What Is Balance Billing (Surprise Billing)?

Balance billing occurs when an out-of-network provider bills you for the difference between their charge and what your insurance paid. The No Surprises Act now protects patients in many situations.

How Balance Billing Happens

  1. You receive care from an out-of-network provider (sometimes unknowingly)
  2. Your insurance pays their allowed amount (e.g., $500)
  3. The provider's charge is higher (e.g., $2,000)
  4. The provider bills you for the "balance" ($1,500)

No Surprises Act Protections

Since January 2022, you're protected from balance billing for:

  • Emergency services at any facility
  • Non-emergency services from out-of-network providers at in-network facilities
  • Air ambulance services from out-of-network providers

What You Owe

Under the No Surprises Act, you only pay:

  • Your in-network cost-sharing (copay, coinsurance, deductible)
  • The provider and insurer must negotiate the rest

How to Dispute a Balance Bill

  1. Check if the No Surprises Act applies
  2. Call your insurer and ask them to reprocess at in-network rates
  3. Contact the provider's billing department and cite the law
  4. File a complaint with CMS (cms.gov/nosurprises) or your state
  5. Request independent dispute resolution if needed

Frequently Asked Questions

Does the No Surprises Act apply to all insurance?

It applies to most private insurance plans (employer-sponsored, marketplace, individual). It does NOT apply to Medicare, Medicaid, TRICARE, VA, or Indian Health Service — though these programs have their own protections.

What if I get a balance bill anyway?

Contact your insurer and the provider to dispute it. File a complaint at cms.gov/nosurprises or call 1-800-985-3059. Many states also have their own surprise billing laws with additional protections.
