The Reimbursement Fight Doctors Are Quietly Winning

All care starts and ends with physicians.

A patient has a problem. A doctor evaluates the patient, performs the operation, manages the complication, and carries the responsibility. That is the part of medicine most of us signed up for.

But between doing the work and getting paid for the work sits a wall of payer rules, benchmarks, denials, underpayments, appeals, and administrative gamesmanship. Most physicians are not trained to deal with that wall. And when doctors do not understand the payment rules, the system often uses that knowledge gap against us.

That is why the No Surprises Act is worth paying attention to. Most doctors think of it only as a patient protection law. And it is that. But it also created a process that may allow physicians to push back when insurers underpay for qualifying out-of-network care.

For too long, many insurers have counted on one simple fact: doctors are busy. When the payer sends a low payment, many practices do not have the time, staffing, data, or process to fight it.

So they accept it. And that quiet acceptance is exactly how underpayment becomes normal.

The No Surprises Act Is Not Just About Surprise Bills

The No Surprises Act protects patients from unexpected out-of-network medical bills in certain situations. That is a good and important goal. No patient should be stuck with a massive bill because of a network issue they could not control.

But the law also moved certain payment disputes away from the patient and into a formal payer-provider process. The patient is protected, but the payment question does not disappear. The doctor and insurer still have to determine what the care was worth.

That is where the Independent Dispute Resolution process, or IDR, comes in.

At a basic level, IDR allows qualifying out-of-network providers to challenge an insurer’s payment amount after an open negotiation period, where the payer and provider are meant to negotiate the payment rate prior to the need for arbitration. Both sides submit offers and supporting information, and a certified IDR entity chooses one of the offers.

In plain English, the insurer’s first number is not necessarily the final number.

IDR Is the Tool Many Physicians Still Do Not Understand

Physicians have been conditioned to believe that payer reimbursement is just something that happens to us. The payer pays what it pays. Maybe we appeal. Maybe the claim gets adjusted. Maybe it does not. Eventually, everyone moves on because the practice has another hundred problems to deal with.

But if physicians accept every low payment as inevitable, then low payment becomes the baseline. And that baseline affects cash flow, staffing, patient access, practice sustainability, and physician autonomy.

One reason IDR matters is that physicians and providers are not just theoretically able to win. They have been winning. Public reporting has shown providers prevailing in a large share of IDR determinations, with one recent analysis showing providers winning around 85% of disputes.

That does not mean every doctor should expect to win every case. Eligibility, documentation, deadlines, and execution matter a lot.

But it does suggest something important. When physician groups challenge underpayment in a structured way, they may have a real chance to recover meaningful revenue. In some cases, payment determinations can be meaningfully higher than the insurer’s initial payment or internal benchmark.

For surgeons, that should raise an important question.

What if the payer’s first number is not actually the fair value of the work?

But Winning IDR Requires More Than Being Right

Here is the frustrating part.

A physician can be completely right that a claim was underpaid. A group can be right that the payer’s offer is unreasonable. A surgeon can be right that the complexity, risk, skill, and value of a procedure are not reflected in the initial payment.

But being right is not enough.

The practice still has to identify eligible claims, start open negotiations correctly, initiate IDR on time, prepare the submission, support its offer with data, and track deadlines. And it has to do this without overwhelming an already busy administrative team.

That is where many practices lose before they ever really start. Not because their argument is weak, but because their infrastructure is weak.

And that is why a group like Allia Group can fit naturally into this conversation. This is not just a legal or billing problem. It is an operational problem. A physician group needs a process to find the right claims, build the evidence, pursue disputes, and turn outcomes into usable reimbursement intelligence.

A Practical Case Study: What IDR Could Look Like for a Surgical Code

Imagine a surgeon performs a complex autologous breast reconstruction, such as CPT 19364 for a free flap breast reconstruction, including DIEP, SIEA, or free TRAM.

This is not a minor service. It is a high-complexity operation that requires training, judgment, operative skill, perioperative management, and real risk. And according to publicly reported CMS IDR data from 2023 through Q2 2025, this code appeared 699 times, with a median reported amount of $60,000 and an 80th percentile amount of $68,200. The maximum reported amount was $230,000.

Now imagine the insurer sends an initial payment that the practice believes is far below the value of the care provided.

Historically, the practice may have had limited options. Maybe the billing team appeals. Maybe the payer adjusts the claim. Maybe nothing changes. Eventually, the practice moves on because there are patients to see and payroll to meet.

But if the claim qualifies, the practice may be able to enter open negotiation and then initiate IDR if no agreement is reached. Now the dispute is no longer just a one-sided payer decision. The surgeon’s side can submit an offer and support it with relevant information, including the nature of the service, the complexity of the case, prior contracted rates when relevant, and other allowed data.

And this is where the public IDR data becomes useful. It does not automatically prove what any one claim is worth. Every case still depends on eligibility, documentation, geography, payer, plan type, deadlines, and the facts of the service performed. But it can help a practice understand whether a payer’s initial number is wildly disconnected from what similar disputes have produced.

Why the Case Study Matters Beyond One Claim

The obvious benefit of winning an IDR dispute is more revenue for that claim.

But I think the bigger benefit may be what the process reveals.

If a payer initially pays one amount, but an independent process repeatedly determines that a higher amount is appropriate, that tells the physician group something important. It suggests there may be a meaningful gap between payer-calculated benchmarks and fair reimbursement.

That information matters beyond one code or one case. It can show which services are being underpaid, which payers are most problematic, and whether the issue is isolated or systematic. It can also help a practice understand whether its current contracts actually reflect the value of the care being delivered.

This is where IDR becomes a data tool.

The Bigger Win Is the Data Trail

One mistake I made early in my financial journey was assuming that working harder would eventually solve every money problem. But in personal finance, the numbers matter. Without those numbers, you are guessing.

The same is true in a medical practice.

If a physician group does not know where it is being underpaid, how often it is being underpaid, and how outcomes compare to contracted rates, then it is negotiating in the dark. Payers are very comfortable negotiating with doctors who are in the dark.

Successful IDR outcomes can create a data trail. They can help a physician group understand its true market value and walk into future payer negotiations with evidence instead of frustration and anecdotes.

Why This Matters for Physician Independence

Fair reimbursement affects cash flow, staffing, patient access, practice sustainability, and physician autonomy.

When payers underpay and physicians lack the tools to push back, the pressure builds. Margins shrink. Administrative burden grows. Practices consolidate. Independent physicians feel forced to sell, join larger systems, or accept payer terms that do not reflect the value of their work.

That is not just bad for doctors. It can be bad for patients too.

Physician independence is not about special treatment. It is about preserving a system where the people delivering the care have enough financial stability and professional leverage to keep doing that work well.

The Bigger Takeaway

Physicians do not need to become No Surprises Act experts. Most of us do not have the time or desire to become experts in federal payment dispute rules. That is not why we went into medicine.

But we do need to recognize when the system gives us a tool.

The IDR process may give physicians a pathway to challenge underpayment, recover revenue, build payer data, and negotiate with more leverage. For some practices, it may even open the door to serving a broader patient base while still receiving fair payment for the work being performed. 

Some surgeons have responded to years of underpayment by going cash-pay altogether, handing patients a superbill and letting them seek their own out-of-network reimbursement. It works, but it limits the practice to patients who can pay up front, and anecdotally, a credible path to fair out-of-network payment like IDR has made some of these surgeons reconsider whether that wall is still necessary. 

The key is not to assume every payer payment is final. The key is also not to assume that being right is enough. The key is to understand the opportunity, build the right process, and use the data that comes from it.

Because physicians provide the care.

And we should not be passive when the system undervalues that care.
