If the story of combatting the nation’s obesity epidemic were a movie, it would be Groundhog Day.
Year in and year out, for over a decade, advocates and obesity specialists worked to get changes in federal policy. They pressed to get bills passed in Congress, drafted white papers, published research findings in medical journals, held roundtables and briefings, and sent letters and emails to policymakers over and over. But, using the Groundhog Day metaphor, the same day would start again.
Until now. Just as the protagonist in Groundhog Day changed his way of thinking and got the girl, the Centers for Medicare & Medicaid Services (CMS) changed its thinking to recognize obesity as a distinct and serious chronic disease requiring treatment. Based on this reinterpretation, CMS published a potentially game-changing proposed rule to establish the treatment of obesity as a medically necessary service under Medicare and Medicaid and allow Part D coverage of FDA-approved anti-obesity medications (AOMs), including new injectable drugs called GLP-1s (glucagon-like peptide-1 receptor agonists), as a result.
However, better obesity care is not a movie, and the proposed rule, while a major development, is not a final action. Before Medicare and Medicaid beneficiaries can get treated with new anti-obesity medicines, the agency must go through a formal rulemaking process to finalize the proposed rule, including receiving and analyzing comments from individuals and organizations concerned about obesity. This process is now underway, and the obesity community is coming out in force to urge CMS to update its Medicare and Medicaid coverage policy for AOMs based on medical evidence that obesity medications treat the disease of obesity and are not merely agents for “weight loss.”
As the organization that partnered with the National Council on Aging (NCOA) and leading obesity specialists across the country to develop and issue the first Obesity Bill of Rights for the nation, NCL submitted comments as the voice of the nation’s consumers and urged CMS to finalize the proposed rules for these reasons:
There Is a Widespread Scientific Consensus That Obesity Is a Distinct Chronic Disease – CMS’s reinterpretation of Medicare Part D policy is grounded in extensive medical evidence that obesity is not a cosmetic condition but a distinct and serious chronic disease requiring treatment. Reinforcing this recognition of obesity as a distinct disease state, major medical organizations now consider obesity a chronic disease due to its complex biological mechanisms and potential for significant health complications. This includes the American Medical Association, American Association of Clinical Endocrinologists, American College of Endocrinology, and all the leading obesity and nutrition organizations.
Obesity Is the Nation’s Most Prevalent Chronic Disease and Is Directly Linked to Numerous Chronic Diseases –Today, obesity affects 41.9 percent of US adults – more than 100 million people – which makes obesity the most prevalent chronic disease affecting Americans, significantly eclipsing the other most prevalent chronic diseases: heart disease, diabetes, chronic kidney disease, cancer, chronic lung disease, Alzheimer’s Disease, and stroke. Even more significantly, more than 230 medical conditions are directly linked to overweight and obesity, meaning these diseases worsen as the degree of obesity increases. Thus, obesity today is responsible for an estimated 400,000 deaths a year.
The Cost of Obesity Is Too High and Everyone Is Paying the Price – Obesity, due to its role in causing or worsening chronic disease, accounted for 47.1 percent of the total direct and indirect costs of treating chronic conditions in 2016. Accordingly, some estimates put the national cost of obesity at $1.7 trillion a year –more than what Social Security paid in retirement benefits in 2022.
Compared to Other Serious Chronic Diseases, Obesity Goes Largely Undiagnosed and Untreated – The Obesity Bill of Rights was issued to transform obesity care in the US at a time when obesity remains largely undertreated with costly repercussions in high rates of obesity-related diseases and preventable deaths. Reflecting this reality, only 30 million of the more than 100 million Americans living with obesity in 2022 received a diagnosis of obesity, and only around 2 percent of those eligible for anti-obesity medications were prescribed these drugs. Although multiple factors are responsible for this pervasive gap in obesity care, the most pernicious are access barriers that keep people with obesity from getting the care they need, whether through the exclusion of obesity treatments in many insurance plans, restrictive insurance practices that delay or deny treatment, or out-of-date government policies.
New Anti-obesity Medications Are Safe and Effective and Result in Savings From Improved Health Outcomes – As noted in the CMS proposed rule, there have been major advances in understanding and treatment of the disease of obesity since the Medicare Part D program went into effect in 2006, resulting in new therapeutic agents, such as GLP-1 drugs that can help people lose up to 20 percent of their weight in 26 months. Calculating the potential savings resulting from better health outcomes when obesity is treated, studies are beginning to project the potential savings to the economy from covering obesity medications. One recent study published December 5, 2024, in JAMA Network Open estimated that a 10 percent weight loss resulting from obesity treatment saved $2,430 in reduced medical expenditures, and for a 25 percent weight loss, the reduction in health expenditures is $5,444 per person.
The comment period for the CMS proposed rule closes soon, and then it will be up to the new Trump Administration to finalize this important rulemaking. It is our hope that the new team at CMS will make this a priority. Simply put, this important change in CMS policy will make a significant difference in the lives of millions of Americans.
