"... according to a report from the Division of Health Care Finance and Policy, expanded coverage may have contributed to the rise in emergency room visits."
And since we know that The Bay State's experiment begat the ObamaTax, this should come as no surprise:
"Nationally, nearly half of ER doctors responding to a recent poll by the American College of Emergency Physicians said they've seen more visits since Jan. 1"
And 90% expect that number to rise in the very near future. Of course, that's to be expected: when you have "free" health insurance, a third party paying for the bulk of your care, and fewer doctors available to provide it, well, what did the rocket surgeons ion DC expect to happen?
