United States Hospitals have traditionally relied primarily on revenue

The passage explains that United States hospitals have traditionally relied on revenues from paying patients to offset losses from unreimbursed care. However, insurers have recently started limiting their payments to hospitals for insured patients, often capping the payments at or below the actual costs. Based on this information, let's evaluate the conclusions:

(A) Although the advance of technology has made expensive medical procedures available to the wealthy, such procedures are out of the reach of low-income patients.
This conclusion is not directly supported by the information provided. While the passage mentions the reliance on paying patients, it doesn't specifically address the availability or affordability of expensive medical procedures for low-income patients.

(B) If hospitals do not find ways of raising additional income for unreimbursed care, they must either deny some of that care or suffer losses if they give it.
This conclusion is directly supported by the passage. It states that hospitals rely on revenues from paying patients to offset losses from unreimbursed care. If hospitals cannot raise additional income, they will have to make choices such as denying some care or incurring losses if they provide it.

(C) Some patients have incomes too high for eligibility for government health insurance but are unable to afford private insurance for hospital care.
The passage doesn't provide information about patients' income levels or their eligibility for insurance. This conclusion goes beyond the scope of the passage and cannot be directly supported.

(D) If the hospitals reduce their costs in providing care, insurance companies will maintain the current level of reimbursement, thereby providing more funds for unreimbursed care.
The passage doesn't discuss the relationship between hospitals reducing costs and insurance companies increasing reimbursement. This conclusion introduces a speculative scenario that is not supported by the given information.

(E) Even though philanthropic donations have traditionally provided some support for the hospitals, such donations are at present declining.
The passage does not provide any information about the current state of philanthropic donations or their decline. This conclusion goes beyond the information given and cannot be directly supported.

Based on the analysis, the conclusion best supported by the information above is (B) – "If hospitals do not find ways of raising additional income for unreimbursed care, they must either deny some of that care or suffer losses if they give it." The passage indicates that hospitals rely on revenues from paying patients to offset losses from unreimbursed care, suggesting that without additional income, hospitals will face the choice of denying some care or incurring losses.
