Medicare Advantage Diagnosis Code Inflation False Claims Act

How Medicare Advantage Diagnosis Code Inflation Became a $541.5 Million False Claims Act Case

The Villages Health System LLC (TVH) agreed to a $541.5 million settlement to resolve allegations that it violated the False Claims Act by submitting false diagnosis codes to inflate payments from the Medicare Advantage program — one of the largest Medicare Advantage diagnosis code inflation False Claims Act resolutions on record. The settlement, announced in August 2026, covers alleged conduct from 2020 through 2024 and sends a clear enforcement signal to provider groups operating under Medicare Advantage risk-sharing arrangements. Every False Claims Act matter is different; results depend on the specific facts of each case, and no similar outcome is implied.

This post explains how the Medicare Advantage payment structure creates the conditions for diagnosis code inflation, what TVH is alleged to have done, why self-disclosure did not eliminate liability, and what insiders at similar organizations should understand about the False Claims Act’s qui tam mechanism.

How Medicare Advantage Risk Adjustment Creates Fraud Opportunity

Under the Medicare Advantage program, also known as Medicare Part C, the Centers for Medicare & Medicaid Services pays Medicare Advantage Organizations (MAOs) a fixed monthly capitated amount per enrolled beneficiary, adjusted upward for sicker patients expected to incur higher healthcare costs. CMS collects medical diagnosis codes from MAOs to calculate those risk adjustments. The diagnoses must be supported by the medical record from a face-to-face visit between a patient and a provider, and for outpatient visits, must have required or affected patient care, treatment, or management at the visit.

The downstream payment chain matters. At times, MAOs agree to pay provider groups like TVH a set percentage of what the MAO receives from CMS. Under such arrangements, provider groups receive more reimbursement for sicker beneficiaries and less for healthier ones. That structure creates a direct financial incentive to submit diagnosis codes that make patients appear sicker than their records support.

In the TVH matter, the three MAOs involved were Humana Inc.; UnitedHealthcare (including UnitedHealthcare Insurance Company, United Healthcare of Florida Inc., Preferred Care Partners Inc., and Care Improvement Plus South Central Insurance Company, Inc.); and GuideWell Mutual Holding Corporation (Blue Cross and Blue Shield of Florida Inc. and Florida Blue Medicare Inc.).

What TVH Actually Did: The Mechanics of the Alleged Fraud

The settlement resolves allegations that, from 2020 through 2024, TVH knowingly submitted false diagnosis codes to MAOs and caused MAOs to submit false diagnosis codes to the Medicare Advantage program, resulting in inflated payments from CMS to MAOs. The diagnosis codes were alleged to be invalid for two reasons: they either did not have adequate support in the patient’s medical record, or they were based on amendments to the medical record that were not initiated by the rendering provider and were not timely or were not approved by the rendering provider.

According to the government, TVH’s knowing submission of those unsupported and undocumented codes caused CMS to make inflated payments to the MAOs, which in turn inflated the MAOs’ payments to TVH.

On December 27, 2024, TVH made a submission pursuant to the HHS-OIG’s Health Care Fraud Self-Disclosure Protocol, disclosing that it had submitted invalid diagnosis codes to multiple MAOs for certain beneficiaries enrolled in their plans. TVH subsequently filed a Chapter 11 bankruptcy petition on July 3, 2025, in the U.S. Bankruptcy Court for the Middle District of Florida (Case No. 6:25-bk-04156-LVV, Bankr. M.D. Fla.). The bankruptcy court approved the settlement on August 25, 2026.

Self-Disclosure Reduced Liability — It Did Not Eliminate It

The United States acknowledged that TVH took significant steps entitling it to credit for cooperating with the government: TVH promptly took remedial actions, self-disclosed the invalid diagnoses to HHS-OIG, provided a detailed and thorough written disclosure, and cooperated throughout the investigation. Despite that credit, a $541.5 million settlement still resulted. As Acting Deputy Inspector General for Investigations Miranda L. Bennett of HHS-OIG stated: “The provider’s use of the OIG Self Disclosure Protocol and its cooperation were important factors in resolving this matter.” Every False Claims Act matter is different; results depend on the specific facts of each case, and no similar outcome is implied.

Self-disclosure, in other words, is a factor that may reduce liability — it is not a shield against False Claims Act liability. The MAOs are separately returning overpayments they received as a result of TVH’s conduct by deleting invalid codes and by entering into agreements with the Department of Justice and CMS to return the funds.

For employees who work inside organizations with similar Medicare Advantage risk-sharing arrangements, this outcome raises a practical question: if the provider self-discloses, what options remain for an insider who observed the conduct?

What Whistleblowers and Qui Tam Relators Should Know About These Cases

Under 31 U.S.C. § 3730, a person may bring a civil action for a violation of section 3729 for the person and for the United States Government. This qui tam mechanism allows insiders — physicians, coders, compliance officers, billing staff — to file suit on the government’s behalf and receive a portion of any recovery. In cases where the government intervenes, the relator may receive at least 15 percent but not more than 25 percent of the proceeds; in cases the government declines to intervene, the relator may receive not less than 25 percent and not more than 30 percent.

A recent parallel case illustrates how the whistleblower path works in practice. Monogram Health Professional Services PC and Monogram Health Inc. agreed to pay $2.4 million to resolve allegations that they violated the False Claims Act by causing the submission of false diagnosis codes to increase payments from the Medicare Advantage program. The civil settlement included the resolution of claims brought under the qui tam provisions of the False Claims Act by Dr. Ajay Gupta, a physician formerly employed by Monogram. Dr. Gupta received approximately $380,000 as his share of the recovery. The Monogram case involved allegations that false HCC codes — including codes for Protein-Calorie Malnutrition, Substance Use Disorder, Coagulation Defects and Other Specified Hematological Disorders, and Angina Pectoris — were submitted without adequate clinical support, the same core legal theory at issue in the TVH matter. Every False Claims Act matter is different; results depend on the specific facts of each case, and no similar outcome is implied.

Clinicians and other insiders who observe diagnosis codes being added without adequate clinical documentation, or medical record amendments being made without the rendering provider’s knowledge or approval, may have actionable information. For a broader overview of how hospital billing fraud under the False Claims Act is pursued through the qui tam process, including the procedural steps from filing under seal through potential recovery, our practice area page provides additional context.

One procedural rule deserves particular attention. Under 31 U.S.C. § 3730(b)(5), when a person brings a qui tam action, no person other than the Government may intervene or bring a related action based on the facts underlying the pending action. This first-to-file rule means that a later-filed suit based on the same underlying facts may be barred. Anyone who believes they have observed Medicare Advantage diagnosis code inflation should consult with qui tam counsel before approaching the government directly.

Frequently Asked Questions

What is Medicare Advantage diagnosis code inflation and why does it violate the False Claims Act?

Medicare Advantage diagnosis code inflation occurs when a provider submits diagnosis codes to MAOs that lack adequate support in the patient’s medical record, or that are based on record amendments not initiated by, not timely, or not approved by the rendering provider — causing CMS to make inflated capitated payments. Under 31 U.S.C. § 3729, knowingly presenting or causing to be presented a false or fraudulent claim for payment to the United States may give rise to False Claims Act liability, including treble damages and per-claim civil penalties.

Does self-disclosing to HHS-OIG protect a provider from a False Claims Act settlement?

Self-disclosure under the HHS-OIG Health Care Fraud Self-Disclosure Protocol may result in cooperation credit that reduces a settlement amount, but it does not eliminate False Claims Act liability — TVH received cooperation credit and still agreed to a $541.5 million settlement. As Assistant Attorney General Brett A. Shumate stated: “We will hold accountable entities that inflate payments through invalid diagnoses; at the same time, we will continue to credit organizations that disclose wrongdoing, take appropriate remedial actions, and fully cooperate with the government’s investigation.” Every False Claims Act matter is different; results depend on the specific facts of each case, and no similar outcome is implied.

How much could a whistleblower receive in a Medicare Advantage diagnosis code inflation case?

Under 31 U.S.C. § 3730(d), a qui tam relator in a government-intervened case may receive at least 15 percent but not more than 25 percent of the proceeds; in a case the government declines, the relator may receive not less than 25 percent and not more than 30 percent. In the Monogram Health matter, Dr. Ajay Gupta, a physician formerly employed by Monogram, received approximately $380,000 as his share of a $2.4 million recovery after filing a qui tam lawsuit alleging the same Medicare Advantage risk-adjustment fraud theory. Every False Claims Act matter is different; results depend on the specific facts of each case, and no similar outcome is implied.
