In short
- Most plans must cover out-of-network air ambulance at in-network cost.
- The air ambulance company can't bill you for more than that share.
- Ground ambulance is usually not covered by this law.
What this means
CMS says the No Surprises Act protects you in most cases from unexpected out-of-network bills for air ambulance services [1].
Here is what the federal rule says. If a group plan or insurer covers air ambulance benefits, it must cover a nonparticipating air ambulance provider [2]. Your cost sharing must match what you would pay in network. It counts toward your in-network deductible and out-of-pocket maximum [2]. The rule figures the cost sharing as if the total charge were the lesser of two numbers: the qualifying payment amount or the billed amount [2].
The air ambulance provider must not bill you for more than your cost-sharing amount, or hold you liable for it [3]. The plan has 30 calendar days after the bill is sent to decide if it is covered. Then it must send an initial payment or a notice of denial [2]. These rules apply to plan years that begin on or after January 1, 2022 [3].
Limits: CMS says ground ambulance is generally not covered by these protections, unless a state law differs [1]. Short-term limited duration plans and health care sharing ministry plans are not covered either [1]. If you think the rules are not being followed, you can send a complaint to the No Surprises Help Desk at 1-800-985-3059 [4]. The sources here do not say what your own bill should be. "Don't know yet" for your case.
Your next step
Ask the plan for the EOB and the plan's decision on the air ambulance claim. Ask the air ambulance company for an itemized bill. Compare the amount they ask you to pay with your in-network cost sharing. If they still ask for more, call the No Surprises Help Desk. The sources give no deadline.
Check it yourself
Open the CMS rights page and compare your plan type with its list of exceptions. Your EOB and plan papers show your cost sharing - "Don't know yet" for your plan.
