Who's paying for ER visits

Medicaid pays for more emergency room visits than any other insurance program, according to recent data from the federal Agency for Healthcare Research and Quality. The health insurance program for the poor covered about one-third of all ER visits in 2014 — roughly 44 million of them , up from 26.5 million in 2006.

The big picture: Medicaid has been paying for more ER visits over time largely because the Affordable Care Act expanded the program. People in low-paying jobs that don't offer health benefits also rely on Medicaid coverage.
