With most Medicare Part C plans, you can get slightly broader coverage than with basic Medicare Part A and Part B. For example, almost all Medicare Part C plans cover routine physical exams. Some offer short-term custodial care -- meaning nonmedical help with activities of daily life -- in a nursing facility or at home, which traditional Medicare doesn't cover. Also, some plans provide coverage for eye and hearing care, expanded physical therapy, chiropractic, and various kinds of preventive care.
