In short

Federal law blocks most surprise bills you did not choose.
Ask your plan and the provider to review the bill under the No Surprises Act.
If the rules were not followed, call 1-800-985-3059.

What this means

A surprise bill is an out-of-network bill you did not plan for. In most cases the No Surprises Act protects you in three kinds of cases [1]. These are emergency room visits, some care at in-network hospitals and surgery centers, and air ambulance [1]. Ground ambulance is usually not covered by this law. Your state may have its own rules [1]. If you think someone broke the rules, you can send a complaint to the No Surprises Help Desk [2].

If your job-based plan denied the claim, you can ask for your claim documents free of charge [3]. You have at least 180 days after the denial notice to appeal [4]. The plan must decide within 72 hours for urgent care, 30 days for care you have not yet received, and 60 days for care you already received [5].

After that, you have at least four months to ask for an outside review [6]. HealthCare.gov says there is no charge if your insurer uses the federal external review process. Otherwise the charge can't be more than $25 per review [7]. The sources here do not say whether your bill is covered by the Act. "Don't know yet" for your case.

Your next step

If you think someone broke the rules, send a complaint to the No Surprises Help Desk [2]. If your job-based plan denied the claim, ask for your claim documents, which must be free of charge [3]. The deadline these sources give is at least 180 days after the denial notice to appeal [4].
