Adequate health insurance after reaching the age of 65 is available at reasonable rates under the Medicare program to everyone who qualifies for Social Security benefits. Coverage was increased in 2006, but many elders nonetheless choose to carry supplemental health insurance to fill in the gaps (hence the name Medigap insurance). However, Medicare excludes coverage for skilled nursing facilities except up to 100 days arising from hospitalization after 90 days away from hospital or nursing home. Funding for long-term care may come from the patient, long-term care insurance, or Medicaid benefits when the patient qualifies. In 1998, a randomly selected 65-year-old was said to have a 45% chance of requiring long-term care, the average length of stay being 6 years. [cite?] Obviously, in some circumstances, such as chronic illness or family susceptibility, a future need for long-term care becomes a probability verging to a certainty.
