Annual Notice of Change (ANOC):

The Medicare Annual Notice of Change (ANOC) is a letter for people enrolled in Medicare Advantage plans and anyone with Medicare Part D prescription coverage. People with Medicare Advantage or original Medicare (Part A and/or Part B) can have Part D plans. The ANOC informs enrollees about any changes to their benefits for the coming coverage year. By law, Medicare Advantage and Part D plans must send the ANOC to enrollees by September 30 — which is before the annual Medicare open enrollment period of October 15 to December 7. Even if you have the same plan, your benefits could change year to year.

Premium:

A premium is the cost of having a health insurance plan and is usually paid monthly. Medicare enrollees may pay several premiums. Most people don’t pay anything for Part A hospital insurance, but some people do depending on how long they worked and paid taxes. For outpatient and preventive coverage, the Part B standard premium is $185 a month in 2025, but people with higher incomes pay more. Your premium for Medicare Advantage plans will vary, but even so-called “zero premium” plans require you to pay your Part B premium. Part D premiums range in price, but the average is about $47 a month in 2025. If you have original Medicare and a Medigap supplement plan, you have an additional premium for that coverage.

Deductible:

A deductible is the amount you pay out of pocket before your Medicare plan begins cost-sharing. In 2025, the Part A deductible is $1,676 per benefit period. The Part B deductible is $257 for the year, but you can access certain preventive care — including some vaccines — without meeting your deductible. Medicare Advantage deductibles vary and your Part D deductible can’t exceed $590 in 2025.

Out-of-pocket limit:

Original Medicare has no annual out-of-pocket maximum. Medicare Advantage plans have out-of-pocket limits. In 2025, they are $9,350 for in-network covered services and $14,000 for in-network and out-of-network covered services combined.

Medicare Prescription Payment Plan:

Starting January 1, 2025, anyone with Part D coverage had the option to use the Medicare Prescription Payment Plan for their out-of-pocket medication costs instead of paying upfront at the pharmacy. This plan doesn’t provide savings, but allows you to spread prescription costs — including your deductible — over the year. Making payments can be particularly helpful for people who may skip or delay picking up prescriptions because of high costs early in the year. Also in 2025, the Part D out-of-pocket limit dropped to $2,000.

Initial coverage phase:

After a Medicare enrollee meets the Part D deductible (if the plan has one), the health insurance begins cost sharing. The initial coverage phase means you pay coinsurance or a copay for covered prescriptions.

Catastrophic phase:

When you reach the $2,000 out-of-pocket maximum, your Part D plan pays for 100% of covered medications for the rest of the year.

How to save on drugs with Medicare

Medicare Part D is the part of Medicare that helps cover prescription medications, including both brand name and generic. It also includes coverage for certain vaccines that aren’t covered by Part B, as well as some medical supplies.

Even with Medicare Part D coverage, you may still have out-of-pocket costs such as premiums, deductibles, copayments, and coinsurance. As of 2025, Medicare Part D plans include a $2,000 annual out-of-pocket cap. Once you reach this limit, your plan covers the full cost of your covered medications for the rest of the year.

Still, there are several ways to reduce your prescription medication cost. From GoodRx coupons to patient assistance programs, here are ways you can save money on the medications you need.

1. See if you qualify for Medicare’s Extra Help program

The Medicare Extra Help/Low-Income Subsidy program is a federally funded program for people covered under a Medicare Part D plan. It helps reduce enrollees’ out-of-pocket costs by limiting their deductibles and copays. To qualify, your income and assets fall below a certain limit.

If you’re eligible, you may receive:

  • No monthly premiums for Medicare Part D

  • No Medicare Part D deductible

  • Low copays for prescription medications

2. Use GoodRx coupons

You can’t combine GoodRx coupons with Medicare, but you can choose to use a coupon instead of your insurance if it results in a lower price.

Here’s how to download a GoodRx coupon:

  1. Go to the GoodRx website, or download the GoodRx app on your phone.

  2. Search for your prescription medication.

  3. Enter your prescribed dose and quantity, then set your location.

  4. Compare prices across different pharmacies in your area.

  5. Click “Find the lowest prices” or press “Enter.”

  6. You can have the coupon sent by text or email, or print it out.

  7. To apply the discount, show the coupon at the pharmacy when you fill your prescription. Ideally, this is done at drop-off before the prescription is filled.

3. Consider the Medicare Prescription Payment Plan

The Medicare Prescription Payment Plan is a new program that can help make paying for medications more manageable. It’s open to anyone with a standalone Part D plan or those with Medicare Advantage plans that offer prescription medication coverage.

There is no cost to participate in the Medicare Prescription Payment Plan and participation is voluntary. Instead of paying for the total cost of your medications up front at the pharmacy, the payment plan allows you to spread the cost into smaller payments during the year. If you join, you will continue to pay your premium every month as well as an additional monthly amount on your payment plan. It’s a good idea to review how the Medicare Prescription Payment Plan works to determine if it’s right for you.

4. Compare Part D plans during open enrollment

Medicare open enrollment, which takes place every year from October 15 to December 7, is your chance to switch plans if another option offers better prescription medication coverage or lower costs. Plan costs and coverage details can change each year, so it’s important to review your options.

Here are some steps to help you compare plans:

  1. Make a list of all your medications and what dosages you take.

  2. Enter the names of your prescription medications to see which plans offer the best coverage.

  3. Look at premiums, deductibles, and medication costs for each plan. Plans usually change their formularies, premiums, and copays annually.

  4. Check if your preferred pharmacy is in each plan's network.

5. Get a 90-day supply

Opting for a 90-day supply instead of a monthly refill of your medication might help reduce your long-term out-of-pocket costs. Many insurance plans offer lower copays or bulk pricing for 3-month prescriptions.

If your medication is covered under your plan, see if your insurer’s mail-order or specialty pharmacy provides savings on a 90-day supply. If they do, ask your prescriber to write a prescription for a 90-day quantity to take advantage of these potential savings.

6. Ask about the generic version of your medication

Some medications have a generic version, and they generally cost less than the brand-name prescriptions. Generic medications are just as safe and effective as brand-name medications, so it’s an option worth considering to reduce your cost. Ask your prescriber about switching to a generic version of your medication to save money.

7. Consider lower-cost alternative medications

There may be other medications that help manage your condition, and they may cost less. If your medication is costly or not covered by your insurance, talk to your prescriber about lower-cost alternatives that might be a good option for you. Alternatives might have better insurance coverage or lower costs.

8. Learn more about patient assistance programs

Patient assistance programs (PAPs) offer free or low-cost medications to uninsured and low-income consumers. These programs, which primarily offer savings on brand-name medications, are usually run by private pharmaceutical companies or nonprofit organizations. You must meet certain qualifications and complete paperwork to receive savings from PAPs. However, some PAPs exclude Medicare recipients, so it’s important to review the program’s rules and requirements carefully.

9. Check state-funded resources

Depending on where you live, your state may offer programs to help you navigate prescription medication costs. A good place to start is your local Department of Aging. This U.S. Department of Health and Human Services office can help you find the best Medicare plan for the coverage you need.

Some states even have their own cost-saving programs for older adults. For example, Pennsylvania runs PACE and PACENET. These programs help eligible residents get prescription medications at reduced costs.

Alternatively, you can find out if your state has a State Pharmaceutical Assistance Program by using Medicare’s search tool. These programs are state-run and help qualifying residents pay for prescription medications.

10. Use a health savings account to pay for prescription medications

Although you can’t contribute to a health savings account (HSA) after enrolling in Medicare, you can still use any remaining funds in your account to pay for qualified medical expenses. An HSA allows you to use tax-free dollars to pay for eligible prescription medications. The money in your account does not expire so you can use your funds at any time to reduce your out-of-pocket medication costs.

Frequently asked questions about Semglee

Yes, Semglee is a long-acting insulin. You typically inject this insulin once daily. And it helps control your blood sugar levels throughout the day.

After you inject Semglee, it's absorbed slowly into the body and starts to lower blood sugar levels in about 2 to 4 hours.

The "-yfgn" in Semglee (insulin glargine-yfgn) doesn't stand for anything. It isn't an acronym, or shortened form of any words. But rather, it's a four-letter suffix added so that people don't confuse Semglee (insulin glargine-yfgn) with Lantus (insulin glargine), the first insulin glargine product on the market. Semglee (insulin glargine-yfgn) is a biosimilar to Lantus (insulin glargine). Being a biosimilar means Semglee is very similar to Lantus (insulin glargine) in terms of how well it works and what side effects it might cause. The FDA requires that all biosimilars have a four-letter suffix added to minimize confusion with the original medication and with other biosimilars.

Semglee and Lantus (insulin glargine) aren't exactly the same, but they're interchangeable biosimilar medications. This means that they're very similar to each other in terms of how well they work and what side effects they might cause. In addition, it means there's data that shows people can switch between the two medications without problems. You can think of Semglee as a generic of and possible lower-cost alternative to Lantus (insulin glargine). So if a healthcare professional (HCP) prescribes Lantus (insulin glargine) for you, your pharmacist can substitute it with Semglee without contacting your HCP for approval.

No, Semglee isn't the same as Ozempic (semaglutide). While both medications are prescribed to lower blood sugar levels, they work in different ways. Semglee is a man-made version of insulin, a hormone your body naturally makes to control blood sugar levels. Semglee is prescribed for people who don't make insulin or need more insulin than what their body can produce. Ozempic (semaglutide) is a glucagon-like peptide-1 (GLP-1) agonist. It's a lab-made form of GLP-1, another hormone your body naturally makes. GLP-1 plays different roles in the body, such as telling the body to release insulin or slowing down how quickly food moves out of the stomach. Ask your healthcare team if you have more questions about Semglee and Ozempic (semaglutide).

Some people have reported weight gain after starting insulins, including Semglee. The reason for this is because insulin tells your cells to take up sugar from the blood in order to lower blood sugar levels. The sugar in cells is then converted into fat. Over time, this can lead to weight gain. Talk with your diabetes care team if you're concerned about gaining weight while using Semglee. They can recommend ways to maintain a healthy weight by planning meals with lean proteins (e.g., turkey, fish), healthy fats (e.g, avocados, nuts), and fiber (e.g., leafy greens, broccoli). They can also help you build a regular exercise routine that's suitable for you. Talk with your healthcare team if you've more questions about the risk of weight gain from Semglee.

It's best to avoid drinking alcohol if you're using Semglee or any other form of insulin. Drinking alcohol raises your risk of low blood sugar levels, which is a serious side effect of insulin as well. But if you drink alcohol regularly and it's difficult for you to stop, let your diabetes care team know. They can recommend some resources to help you quit drinking or talk with you about what might be a safer amount to drink. It's important that you know how to recognize symptoms of dangerously low blood sugar levels, such as sweating, shakiness, and anxiety. Keep fast-acting sugars, such as glucose tablets, with you at all times so you can raise your blood sugar levels to a safe range.

If you just picked up Semglee pens or vials from the pharmacy and haven't started using them, you can store them in the refrigerator until the expiration date on the box, or at room temperature for 28 days. But once you've started using Semglee vials, you can store them at room temperature or in the refrigerator for up to 28 days. And if you've started using Semglee pens, they can be stored at room temperature for up to 28 days; don't refrigerate used pens again. Make sure to protect Semglee from heat and light.
