It depends. Insurers are allowed to make changes to your health plan each year. For most people, their premium will change, and many will see changes to their benefits, cost-sharing, or provider networks. Your insurer should have sent you a notice explaining any significant changes to your plan premium or benefits. You should review that notice. However, even if you still want to keep your same plan, it is important that you return to the Marketplace, update your account information, and select a plan to ensure you receive the correct amount of financial help, if eligible.
