What Is a MEWA? The Structure Behind Every Association Plan
Multiple Employer Welfare Arrangements are how group buying legally happens — and why regulators watch them closely.
Any arrangement where two or more unrelated employers share one health plan is a Multiple Employer Welfare Arrangement — a MEWA. Every association health plan is one, which means every serious conversation about group buying eventually arrives at MEWA rules.
Why the scrutiny
MEWAs have a checkered history: undercapitalized arrangements in past decades collected premiums and collapsed mid-claim, leaving members with medical bills and no insurer. That history is why federal law makes MEWAs file annually with the Department of Labor and why states retain full authority to regulate them on top of ERISA.
Well-run MEWAs — fully insured, state-registered, backed by genuine associations — operate successfully today. The structure isn't the problem; capitalization and oversight are.
Why it matters here
Proposed AHP legislation would expand who can form these arrangements, but state MEWA oversight survives under every version — including in California, which regulates aggressively. Understanding MEWAs is understanding both the promise and the guardrails of group buying.
