# [The surprise out-of-network bill: your No Surprises Act playbook](https://trymumm.com/guides/surprise-out-of-network-bill) > Compare the provider’s bill with your explanation of benefits and ask your insurer whether federal or state surprise-billing protections apply. CMS provides consumer help and a complaint process for possible violations. Keep the bill, plan details and any notices together. - **Updated:** 2026-07-20 - **Category:** Medical Bills - **Read time:** 8 min ## What the law actually bans The No Surprises Act provides protections for qualifying emergency services, certain non-emergency care at in-network facilities and air ambulances. Check your plan, care setting and any notice-and-consent documents against CMS’s consumer guidance. ## The three-check test Record the service date, facility, provider and insurance plan. Ask the insurer to explain the network status and how the claim was processed. Keep any notice-and-consent documents you signed and ask CMS or your state insurance department to help assess the applicable protections. ## Dispute in this order - The provider’s billing office: ask it to review the charge under the applicable surprise-billing protections and explain any amount beyond in-network cost sharing. - Your insurer: file an appeal demanding the claim be reprocessed as in-network under the NSA. Get the EOB corrected — your cost sharing derives from it. - CMS consumer help: submit a complaint through the No Surprises Help Desk for a possible billing-protection violation. The provider–insurer payment dispute process is separate from your consumer complaint. - Your state insurance department: ask which additional protections apply to your plan and care. ## The waiver trap Keep any notice-and-consent form and ask the provider to identify the service and charge it covers. Consent rules and exceptions depend on the care involved. Use CMS’s consumer guidance to assess the form rather than treating every signed admission document as a waiver. ## Questions people actually ask ## The ER doctor was out-of-network at an in-network ER — do I have to pay? Ask your insurer and provider to review the bill under the No Surprises Act and explain the patient responsibility. CMS provides consumer help for possible violations of applicable emergency-care protections. ## What if my plan is self-funded through my employer? The No Surprises Act includes qualifying coverage through self-funded employer plans. Ask the plan to explain which protections apply to your bill. Medicare and Medicaid use their own billing-protection rules. ## Can they send a surprise bill to collections while I dispute? Ask the provider and insurer to confirm in writing how your dispute affects billing and collection activity. Keep responding to notices and track their deadlines. Contact the CMS No Surprises Help Desk about a possible violation; filing a complaint is not a blanket pause on every collection process. ## What about ground ambulances? Federal No Surprises Act protections generally exclude ground ambulances. Check your state’s current protections and your policy, then request review of the itemized bill and remaining balance. ## Related - [How to negotiate a medical bill \(the actual playbook\)](https://trymumm.com/guides/how-to-negotiate-a-medical-bill) - [Medical bill in collections?
