At least within the individual-market Marketplace, insurers are required to accept money orders and pre-paid debit cards. They do not have to accept credit card or debit card payments unless states make that a requirement, although many insurers currently accept all of these forms of payment. Therefore, it may vary from state to state and between insurers.
I don’t have a checking account. Can the insurance company require that I get one and pay my premiums through automatic monthly withdrawals?
No. Insurers offering coverage in the individual-market exchange or Marketplace are required to provide a variety of payment methods and cannot require a consumer to pay by automatic bank withdrawals (sometimes called electronic funds transfers, or EFT.) Federal rules require the insurer to accept paper checks, cashier’s checks, money orders, and all general-purpose pre-paid debit cards, as well as EFT. These methods must be available to consumers for both the initial premium payment (at enrollment) and ongoing payments.
