Like most insurance plans, your Medicare Advantage plan will have a deductible. Your coverage will not begin until you have paid your deductible for the year. (Depending on the plan, the hearing aid benefit may or may not count toward your deductible; be sure to read the details of you plan so that you know what to expect.) After that, you may need to pay a copay or coinsurance when you get a hearing exam, hearing aid exam/fitting, or hearing aid(s).
