enrolled in a participating plan.

In that case, you’ll pay no more than a $35 copay for one month’s supply of insulin. This results in more predictable costs for your insulin.

Without the model, if you were in the coverage gap phase, you’d be responsible for 25% of the cost of the insulin. In the catastrophic phase, you’ll pay 5% of the cost of a small copay, whichever is greater. The Medicare Part D Senior Savings Model now doesn’t affect the catastrophic phase.

Studies have initially shown that the average cost of Part D drug plan sponsors participating in the Senior Savings Model has higher premiums. In contrast, the average price of participating MAPD plans has decreased the monthly premiums.

Medicare Advantage plans vary depending on the area. Speak with a licensed insurance broker to find a Medicare Advantage plan that participates in the Part D Senior Savings Model.
