Medicare Drug Plan
by Cynthia M. Johnson, MA
About Medicare Prescription Drug Coverage
Medicare's prescription drug coverage (also called Part D) is a program to help people on Medicare pay for medicine. You can add Part D to Original Medicare. It can also be added to certain other Medicare plans. You can also get prescription drug coverage by enrolling in a Medicare Advantage Plan that offers it.
Most people who are 65 years and older or are disabled can enroll in Medicare. This includes Medicare drug plans.
When to Enroll
You can enroll in Medicare 3 months before your 65th birthday or 3 months after. People who are disabled can enroll during a 7 month window around their 25th month of disability. Medicare also has an open enrollment period from October 15 through December 7.
What it Covers
Private health insurance companies manage the drug plans for Medicare. They provide a list of brand name and generic drugs that they cover. The list can change over time. It is common for drug plans to exclude more expensive brand name medications when a generic one can be found. However, if there is a medicine that you really need, your doctor may be able to appeal and get it covered.
What it Costs
The costs depends on many things, such as the medicines you use, the plan, and whether you go to a pharmacy in your plan’s network. Here are some costs you can expect to pay:
