Emergency Department Facility Upcoding: When an Automatic Rule Picks the Highest Level

Emergency department facility upcoding is billing a higher hospital service level for an emergency visit than the resources used to treat the patient support. In this form of hospital billing fraud, an automatic coding rule inflates the charge across many visits. The software can do exactly what it was told and still produce the wrong bill.

Facility Level Versus Professional ED Upcoding

Facility-level upcoding concerns the hospital’s bill for the resources used during an emergency visit. Professional ED upcoding concerns the clinician’s services. The hospital’s facility payment and the physician’s professional payment cover different parts of the same health care encounter. That makes the hospital’s resource records central to understanding its facility level. The physician’s account of the visit does not, on its own, explain how the hospital selected that level.

While ED facility levels concern outpatient care, inpatient diagnosis-related group upcoding changes the payment classification for an admitted patient’s stay through unsupported diagnosis information. For an ED facility case, the central comparison is the level the hospital billed against the resources the emergency visit used.

What the Hospital’s Facility Code Has to Represent

A hospital’s ED coding method has to connect the level it selects to the intensity of hospital resources used. The Centers for Medicare & Medicaid Services made that requirement explicit in its January 2008 visit-code guidance. The guidance also requires the services to be medically necessary and documented. A hospital’s own method still has to answer to the care it delivered.

The guidance identifies 99281 through 99285 as the visit codes for Type A emergency departments and G0380 through G0384 for Type B departments. CMS allows hospitals to use different staffing arrangements, including nurses and pharmacists.

CMS draws another useful line: contact with hospital staff or time in a room for another service does not, by itself, justify adding a visit code. The additional visit must represent a distinct service. Counting something that happened in the department is only useful if the count supports the service being billed.

CPT 99285 and the Vital-Sign Rule

The UCHealth upcoding settlement resolved a whistleblower case over an emergency department software rule. The government announced the $23 million settlement in November 2024, and the whistleblower received $3.91 million.

ED facility code 99285 was the highest of five levels at issue. The Justice Department alleged that the system assigned that code when the number of vital-sign checks exceeded the hours the patient spent in the department.

The allegations covered certain visits billed to Medicare and TRICARE from November 2017 through March 2021. The rule excluded visits shorter than an hour. According to the government’s account, it selected the top code regardless of the patient’s condition or the hospital resources used for treatment. The government also alleged that UCHealth knew the rule failed the programs’ billing requirements because it did not adequately reflect those resources.

A count can accurately record how often staff checked a patient while the rule using that count overstates the service the hospital provided. That is what makes this allegation so useful to a billing-system insider. The disputed decision sat in the instruction that converted a clinical event into a facility level. Looking only for a coder who chose the wrong number would miss the policy making the choice.

The Rule Must Connect to Actual Claims

A hospital ED coding algorithm that ignores resource use can repeat the same unsupported level across visits. The evidence connects what the algorithm counted to the encounter records, the facility level submitted and the payment it produced.

Coding policy version history shows which rule applied to a visit. The claims show what the hospital billed, while the medical record shows the care it documented.

An audit that checks only whether the system followed its instructions leaves the instructions themselves unexamined. When the output is automatically the highest emergency facility code, the question is why that rule represents the resources used. For the UCHealth allegation, showing that the vital-sign calculation ran correctly would leave that question unanswered.

An internal objection adds a different question: what did the hospital do after someone raised the mismatch? We work with you to connect the coding rule, its effects and the hospital’s response in a hospital false claims case.

A High-Code Pattern Needs the Patient Record

A high-code pattern points toward encounters worth examining. The patient record is where the billed level meets the care. RAND’s 2024 report, Methodologies to Measure Upcoding in Provider Settings, reviewed 39 studies and found that most examined coding at an aggregate level. Its distinction is unusually sharp: direct measurement, checking coding against a gold standard, appeared in just three of them.

For a facility-code investigation, that means going beyond the percentage of visits assigned the highest level. RAND describes the value of comparing claims with medical-record details, including diagnoses, procedures and screenings. A distribution can show where the hospital’s coding changed. The underlying encounters can show what the higher codes represented.

A separate study, Types of Hospital Frauds: Nature and Methods of Prevention, published in the Journal of Forensic and Investigative Accounting in 2023, examined cases announced by the Justice Department. It concluded that comparing billing records with medical records could have prevented 27 of the 42 fraudulent-billing cases in its sample. Coding-data analysis could have helped prevent 24.

The useful connection is between the two views. Coding analysis finds repeated choices. Medical-record review tests what those choices claimed. The paper also stresses the need for billing expertise and, where necessary, coding and medical specialists. Someone who understands how a hospital turns documented care into a claim can explain a discrepancy that a dashboard merely displays.

Health Management Associates and Inflated Facility Charges

Health Management Associates agreed to pay $12 million for alleged inflation of emergency department facility charges as part of its 2018 civil settlement. The Justice Department’s account described claims to Medicare and Medicaid by certain HMA hospitals from September 2009 through December 2011.

The civil resolution also covered allegations that inpatient services should have been billed as outpatient or observation care. That is the separate problem of hospital admission fraud. The facility-charge component matters here because the level of an emergency visit can be inflated without the allegation turning on whether the hospital admitted the patient.

The Insider Who Can Explain the Coding Policy

The useful knowledge can sit with the person who maintains the rule, the person who reviews its output or the person who received an objection. A billing-system administrator may recognize the configuration and its effective dates. A facility coder or healthcare revenue-cycle analyst may recognize the repeated result. Clinical documentation and compliance staff may understand what the record supports and what management was told.

These are different views of the same billing decision. The hospital insider who can connect them gives the pattern a cause: the instruction that selected the level and the decision to keep using it. The most revealing question may be who approved the rule, rather than who submitted the last claim. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

The Person Who Understands the Rule

If you can explain why your hospital’s software keeps choosing a level the care does not support, speak to one of our whistleblower experts about that rule. We work with you to connect the configuration, the claims and the decisions behind them, and bring in whistleblower lawyers who know hospital coding and reimbursement. We stay with you through the process, working to build your strongest hospital whistleblower case.
