A MEWA is an arrangement that provides health or other welfare benefits to the employees of two or more unrelated employers. Association health plans, chamber-sponsored medical programs, and some professional employer organization health offerings can meet the definition and face dual federal and state regulation.
ERISA defines a MEWA broadly, and the key consequence is that state insurance regulators keep authority over these arrangements even though ERISA generally preempts state law for single-employer plans. Self-funded MEWAs may be subject to full state insurance licensing, reserve, and solvency requirements; fully insured MEWAs are subject to state rules on reserves and contribution adequacy. Federal requirements apply too, including annual Form M-1 filing with the Department of Labor and Form 5500 where applicable.
Employers are drawn to MEWAs for the promise of pooled purchasing power and rates that undercut the small group market. The history is uneven. Underfunded self-funded MEWAs have collapsed, leaving employers and employees with unpaid claims and no state guaranty fund backstop, and the Department of Labor has pursued numerous enforcement actions against fraudulent arrangements.
A health plan sponsored by a properly structured PEO may avoid MEWA status in some circumstances, and certain bona fide association health plans and collectively bargained arrangements are treated differently. If you are evaluating a multiple-employer arrangement, ask for the Form M-1 filing, state licensure documentation, stop-loss details, claims-paying history, and reserve levels, and confirm who is legally responsible if claims exceed funding. Verifying solvency before enrolling is far easier than pursuing unpaid claims afterward.
Because Congress carved them out. ERISA generally preempts state insurance law for single-employer plans, but it leaves state regulators authority over multiple employer welfare arrangements. Self-funded MEWAs can face full licensing, reserve, and solvency requirements, while fully insured MEWAs are subject to state rules on reserves and contribution adequacy.
Insolvency. Underfunded self-funded MEWAs have collapsed, leaving employers and employees with unpaid claims and no state guaranty fund to fall back on, and the Department of Labor has brought numerous enforcement actions against fraudulent arrangements. Pooled purchasing power is the promise; verifying that claims can actually be paid is the safeguard.
Documentation. Request the Form M-1 filing, state licensure records, stop-loss details, claims-paying history, and reserve levels, and get a clear answer in writing about who is legally responsible if claims exceed funding. Verifying solvency up front is far easier than chasing unpaid claims after the arrangement fails.
