As discussed by Brill, which of the following is NOT true of nonprofit hospital revenues? Group of answer choices Most nonprofit hospitals rely heavily on the tax-deductible charitable giving from members of the community to account for a large proportion of their revenue. According to a study mentioned by Brill, nonprofit hospitals have higher average operating profit margins than for-profit hospitals after taking into account the taxes paid by for-profit hospitals. Nonprofit hospitals have an average operating profit margin of 11.7%, even when including those nonprofit hospitals that lose money. Brill estimates that, if the cost of charity care were calculated based on Medicare rates, the nationwide value of this care would be less than $3 billion a year (or less than 1/2% of total revenue)
