Final answer:
Medicaid proportionally pays for a significant part of nursing home care, especially for the elderly below the poverty line. With an aging population and escalating healthcare costs, Medicaid's expenditures in this area are increasing, primarily due to price increases by health providers.
Step-by-step explanation:
The proportion of nursing home care that is paid by Medicaid is increasing due to a combination of factors. Firstly, Medicaid pays approximately two-thirds of the costs of nursing home care in the United States. This program is primarily designed to provide health care to those who are below the poverty line, including families with children, the elderly, and the disabled. With an aging population and increase in life expectancy, there is a growing number of elderly people requiring nursing home care. Medicaid has been facing increasing costs due to this demographic shift, in addition to price increases by health providers.
As healthcare costs rise and the population of elderly individuals increases, state governments have been financially burdened, leading to reconsideration and cuts in optional medical services. Given that Medicaid spending for the elderly, particularly for nursing home care, has increased, the correct answer is option D) is increasing due to price increases by health providers.
