In short

For emergencies, a plan has to cover out-of-network care.
The No Surprises Act guards most private plans from some surprise bills.
If you think the rules were broken, you can complain.

What this means

If your plan covers ER care, the federal rule says it has to cover emergency services. It can't ask for approval first, even out of network [1]. CMS says the No Surprises Act guards people with most private health plans from some surprise bills. That includes ER visits, and non-emergency care at an in-network hospital or surgery center [2]. Generally, ground ambulance services aren't covered by these protections, unless a state law has different rules [2].

If you think your plan or provider broke the rules, you can send a complaint to the CMS No Surprises Help Desk. They check whether the rules were followed [3].

Your next step

Send your question or complaint to the No Surprises Help Desk if you believe the rules aren't being followed [3]. The sources give no deadline.

Check it yourself

The CMS pages above list the rules and the Help Desk phone line.
