Marcus had a heart attack at 2am on a Saturday. The paramedics took him to the nearest hospital — which happened to be out of network. He had no choice. He was unconscious.
Three months later he received a bill for $34,000 — the difference between the hospital’s charges and what his insurer paid at out-of-network rates. The insurer said the hospital was out of network and the claim was processed accordingly.
This is illegal. Under federal law — reinforced by the No Surprises Act — emergency care cannot be subject to higher cost-sharing than in-network care, regardless of whether the facility is in your network. The insurer knew this. They processed the claim incorrectly and waited to see if Marcus would pay.
In New Jersey I have watched this happen to heart attack patients, stroke patients, and accident victims. People who had no ability to choose their hospital, facing bills they were legally protected against, paying because nobody told them the law.

What Actually Happened to Marcus in Georgia
Marcus’s situation illustrates why knowing your state’s specific law — and the federal protections that apply to everyone — is the difference between paying a bill you legally do not owe and getting it corrected.
The resolution came not from the insurer voluntarily correcting the error, but from Marcus filing a formal complaint with the state insurance department. The complaint was opened. The insurer was contacted. The processing error was identified and corrected. The $34,000 balance was reduced to the in-network cost-sharing amount.
The complaint took 20 minutes to file online. It saved Marcus tens of thousands of dollars on a bill that was illegal under both state and federal law.
Step by Step — What to Do If Your Claim Was Denied or Incorrectly Processed
Step 1 — Get the denial letter and identify the stated reason. The insurer must provide a written explanation. If the reason is out-of-network status for emergency care, that is the specific violation to challenge.
Step 2 — Write a formal dispute letter to the insurer. Cite the No Surprises Act, your state’s specific law from the table above, and the specific provision that prohibits what they did. Request correction of the claim processing within 30 days.
Step 3 — File a complaint with your state insurance department. Every state has an online complaint portal. Use it. State regulators contact insurers and require explanations for violations — most insurers correct processing errors when regulators inquire.
Step 4 — File a No Surprises Act complaint with CMS. Go to cms.gov/nosurprises. This is the federal enforcement channel and it runs independently of any state complaint.
Step 5 — File an internal appeal followed by external review if the dispute is not resolved. Denial of an emergency claim that should have been covered at in-network rates is an appealable adverse determination. Internal appeal followed by external review are available for all covered services.
Questions People Ask
Can my insurer deny an ER claim because I should have known the hospital was out of network?
No. Federal law and most state laws use a “prudent layperson” standard — if a reasonable person would have believed their symptoms required emergency care, the insurer cannot deny coverage based on network status. The standard is what a reasonable person would do in the emergency situation, not what the insurer thinks should have been done differently.
What is the difference between a claim denial and balance billing?
A claim denial means the insurer refused to pay anything. Balance billing is when the insurer paid their portion and the out-of-network provider bills you the balance — the difference between the provider’s full charge and what the insurer paid. Both are prohibited for emergency care under the No Surprises Act, though through different mechanisms. A claim denial is challenged through the appeals process. Balance billing is challenged directly with the provider and through a complaint with CMS.
The hospital says I agreed to pay out-of-network rates when I was admitted. Is that binding?
Probably not for emergency care. Consent forms signed during an emergency — when you may be in acute distress, under medication, or unconscious — cannot override federal and state law protections. The No Surprises Act specifically addresses this — it requires separate, explicit consent forms that meet specific requirements before a provider can bill out-of-network rates for non-emergency services. A blanket admission consent form does not meet those requirements.
