Impact of Medicaid Expansion on Hospital Volumes

From the press release:
—The Colorado Hospital Association (CHA) released a new study that shows hospitals in states that chose to expand Medicaid under the Affordable Care Act saw significantly more Medicaid patients and a related reduction in self-pay and charity care cases; whereas, hospitals in states that chose not to expand Medicaid experienced no changes outside normal variation in Medicaid volume or self-pay and charity care cases. The study, which is believed to be the first of its kind, used data from 465 hospitals in 30 states from the first quarter of 2014. Data was gathered from Jan. 1—the official launch of Medicaid expansion—to March 31. The increase in Medicaid volume (29 percent), which occurred only in expansion states, is demonstrably due to Medicaid expansion. However, the parallel decrease in self-pay (25 percent) and charity care (30 percent) shows that previously uninsured patients are the individuals newly enrolled in Medicaid.
