Medicare Advantage Provider Group Risk Adjustment Fraud: The Plan Gets the Code, the Provider Shares the Money

Medicare Advantage provider group risk adjustment fraud can begin inside a medical practice and reach Medicare through several insurers. The group sends diagnoses to the plans, the plans use them to obtain risk-adjusted payments, and a provider contract can send a share of the increase back to the group. If you know who chose the codes, instructed the physicians or stopped a correction, you may know how that money was generated.

The Provider’s Contract Connects the Chart to the Money

A provider group can supply the information that increases Medicare’s payment while receiving its own money from an insurer. That makes the provider’s decisions part of a Medicare Advantage fraud inquiry even when the government pays the plan.

The Centers for Medicare & Medicaid Services pays Medicare Advantage organizations a monthly amount for each enrolled beneficiary. Diagnoses help determine the risk score used to adjust that amount. The payment path runs from the medical record through coding and plan submission to Medicare. A provider may treat the patient, collect the diagnoses and send them to the plan. The insurer then submits the codes that affect its reimbursement. When false diagnoses inflate those payments, taxpayers fund conditions the patients do not have.

The provider’s financial incentive sits in its contract. When the agreement pays a percentage of the plan’s Medicare revenue, a higher risk-adjusted payment can increase the provider’s compensation too. The Justice Department describes that arrangement in its provider settlements, including those involving HealthCare Partners, Sutter Health and The Villages Health System.

The contract explains why the provider wanted the additional diagnosis. The visit note, coding instructions and response to a rejected diagnosis explain how the organization pursued it.

Different Provider Structures, Different Decisions

The provider cases reach physician associations, affiliated medical groups, management companies and businesses delivering care in patients’ homes. Each structure puts different people between the clinical encounter and the plan’s submission.

HealthCare Partners’ Coding Program Traveled Through a Medical Services Organization

HealthCare Partners’ case involved both coding guidance and a review process that allegedly favored additions. In its October 2018 settlement announcement, the Justice Department said DaVita operated a medical services organization that contracted with Medicare Advantage organizations and received a share of their Medicare payments. HealthCare Partners was a California independent physician association acquired by DaVita.

DaVita disclosed practices instituted by HealthCare Partners, including improper guidance directing physicians to use a higher-paying code for a spinal condition. The $270 million settlement also resolved whistleblower allegations of one-way chart review. HealthCare Partners allegedly searched for missed diagnoses and sent additions to plans while ignoring inaccurate codes that should have been deleted.

The alleged program gave favorable findings a route to the insurer and left unfavorable findings behind. An insider who saw the review instructions could explain that selection before anyone examined the plan’s final submission.

Sutter’s Provider Affiliates Shared in Plan Payments

Sutter Health contracted to care for Medicare Advantage beneficiaries in California and received part of the plans’ payments. Its August 2021 settlement required $90 million, less than HealthCare Partners’ settlement, to resolve allegations involving unsupported diagnoses and inadequate correction after Sutter learned of them.

The government alleged that Sutter’s codes inflated payments to both the plans and Sutter. It also alleged that Sutter failed to take sufficient action to identify and delete additional unsupported codes after becoming aware of the problem. The second allegation reaches beyond the person who entered a diagnosis. It concerns what the provider organization did with knowledge that its coding needed correction.

Complete Health’s Management Company Prompted the Physicians

Complete Health manages, owns or operates affiliated provider groups. Its contracts paid it a percentage of the Medicare payments received by the plans. The Justice Department’s August 2026 announcement describes how the alleged coding process worked inside that management structure.

The government contended that Complete Health distributed incorrect coding guidance about drug and alcohol dependence and certain psychiatric conditions. According to that account, coders identified additional diagnoses and Complete Health prompted doctors to add them despite a lack of clinical support. The doctors allegedly added the codes, increasing Medicare payments to the plans and the share passed to Complete Health.

The physician’s entry was the last clinical step in a process that allegedly began with management guidance and a coder’s review. The person who signed the chart and the people who caused the diagnosis to appear had different roles.

Monogram’s Home Care Carried a Risk-Sharing Incentive

Monogram Health provides in-home care and related services under contracts with Medicare Advantage organizations. Its agreements made it eligible for higher payments when the beneficiaries in its care had higher risk scores. Its August 2026 settlement resolved allegations about clinically inaccurate or unsupported diagnoses, or diagnoses that did not require or affect care, treatment or management.

The Justice Department explains the clinical requirement in that announcement: diagnoses must have support in the record of a face-to-face visit. For outpatient visits, the condition must have required or affected care, treatment or management at that visit.

The Villages Sent the Codes to Several Insurers

The Villages Health System offers a particularly clear view of a provider group working across plans. Its $541.5 million settlement, larger than either the HealthCare Partners or Sutter settlement, resolved allegations that it knowingly sent false diagnosis codes to Medicare Advantage organizations, which submitted them to Medicare and received inflated payments. The government alleged that the provider’s payments rose with them.

The government alleged that the codes lacked adequate medical-record support or rested on amendments that the treating provider had not initiated and that were untimely or unapproved. Those record amendments are an operational detail an insider can recognize: who requested the change, when it entered the chart and whether the clinician approved it.

The Villages disclosed the invalid codes itself. The Justice Department named three recipient organizations: Humana, UnitedHealthcare and GuideWell. Its August 2026 announcement said those organizations were returning overpayments by deleting invalid codes, entering repayment agreements, or both.

One provider’s coding practices therefore reached several insurers’ payment submissions. The provider’s settlement and the plans’ return of overpayments addressed different parts of that path. A correction inside the practice had to connect to the data and money outside it.

A Coding Vendor Can Reach Across Plans Too

A vendor can supply both the suggested diagnosis and the pressure to put it into the record. DxID was a wholly owned subsidiary of Independent Health Corporation. The government’s complaint alleged that Independent Health created the vendor to search medical records and query physicians for additional diagnoses, serving its own plans and other insurers.

The complaint alleged that DxID staff visited physicians’ offices, checked diagnoses on forms and presented the completed forms for signature. It also quoted the vendor offering services for a percentage of additional recoveries. That contingent compensation tied the vendor’s pay to the revenue its work produced.

The complaint also alleged that DxID drew diagnoses from problem lists and lab results that a health care provider might never have reviewed. It described an alcohol-dependence code drawn from an old medical-history entry even though the condition was marked resolved. A past condition had become a current source of payment.

Meeting notes quoted in the complaint expose a further separation between the signed form and the clinical record: doctors were signing DxID’s addendums without updating the diagnosis list in the medical record.

The allegation puts the form, the chart and the vendor’s output beside each other. A physician’s signature could enter the coding process while the diagnosis list used in the practice stayed as it was.

An assessment vendor can generate the record itself: the government alleged in its June 2026 Matrix Medical Network settlement announcement that invalid diagnoses from contracted in-home assessments reached plans and inflated their payments.

A Plan’s Question Can Change the Evidence

Seoul Medical Group’s case shows what happened after a plan challenged a provider’s coding. The Justice Department alleged that Seoul submitted spinal enthesopathy and sacroiliitis diagnoses for patients who did not have those conditions. When a plan questioned the spinal enthesopathy coding, Seoul allegedly enlisted Renaissance Imaging Medical Associates to create radiology reports that appeared to support it.

The government alleged that the plan passed a portion of the increased Medicare payment to Seoul. In that account, a plan’s question prompted the creation of supporting radiology reports for diagnoses patients did not have.

A whistleblower who knows that sequence can explain why a supporting report appeared.

The Correction Has to Reach the Payment Data

A correction can stop inside a provider’s own systems. In the Sutter whistleblower’s account, auditors received instructions to change the billing side of the electronic record while only physicians could correct the clinical encounter. The complaint alleged that management was told a billing-file correction would leave inaccurate codes in the data sent to Medicare.

That split between billing and clinical corrections gives a precise question to the person who saw the work: which record changed, and which record continued to supply the diagnosis? The later government settlement allegations focused on Sutter’s failure to identify and delete additional unsupported codes after learning of them.

The Villages announcement describes correction at the other end of the chain, where the insurers were returning overpayments through code deletions or repayment agreements. Together, the accounts show why the provider’s internal correction and the plan’s payment submission belong in the same inquiry. The staff member who found the error, the clinician allowed to amend the encounter and the organization submitting to Medicare may each control a different part.

Ownership Changes Who Can Influence the Coding

Ownership and payment arrangements can give a company more influence over the people recording diagnoses. The American Institutes for Research’s 2026 report, Medicare Advantage Fraud, Waste, and Abuse Policy Options, describes coding protocols, electronic prompts and retrospective reviews as ways integrated organizations can exercise that influence.

It also explains sub-capitation, in which a plan pays a provider group upfront and the group pays its physicians on a capitated basis. Its description of the percentage-of-premium arrangement makes the incentive plain: as coding intensity rises, so does Medicare’s payment to the plan, and the provider’s revenue rises along with it.

The 2015 working paper Upcoding or Selection? Evidence From Medicare on Squishy Risk Adjustment, hosted by Duke Economics, found that coding intensity increased with closer insurer-provider integration. Its explanation matters here: a plan’s ability to influence physicians helps determine how strongly its payment incentive changes coding.

The Medicare Payment Advisory Commission has also described the lack of a systematic public accounting of plan-provider ownership. The contract and the internal operating history can therefore tell an insider more than the brand on the building. In HealthCare Partners’ case, the government identified the physician association’s practices, the acquisition and DaVita’s disclosure separately. What matters is who ran the coding at the time.

What the Provider-Side Insider Can Explain

A coding manager may know where the guidance originated. A physician may know why a requested diagnosis lacked support. Finance may know how a healthcare contract turned additional risk revenue into compensation. An auditor may know why a finding stopped short of the submission. Those views connect the medical record to the organization’s decisions and the payment that followed.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
