If your employer's health plan is self-funded, the decision about whether GLP-1s are covered sits with your employer, not with the insurance company whose name is on your card. Most covered workers are in that situation. In KFF's 2025 employer survey, 67% of covered workers, and 80% at firms with 200 or more workers, were in self-funded plans (KFF 2025 Employer Health Benefits Survey (external link)).
Why your employer has more control than you might think
A self-funded employer pays employees' healthcare claims directly instead of handing the risk to an insurer. The insurer or a third-party administrator runs the plan, but the employer decides whether GLP-1 medications are covered and under what conditions. That's a separate decision from the state and federal policy questions in our guides on state coverage mandates and Medicare coverage. State mandates, for example, don't reach self-funded plans at all.
Employers are split on the question, and size matters. KFF found that 43% of firms with 5,000 or more workers covered GLP-1s for weight loss in 2025, compared with 30% of firms with 1,000 to 4,999 workers and 16% of firms with 200 to 999.
How the decision gets made
- Benefits consultants and brokers usually model what adding GLP-1 coverage would cost against expected claims and present the employer with options: full coverage, coverage with strict prior authorization or BMI criteria, coverage for diabetes only, or exclusion.
- HR and finance leaders weigh that cost against the budget, against what peer companies in the same industry offer, and against employee demand.
- The decision is usually made once a year, ahead of open enrollment. So each year there's a window when it's open again.
How to make a credible case as an employee
- Ask before renewal season, typically several months before open enrollment, while benefits are still being modeled and not yet locked in.
- Use the right channel. That's usually HR or a benefits committee, not your manager. Some companies run a benefits survey or suggestion process for exactly this.
- Make a business case as well as a personal one. Employers respond to arguments about absenteeism, the healthcare costs of obesity-related conditions, and keeping their benefits competitive with peer employers.
- Organize with coworkers where you can. One request is easy to set aside. A documented pattern of interest from employees, through an internal survey, an ERG, or a benefits feedback channel, is harder to ignore.
- Bring outside data. Benefits consulting firms publish survey data you can point to. Mercer's 2025 national survey, for example, found that 49% of employers with 500 or more employees covered GLP-1s for weight loss, up from 44% in 2024 (Mercer, November 2025 (external link)). Figures like these help if your employer cares about staying competitive.
