Participating in the Plan
You are eligible to participate in the Health Care Flexible Spending Account if you meet the eligibility requirements described in the Participating in Spending Accounts section.
If you participate in this plan, or are covered by another health care flexible spending account (e.g., through your spouse's employer), you are not eligible for the Marsh & McLennan Companies Health Savings Account.
You can enroll in this plan even if you are not enrolled in any Company medical plan.
My spouse contributes to a health savings account (HSA); can I participate in the Health Care Flexible Spending Account?
Under IRS rules, your spouse will not be eligible to contribute to a health savings account if you participate in the Health Care Flexible Spending Account.
