Out-of-Network Surgery Costs: How to Avoid the Trap

You schedule a procedure at an in-network hospital. You confirm with the front desk that your insurance is accepted. Weeks later, a bill arrives for thousands of dollars — because the anesthesiologist, the assistant surgeon, or the pathology lab that processed your tissue sample was out of network. This scenario is surprisingly common, and it can turn an already stressful medical experience into a financial crisis.

Out-of-network surgery costs are one of the most poorly understood aspects of the American healthcare system. This article explains how these costs arise, what protections exist, and how to protect yourself before, during, and after a procedure.

How Out-of-Network Charges Happen — Even at In-Network Hospitals

Many patients assume that if the hospital is in network, everything associated with their visit is covered. Unfortunately, that is not always the case. A single surgical procedure can involve five or more separate providers, each billing independently:

• The primary surgeon — May be in network, but not always.
• The assistant surgeon — Often assigned by the hospital and may not be in your plan's network.
• The anesthesiologist — Frequently employed by a separate anesthesia group that may not participate in your plan.
• The pathologist — If tissue is sent for analysis, the pathologist reviewing it may be out of network.
• The radiologist — Imaging interpretation is often handled by a separate group.
• The facility itself — Even if the surgeon is in network, the surgical center may be a different entity with a separate network status.

Each of these providers can generate a separate bill, and any one of them being out of network can result in unexpected charges.

Balance Billing: The Core Problem

When an out-of-network provider treats you, they are not bound by the negotiated rates your insurer has with in-network providers. The provider can charge their full fee and then bill you for the difference between what your insurance pays and what they charged. This practice is called balance billing.

For example, if an out-of-network anesthesiologist charges $5,000 and your insurance company determines the "usual and customary" rate is $2,500, the insurer pays its share of $2,500, and the anesthesiologist bills you for the remaining $2,500. You had no choice in selecting this provider, yet you are responsible for the gap.

The No Surprises Act: Federal Protection Against Surprise Bills

Effective January 2022, the No Surprises Act provides federal protection against surprise medical bills in specific situations:

What the Act Covers

• Emergency services at out-of-network facilities — You cannot be balance-billed for emergency care.
• Out-of-network providers at in-network facilities — If you receive non-emergency care at an in-network hospital, any out-of-network provider involved in your care (such as an anesthesiologist or radiologist) cannot balance-bill you.
• Air ambulance services — Balance billing for air ambulance transport is prohibited.

What the Act Does Not Cover

• Ground ambulance services — These remain subject to balance billing in most states.
• Facility-level charges — If the entire hospital or surgical center is out of network, the No Surprises Act may not protect you from the facility fee.
• Planned out-of-network care — If you voluntarily choose an out-of-network surgeon and facility, the Act's protections do not apply.

Understanding these gaps is essential. The No Surprises Act offers meaningful protection, but it does not eliminate all out-of-network financial risk.

Gap Exceptions and Continuity of Care Provisions

Some insurance plans offer gap exceptions — provisions that allow out-of-network providers to be treated as in-network when no in-network provider is available for the service you need. This is most common in rural areas or for highly specialized procedures.

To request a gap exception:

• Contact your insurance company before the procedure.
• Demonstrate that no in-network provider within a reasonable distance can perform the procedure.
• Ask for a formal "network gap exception" or "in-network waiver" in writing.
• Keep documentation of the approval for your records.

If approved, the out-of-network provider agrees to accept in-network rates, and your cost sharing is calculated accordingly.

How to Protect Yourself Before Surgery

Proactive steps can help you avoid out-of-network surprises:

• Ask for a full provider list. Before scheduling, request the names and NPI numbers of every provider who will be involved in your care — surgeon, assistant, anesthesiologist, radiologist, pathologist.
• Verify each provider's network status. Call your insurer or check their online directory for each individual provider. Do not rely solely on the hospital's assurance that "we accept your insurance."
• Request a good-faith estimate. Under the No Surprises Act, uninsured and self-pay patients are entitled to a good-faith estimate of expected charges. Even if you are insured, asking for one can help you identify potential out-of-network charges.
• Get pre-authorization. Ensure your insurer has approved the procedure and confirm in writing which providers are covered.
• Document everything. Keep records of every phone call, including the name of the representative, the date, and what was confirmed.

What to Do If You Receive a Surprise Bill

If you receive an unexpected out-of-network bill despite taking precautions:

• Do not pay immediately. Review the bill against your Explanation of Benefits (EOB) to verify the charges.
• Check if the No Surprises Act applies. If the out-of-network provider treated you at an in-network facility, balance billing may be illegal in your case.
• File a complaint. If you believe the bill violates the No Surprises Act, file a complaint with the federal No Surprises Help Desk or your state Department of Insurance.
• Negotiate. If the bill is legitimate, negotiate with the provider. Many will reduce the charge if you offer a lump-sum payment or demonstrate financial hardship.

State-Level Surprise Billing Protections

In addition to the federal No Surprises Act, many states have enacted their own surprise billing laws that may offer broader protections than federal rules. As of 2025, more than 30 states have passed some form of surprise billing legislation. These laws vary significantly in scope:

• Scope of coverage: Some state laws apply to all state-regulated plans, including HMOs and PPOs, while others apply only to certain plan types.
• Ground ambulance protections: While the federal No Surprises Act does not cover ground ambulance balance billing, several states — including Colorado, Illinois, and New York — have enacted their own protections for these services.
• Payment dispute resolution: Many states have established independent dispute resolution processes that determine how much insurers must pay out-of-network providers, removing the patient from the middle of the negotiation.
• Notice and consent requirements: Some states require providers to notify patients in advance if they will be treated by an out-of-network provider and obtain written consent before proceeding.

Check with your state's Department of Insurance or your state legislature's website to determine what protections apply in your jurisdiction. In some cases, state law may provide stronger protection than the federal No Surprises Act.

A Real-World Example

James, a 56-year-old accountant from Minneapolis, scheduled a routine knee arthroscopy at an in-network hospital. He verified with both the hospital and his insurer that the facility and his surgeon were in network. After the procedure, he received a bill for $4,200 from the assistant surgeon — who, it turned out, was employed by a separate practice group that did not participate in James's insurance plan. Because the assistant surgeon was an out-of-network provider at an in-network facility, James invoked the No Surprises Act and filed a complaint. The bill was ultimately withdrawn. But the experience illustrates how easily out-of-network charges can surface, even when patients take reasonable steps to verify coverage.

Not every patient is as fortunate. When the surprise bill falls outside the No Surprises Act's protections — for instance, when the entire facility is out of network — patients may face limited options and significant financial pressure.

The Transparency Gap: US Pricing vs. International Models

One of the most frustrating aspects of out-of-network surgery costs in the United States is the lack of price transparency. Patients often cannot determine the full cost of a procedure until after it is completed and the bills arrive. Each provider bills separately, codes are subject to interpretation, and the final amount depends on a negotiation between the insurer and each entity involved.

This stands in sharp contrast to how many accredited international hospitals operate. In established medical travel destinations, hospitals routinely provide a single, comprehensive quote before the patient arrives. This quote typically includes:

• Surgeon and assistant surgeon fees
• Facility and operating room charges
• Anesthesia
• Implants, devices, and supplies
• Post-operative care and follow-up visits
• Recovery accommodation and transfers

The patient receives one price, in writing, before committing. There are no separate bills from five different entities, no surprise charges for an out-of-network provider they never chose, and no weeks-long process of reconciling multiple EOBs.

For patients who have experienced the frustration of opaque US billing, the clarity of an all-inclusive international quote can be a significant relief.

Key Takeaways

• Out-of-network charges can come from any provider involved in your surgery, even at an in-network hospital.
• Balance billing can add thousands of dollars to your costs, and the No Surprises Act does not cover every situation.
• Verifying every provider's network status before surgery is the most effective way to avoid surprises.
• Gap exceptions may be available if no in-network provider can perform your procedure.
• International hospitals often provide transparent, all-inclusive pricing that eliminates the uncertainty inherent in US medical billing.
