In short

Plans must cover emergency care, even out of network.
Most surprise bills at in-network places are blocked too.
Ask for the written reason. If rules were broken, call 1-800-985-3059.

What this means

Out-of-network means the doctor or hospital is not in your plan's list. Two federal rules limit these denials. First, for an emergency, the plan must cover your care. It cannot ask for prior approval, even out of network [1]. Second, the No Surprises Act protects most people with private insurance from some surprise bills. These cover emergency rooms, some care at in-network hospitals and surgery centers, and air ambulance. Ground ambulance is usually not covered by this law. Your state may have its own rules [2].

If a job-based plan denies the claim, its notice must give the specific reason and refer to the plan provisions it relied on [3]. You can ask for your claim documents free of charge [5]. If you think the plan or provider broke the surprise-billing rules, you can send a complaint to the No Surprises Help Desk [4].

For a job-based plan, you have at least 180 days after the denial notice to appeal [6]. 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 [7]. After that, you have at least four months to ask for an outside review [8]. The sources here do not say whether your own bill falls under these rules. "Don't know yet" for your case.

Your next step

Write down the date and place of the care and the date on the denial notice. Ask the plan in writing for the specific reason, the plan provisions it relied on, and your claim documents. Say in your appeal what kind of care it was. The sources give at least 180 days to appeal for a job-based plan.
