The No Surprises Act, effective January 1, 2022, protects most insured U.S. patients in group health plans from surprise medical bills by out-of-network providers for emergency services, air ambulance services, and non-emergency services at in-network facilities. Patients pay only in-network cost-sharing amounts. Disputes occur between providers and health plans through negotiation or the federal Independent Dispute Resolution (IDR) process--patients do not initiate IDR directly. This federal law from the U.S. Departments of Health and Human Services (HHS), Labor (DOL), Treasury, and Centers for Medicare & Medicaid Services (CMS) controls the issue; credit card chargebacks, merchant refunds, or general insurance claims do not apply.

Contact your health plan and provider first with your bill, explanation of benefits (EOB), and service details. Request negotiation between them. If unresolved, escalate via your plan or file a complaint with CMS/HHS.

What the No Surprises Act Controls

The No Surprises Act applies to most group health plans, including fully insured and self-insured plans. It shields patients from balance billing--where out-of-network providers charge beyond what the plan pays--in specific scenarios: emergency services from out-of-network providers, air ambulance services, and non-emergency services from out-of-network providers at in-network facilities. Patients are responsible only for in-network cost-sharing like copays or deductibles.

The dispute process starts with negotiation between the provider and health plan. If that fails, they enter the federal IDR process, where an arbitrator selects one party's proposed payment amount. Federal rules from CMS, HHS, DOL, and Treasury guide implementation, including updates in October 2021, August 2022, and December 2023. For details, see CMS rules and fact sheets and DOL guidance.

Covered Scenarios Patient Responsibility
Out-of-network emergency services In-network cost-sharing only
Air ambulance services In-network cost-sharing only
Non-emergency at in-network facilities In-network cost-sharing only

Key Exceptions and Limits

Protections do not apply to non-emergency services from out-of-network providers at out-of-network facilities. Patient consent can also waive protections: providers must give notice and obtain a signed form more than 72 hours before non-emergency services at an in-network facility.

The law excludes excepted benefits like most limited-scope dental or vision plans, flexible spending accounts (FSAs), and health reimbursement arrangements (HRAs). Uninsured patients, those on short-term plans, or Medicare/Medicaid recipients fall outside its scope--check your plan type separately.

Practical Next Steps to Dispute a Bill

Gather evidence: itemized bill, EOB from your health plan, any good faith estimate, consent forms, and service details confirming emergency status or in-network facility. Contact your health plan immediately to request they negotiate with the provider and confirm No Surprises Act applicability.

If your plan does not resolve it, ask them to initiate IDR. Escalate by filing a complaint with CMS/HHS or contact your state insurance department for plan-specific issues. Track all communications and plan deadlines. This process separates from credit card disputes or routine claims.
