Koreatown-Based Medicare Advantage Provider Seoul Medical Group and Related Parties to Pay More Than $62 Million to Settle False Claims Lawsuit

LOS ANGELES – Seoul Medical Group Inc. and its wholly-owned subsidiary Advanced Medical Management Inc., headquartered in the Koreatown area of Los Angeles, have agreed to pay $58.74 million and their former president, Dr. Min Young Cha, has agreed to pay $1.76 million for allegedly violating the False Claims Act by causing the submission of false diagnosis codes for two spinal conditions to increase payments from the Medicare Advantage program.

Renaissance Imaging Medical Associates Inc., a Northridge-based radiology group that worked with Seoul Medical, has also agreed to pay $2.35 million for allegedly conspiring with Seoul Medical Group in connection with the false diagnoses for the two spinal conditions.

“The false claims to Medicare resulted in millions of dollars in losses to the government,” said Acting U.S. Attorney Joseph McNally. “Through this $62.85 million settlement we have recouped those losses and the healthcare providers who made the false claims are paying millions of dollars in additional damages.” 

“Medicare Advantage is a vital program for our seniors and the government expects healthcare providers who participate in the program to provide truthful and accurate information,” said Acting Assistant Attorney General Yaakov M. Roth of the Justice Department’s Civil Division. “Today’s result sends a clear message to the Medicare Advantage community that the United States will zealously pursue appropriate action against those who knowingly submit false claims for taxpayer funds.”

Under Medicare Advantage, also known as the Medicare Part C program, Medicare beneficiaries have the option of enrolling in managed care insurance plans called Medicare Advantage Plans (MA Plans) and the MA Plans contract with healthcare providers, such as Seoul Medical Group, to provide the Medicare-covered benefits. MA Plans are paid a per-person amount to provide the care to their enrollees and, in turn, the MA Plans pay the providers.

The Centers for Medicare and Medicaid Services (CMS), which oversees the Medicare program, adjusts the payments to MA Plans based on demographic information and the health diagnoses of each plan beneficiary. The adjustments are commonly referred to as “risk scores.” In general, a beneficiary with diagnoses that are more expensive to treat will have a higher risk score, and CMS will make a larger risk-adjusted payment to the MA Plan for that beneficiary.

Seoul Medical Group is a healthcare provider that started in 1993 in Los Angeles and has since expanded into at least six states and has contracted at times with a network of 150 independent primary care providers and 1,000 specialists. Dr. Min Young Cha started Seoul Medical Group and until 2023 was its president. 

The United States alleged that, from 2015 to 2021, Seoul Medical Group and Dr. Cha submitted diagnoses for two severe spinal conditions, spinal enthesopathy and sacroiliitis, for patients who did not suffer from either of these conditions. When Seoul Medical Group was questioned by an MA Plan about its use of spinal enthesopathy, Seoul Medical Group enlisted the assistance of Renaissance Imaging Medical Associates to create radiology reports that appeared to support the spinal enthesopathy diagnosis. Both diagnoses resulted in an increase in payment from CMS to the MA Plan, and the MA Plan then passed along a portion of the increased payment to Seoul Medical Group. 

“Providers who game the Medicare program to increase profit undermine the foundation of care and diminish patient trust in the nation’s public health care system,” said Deputy Inspector General for Investigations Christian J. Schrank of the Department of Health and Human Services Office of Inspector General (HHS-OIG). “HHS-OIG will continue to collaborate with our law enforcement partners and rigorously probe false claims to the fullest extent possible.”

The civil settlement resolves claims brought under the qui tam or whistleblower provisions of the False Claims Act by Paul Pew, the former Vice President and Chief Financial Officer of Advanced Medical Management. Under those provisions, a private party can file an action on behalf of the United States and receive a portion of any recovery. The qui tam case is captioned United States of America ex rel. Pew v. Seoul Medical Group, Inc., et al., No. 2:20-cv-05156 (C.D. Cal.). The relator’s share of the settlement has not yet been determined.

The resolution obtained in this matter was the result of a coordinated effort between the Justice Department’s Civil Division, Commercial Litigation Branch, Fraud Section, and the United States Attorney’s Office for the Central District of California, with assistance from the Department of Health and Human Services Office of the Inspector General.

The investigation and resolution of this matter illustrates the government’s emphasis on combating healthcare fraud. One of the most powerful tools in this effort is the False Claims Act. Tips and complaints from all sources about potential fraud, waste, abuse, and mismanagement, can be reported to the Department of Health and Human Services at 800-HHS-TIPS (800-447-8477).

Assistant United Sates Attorney Karen Y. Paik of the Civil Division’s Civil Fraud Section and Trial Attorneys J. Jennifer Koh and Robbin O. Lee of the Justice Department’s Fraud Section investigated this matter.

The claims resolved by the settlement are allegations only and there has been no determination of liability.
