Term	Definition
HEALTH INSURANCE PORTABILITY AND ACCOUNTABILITY ACT (HIPAA ) OF 1996:	A Federal law that allows persons to qualify immediately for comparable health insurance coverage when they change their employment relationships. Title II, Subtitle F, of HIPAA gives HHS the authority to mandate the use of standards for the electronic exchange of health care data; to specify what medical and administrative code sets should be used within those standards; to require the use of national identification systems for health care patients, providers, payers (or plans), and employers (or sponsors); and to specify the types of measures required to protect the security and privacy of personally identifiable health care information. Also known as the Kennedy-Kassebaum Bill, the Kassebaum-Kennedy Bill, K2, or Public Law 104-191.
HEALTH MAINTENANCE ORGANIZATION (HMO) (MEDICARE)	A type of Medicare Advantage Plan that is available in some areas of the country. Plans must cover all Medicare Part A and Part B health care. Some HMOs cover extra benefits, like extra days in the hospital. In most HMOs, you can only go to doctors, specialists, or hospitals on the plan’s list except in an emergency. Your costs may be lower than in the Original Medicare Plan.
HEMODIALYSIS (HD)	This treatment is usually done in a dialysis facility but can be done at home with the proper training and supplies. HD uses a special filter (called a dialyzer or artifical kidney) to clean your blood. The filter connects to a machine. During treatment, your blood flows through tubes into the filter to clean out wastes and extra fluids. Then the newly cleaned blood flows through another set of tubes and back into your body (See dialysis and peritoneal dialysis.).
HOME HEALTH CARE	Limited part-time or intermittent skilled nursing care and home health aide services, physical therapy, occupational therapy, speech-language pathology services, medical social services, durable medical equipment (such as wheelchairs, hospital beds, oxygen, and walkers), medical supplies, and other services.
HOSPICE CARE	A special way of caring for people who are terminally ill. Hospice care involves a team-oriented approach that addresses the medical, physical, social, emotional and spiritual needs of the patient. Hospice also provides support to the patient’s family or caregiver as well. Hospice care is covered under Medicare Part A (Hospital Insurance).
