The emergence of GLP-1 drugs like Ozempic has revolutionized the treatment of Type 2 diabetes and obesity, offering unprecedented efficacy in weight management. However, their high cost has sparked a debate about insurance coverage, particularly within public healthcare programs like MassHealth. This article delves into the complexities surrounding MassHealth's coverage of GLP-1 drugs for weight loss, examining the factors driving costs, the restrictions being implemented, and the broader implications for public health and healthcare financing.
The Rise of GLP-1 Drugs and Their Impact
GLP-1 drugs initially gained approval for treating Type 2 diabetes in 2005, with their application expanding to weight loss in 2014. Newer versions boast enhanced potency and effectiveness, leading to a surge in popularity. In Massachusetts alone, the use of GLP-1 drugs among commercially insured individuals witnessed a significant increase, rising from 0.5% in 2018 to 3.2% in the first nine months of 2023, according to the Massachusetts Health Policy Commission. This translates to approximately 313,000 prescriptions for GLP-1 drugs written to commercially insured individuals in 2023.
While GLP-1 drugs are approved for both Type 2 diabetes and weight loss, the latter is experiencing the most rapid growth in prescriptions. Notably, the drugs specifically approved for weight loss tend to be more expensive. For instance, a month's supply of Wegovy, a popular weight loss drug, had an average commercial price of $1,303 in 2023, excluding rebates from the manufacturer.
The Financial Strain of GLP-1 Drugs
The escalating use of GLP-1 drugs has placed a significant financial burden on insurers. In Massachusetts, private insurers' total spending on GLP-1 drugs was projected to exceed $270 million in 2023, a substantial increase from $125 million in 2022. By 2022, these drugs already accounted for 5% of pharmacy spending among commercially insured individuals.
The potential for exceedingly high costs has prompted some insurers to limit coverage, resulting in considerable policy variations. Medicare Part D plans, which provide prescription drug coverage for seniors, are prohibited from covering weight loss drugs. MassHealth, on the other hand, began covering weight loss drugs when deemed medically necessary in January 2024, following negotiations for manufacturer rebates. However, starting in January 2025, MassHealth will require patients with obesity to first attempt an oral appetite suppressant before being considered for a GLP-1 drug. Private plans have also implemented various requirements, including prior authorization, enrollment in diet or exercise programs, the trial of less expensive drugs first, or proof of weight loss for continued coverage.

Some entities have taken more drastic measures, such as North Carolina's state employee health plan, which ceased covering GLP-1 drugs for weight loss due to the projected premium increase of $48.50 per subscriber per month. Blue Cross Blue Shield of Michigan also discontinued coverage for weight loss GLP-1 drugs, and the University of Texas stopped covering these injectables for its employees in 2023.
The Health Imperative of Addressing Obesity
The decision to limit or eliminate coverage for GLP-1 drugs raises concerns about addressing the significant health threat posed by obesity. According to the Centers for Disease Control and Prevention, nearly 42% of American adults were obese between 2017 and 2020. Obesity is a well-established risk factor for various health problems, including Type 2 diabetes, hypertension, and heart disease.
Medical experts like Dr. Hugh Taylor, president of the Massachusetts Medical Society, emphasize that preventative measures like diet and exercise are often insufficient for many individuals. He notes the remarkable effectiveness of GLP-1 drugs, stating that they are "in many cases as effective as surgery." The Massachusetts Medical Society and the national American Medical Association have advocated for greater insurance coverage for weight loss treatments, including GLP-1 medications.
However, there is currently a lack of sufficient research on whether the cost of GLP-1 drugs could be offset by the reduction in long-term health complications. This uncertainty makes it challenging to assess the true cost-effectiveness of these medications.
Innovative Approaches to Weight Management
To address the challenges of balancing access and cost, some innovative programs have emerged. Connecticut, for example, has partnered with Flyte for its state employee insurance plan. Flyte employs obesity specialists who provide virtual (and soon in-person) consultations to patients. These specialists develop personalized weight loss plans that often incorporate non-medication interventions and lower-cost medicines before resorting to GLP-1 drugs. Flyte also offers education and support to patients using these medications. Connecticut officials report that the program has demonstrated positive health outcomes while curbing the growth in prescriptions. However, some Connecticut doctors have voiced concerns about patients being referred to out-of-state virtual clinicians.

Addressing the High Cost of GLP-1 Drugs
Ultimately, a sustainable solution requires a reduction in the cost of GLP-1 drugs, which currently command prices in the United States that are four to five times higher than in other countries. According to KFF, Ozempic had a list price of $936 in the United States in August 2023, but less than $200 in countries such as Japan, Canada, Switzerland, and Germany, and less than $100 in the United Kingdom and Australia. While some argue that higher prices in the United States are justified by faster access to medicines and fewer restrictions, this disparity remains a significant concern.
Senator Bernie Sanders, chairman of the US Senate Committee on Health, Education, Labor, and Pensions, has been actively urging drug manufacturers to lower their prices. Research suggests that generic versions of these drugs could be manufactured at lower costs if legal, regulatory, and business obstacles are overcome.
Ron Mastrogiovanni, CEO of HealthView Services, emphasizes the critical role of the federal government in shaping drug prices, questioning whether it will be granted the authority to negotiate these prices.
