Hospital Billing Fraud: When the Record Can’t Support the Bill

Hospital billing fraud begins when a hospital knowingly bills for care its records cannot support, inflates the payment classification or misrepresents the conditions that make a claim payable. Medicare and other government health care programs pay those bills with taxpayer money. The decision can sit in an admission policy, a diagnosis query, a software rule or the finance department’s charge table. If you work where that decision becomes a bill, you may know something an auditor looking at the final code will never see.

What Is a Red Flag in Medical Billing?

A repeated mismatch between the clinical record and the bill is a red flag in medical billing, especially when a hospital policy or software rule produces it. This form of hospital fraud can begin before anyone submits a claim.

UCHealth agreed to pay $23 million in 2024 over an alleged emergency department facility coding rule. According to the Justice Department’s account, the alleged rule used the count of vital-sign checks relative to hours in the department to select the highest facility level, regardless of the patient’s condition or the resources used.

Checking the code against the claim only follows the last step. The earlier question is why the system chose that code for that visit.

What Are Some Examples of Billing Fraud?

Hospital billing fraud includes unsupported admissions, inflated diagnoses or service levels, services never provided, duplicate bills and claims that fail coverage or provider requirements. Each leaves a different trail.

Calling all of this upcoding hides the differences. Tenet‘s civil settlement in 2006 included allegations that it billed for services and supplies patients never received. United Memorial Medical Center‘s 2023 settlement included allegations that it billed a federal program for COVID-19 tests also billed to Texas or Houston. One concerns whether the service happened. The other concerns who already received a bill for it.

Unbundling separates services that the payment rules put together. Under the Centers for Medicare & Medicaid Services’ payment-window policy, outpatient tests and other admission-related care within the payment window belong on the inpatient bill. This includes services from the hospital and from an entity it wholly owns or operates. The service date and the entity billing it matter alongside the code.

Hospital Admission Fraud Starts With the Wrong Status

Alleged hospital admission fraud across 119 Community Health Systems hospitals accounted for $89.15 million of a 2014 settlement of $98.15 million. The Justice Department described a corporate effort to increase inpatient admissions from 2005 through 2010 for patients whose care, the government alleged, belonged in less costly outpatient or observation settings. The affected programs included Medicare, Medicaid and TRICARE.

The care could have happened exactly as documented. The alleged falsehood was the hospital’s claim that it needed to happen as an inpatient stay.

Hours are a separate question. Banner Health agreed to a 2018 settlement that included allegations of inflated observation hours.

Because one secondary diagnosis the record does not support can move an inpatient stay into a higher-paying group, the documentation query matters as much as the final diagnosis list in DRG upcoding.

Prime Healthcare resolved allegations of falsified diagnosis information, including complications and comorbidities, in a 2018 settlement. The settlement covered admission allegations as well as upcoding.

Oroville Hospital reached a 2024 settlement over alleged false systemic inflammatory response syndrome codes, unnecessary admissions and bonuses based on how many patients physicians admitted. The code is only part of that story. The alleged hospital kickbacks put a financial incentive inside the admission decision itself. The physician compensation formula and the resulting claims belong in the same conversation.

A Real Procedure Can Fail Medicare’s Coverage Conditions

A procedure’s setting or timing can leave a hospital billing for care outside Medicare’s coverage conditions. The kyphoplasty settlements reached more than 130 hospitals and approximately $105 million by the time of the Justice Department’s December 2015 kyphoplasty announcement. The Justice Department alleged that hospitals billed this spinal-fracture treatment as inpatient care when outpatient treatment was appropriate. Medtronic Spine separately settled allegations that its predecessor, Kyphon, had counseled hospitals to use inpatient billing.

The cardiac-device coverage review reached 457 hospitals in the settlements announced in October 2015. The government alleged that hospitals implanted defibrillators during Medicare’s restricted waiting periods from 2003 through 2010: 40 days after a heart attack, or 90 days after bypass surgery or angioplasty. Those waiting periods gave the heart time to recover enough that a device might no longer be necessary.

The operative report can show that a procedure happened. Its setting and the patient’s preceding treatment can explain why Medicare should not have paid for it.

Hospital Outlier Payments Run on Charges

Hospital outlier payments provide extra reimbursement for unusually costly care. The calculation uses current charges and a cost-to-charge ratio derived from an earlier cost report. Raising the price list can therefore raise the estimated cost used for payment before the ratio catches up.

St. Vincent Hospital admitted that in 2018 and 2019 it raised inpatient charges once by 18% and twice by 15%. Those increases generated outlier payments even where patients had no unforeseen complications or extended stays to explain extraordinary costs. The hospital agreed to pay approximately $1.784 million in 2022 and admitted receiving payments it was not entitled to. Even its voluntary repayment had left Medicare short.

In Silver Lake Hospital‘s 2024 settlement, the government alleged that charges rose far faster than costs, and beyond what the hospital could repay when Medicare reconciled its cost reports. A diagnosis review cannot find a defect in those financial inputs.

The Right Service Can Have the Wrong Provider

Hospital billing can depend on who provided or supervised the care. The Department of Health and Human Services’ Office of Inspector General has reached settlements over missing supervision, provider enrollment and excluded personnel.

Froedtert Memorial Lutheran Hospital settled allegations that nurses provided wound care without the required supervision. Children’s Hospital of Orange County settled allegations involving nurse-practitioner encounters without corresponding services from a properly enrolled provider. Ascension Providence Rochester Hospital settled allegations that it employed someone excluded from federal health care programs.

The People Who See the Pattern

A whistleblower does not have to work for the hospital that sent the bills. The kyphoplasty cases came from former reimbursement and regional sales managers at the device manufacturer. A cardiac nurse and a health care reimbursement consultant brought the defibrillator case. Their work connected them to a billing practice that crossed hospital boundaries.

The Community Health Systems whistleblowers included nurses, a coder, physicians, a health-information director, an emergency-services coordinator and a case-management supervisor. Healthcare finance and contracting staff can see charge changes and physician-payment formulas. Clinical and coding staff can see how a query, an admission target or a software setting changes the claim.

The evidence a whistleblower needs connects the care, the claim and the decision that made them diverge. A diagnosis query, a software setting or an internal warning can show both the mismatch and who knew about it. Our whistleblower experts work through that connection with you, including your own role in applying the billing rule or raising it internally.

A high-severity billing pattern points toward records that need closer review. RAND’s 2024 Methodologies to Measure Upcoding in Provider Settings found that few studies checked coding patterns against an independent standard: just three of them tested coding against a gold standard, while the others relied on indirect measures of coding intensity.

The 1999 Journal of AHIMA article Honest Mistake or Fraud? Meeting the Coding Compliance Challenge makes the operational point: computerized checks identify potential problems, while a health-information professional reviews the chart before changing the coding. An audit trail also shows the correction and what happened next.

A whistleblower can bring a qui tam case under the False Claims Act over hospital billing fraud involving knowingly false claims to government health care programs. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. In the cardiac-device settlements, the Justice Department reported that the whistleblowers received more than $38 million.
