The Financial Crisis in Emergency Medicine: A Deep Dive

By Elena Pak, Credentialing Department, WCH

Emergency physicians save lives in minutes. Payers take months to claw back what they paid. And algorithms are making it worse.

There is a quiet financial crisis unfolding inside America’s emergency departments. It doesn’t make headlines the way drug prices or hospital mergers do. But for the physician groups who staff the ERs that treat your heart attack, your car accident, your child’s broken arm at 2 a.m., it is an existential threat — and it is accelerating.

The culprit is not a single policy. It is a convergence: a structural shift in how emergency medicine visits are coded, a wave of payer losses that triggered corporate panic, and the deployment of opaque AI systems designed to reduce reimbursement at industrial scale. The result is a system in which the very physicians who bear the highest clinical and legal risk are increasingly unable to collect payment that reflects the work they actually did.

How We Got Here: Thirty Years in Five Paragraphs

To understand the current crisis, you have to understand how emergency medicine billing evolved — because the seeds of today’s conflict were planted decades ago.

In the early 1990s, emergency physicians documented encounters on carbon-copy paper forms. Billing was limited by legibility. If the third copy of a form was unreadable, the claim reflected a lower level of service than the one actually delivered. Physicians were systematically underpaid, not by design, but by infrastructure.

The 1995 CMS coding guidelines tried to fix that. They introduced quantitative documentation requirements: specific numbers of history elements, physical exam components, and decision-making criteria. Miss one element, and a Level 5 visit became a Level 4. The system was rigid and mechanical, but it was legible. Payers and providers operated from the same rulebook.

Over the following decades, electronic health records changed everything. Documentation became richer, more complete, more structured. A fuller record of what physicians actually did — the diagnostic reasoning, the risk assessment, the management decisions — could finally be captured. Naturally, coded acuity levels shifted upward. This wasn’t fraud. It was documentation finally catching up to clinical reality.

Then, in 2023, CMS updated the E/M coding guidelines again. The new framework deprioritized the volume of history and exam elements in favor of medical decision-making complexity: How difficult was the diagnostic problem? How much data did the physician review? How risky was the management decision? Under this model, many visits that had been appropriately coded as Level 3 under the old system now legitimately supported Level 4 coding. The American Academy of Professional Coders predicted the shift. The shift happened.

And payers noticed.

The Payer Crisis and the Convenient Scapegoat

Beginning around 2022–2023, several major insurers reported disappointing financial results. Major payers such as Aetna, Centene, and UnitedHealthcare reported disappointing earnings, often citing rising medical costs and increased severity in billed services — fallout that contributed to high-profile leadership changes, including executive turnover at Aetna and substantial management changes at UnitedHealthcare.

Faced with shareholder pressure, payers needed a narrative. They found one: provider upcoding. Studies from groups like the Peterson-KFF Health System Tracker and Trilliant Health highlighted upward shifts in billing codes across certain diagnosis groupings. Payers amplified these findings, publicly vowing to address “rising costs” caused by providers. What they were less forthcoming about was that the coding shift was largely legitimate — the predictable, documented result of a regulatory framework change that CMS itself had implemented.

But the narrative had taken hold. And with it came the tools.

The Algorithm as Auditor

The term “prior authorization” has been in the healthcare lexicon for years. What is happening now is different. Payers are now deploying software to automatically flag and downcode claims based on final diagnoses or predictive analytics. These systems don’t read the chart. They don’t evaluate the clinical reasoning. They look at the discharge diagnosis and work backward, applying retrospective logic to decisions that were made in real time, under uncertainty, by a physician who didn’t yet know what the patient had.

This is the central absurdity at the heart of diagnosis-based downcoding: emergency medicine is definitionally practiced in the absence of diagnostic certainty. A patient who arrives with crushing chest pain, diaphoresis, and an abnormal EKG requires the full workup for a STEMI — regardless of whether the final diagnosis turns out to be a STEMI, a pulmonary embolism, or severe GERD. The physician’s cognitive labor, the risk management, the resource utilization — all of it happens before the answer is known. Payer algorithms that evaluate the encounter based only on the final diagnosis are, by design, blind to the most clinically and financially relevant parts of the visit.

The scale of these tools is staggering. A 2024 Senate report cited by the AMA found that AI-driven denial tools can reject claims at rates up to 16 times higher than traditional review processes. UnitedHealthcare deploys the Optum EDC Analyzer. Elevance Health-affiliated plans, including many Blue Cross Blue Shield plans, use Cotiviti. The specific logic of these systems is proprietary — not disclosed to physicians, not subject to external audit, not explainable in any clinical terms. They are, in the parlance now widely used across the industry, black boxes.

LANE Lists: When a Diagnosis Becomes a Denial

One of the most aggressive tactics is the deployment of Low-Acuity Non-Emergent (LANE) lists — curated lists of diagnoses that payers have decided are not “real” emergencies and therefore don’t merit full emergency-level reimbursement. Headaches. Urinary tract infections. Back pain. Minor lacerations.

The logic sounds superficially reasonable. Why pay emergency rates for something that could have been handled at urgent care? But the logic collapses under clinical scrutiny. A headache in the emergency department might be a tension headache — or it might be a subarachnoid hemorrhage. The physician doesn’t know which until the workup is complete. The same applies to chest pain, abdominal pain, dizziness, and dozens of other “low-acuity” presentations that can mask life-threatening conditions.

LANE-based downcoding — utilized by major payers including Kaiser Permanente in Washington, Upper Peninsula Health Plan in Michigan, Horizon Blue Cross Blue Shield in New Jersey, and Providence Health Plan in Oregon — fundamentally ignores the resource-intensive workup often required to rule out life-threatening conditions before a minor diagnosis can be confirmed.

The physician who spends two hours ruling out a pulmonary embolism in a patient who ultimately has a muscle strain gets paid for a muscle strain.

The Numbers Behind the Crisis

The financial data is unambiguous. A RAND Corporation study analyzing over 50 million emergency medicine professional claims from 2018 to 2022 found that out-of-network reimbursement fell 47.7%, in-network reimbursement dropped 10.9%, and Medicare payments declined 3.8% during the study period alone. Adjusted for inflation, Medicare payments to emergency physicians are effectively down more than 30% compared to 2001.

Meanwhile, facility payments to hospitals increased more than 18% over that same period. Hospitals receive annual adjustments tied to inflation. Physician payments largely do not. The structural asymmetry is not accidental — it is baked into the reimbursement architecture.

The 2025 Medicare Physician Fee Schedule conversion factor dropped 2.83%, the fifth consecutive annual reduction, representing a cumulative cut of nearly 12% over five years. According to the American Hospital Association, Medicare paid only 82 cents for every dollar hospitals spent on patient care in 2022 — a shortfall approaching $100 billion. Emergency departments, serving a disproportionately Medicare and Medicaid population with rising acuity levels, absorbed an outsized share of that gap.

The payment enforcement mechanisms that do exist are not working. A 2024 EDPMA member survey found that 59% of No Surprises Act arbitration rulings were not paid within the required 30-day window, and 26% were underpaid. Payers are not being held accountable even when they lose.

The No Surprises Act: Promise and Betrayal

The No Surprises Act, which took effect in 2022, was supposed to protect both patients and physicians from the worst outcomes of surprise billing. For patients, it largely succeeded: patients are no longer exposed to catastrophic out-of-network bills for emergency care. For physicians, the story is more complicated.

The NSA created an Independent Dispute Resolution (IDR) process for contested claims. Early implementation of that process was heavily tilted toward payers — initial rules anchored arbitrators to the Qualifying Payment Amount (essentially the payer’s own benchmark) in ways that disadvantaged providers. A series of lawsuits by the Texas Medical Association (TMA) have partially corrected this, making IDR more viable for physician groups willing to invest in the process.

But IDR is not free. It requires administrative infrastructure, legal expertise, and sustained organizational capacity. For small and independent emergency medicine groups — already under financial pressure — the cost-benefit calculus is difficult. In July 2025, Congressman Greg Murphy introduced a bipartisan bill aimed at closing enforcement gaps through increased penalties and transparency requirements, a signal that Congress is beginning to grasp the depth of the problem. Whether that legislation advances remains to be seen.

The Structural Trap for Independent Groups

The crisis is not uniform across the emergency medicine landscape. Large health systems have buffers: facility revenue streams, scale advantages in payer contracting, legal resources, and political leverage. Independent emergency medicine groups — the physician-owned practices that staff many community hospitals — have none of these.

Because independent groups operate outside hospital systems, they have no access to facility revenues, leaving them fully exposed to the impact of declining professional payments. A hospital can absorb a 10% decline in professional fees for the ER because it collects facility fees on every visit. An independent physician group cannot.

This structural asymmetry creates a slow-motion consolidation pressure. Independent groups that can no longer sustain their economics are acquired by large staffing companies or hospital-employed models. Physician autonomy shrinks. The diversity of practice models — which research consistently associates with better patient outcomes and more adaptive care delivery — erodes.

There is also a more immediate consequence: physician burnout. When emergency physicians spend increasing amounts of time and energy fighting automated denials, appealing downcoded claims, and justifying clinical decisions to algorithms that cannot understand them, the administrative burden compounds the already extreme cognitive and emotional demands of emergency medicine. Recruitment and retention suffer. Staffing gaps follow.

What Needs to Change

The current trajectory is not sustainable, and the solutions are not complicated — though they are politically difficult.

First, algorithmic denial tools must be subject to transparency requirements. If a payer’s AI system is making clinical coverage determinations, the logic of that system should be available for external audit. The “black box” defense — we can’t explain why claims are being denied because our algorithm is proprietary — is incompatible with any serious conception of payment integrity or due process.

Second, diagnosis-based downcoding must be prohibited or strictly regulated. Several states have moved in this direction. Arkansas and Virginia adopted new downcoding laws in 2025, while Ohio, New York, Connecticut, New Jersey, and Utah are debating similar measures. Federal action would be more efficient and more durable.

Third, the Medicare Physician Fee Schedule must be restructured to include inflation adjustments. A reimbursement system that loses 30% of its real value over two decades is not a payment system — it is a slow-motion defunding of the physician workforce that staffs America’s emergency departments.

Fourth, No Surprises Act enforcement must have teeth. A process where 59% of rulings go unpaid within the required window is not enforcement — it is theater.

The Broader Stakes

Emergency medicine is not like other medical specialties. The emergency department is the one part of the American healthcare system that cannot say no. EMTALA requires that every patient who presents to an ED be evaluated and stabilized, regardless of insurance status, ability to pay, or time of day. Emergency physicians take on clinical, legal, and ethical obligations that no other specialty assumes in the same unconditional way.

The payer playbook currently in operation — opaque algorithms, diagnosis-based denials, black-box audits, LANE lists — treats emergency care as just another cost center to be optimized. It is not. It is the safety net beneath the entire system. When that net frays, the consequences are not abstractions. They are patients who can’t get care, communities that lose their ER, and physicians who leave a specialty they trained for because the economics no longer add up.

The algorithmic squeeze is real. The data is clear. The question is whether the policy response will be commensurate — or whether it will arrive, as emergency medicine responses usually do, only after the damage is already done.
