My spouse has health insurance through their employer. The premiums are paid post-tax. Is this eligible for reimbursement from the RMBA plan if I am a retired participant?

Yes. As long as you, your spouse, or your dependent is required to pay the premium in order to obtain coverage under your spouse’s group health insurance plan, and your spouse cannot pay the premium through his or her employer’s Section 125 Cafeteria Plan, the premium expense could be reimbursed through the plan.
