Summary: Original Medicare is federal government program designed to help US citizens with healthcare costs as they age. When covered through Medicare you pay all deductibles, premiums, and copayments, and may experience gaps in your coverage depending on the length of care or stay at certain facilities. For most medical services you’ll be responsible for 20% of the total cost and there is no yearly maximum, or cap, on the amount you can spend out-of-pocket. In addition, Original Medicare does not include prescription drug coverage or additional benefits for vision, dental or health and wellness.
