9. Uncovered Health Care

Even with Medicare, it’s no surprise that health care can be quite expensive in retirement. Yet many seniors don’t fully realize how much, in part because they think Medicare provides more coverage than it actually does, financial experts say.

The standard Medicare program comprises Part A, which provides hospital insurance, and Part B, which covers medical services like doctor visits. Many other services and expenses you may believe were routine—such as hearing, vision, and dental care, as well as prescription drugs and copays—are only covered by supplemental plans, which cost extra.

These medical services and expenses tend to be unforeseen during retirement, so you may want to be financially prepared to cover those hidden costs.
