Final answer:
The proportion of premium revenues spent on clinical services and quality improvements under the ACA is called the Medical Loss Ratio (MLR). The ACA's regulations aim to control healthcare costs and include a cap on administrative expenses and the adoption of electronic medical records.
Step-by-step explanation:
According to the ACA, the proportion of premium revenues spent on clinical services and quality improvements is called the Medical Loss Ratio (MLR). The Affordable Care Act, or ACA, introduced regulations designed to control the increases in healthcare costs. One method to enforce these regulations is the MLR, which requires health insurers to spend a minimum percentage of premium revenues on patient care and healthcare quality improvement, rather than on administrative costs.
The ACA also includes provisions such as a cap on the amount healthcare providers can spend on administrative costs and the mandate for healthcare providers to switch to electronic medical records (EMRs), reducing administrative expenses and possibly improving patient care coordination.
