In short

Plans must cover true emergencies with no prior approval.
The test is what a normal person would think was an emergency.
Ask for the reason in writing, then use the appeal steps.

What this means

A plan can't use «not an emergency» to skip the rules. If a plan covers ER care, it must cover emergency services with no prior approval, even out of network [1]. The rule says what an emergency is. It is a condition with sudden, strong symptoms, including severe pain. A prudent layperson with average health knowledge would reasonably expect that waiting for care could put health in serious jeopardy [1]. HealthCare.gov says to go straight to the hospital in a true emergency. Insurers can't require prior approval for ER care at a hospital outside your network [2].

HealthCare.gov says these rights don't apply to plans created or bought before March 23, 2010 (grandfathered plans) [3]. The plan can tell you if yours is one.

Your next step

If the plan denied the ER claim, ask for the reason in writing, with the symptoms it used. Then follow the appeal steps in your denial notice. The sources do not say how the plan applies the rule to your visit. The sources give no deadline.
