Medicare will usually cover the cost of hearing tests and exams however Medicare usually only covers around 80 percent of the cost of those hearing tests and exams to determine if you need hearing aids.
However Medicare does not cover the cost of the actual hearing aids though and you'll either have to pay out of pocket for the hearing aids or look into other health insurance to pay for hearing aids.
Medicaid will usually cover part of the cost for purchase of hearing aids if they are deemed medically necessary by your doctor.
But you still may have to cover part of the cost of the hearing aids yourself.
Most other health insurance such as private health insurance will cover the cost of hearing aids if they are deemed medically necessary.
So if you have private health insurance or Medicaid then that can help pay for hearing aids.
