Attorney General William Tong and federal prosecutors have secured a $145,720 settlement from a Branford medical laboratory and its owner after she concealed key relationships from Connecticut Medicaid in order to obtain enrollment her lab would not otherwise have qualified for.

Tricia Conroy owned and operated Coastal Diagnostics, LLC (Coastal), a reference laboratory in Branford. When applying for Medicaid enrollment, Conroy did not disclose that her husband, Paul Conroy, owned a related Branford lab, Genco Lab, LLC (Genco), and that she served as Genco's Chief Operating Officer. The undisclosed relationships would have disqualified Coastal from enrollment entirely. Genco was under a payment suspension and fraud investigation at the time of Coastal's application, and Connecticut Medicaid's rules would have blocked approval had the connections been accurately reported.

Coastal submitted claims for laboratory services before Connecticut Medicaid identified the connection between the two labs and terminated Coastal's provider agreement. The $145,720 settlement covers claims submitted between March 6 and June 3, 2024.

The case extends a pattern of enforcement involving the same Branford address. In August 2025, Genco and its owners paid $1,255,825 to settle allegations that they billed government health care programs for medically unnecessary urine drug tests.

"Healthcare providers who participate in taxpayer funded healthcare plans have an obligation to provide accurate and truthful information to the government," said Attorney General Tong. "My office stands ready, with our federal and state partners, to take strong action to protect the integrity of our healthcare programs."

Tong announced the settlement alongside U.S. Attorney for the District of Connecticut David X. Sullivan. Coastal has been terminated from the Connecticut Medicaid program.
