Craig Hammer thought he was going to pay a few hundred bucks when he showed up to the Northwest ER in Westminster with a headache.

He left with some simple medical advice: Wait and see. It’ll likely go away on its own.

It did, and a few weeks later a different kind of headache arrived in the mail.

He now must pay $10,000.

There are now more than 20 freestanding emergency rooms in Colorado. Each one has signage that suggests it’s an emergency room.

But what does that mean? And what does that mean when it comes to cost?
