SAN ANTONIO — Weight loss treatments aren’t reaching many of the people who need them most due to coverage barriers, new data suggested.

Findings from three studies presented on November 5 at The Obesity Society’s Obesity Week 2024 meeting illustrate different aspects of the problem.

One, presented by Alissa S. Chen, MD, MPH, a postdoctoral fellow at Yale University, New Haven, Connecticut, found that people with obesity, particularly those with cardiovascular disease (CVD) and those who are Black and Hispanic, have high rates of cost-related prescription drug rationing. Those findings were simultaneously published as a research letter in JAMA Network Open.

“The implications are that structural barriers impede access to medications for Black and Hispanic adults with obesity, which might worsen if there’s not expanding coverage for GLP-1 RAs [glucagon-like peptide 1 receptor agonists], and it’s possible that broader insurance coverage could ameliorate some of these issues,” Chen said.

She noted that patients don’t always volunteer that information. “In my clinical practice, I always start by saying something like, ‘I have a lot of patients who can’t afford their medications. In the last week, was there a time [you didn’t take your medications due to cost]?’”

State Medicaid programs vary widely in the degree to which they cover weight loss treatments. But not a single one covers all modalities — nutrition counseling (NC), intensive behavioral therapy (IBT), obesity medications (OMs), and metabolic and bariatric surgery (MBS) — without restrictions or limitations, and only seven states cover them all with restrictions, according to a dual presentation by Christine Gallagher, MPAff, associate director for research and policy with the STOP Obesity Alliance at the George Washington University, Washington, DC, and Tracy Zvenyach, PhD, MS, RN, director of policy strategy and alliances at the Obesity Action Coalition, also in Washington, DC.

Detailed Medicaid coverage data for each state are posted on the STOP Obesity Alliance website. (As of now, Medicare doesn’t cover medications specifically for obesity at all.)

A third presentation, by Treah Haggerty, MD, of the Department of Family Medicine and director of the Pediatric Medical Weight Management program at West Virginia University, Morgantown, West Virginia, was of a qualitative descriptive study exploring the impact on 22 individuals enrolled in a medical weight loss management program whose state employee insurance carrier made a policy decision to stop covering all anti-OMs in March 2024. All had been prescribed GLP-1 agonists for weight loss, and the decision forced most to stop using them.

Those findings were published in the September 2024 issue of Obesity Pillars.

“Patients perceive the discontinuation of anti-obesity medication coverage as stigmatizing and unjust, leading to feelings of hopelessness and fear. With more insurance companies denying coverage for these costly medications, more information is needed to identify best ways to address the loss of coverage with patients. Clinical management of these patients should incorporate evidence-based obesity treatments while navigating insurance constraints,” Haggerty said.

Create a Safe Space to Discuss the Barriers

Asked to comment, Session Moderator John D. Clark, MD, PhD, chief population health officer at Sharp Rees-Stealy Medical Group, San Diego, California, told Medscape Medical News, “Health systems and payers are determining what can and can’t be covered, and at the end of the day, it frequently comes down to finances…I think the big challenge is really identifying patients who may have the greatest need…If we have limited resources, how and where should we be directing those resources? I would say the current system hasn’t really answered that question or identified patients for whom we would say that the cost truly is less than either the financial or long-term health benefits.”

But Clark said, “When some of these newer anti-obesity medications are able to go generic and be less expensive, which will happen eventually, I think things will change…and in the future, there will be more options on the market as well.”

In the meantime, he advised that clinicians “try to have conversations with patients about these barriers, acknowledge that these barriers exist, and create a safe space to discuss those barriers…Let’s see where we are right now, and let’s come up with a plan.”

People With Obesity More Susceptible to Drug Rationing

Chen reported on a sample of 51,720 adults who participated in the 2020-2022 National Health Interview Survey who did not have diabetes and who used at least one prescription medication of any type. Of those, 80% were White, 9.7% were Hispanic, and 9.7% were Black, and 33.9% overall had obesity.

Cost-related prescription rationing, defined as any self-reported skipping, taking less, or delaying filling a prescription to save money, was reported by 8.3% of those with obesity vs 5.9% without. After adjustment, rationing among those with obesity was significantly associated with younger age (aged 18-44 years), female sex, lower incomes, lack of health insurance coverage, and CVD.

The adjusted estimated probability of cost-related prescription drug rationing was 7.4% for those with CVD vs 4.4% for those without. By race/ethnicity, the proportions reporting rationing were 7.7%, 9.8%, and 10.7% for White, Black, and Hispanics, respectively.

“Given that few insurance providers cover GLP-1 RAs for obesity, cost-related prescription drug rationing could be exacerbated if patients were prescribed GLP-1 RAs at their current price of more than $1000 a month,” Chen noted, adding that the high prices could worsen health disparities among Black and Hispanic individuals with obesity.

Medicaid Coverage Lacking for All Obesity Treatments

For their project, Gallagher and Zvenyach delved into a database that aggregates Medicaid manuals, fee schedules, statutes, regulations, and preferred drug lists for each US state, both for Medicaid fee for service and top Medicaid managed care plans, in order to determine 2024 levels of coverage for NC, IBT, OMs, and MBS for adults with obesity.

No state provides coverage for all those treatments without either limitations — such as body mass index (BMI) cutoffs, age, or “comorbidity regardless of body mass index (BMI)” for OM and MBS — or outright restrictions, such as “proof of failed attempts.” And only seven states provide coverage for the four modalities “with limitations”: California, Arizona, New Mexico, South Carolina, Delaware, Rhode Island, and Massachusetts.

Twenty-two states don’t cover NC, although just one state doesn’t cover IBT. Overall, 37 states don’t cover OMs, and other states ranged considerably in various restrictions and limitations for OMs and MBS. Only four states fully covered the surgery without limitations or restrictions.

“The vast majority of states have significant barriers and conditions of coverage for obesity care,” Gallagher said.

Zvenyach added, “Most of the applied exclusions, limitations, or restrictions do not align with evidence-based practice standards or guidelines.”

When Coverage Stops, Hopelessness and Anger Emerge

Haggerty and colleagues’ research involved semi-structured interviews of the 22 participants — all of them women — who had lost their obesity medication coverage due to their insurers’ decision. Four themes emerged:

1. Feelings of hope replaced by hopelessness upon loss of medication coverage: One person said, “I’m afraid for my mental health. It’s tough to be in a situation where you’re never right. And it doesn’t matter what you do; it’s not going to work, and then to have just a glimmer of hope, a little spark of hey, look, this might help. And for someone else to take that away from you for no reason. I don’t know what am I supposed to do.”

2. Anger regarding the perceived injustice of anti-obesity medication coverage termination: For example, “They can pay for heart attacks, they could pay for me to have a stroke, they could pay for me to have diabetes, but they won’t let me have this one medicine that could take all of that away. Makes no sense.”

3. Perceptions of past and present stigma within the healthcare system and insurance company: “I’m not trying for vanity. I’m way too old to be a Victoria’s Secret model. I’m not trying to do it to be cute and skinny and hot. I just want to make it through a day of work and not be exhausted.”

4. Generational influences on obesity treatment: “I’m married, and my husband, since I’ve started this medicine, he’s been eating better. He’s been eating what I eat, and he’s been losing weight as well.”

Some participants said they planned to cope in different ways, including trying to obtain compounded versions of the drugs from “spas” or online pharmacies, as well as skipping doses, reducing doses, or sharing medications — in other words, rationing.

Asked by Medscape Medical News what clinicians should keep in mind, Haggerty said, “that there are big barriers and that we need to take care of the patients within this system that has their arm tied behind their back.
