You can sign up for a Medicare service during the initial enrolment period (IEP), which is seven months long. Original Medicare does not cover the majority of prescription drugs, so if you have Original Medicare, you will need to enrol in an independent drug plan. Always take into account the whole cost of the plan, including the deductible, cashback or coinsurance. From October 15 to December 7, each year, this is carried out. Use the search functions on Medicare and Medicare.gov to weigh the advantages and disadvantages.
