Matrix Medical Network Sent Nurses to Patients' Homes. Regulators Say the Diagnoses They Recorded Weren't Supported.

A nurse visits a Medicare Advantage patient at home and records a list of health conditions. Regulators say some of what got recorded didn't hold up — and it was submitted anyway, because more diagnoses meant a bigger payment.

Community Care Health Network LLC, doing business as Matrix Medical Network, along with DPN USA, doing business as HealthFair, and HealthFair's founder Shahriah "James" Ekbatani, have agreed to pay a combined $56.5 million to resolve allegations that they submitted unsupported diagnosis codes to inflate Medicare Advantage payments.DOCUMENTED

The settlement addresses the risk-adjustment mechanism at the center of the Medicare Advantage program, in which insurers are paid more for enrollees with a documented history of specific health conditions — creating a direct financial incentive to record as many qualifying diagnoses as possible.DOCUMENTED

Key facts
  • Matrix Medical Network, HealthFair, and founder Shahriah Ekbatani agreed to pay a combined $56.5 million.
  • Both companies conducted in-home health assessments for Medicare Advantage Organizations, evaluating patients and reporting diagnosis codes used to calculate federal payments.
  • The government alleges Matrix reported diagnoses despite insufficient supporting information from its in-home assessments.
  • Medicare Advantage plans are paid more for patients with documented chronic conditions, creating a direct incentive tied to diagnosis volume.
  • The case was handled jointly by DOJ's Civil Division, the Southern District of New York, and the Eastern District of Texas.

How in-home risk-adjustment assessments work

Medicare Advantage, also known as Medicare Part C, allows beneficiaries to enroll in private health plans administered by Medicare Advantage Organizations, which contract with the Centers for Medicare and Medicaid Services to provide coverage in exchange for capitated, per-patient payments.DOCUMENTED CMS adjusts those payments based on each beneficiary's documented health status, using diagnosis codes the insurer submits — meaning a patient recorded with more, or more severe, chronic conditions generates a larger payment to the insurer managing their care.DOCUMENTED

To gather the diagnosis information that drives these payments, Medicare Advantage Organizations frequently contract with companies like Matrix and HealthFair to send nurses or other health professionals directly to a patient's home for an assessment, rather than relying solely on diagnoses recorded during a patient's regular visits to their own physician.REVIEWED These in-home visits are separate from a beneficiary's ongoing medical care, existing primarily to identify diagnosis codes that support the payment calculation.REVIEWED

What the government alleges went wrong

According to the government, Matrix reported diagnosis codes to Medicare Advantage Organizations based on its in-home assessments even in instances where the underlying assessment did not contain sufficient information to actually support the diagnosis being reported.DOCUMENTED Because those Medicare Advantage Organizations in turn submitted the diagnoses to CMS to calculate their own risk-adjusted payments, an unsupported diagnosis recorded during a Matrix or HealthFair home visit could translate directly into an inflated payment from the federal government — without any independent check verifying that the diagnosis reflected the patient's actual documented health status.REVIEWED

An in-home visit exists specifically to identify diagnosis codes that drive a federal payment calculation — a structure that, according to the government, produced diagnoses the underlying assessments didn't actually support.

Why home-assessment companies sit at a particular pressure point

Unlike a beneficiary's own treating physician, who has an ongoing clinical relationship and a broader medical record to draw on, a company conducting a single in-home assessment is evaluated in part on how many qualifying diagnoses its visits produce — creating a structural incentive that can push toward recording marginal or unsupported diagnoses when a stricter reading of the assessment might not have supported them.REVIEWED That dynamic has made in-home risk-adjustment assessment companies a recurring focus of Medicare Advantage fraud enforcement, since the diagnoses they generate function as inputs to a payment formula rather than as part of a patient's ongoing course of treatment.REVIEWED

Officials' statements

The Justice Department framed the settlement as consistent with its broader emphasis on combating health care fraud, noting that the False Claims Act remains one of its most effective tools for recovering funds improperly obtained from federal health programs.REVIEWED The matter was handled by Trial Attorney Samson Asiyanbi of the Civil Division, Assistant U.S. Attorneys Rachael Doud and Ilan Stein of the Southern District of New York, and Assistant U.S. Attorney Kevin McClendon of the Eastern District of Texas.DOCUMENTED

As with other False Claims Act settlements, the claims resolved by this agreement are allegations only, and there has been no determination of liability against Matrix, HealthFair, or Ekbatani.DOCUMENTED Individual settlement agreements were reached separately with Matrix Medical Network, HealthFair, and Ekbatani himself, reflecting each party's distinct role in the underlying conduct.DOCUMENTED

Why risk-adjustment cases keep recurring across Medicare Advantage

Matrix and HealthFair's settlement joins a growing list of False Claims Act cases targeting the risk-adjustment mechanism at the core of Medicare Advantage, reflecting a program structure where payment size is directly tied to the volume and severity of diagnosis codes on file for each beneficiary.REVIEWED Because CMS depends on Medicare Advantage Organizations, and the vendors those organizations hire to conduct assessments, to accurately and honestly report diagnosis information, the entire payment system rests on a degree of self-reporting that has repeatedly proven vulnerable to exactly the kind of unsupported-diagnosis pattern alleged in this case.REVIEWED

For beneficiaries who have participated in an in-home health assessment through their Medicare Advantage plan, the visit itself typically produces no direct treatment and exists primarily to document diagnosis information for the insurer's payment calculation — a distinction worth understanding, since a home assessment is not a substitute for regular care from a treating physician, regardless of how many diagnoses it generates on paper.REVIEWED

The joint handling of the case across the Civil Division and two separate U.S. Attorney's Offices reflects how Medicare Advantage fraud investigations often span multiple jurisdictions, since a national in-home assessment company can generate the underlying conduct across dozens of states while the insurers receiving the resulting diagnosis codes may be headquartered in an entirely different region. Coordinating a single settlement across those jurisdictions, rather than pursuing separate regional cases, allows the government to resolve the full scope of a company's alleged conduct in one comprehensive agreement, rather than leaving related allegations to be litigated piecemeal across multiple courts over an extended period.REVIEWED
