Out-of-network billing used to be a straightforward back-office task. Submit the claim, wait for the payer’s response and bill the patient for the balance. But the No Surprises Act changed that in 2022. Providers can no longer send balance bills to patients in most emergency and facility-based scenarios. This means the entire financial recovery now depends on what happens between the provider and the payer, not between the provider and the patient anymore.

And here starts the problem as much legitimate revenue never makes it back to the practice for:

• Payers routinely send low initial offers, betting that providers won’t push back
• Negotiations require documentation that many billing teams simply don’t track
• The Federal Independent Dispute Resolution (IDR) process runs on strict deadlines
• Missing one piece of information closes the door on recovering a claim entirely
• Inconsistent payer rules across commercial insurers and self-funded plans

With all these complications, you really need expertise and so CollectionPro exists to close that gap. Our team here specializes in out-of-network claim recovery. Be it from eligibility checks through Federal IDR arbitration to post-award collection, we do it all so providers get paid what they actually earned, not what a payer decided to offer.

What Does Out-of-Network Billing Really Mean?

The difference between in-network and out-of-network billing can be confusing for many. The major difference between the two is in-network billing runs on a contract where the provider and the payer have already agreed on all the rates. So the claim moves through a predictable and largely automated process. On the other hand, out-of-network billing has no such agreement. There are no negotiated rates to fall back on; no pre-set fee schedules; and consequently, no guarantee the payer will treat the claim the same way twice. That’s exactly why it demands specialized expertise, as every claim has to be built, priced, and defended individually.

So, one might ask, can the providers be reimbursed for out-of-network care?

The answer is definitely yes. The providers can get fully reimbursed for out-of-network care, depending on how the claim is structured, handled and under which law it is appealed. Before the No Surprises Act, a patient might pay the provider directly and then file a reimbursement claim with their insurer. Today, the Act covers emergency care and certain facility-based services, and the patient’s responsibility is capped, shifting the matter of settling the financial dispute almost entirely to the provider and the payer.

Commercial insurers and self-funded plans don’t always play by the same rules either. Self-funded plans, which are regulated under ERISA (Employee Retirement Income Security Act) rather than standard state insurance laws, can have different appeal timelines and documentation requirements. That inconsistency is one more reason a generic billing process falls short for out-of-network work.

Terminology Used in Out-of-Network Medical Billing

OON billing is comparatively new for many and it comes with its own vocabulary. So providers who are unaware of the rudiments might lose out on their money. Here are a few terms they should know:

• Out-of-Pocket Costs (OOP) – Signifies the amount the insurance company doesn’t cover but has to be borne by the patient. It adds up all the deductibles, copays and coinsurance into one balance cost after insurance has paid its share.
• Deductible – Every plan year starts the same way: the patient pays first. Until they’ve paid a set amount out of their own pockets, insurance doesn’t chip in at all. Once that number is hit, coverage kicks in.
• Coinsurance – This is the split that happens after the deductible has been paid off. The bill gets divided by percentage and a common setup is 80/20, where the insurer covers 80% and the patient is responsible for the rest.
• Copayment (Copay) – It is the flat fee, paid on the spot. Whether it’s a $25 visit to the primary care physician or a $400 specialist appointment, the copay doesn’t move. It’s the one part of medical billing that’s actually predictable.
• Superbill – It is an elaborate, itemized bill covering diagnoses, procedures and charges that gets sent to the insurer by the provider.
• EMTALA (Emergency Medical Treatment and Labor Act) – Mainly started in the year 1986, this act prohibits hospitals with an ER to turn someone away or delay treatment because of financial or insurance reasons. Doctors have to screen and stabilize the patient first. Note: EMTALA doesn’t pertain to billing which happens later once the emergency has been handled.
• AB 72 (California’s Out-of-Network Billing Law) – California passed this to close a specific loophole: a patient goes to an in-network hospital, gets treated, and later finds out the doctor who saw them wasn’t actually in-network. Under AB 72, the patient still only pays their normal in-network rate. The provider and the insurer are left to settle the balance between them.
• No Surprises Act (NSA) – Same idea as AB 72, but on a wider, federal plane. It has been in effect since the start of 2022 and covers most emergency situations, along with some non-emergent cases, where an out-of-network provider treats someone at an in-network facility. The patient’s bill stays capped at the in-network rate.
• Balance Billing – This is the practice both AB 72 and the No Surprises Act were enacted to stop. It’s when a provider charges the patient for whatever the insurance company didn’t pay — the gap between the provider’s rate and the insurer’s rate.
• Qualifying Payment Amount (QPA) – The benchmark rate insurers use to calculate patient cost-sharing under the No Surprises Act. Payers frequently anchor their initial offers to this figure, which is one of the major reasons such offers tend to run low.
• Open Negotiation Period – The 30 business day window after an initial payment or denial during which the provider and payer can negotiate directly, before either party can file for Federal IDR.

Out-of-network billing laws are solely designed to protect patients from any kind of unexpected medical bills when they have little or no choice over who provides the medical care they need. The No Surprises Act and similar state laws, in fact, prevent patients from being ‘balance’ billed for most emergency services and certain non-emergency services provided by out-of-network clinicians at in-network facilities. So, instead of leaving patients responsible for payment disputes, these laws establish clear guidelines for how providers and insurers determine reimbursement while limiting the patient’s financial responsibility to applicable in-network cost-sharing.

Notice and Consent: When Balance Billing Is Still Allowed

Here, the NSA carves out a narrow exception. In certain non-emergency situations, a provider can ask a patient to waive their balance billing protections but only under strict conditions. Such a notice, however, must be in writing, disclose the provider’s non-participating status, list in-network alternatives the patient could have chosen, and include a good-faith estimate of charges. It also must be provided at least 72 hours before a scheduled service, or at least 3 hours beforehand if the service was scheduled on a shorter notice.

This exception has hard limits, though. Notice and consent cannot be used for emergency services before a patient is stabilized, for unforeseen urgent medical needs, or for post-stabilization services unless additional requirements are met. On the non-emergency side, ancillary services like anesthesiology, pathology, radiology, neonatology and diagnostic services can never be waived, regardless of who provides them. A hospital can’t obtain a signed waiver from the anesthesiologist and call the claim settled; that specialist remains protected no matter what the patient signs.

State Law Still Matters in Out-of-Network Billing

In case of managing OON billing, federal NSA supplements state-specific surprise billing laws rather than replacing them, and where a state’s law offers protections at least as strong as the federal rules, the former generally applies. That means the arbitration process for every provider can look very different depending on where the claim originates.

New York, New Jersey and Texas are the clearest examples. All three have state arbitration systems that allow consideration of billed charges or ‘usual and customary’ charges factors – areas where the federal IDR process is expressly barred from weighing.

Also, ambulance transport is a good example of the specificities of NSA’s protection that extends to air ambulance services but not ground ambulance transport, leaving that coverage to a patchwork of state rules. Further, some states protect against it comprehensively, some only for private (non-municipal) providers, and some not at all. An out-of-network biller, who doesn’t track which rule applies where, can misprice a claim before it is even submitted.

The practical takeaway therefore is, out-of-network billing isn’t one national process running on one set of rules. It’s a federal floor with state-level and plan-level variations layered on top, and knowing which layer applies to a given claim is often the difference between a full recovery and a partial one. And that, undoubtedly, requires expert support.

Why Do Patients Choose Out-of-Network Care?

Patients may choose out-of-network providers for multiple reasons. And while out-of-network care can result in higher out-of-pocket costs, many patients still consider the accompanying benefits worth the additional expense. In fact, there are patients looking to have access to specialized expertise, receive treatment sooner, continue care with a trusted physician, or even obtain services that are not available within their insurance network are some of the common reasons here.

5 Reasons Why Out-of-Network Claims Often Result in Lost Revenue

Even when a claim is legitimate and well-documented, a surprising amount of reimbursement never reaches the provider. Here’s where it usually goes wrong.

1. Incorrect reimbursement calculations – Payers calculate allowed amounts using their own internal logic, and that logic isn’t always applied correctly or fairly. Without a team checking the math against usual and customary rates, errors go unnoticed and unchallenged.
2. Low initial payer offers – Insurers have little incentive to offer a fair rate on the first pass. Many providers accept that first number simply because pushing back feels like more trouble than it’s worth. It usually isn’t.
3. Missed appeal opportunities – Appeal windows are short, and once they close, so does the opportunity to recover that claim. Practices juggling high claim volumes often let these deadlines slip by without realizing it.
4. Incomplete documentation – Federal IDR arbitration runs on evidence. Missing medical records, unclear coding, or absent QPA comparisons weaken a case before it even gets in front of an arbitrator.
5. Missed Federal IDR deadlines – The IDR process has firm timelines for initiating a dispute after the open negotiation period ends. Miss that window, and the claim is effectively closed for good, regardless of how strong the underlying case was.
