How to get your employer to add GLP-1 coverage

TLDR. If your employer is self-insured, the benefit design is their decision, not the insurer’s. You can ask the employer to add GLP-1 coverage, expand it, or grant you an individual formulary exception. Most people never try. The ones who do succeed at a meaningful rate, especially at smaller employers. The ask works best when it comes with clinical context and an economic argument, not just a personal one.

Who controls the decision

At a self-insured employer, the benefit plan design is decided by the company. Not the insurer, not the plan administrator. The company. That decision is made by whoever controls the benefits budget: usually the CFO, VP of HR, or the benefits committee at larger firms.

Your HR contact processes claims and answers questions, but they almost certainly do not make formulary decisions. The person you want is the benefits director or VP of Total Rewards. At a company under 200 employees, it may be the CEO or CFO directly. Knowing who the decision-maker is matters before you spend political capital asking the wrong person.

The formulary exception request

A formulary exception asks the plan to cover a drug that is not on the standard formulary for a specific patient. This is different from asking the employer to add the benefit for everyone. It is narrower, cheaper for the employer, and easier to approve.

The request goes through the plan administrator (the insurer or third-party administrator processing claims). The employer does not need to change the plan design; they authorize the administrator to approve a one-off exception. Your prescriber initiates it with a letter documenting medical necessity, specifically why no formulary alternative is medically appropriate for you.

Formulary exceptions are reported to succeed roughly 30 to 50 percent of the time when the prescriber documents a genuine clinical reason. “I want the name-brand drug” is not a clinical reason. “Patient has tried and failed [alternative treatment X] and has a contraindication to Y” is. See the prior authorization letter guide for the documentation structure that works.

The benefit addition request

Asking the employer to add GLP-1 coverage as a plan benefit for all eligible members is a bigger ask. It changes the plan for everyone and increases the plan’s total claims exposure. But it is the right ask if you believe this affects more than just you.

These requests work best when framed around the employer’s interests, not just the patient’s needs. The economic argument is real: GLP-1s reduce the risk of cardiovascular events, reduce progression of type 2 diabetes, and improve worker productivity. Employers who exclude GLP-1s today may face higher cardiovascular and diabetes claims in five to ten years. The KFF and AHIP have published employer cost analyses on this point.

The practical steps:

1. Find allies. One employee asking for a benefit change is easy to ignore. Five or ten is a signal. Benefits teams track requests. Multiple requests from different employees, especially from high-performers or managers, get escalated.
2. Make the ask through the right channel. Most employers have a benefits feedback mechanism, either an annual survey, a benefits committee, or a direct ask process during open enrollment. Use it. A formal written request creates a paper trail; a verbal ask in the hallway does not.
3. Bring the clinical evidence. The SELECT trial (published in NEJM, 2023) showed that semaglutide reduced major adverse cardiovascular events by 20 percent in adults with obesity and established cardiovascular disease. That is the kind of evidence that moves a CFO. Your doctor can provide a letter summarizing it in the context of your case.
4. Address the cost directly. The employer knows GLP-1s are expensive. Acknowledging that and proposing a coverage structure that manages cost, a higher copay, a prior authorization requirement, a managed-care pathway, shows you understand their concern. An ask that ignores the cost objection is easier to decline.

Open enrollment: the natural window

Benefit design decisions are typically made two to four months before open enrollment. If your company’s open enrollment is in October or November, the decisions are being finalized in July through September. Requests made after decisions are locked accomplish nothing until the next cycle. Requests made before the planning window, or early in it, have a real chance of being incorporated.

Ask HR when the benefits planning process begins for next year. That gives you the target window for any formal request.

If the employer says no

A no on a benefit addition does not close every path. The formulary exception request remains open regardless of the plan-level decision. The formal ERISA appeal process, including external review, runs independently. And the cash-pay options are there as a bridge.

The lowest cash-pay floor today: compounded semaglutide from about $178/mo, Zepbound vials starting at $299/mo via LillyDirect. The GLP-1 cost guide maps every current option. If you have employer insurance that covers GLP-1s for diabetes but not obesity, and you have a diabetes or prediabetes diagnosis, your prescriber documents that indication on the prior authorization.

For the formal appeal process after a denial, the ERISA appeals guide covers internal and external review timelines and what documentation wins.

Frequently asked questions

Can my employer legally refuse to cover GLP-1s?

Yes. Federal law does not require employer health plans to cover GLP-1 medications for obesity. Employers have wide discretion in designing their benefit plans, especially self-insured plans governed by ERISA. Source: US Department of Labor.

What is a formulary exception and how do I request one?

A formulary exception asks the plan to cover a specific drug for a specific patient even if it is not on the standard drug list. Your prescriber initiates it with a letter documenting medical necessity. The request goes to the plan administrator, not your employer directly. Success rates are 30 to 50 percent when the clinical documentation is strong. See the prior authorization letter guide for what the letter should include.

Does the economic argument for GLP-1s actually help?

It helps more than a purely personal ask. Employers who cover GLP-1s cite reduced cardiovascular and diabetes risk as part of the decision, alongside talent retention. The SELECT trial evidence (semaglutide reduced major cardiovascular events by 20 percent) is the most cited data point in employer benefit discussions. Whether the argument is decisive depends on the employer’s cost situation and time horizon.

When is the best time to request a GLP-1 benefit addition?

Two to four months before open enrollment, when benefit design decisions are being finalized. For most employers with October or November open enrollment, that means requests in July through September have the highest chance of being incorporated. Requests made after the plan is locked wait until the next plan year.
