What does Original Medicare cover?
Original Medicare will not cover hearing aids, fittings for hearing aids, or annual hearing exams. However, Medicare Part B can cover diagnostic hearing tests and balance exams as long as they are for a medical need, such as hearing loss because of an illness or injury.
You should make sure that your doctor accepts Medicare assignment. If your doctor does not and makes a request to have a hearing test, you may end up paying all of the costs. If your doctor does accept Medicare assignment, you will only need to pay 20% of the amount, along with your Part B deductible.
