Does Your Group Health Plan Cover GLP-1 Medications? Questions Washington Employers Should Ask

Why this belongs in your renewal review

SHRM’s 2026 Employee Benefits Survey found that 47% of surveyed employers covered GLP-1 medications for Type 2 diabetes management, while 15% covered them for weight management. The figures describe that national survey population; they do not establish coverage under a Washington employer’s plan. Source: SHRM’s 2026 findings

The difference shows why a broad yes-or-no answer can be misleading. Ask about the exact product and coverage criteria, not simply whether the carrier “covers GLP-1s.”

Start with the plan documents

Request the current prescription formulary, relevant benefit exclusions and clinical coverage criteria. Confirm that the information applies to the proposed plan and effective date. A drug list for a different product from the same carrier may not answer the question.

When reviewing a proposal, ask the carrier or administrator to answer these questions in writing:

• Which medications are on the formulary for this specific plan?
• Does coverage differ by the condition being treated?
• Is weight-management treatment included or excluded?
• Is prior authorization required, and who submits it?
• Are there step-therapy, quantity or pharmacy restrictions?
• What deductible, copay or coinsurance applies?
• How are existing authorizations handled when coverage changes?

These are questions to investigate, not a statement that every plan uses every restriction.

Explain coverage and approval separately

A medication appearing on a formulary does not, by itself, answer whether a particular claim will be paid. Where authorization is required, the carrier evaluates the request under the applicable criteria. The employee and prescribing clinician should work through that process.

Illustration: Two employees ask about medications in the same general category. One is asking about treatment for diabetes and the other about weight management. HR should not promise the same outcome for both. Each person needs a plan-specific answer through the carrier and their clinician, without discussing their medical circumstances in a group meeting.

A useful employee message is: “Coverage depends on your plan and the prescription details. Please contact the member-services number on your ID card and ask your prescriber whether authorization is needed.”

Compare the employee’s cost, not only the employer’s premium

Ask for a sample explanation of how a covered prescription would be paid before and after the deductible. Make clear that a sample is not a benefit determination for an individual employee.

Check whether the medication falls under a pharmacy or medical benefit and which pharmacy arrangements apply. Employees should also confirm any proposed manufacturer assistance directly with the program and their plan; do not treat a promotional price as the employee’s guaranteed ongoing cost.

For small groups, the available choices may be packaged carrier options. Avoid assuming a small employer can independently rewrite the drug benefit or choose a separate pharmacy arrangement. Ask which options are actually available to your group.

Communicate changes before employees discover them

If you select a new plan, give employees instructions for checking prescriptions and contacting the carrier before the effective date. Ask about transition procedures and required notices. Avoid promising that an existing authorization will transfer automatically.

Keep the conversation focused on access and plan administration. Employers can explain benefits without recommending a medication, determining medical necessity or collecting employees’ treatment histories.
