Balance billing occurs when a healthcare provider bills you for the difference between their charge and what your insurance pays. Under the No Surprises Act, you're protected from balance billing in many situations.

What Balance Billing Looks Like:

  • Doctor charges $1,000 for a service
  • Your insurance allows $600 and pays $480
  • Balance billing would charge you the remaining $520 ($1,000 - $480)

Federal Protections Under the No Surprises Act

Emergency Services:

  • You cannot be balance billed for emergency services at ANY facility
  • This applies whether the emergency room is in-network or out-of-network
  • You only pay your in-network cost-sharing amount

Out-of-Network Providers at In-Network Facilities:

The most common surprise billing scenario is solved by federal law:

  • You go to an in-network hospital
  • But your anesthesiologist, radiologist, or other specialist is out-of-network
  • These providers cannot balance bill you
  • You only pay your in-network cost-sharing

Covered Specialties:

  • Anesthesiologists
  • Radiologists
  • Pathologists
  • Neonatologists
  • Assistant surgeons
  • Emergency medicine physicians
  • Other specialists you don't choose

Exception - Written Consent:

  • A provider CAN balance bill if they give you written notice at least 72 hours in advance
  • You must sign a consent form acknowledging the extra costs
  • This does NOT apply to emergency services or ancillary providers
  • You can never be asked to waive rights for emergency care

State-Level Protections

Many states have additional balance billing protections beyond federal law:

Strongest State Protections:

  • New York, California, Texas, Florida, Illinois
  • Often cover ground ambulances, air ambulances
  • May have stricter notice requirements
  • Some extend to all out-of-network providers

What to Do If You Receive a Surprise Bill

Step 1: Don't Pay Immediately

  • Review the bill carefully
  • Check if the No Surprises Act applies
  • Look for signs of balance billing

Step 2: Contact Your Insurance

  • Call the customer service number
  • Explain you believe this violates surprise billing protections
  • Ask them to reprocess the claim under No Surprises Act rules

Step 3: Contact the Provider Use this script: "I received a bill for $[AMOUNT] for services on [DATE]. I believe this violates the No Surprises Act balance billing protections. I should only owe my in-network cost-sharing amount."

Step 4: File a Federal Complaint

  • Visit cms.gov/nosurprises
  • Call 1-800-985-3059
  • File within one year of receiving the bill

Step 5: Contact Your State Many state insurance departments have additional enforcement powers and can help resolve disputes faster than federal agencies.

Important: Balance billing protections apply to the vast majority of surprise bills, but you need to know your rights and act on them.
