Medicare Adult Day Care Amendments of 1989

Medicare Adult Day Care Amendments of 1989 - Amends part B (Supplementary Medical Insurance) of title XVIII (Medicare) of the Social Security Act to provide for the establishment of adult day care programs providing certain health services to chronically-impaired adults in a group setting outside their homes for up to 125 days on a less than 24-hour basis. Requires providers of such services to have a multidisciplinary group of health care personnel conduct a written assessment of the status of each chronically-impaired adult before the adult's admission to the program and thereafter periodically develop and coordinate an individualized treatment plan for, and with the cooperation of, the adult.

Defines a "chronically-impaired adult" as an individual 18 years of age or older who has a physical, emotional, or mental impairment which, but for the provision of adult day care, would require the provision of care in a hospital, skilled nursing, or intermediate care facility.

Makes deductibles inapplicable to adult day care, requiring only the payment of a specified coinsurance amount.

Directs the Secretary of Health and Human Services to issue regulations regarding adult day care programs.
