Part Two: What Medicare Part A Does Not Cover

Part A is often called hospital insurance, and most people qualify for it premium-free if they or their spouse worked and paid Medicare taxes for at least 10 years. But free does not mean unlimited.

Long-Term Custodial Care—The Biggest Gap in All of Medicare

This is the most consequential coverage gap in the entire Medicare program, and the one that surprises retirees the most. Medicare Part A will pay for skilled nursing facility care—but only under very specific conditions and only for a limited time.

Here is how it actually works: Medicare will cover skilled nursing care after a qualifying hospital stay of at least three days, but only for care that requires skilled medical professionals such as physical therapists or registered nurses. After 20 days, you begin paying a significant daily copayment. After 100 days, Medicare pays nothing.

Critical Gap: Custodial Care Is Not Covered: Medicare does NOT pay for custodial care — help with daily activities like bathing, dressing, eating, or using the bathroom. The average cost of a private room in a nursing home in the U.S. is more than $9,700 per month. Assisted living facilities, memory care units, and adult day care programs are also not covered by Medicare. This gap is the primary reason long-term care insurance exists.

Dental Care

Original Medicare does not cover routine dental care — no cleanings, no X-rays, no fillings, no crowns, no dentures, and no extractions unless they are medically necessary as part of a covered procedure. For retirees, who often face significant dental expenses as they age, this can mean thousands of dollars paid entirely out of pocket.

Vision Care

Medicare Part B covers a yearly eye exam for diabetic retinopathy and will pay for cataract surgery with corrective lenses afterward. But routine eye exams, eyeglasses, and contact lenses are not covered. For many seniors who develop presbyopia, cataracts, or age-related macular degeneration, vision costs can mount quickly.

Hearing Aids

Hearing loss affects roughly two-thirds of Americans over the age of 70, yet Medicare does not cover hearing aids or the exams to fit them. Hearing aids can cost anywhere from $1,000 to $7,000 per pair, and most people need to replace them every three to five years.
