7 Tactics Insurance Companies Use to Underpay Physicians — And How to Fight Back

QPA Manipulation: Rigging the Baseline

The Qualifying Payment Amount (QPA) is supposed to represent the median in-network rate for a given service in a given geographic area. Under the No Surprises Act, the QPA serves as a key reference point in Independent Dispute Resolution (IDR). Insurance companies know this—and they've turned QPA calculation into an art form of minimization.

Here's how it works. Insurers are responsible for calculating their own QPAs. They select which contracts to include in the median calculation, and they consistently cherry-pick the lowest-paying agreements while excluding higher-rate contracts. They use narrow geographic definitions—sometimes splitting a single metropolitan area into multiple sub-regions—to reduce the pool of comparable rates. They calculate medians rather than means, which naturally suppresses the impact of higher-value contracts. And they exclude outlier payments that would pull the number upward.

The result? A physician who provides emergency anesthesia services billed at $4,200—a rate consistent with regional market data—receives a QPA-based offer of $1,800. The insurer's QPA calculation excluded the three highest-paying contracts in the region and used a geographic boundary that grouped urban specialists with rural practitioners two hours away.

A 2024 report by the American Society of Anesthesiologists found that insurer QPAs were on average 47% below independently verified market rates for the same services in the same regions. CMS has acknowledged the opacity of QPA calculations but has done little to enforce transparency.

Delay and Deny: The Attrition Strategy

The insurance industry's most profitable tactic doesn't require complex algorithms or legal theories. It relies on a simple bet: if you deny a claim, most physicians won't fight it. And that bet pays off handsomely.

The strategy is executed in layers. First, the claim is denied on a technicality—missing authorization number, incorrect modifier, lack of "medical necessity" documentation. The denial letter arrives 30 to 60 days after submission, often with vague language that makes it difficult to identify the actual issue. The physician's billing department, already stretched thin, must now research the denial, gather additional documentation, and resubmit.

If the claim is resubmitted, the insurer deploys the second layer: delay. The resubmission "requires additional review." Another 30 to 45 days pass. A second request for documentation arrives. The cycle repeats. Each iteration costs the physician's practice $25 to $118 in administrative expenses per claim, according to CAQH research. Meanwhile, the insurer earns investment returns on retained funds.

Results shown are illustrative examples and vary based on claim specifics, payer behavior, and documentation quality. Past outcomes do not guarantee future results.

Downcoding: Paying for Less Than You Delivered

Downcoding is the practice of reimbursing a claim at a lower CPT code than what was actually billed, effectively paying the physician for a simpler, less expensive service than what was provided. It's one of the most insidious tactics because it's disguised as a routine adjudication decision.

Here's a common scenario: an emergency physician evaluates a patient presenting with chest pain, abnormal vitals, and a complex medication history. The encounter involves a comprehensive history, detailed examination, and high-complexity medical decision-making. The physician correctly bills CPT 99285—the highest-level emergency department evaluation code. The insurer reimburses at 99283 rates, a mid-level code representing moderate complexity.

Insurers justify downcoding through automated clinical edit systems that apply rigid criteria to complex clinical encounters. These systems flag claims based on keyword analysis of medical records, ignoring the nuanced clinical judgment that determined the actual level of service. The AMA has documented that up to 25% of high-complexity emergency claims are downcoded by at least one level, with certain payers downcoding at rates as high as 40%.

The tactic is particularly devastating for emergency medicine physicians, anesthesiologists, and surgeons who routinely perform high-complexity procedures. Over time, systematic downcoding can reduce a physician's effective reimbursement by 15% to 30% compared to what their documentation supports.

Bundling and Unbundling: Rearranging the Math

Bundling and unbundling are opposite sides of the same coin, and insurers use whichever approach reduces the payout. Improper bundling combines separately billable procedures into a single, lower-paying code. Improper unbundling splits a complete service into individual components, each paid at a lower rate than the whole.

Insurers rely on the National Correct Coding Initiative (CCI) edits to justify their bundling decisions. But here's what most physicians don't realize: CCI edits are guidelines, not absolute rules. Many CCI edits include modifier indicators that allow separate billing when the procedures are truly distinct and independently documented. Insurers routinely ignore these modifier exceptions, bundling claims that are legitimately billed separately.

The financial impact is significant. The American Hospital Association estimates that improper bundling and unbundling practices cost providers an estimated $2.7 billion annually. For individual practices, this can represent 5% to 12% of total revenue from affected payers.

Network Adequacy Gaming: Engineering the OON Trap

This tactic operates at a structural level. Insurance companies are required by federal and state law to maintain adequate provider networks—meaning they must have enough in-network specialists to serve their members. But "adequate" is a loosely defined standard, and insurers have become experts at meeting the letter of the law while violating its spirit.

Here's the playbook: An insurer contracts with the bare minimum number of in-network emergency physicians, anesthesiologists, or radiologists in a region. When patient volume exceeds the capacity of those in-network providers—which happens predictably and frequently—patients are treated by out-of-network physicians. The insurer then pays the OON physician at a fraction of the fair market rate, often using a QPA that reflects the cherry-picked in-network rates described above.

The insurer benefits twice: they save on network contracting costs by maintaining a thin network, and they save on reimbursement by paying OON rates below fair value. The physician, who had no choice but to treat the patient, absorbs the loss. CMS has issued guidance on network adequacy standards, but enforcement remains inconsistent. A 2023 Government Accountability Office (GAO) report found that half of the major insurers reviewed had network adequacy deficiencies in at least one specialty or region.

The No Surprises Act was supposed to fix this imbalance by giving OON physicians access to IDR. But if physicians don't know they're being underpaid—or don't have the resources to pursue IDR—the thin-network strategy continues to profit the insurer.

Administrative Burden: Winning by Exhaustion

If the delay-and-deny tactic is about hoping physicians won't appeal, the administrative burden tactic is about making sure they can't. Insurance companies have invested billions in building complex, labyrinthine appeals processes that are specifically designed to consume physician time and resources.

Consider what it takes to appeal a single underpaid claim: identify the specific denial reason (often buried in coded EOB language), gather supporting clinical documentation, write an appeal letter citing relevant policy language, submit through the insurer's proprietary portal (each payer has a different one), track the appeal timeline, respond to requests for additional information, and follow up when deadlines are missed—by the insurer, not the physician.

Insurers compound this burden with deliberately short appeal deadlines. Many payers require appeals within 60 to 90 days of the initial denial—a timeline that sounds reasonable until you consider that the denial notification itself may arrive 45 days after submission, leaving a practice just weeks to respond. Miss the deadline by a day, and the denial becomes final.

Proprietary portals add another layer of friction. Each insurer requires physicians to submit appeals through its own system, with its own login credentials, document formatting requirements, and attachment limitations. A practice working with five major payers must maintain fluency in five different appeal platforms. Some portals have known technical issues—submission failures, lost documents, reset timers—that further disadvantage physicians.

Intimidation and Misinformation: The Psychological Game

The final tactic in the insurer's playbook is perhaps the most troubling: using fear, uncertainty, and misinformation to discourage physicians from pursuing legitimate payment disputes. This tactic exploits the power imbalance between individual physicians and billion-dollar insurance corporations.

Common intimidation tactics include:

• Threatening credentialing consequences. Insurers may imply that pursuing payment disputes could affect a physician's network standing or future credentialing—even though this is prohibited under the No Surprises Act and most state laws.
• Implying legal risk. Some payers send "compliance" letters suggesting that the physician's billing practices may be under review, creating anxiety that discourages further dispute activity.
• Misleading Explanation of Benefits (EOBs). EOBs are often designed to be confusing, using insurer-specific codes and jargon that obscure the actual underpayment. A physician may see "allowed amount: $1,200" and "patient responsibility: $0" and assume the claim was paid fairly—without realizing that the billed amount of $3,800 was reduced by $2,600.
• "Take it or leave it" settlement offers. Insurers may offer a slightly increased payment in exchange for the physician waiving rights to further dispute—an offer that sounds generous but typically represents only 20% to 30% of the actual underpayment.

A 2024 survey by the Physicians Foundation found that 38% of physicians reported feeling "intimidated" by at least one insurance company's response to a billing dispute. Among those who chose not to appeal an underpayment, 22% cited fear of retaliation as a primary reason.
