Medicare Part D
Medicare Part D is a program that helps people with Medicare pay for prescription drugs. It is offered through private insurance plans that are approved by Medicare. You can choose a plan that fits your medications and your budget.
- What It Does:
Part D helps cover the cost of your prescription drugs. - How It Works:
You choose a plan from a private insurance company. Each plan has its own list of covered medications (called a formulary), so it’s important to check if your prescriptions are included and covered. - Costs:
Most plans have a monthly premium, a deductible, and cost-sharing like copays or coinsurance. Costs can vary from plan to plan. - Coverage Stages:
Drug coverage is divided into phases—starting with a deductible, followed by initial coverage, and then catastrophic coverage. Your out-of-pocket costs will change depending on which stage you’re in. - When to Enroll:
You can sign up for a Part D plan when you first become eligible for Medicare, during the Annual Election Period (October 15 – December 7), or during a Special Enrollment Period if you qualify. - Late Enrollment Penalty:
If you don’t sign up when you’re first eligible and you don’t have other creditable drug coverage; you may have to pay a penalty later. - Extra Help is Available:
If you have limited income and resources, you may qualify for Extra Help – a program that lowers your prescription drug costs. You can apply through the Social Security Administration.
