Will Insurers Cover Wegovy and other GLP-1 drugs if Medicare Expands Access?
November 3, 2025

There is a general truth in the health insurance sector: If Medicare and Medicaid are given the green light to cover a certain drug, insurers in the group health and individual health insurance market usually follow suit.


The Centers for Medicare and Medicaid Services (CMS) typically allows Medicare drug plans and Medicaid to cover a drug once the Food and Drug Administration approves it for specific conditions. However, despite the FDA's approval of popular-yet-pricey GLP-1 drugs like Wegovy, Ozempic, and Zepbound for weight loss, these programs do not cover them due to a long-standing rule not to cover anti-obesity medications (AOMs)


In 2024, CMS issued a proposed rule that would cover AOMs used solely for weight loss.  However, in April 2025, CMS finalized the proposed rule but did not include coverage for AOMs solely for weight loss in the final rule.  CMS stated it would continue to review AOMs and may revisit coverage in the future.


If CMS finalizes the rule, will group health and individual health insurers follow suit? 


Current Medicare GLP-1 coverage


Medicare, through Part D drug plans, and Medicaid already cover GLP-1s for certain conditions, including:

  • Type 2 diabetes, and
  • Cardiovascular disease.
  • Currently, some states cover GLP-1 drugs and AOMs under Medicaid.


After the government programs began covering the medications for the above conditions, private insurers have largely done the same.


The drugs approved for these conditions include:

  • Ozempic
  • Mounjaro
  • Rybelsus
  • Wegovy

 

The fine print


Experts say that if CMS approves GLP-1s and other AOMs for weight loss, private health insurers would likely do the same. However, this does not mean they would cover them outright. Each plan's copays, deductibles, and coinsurance would still apply, as they do for all other drugs.


The list price of these drugs is around $1,000 a month or more, though some manufacturers offer savings programs that significantly reduce the cost to patients.. Since GLP-1s and AOMs are expensive specialty drugs, insurers would likely put them in their pharmaceutical fee schedule's most expensive tier, meaning that enrollees would pay higher copays and/or coinsurance than for lower-tier drugs.


Additionally, health plans that decide to cover these drugs may require plan enrollees to first try less expensive treatments and/or lifestyle changes before approving a GLP-1 prescription.

 

Effect on costs


The rising cost of specialty drugs are contributing to overall premium inflation.


In 2023, health insurance outlays for prescription drugs increased by 10.8%, compared to 2.6% for all medical expenses, according to the U.S. Department of Health and Human Services. This increase was driven by brand-name and specialty drugs, particularly those used to treat diabetes and weight loss, such as GLP-1 drugs. If more insurers start covering these popular drugs, it would likely affect premiums.


However, there could be offsetting cost benefits. Consider that:


  • These drugs often result in a significant drop in blood-sugar levels, reducing the risk of diabetes-related complications.
  • GLP-1s yield an average weight loss of 15 to 20%, and about one-third of users lose approximately 10% of their body weight, according to a study.
  • Multiple studies have shown that they can reduce the risk of cardiovascular events, including heart attack and stroke.
  • There is growing research to determine if GLP-1s address other health conditions besides diabetes and heart disease. 
  • The drugs may help people cut back on drinking, according to a study published in JAMA.


Conclusion

The future of Wegovy and other GLP-1 weight-loss drugs in Medicare coverage remains uncertain—but if CMS eventually expands access, private insurers will likely follow. Still, high costs, strict utilization rules, and placement in expensive drug tiers could shape how coverage is offered. For patients, this means progress toward broader access is possible, but planning ahead for out-of-pocket costs will remain essential. Staying informed—and working with a trusted advisor—can help you navigate these changes as the coverage landscape continues to evolve.

A Useful Way to Manage High Drug Costs Prescription medications can be one of the most expensive parts of healthcare for people on Medicare. For many beneficiaries, especially those taking specialty medications, the cost of prescriptions can quickly add up. In some cases, a single medication may cost hundreds or even thousands of dollars at the pharmacy. To help address this issue, Medicare introduced the Medicare Prescription Payment Plan , a program designed to make prescription drug costs more manageable by allowing beneficiaries to spread their out-of-pocket costs over time rather than paying them all at once. Unfortunately, many Medicare beneficiaries are not aware that this option exists. While this program is especially helpful for people who face high costs at the beginning of the year, it can also provide meaningful financial relief for those who are newly diagnosed with a serious condition and suddenly need expensive medications. You can learn more about the program directly from Medicare here: https://www.medicare.gov/prescription-payment-plan Why High Drug Costs Can Be Challenging Medicare Part D prescription drug plans often involve deductibles and cost-sharing that can create large upfront costs for medications. At the beginning of the year , these costs can feel especially burdensome because plan deductibles reset in January. Someone who fills a high-cost prescription early in the year may need to pay a large portion of the cost before their insurance begins covering more of the expense. But high costs don’t only occur in January. Many people experience significant prescription expenses when they receive a new diagnosis and start treatment for a condition such as cancer, autoimmune diseases, or other chronic illnesses. Specialty medications used to treat these conditions can be expensive, and the first prescription can create a financial shock for patients who were not expecting it. The Medicare Prescription Payment Plan helps by changing how those costs are paid , turning large one-time pharmacy bills into manageable monthly payments. How the Medicare Prescription Payment Plan Works The Medicare Prescription Payment Plan is available to anyone enrolled in a Medicare Part D prescription drug plan or a Medicare Advantage plan that includes drug coverage . Instead of paying your full out-of-pocket cost when you pick up a prescription at the pharmacy, the payment plan allows you to spread those costs out across monthly payments. Here’s how it works: Your Medicare drug plan pays the pharmacy for your prescription. Instead of paying the pharmacy directly, you receive a monthly bill from your drug plan . Your out-of-pocket prescription costs are divided into interest-free monthly payments over the remaining months of the calendar year. For example, if you fill an expensive prescription in February and enroll in the payment plan, your costs can be spread across the remaining months of the year instead of being paid all at once. It’s important to understand that this program does not reduce the total cost of your medications . Instead, it changes the timing of your payments so the cost is easier to manage. More details about how the program works are available here: https://www.medicare.gov/prescription-payment-plan Why This Program Helps at the Beginning of the Year Many people notice the biggest benefit of the program in January or February because that is when Medicare drug plan deductibles reset. Someone who takes a specialty medication may suddenly face a large pharmacy bill early in the year, before their plan begins covering more of the cost. By enrolling in the Medicare Prescription Payment Plan, that large upfront cost can be spread out across monthly payments, which can make a big difference for people living on fixed incomes. Why It Also Helps After a New Diagnosis The program can also be extremely helpful for people who are newly diagnosed with a serious illness . A new diagnosis often means starting treatment quickly, and the medications prescribed for conditions such as cancer, multiple sclerosis, rheumatoid arthritis, or other chronic diseases can be very expensive. Instead of paying a large pharmacy bill immediately after beginning treatment, the Medicare Prescription Payment Plan allows patients to break those costs into smaller monthly payments. This can help reduce financial stress during an already difficult time and may make it easier for patients to start treatment without delay. Who Is a Good Candidate for the Program? The Medicare Prescription Payment Plan may be particularly helpful for people who: Take high-cost specialty medications Expect to reach Medicare’s prescription drug spending limit during the year Prefer predictable monthly healthcare costs Have difficulty paying large pharmacy bills all at once Have been newly diagnosed with a condition requiring expensive medications On the other hand, people with relatively low prescription costs each month may not see much benefit from enrolling in the program. How to Enroll Enrollment in the Medicare Prescription Payment Plan is voluntary. If you have Medicare Part D coverage, you can contact your drug plan directly to ask about enrolling. The earlier you enroll in the year, the more months your payments can be spread across. However, you can typically enroll at any time during the year if you begin facing high prescription costs. Conclusion High prescription drug costs can create financial stress for many Medicare beneficiaries, particularly when expensive medications are needed unexpectedly. The Medicare Prescription Payment Plan offers a simple solution by allowing people to spread their prescription drug costs into interest-free monthly payments instead of paying the full amount at the pharmacy. Whether those costs appear at the beginning of the year or after a new diagnosis, this program can help make medications more financially manageable and provide greater predictability in healthcare expenses.
