Matrix/HealthFair Settlement Shows That Medicare Advantage Risk-Adjustment Vendors Are Still Under Scrutiny

07.23.2026

The Justice Department’s recent Matrix/HealthFair settlement is a reminder that Medicare Advantage fraud enforcement is not limited to insurers. It can reach the vendors, providers, and executives whose work causes Medicare Advantage Organizations to submit unsupported diagnosis codes to CMS.

DOJ announced that Community Care Health Network LLC, doing business as Matrix Medical Network, DPN USA, doing business as HealthFair, and HealthFair founder Shahriah “James” Ekbatani agreed to pay $56.5 million to resolve False Claims Act allegations. DOJ stated that Matrix will pay $36.5 million, HealthFair will pay $5 million, and Ekbatani will pay $15 million. HHS-OIG entered into a five-year Corporate Integrity Agreement with Matrix.

Risk-adjustment allegations can be technical, but the core theory is simple. Medicare Advantage plans receive higher payments when beneficiaries are coded as having certain serious conditions. DOJ alleged Matrix caused plans to submit false or invalid diagnoses based on in-home assessments, even though the diagnoses lacked sufficient support, did not conform to CMS coding guidelines, or were not diagnosed by other providers in nearby years.

DOJ also alleged that HealthFair reported unsupported diagnoses from mobile health assessments, including diagnoses of serious conditions without confirming documentation, and other diagnoses based solely on patient attestation, claims history, past medical history, or medication. That is why Medicare Advantage risk adjustment fraud can be so fact-intensive: the issue is often whether a diagnosis code submitted to CMS was adequately documented and clinically valid.

Because these coding decisions may be made through downstream vendors, the best evidence sometimes sits outside the insurer. In-home assessment companies, mobile-screening businesses, chart-review vendors, coders, clinicians, and sales employees may see pressure to identify diagnoses that increase payments rather than reflect documented conditions.

The whistleblower component is significant. The Matrix settlement resolves qui tam claims by Nancy Cahill, a former Matrix employee, who will receive $7.3 million. The HealthFair and Ekbatani settlements resolve claims by Robert Oristaglio, D.O., HealthFair’s former chief medical officer, who will receive $3.6 million.

Whistleblower Partners has written extensively about healthcare fraud and represented whistleblowers in major Medicare Advantage matters, including the firm’s $581 million Kaiser Permanente settlement. Matrix/HealthFair demonstrates that DOJ continues to scrutinize the full ecosystem around Medicare Advantage coding, including insurers and vendors. For insiders, the enforcement message is clear: unsupported diagnosis codes can be false claims when they cause CMS to pay more than Medicare owes.
