What happened: A Texas worker alleges her insurer created a shadow claim by changing one word in a database entry, hiding a live workers’ comp policy while denying her benefits for 17 months.
Who’s involved: ACE American Insurance Company (Chubb subsidiary), ESIS (claims administrator), CITGO Petroleum Corporation (employer), MediCall/Cognizant, Texas state agencies.
What’s at stake: Approximately $110,000 per year in indemnity benefits allegedly diverted for over 17 months, plus triple damages under civil RICO.
Why it matters: The complaint describes a specific alleged exploit in the TXCOMP workers’ comp database that claims professionals and carrier IT teams will want to understand.
Where it stands: Emergency complaint with TRO motion filed October 15, 2026; no court ruling yet.
"Company" or "Co."? One worker alleges that single abbreviation was enough to split her workers' compensation claim in two - one that paid out behind the scenes, and one that denied her everything.
A former CITGO Petroleum Corporation employee has filed a 59-page emergency complaint in US District Court for the Western District of Texas, alleging that ACE American Insurance Company - a subsidiary of Chubb - and its claims administrator ESIS ran what the filing calls a parallel "dual-claim" operation inside the state's workers' compensation database for more than 17 months.
The complaint was filed on October 15, 2026.
The complaint zeroes in on how the Texas workers' comp database, known as TXCOMP, identifies insurance carriers. Rather than using a fixed federal identification number, the filing says, the system relies on text-based combinations of the claimant's name, employer name, and carrier name. According to the complaint, the defendants took advantage of that design by maintaining two separate carrier entries: "ACE American Insurance Company" on one, and "ACE American Insurance Co." on the other.
The difference between "Company" and "Co." allegedly created two entirely separate data tracks for a single workplace injury, the complaint states. The filing calls the first track (DWC No. 25169058) a "Secret Financial Revenue Engine" - allegedly registered on the backend as a live, approved, and active policy tied to the plaintiff's true identity and an approximately $110,000 annual salary. The second track (DWC No. 25183607), created roughly 35 days later, is described in the filing as an "External Consumer Deflector" - a permanently denied record that blocked the plaintiff from accessing income benefits, medical care, and a prescribed wheelchair.
The employer name was also allegedly split: "CITGO Petroleum Corporation" on one track, "CITGO Petroleum Corp." on the other.
One of the more striking sections of the complaint deals with a $250 physical therapy evaluation. According to the filing, when the plaintiff requested approval for emergency cardiac care, the claims adjuster "issued blanket denials within minutes via informal email channels." But when the $250 evaluation was submitted, the complaint says the adjuster retained MediCall - a medical management arm of Fortune 500 company Cognizant - to conduct a formal utilization review, which is a regulated process where a carrier brings in an outside medical reviewer to approve or deny a treatment request.
The complaint frames this as a telling contradiction. The filing argues that under Texas insurance law, a carrier has no legal basis to order a utilization review on a claim it says is dead and closed. The fact that it did, the complaint says, amounts to "an irrefutable admission by conduct" that the underlying policy was still live.
According to the filing, the plaintiff had already completed roughly 80% of the evaluation when the review kicked in. The complaint says the plaintiff collapsed after trying to lift a 10-pound weight - about the heft of a gallon of milk - during the assessment. Rather than treating the collapse as proof of disability, the filing alleges the insurer used the incident to pressure the clinic into withholding the final evaluation report. That report, the complaint says, was needed to complete a federal disability benefits application.
The complaint lays out a detailed electronic timeline that the filing says reveals the hidden backend activity. According to the complaint, in February and March 2026, independent providers ran billing through the original claim number and received automated confirmations of an active, funded workers' comp policy. The filing alleges these electronic responses returned specific database details including the employer's guarantor ID, the carrier claim number as subscriber ID, and the plaintiff's date of birth - all consistent with a live policy.
On March 13, 2026, the complaint states, the system cleared and approved the plaintiff's prescribed NuMotion custom wheelchair (a TiliteAeroX with Motor SmartDrive). A technician verbally confirmed the approval four days later, according to the filing. The complaint alleges the claims adjuster then manually overrode the system to block delivery.
The filing also alleges that before a high-risk nuclear cardiac stress test, someone swapped the plaintiff's real emergency contact number for an unauthorized phone number in her cardiologist's patient records. The complaint calls this "a lethal mechanism" - arguing that a cardiac emergency during the test would have routed notifications to the wrong person.
The 10-count complaint includes allegations of civil racketeering (RICO), healthcare fraud, computer fraud, and violations of the Texas Labor Code. The filing seeks an emergency court order to reinstate income benefits going back to their start date, delivery of the wheelchair, and triple damages on all diverted funds.
The complaint also says the plaintiff faces losing a home with approximately $670,000 in equity and is currently surviving on $298 per month in food assistance. Two state agencies - TDI-DWC and OIEC - are named as defendants, with the filing alleging they left the plaintiff's medical condition to deteriorate untreated.
If the allegations prove out, the case could sharpen scrutiny on how state workers' compensation databases verify carrier identities - and whether text-based matching creates openings for the kind of parallel-claim scheme described in this filing.
The allegations in the complaint have not been tested, and no court has ruled on the merits.
