Gather your medical receipts and bills from the past year. Review them carefully. Determine if your current coverage was enough to keep your costs for medical care, services, and supplies within your budget. If you find that your out-of-pocket expenses were too high, you may want to consider other options during AEP. Have your healthcare needs changed over the past year? If you were recently diagnosed with a chronic illness or require new long-term medications, you will want to make sure that your current Medicare coverage will continue to meet your evolving needs.
