Prominent SoCal “Rehab Riviera” Founder and Ex-CEO Arrested

The founder and former CEO of the now-defunct Sovereign Health Group addiction treatment provider was arrested on an eight-count federal grand jury indictment alleging he submitted more than $149 million in fraudulent claims to health insurers – including for fraudulent urinalysis claims – and, in addition, paid more than $21 million in illegal kickbacks for patient referrals.

Tonmoy Sharma, 61, of Tustin, was arrested at Los Angeles International Airport and is expected to make his initial appearance and be arraigned in United States District Court in downtown Los Angeles.

Sharma is charged with four counts of wire fraud, one count of conspiracy, and three counts of illegal remunerations for referrals to clinical treatment facilities.

Also arrested was co-defendant Paul Jin Sen Khor, 45, of Irvine, who worked as Sovereign’s cash management and accounts payable supervisor. Khor is charged with one count of conspiracy and one count of illegal remunerations for referrals to clinical treatment facilities. Khor was arraigned in United States District Court in Santa Ana. He pleaded not guilty and a July 29 trial date was scheduled. A federal magistrate judge ordered him released on $20,000 bond.

According to the indictment, the San Clemente-based Sovereign once was a prominent addiction treatment provider throughout Southern California and several other states. From 2014 to 2020, Sovereign billed private insurance companies for drug addicted and mentally ill patients often at high, out-of-network rates.

At Sharma’s direction, Sovereign employees aggressively pursued patients through various forms of marketing, directing the patients to contact the company at its toll-free phone number. Once patients called in to Sovereign’s call center, employees used various tactics to enroll patients into the company’s treatment facilities, including misrepresentations. One such misrepresentation was that a patient’s treatment would be paid for by a foundation funded by donations from former Sovereign patients.

In fact, the foundation was a sham organization and a ruse for Sovereign employees – at Sharma’s direction – to obtain patients’ names, dates of birth, and Social Security numbers for use in surreptitiously obtaining health insurance coverage on their behalf. In order to obtain these private health insurance plans, Sovereign employees, at Sharma’s direction, made false representations on insurance applications, claiming qualifying life events that had not happened in order to obtain new insurance outside the enrollment period and inflating or underreporting their income so the patients would qualify for Affordable Care Act government-subsidized private insurance instead of Medicaid, whose reimbursement rates were significantly lower than private insurers.

Patients generally did not know that Sovereign would enroll them into these policies or authorize Sovereign to do so. Sovereign employees at times even pretended to be the patients when calling into those insurance companies. Those insurance companies would not have covered any services under plans obtained by these fraudulent means.

Sovereign also fraudulently billed insurers more than $29 million for urinalysis tests not authorized by the purported ordering health providers. At Sharma’s direction, Sovereign submitted fraudulent claims for comprehensive urinalysis screening, including through its laboratory, Vedanta Laboratories Inc. Sovereign patients were frequently drug tested through both cup testing and comprehensive panel testing. The cup testing returned results within minutes, while the panel testing was much more comprehensive, with results taking several days to return. The comprehensive panel testing screened for dozens of different substances and, accordingly, was billed at a significantly higher rate than cup testing.

Sharma directed Sovereign employees to frequently administer cup testing and comprehensive panel testing on patients, including comprehensive panel testing up to three times a week. Sovereign submitted thousands of claims to insurance companies, including for comprehensive panel tests that purportedly were authorized by physicians when, in reality, the physicians did not authorize the tests. Sovereign also submitted numerous claims to the insurance companies, including urinalysis tests, after physicians were no longer working at Sovereign.

Finally, in addition to the patients obtained through the call center above, Sharma and Khor also procured patients for Sovereign by paying illegal kickbacks to patient brokers. To conceal the nature of these transactions, Sharma and Khor caused Sovereign to enter sham contracts that referred to the brokers’ services as “marketing hours,” a term the brokers used when sending invoices to Sovereign for payment. Sovereign paid more than $21 million in illegal kickbacks for patient referrals.

A 2017 investigative series, “Rehab Riviera,” by the Southern California News Group highlighted widespread fraud and lack of oversight in the industry, with Sovereign Health as a key example. Families and advocates have also criticized Sharma’s facilities for negligence, linking poorly run centers to patient deaths, including overdoses.

In 2022, a Los Angeles jury ordered Sharma and Sovereign Health to pay nearly $45 million to Health Net for fraudulent claims, finding that they acted with “malice, oppression, or fraud” and violated the Racketeering Influence and Corrupt Organizations Act (RICO).

Additionally, in 2008, the British General Medical Council revoked Sharma’s medical license in the UK for lying about his academic qualifications and conducting unethical drug studies. Despite this, he became CEO of Sovereign Health in 2009.

San Diego Dermatologist Faces 22 Charges for $1.3M Fraud

Felony charges have been filed against Ghada Kalsho Kassab M.D, a 57 year old San Diego dermatologist, for a $1.3 million Medi-Cal fraud scheme. The investigation uncovered that the dermatologist charged Medi-Cal $1,386,995 for services that were never rendered.

According to the Medical Board of California, Kassab currently holds a Physician and Surgeon license (A 114457). The physician is reportedly a 1999 graduate of the University of Baghdad College of Medicine. Kassab practices dermatology at GK Dermatology of San Diego, located at 3737 Moraga Ave, Ste A206, San Diego, CA 92117.

A complaint was filed in San Diego County Superior Court charging the dermatologist with 22 counts of healthcare insurance fraud, one count of Medi-Cal fraud, the white-collar crime enhancement, and the excessive takings enhancement.

Prosecutors alleged that the dermatologist was invoicing for as many as 233 patients on a daily basis, averaging between 60 to 70 patients per day for identical or comparable services.

Furthermore, it was found that all patients were undergoing light therapy, with the majority using non-medical lamps.

It was further alleged that the crimes committed by defendant Ghada Kassab involved a pattern of related felony conduct, and the pattern of related felony conduct involving the taking of, and resulted in the loss of more than five hundred thousand dollars ($500,000), within the meaning of Penal Code §186.11 (a)(2). This enhancement is known as the aggravated white collar crime enhancement

Pursuant to Penal Code §1170(h), prison custody time is to be served in state prison if the enhancement pursuant to Penal Code §186.11(a)(2) is imposed as part of a sentence for the offenses.

Woman Arrested for Staged Carjacking and Insurance Fraud

The Madera County Sheriff’s Office arrested 57-year-old Martha Gutierrez DeRomero. She is facing a felony insurance fraud charge after claiming two men stole her van with thousands of dollars’ worth of items inside – but, according to Sheriff Tyson Pogue, that was a lie.

On May 23, 2025, DeRomero reported a carjacking at knifepoint near Avenue 21 and Road 26. She claimed an unknown assailant stole her white Chevrolet panel van, which contained $60,000 worth of merchandise.

The Madera County Sheriff’s Office, led by Sheriff Tyson Pogue, investigated the incident and discovered it was a staged event orchestrated by DeRomero and her boyfriend, Alfredo Delezma, to commit insurance fraud.

The investigation revealed that the van, reported stolen, was later found by the Merced County Sheriff’s Office in a storage facility in Merced, along with the supposedly stolen merchandise. This discovery unraveled the scheme, confirming that no carjacking had occurred.

On May 28, 2025, DeRomero was arrested and booked into Madera County Jail on charges of felony insurance fraud, conspiracy, and filing a false police report. Authorities indicated that Alfredo Delezma may also face charges for his role in the conspiracy, although no further details on his status were provided in the reports.

The case was reported by multiple news outlets, including ABC30 Fresno, ABC7 Los Angeles, ABC7 Chicago, and KMPH, all citing the Madera County Sheriff’s Office.

Sheriff Pogue commended the deputies for their thorough investigation, which prevented an fraudulent insurance claim. For further information, contact the Madera County Sheriff’s Office at (559) 675-7770 or visit www.maderacounty.com/sheriff.

No Retroactive Application for PAGA One Year Statute of Limitations

Edgar Osuna worked for Spectrum Security Services, Inc., from October 2011 to February 2022. During his tenure Spectrum allegedly committed Labor Code violations against Osuna and other employees. The violations against other employees purportedly continued after Osuna’s employment terminated.

In August 2023, Osuna notified the Labor and Workforce Development Agency (LWDA) of Spectrum’s alleged failure to comply with the Labor Code. After the LWDA failed to respond within the statutory period Osuna filed a representative PAGA claim based on the underlying violations identified in Osuna’s LWDA notice, and individual and class claims based on the same allegedly unlawful conduct.

Spectrum demurred to the PAGA claim. It argued the applicable one-year statute of limitations bars the claim because Osuna did not provide the LWDA with notice of the alleged Labor Code violations until 18 months after his employment ended. Spectrum also argued Osuna lacks standing to bring his PAGA claim because he was not employed during the time he sought to represent other aggrieved employees. (Citing Robinson v. Southern Counties Oil Co. (2020) 53 Cal.App.5th 476 (Robinson).) It urged the trial court to sustain the demurrer without granting leave to amend.

The trial court agreed with Spectrum’s argument and dismissed Osuna’s class claims, sent his individual claims to arbitration, and sustained Spectrum’s demurrer to his representative PAGA claim without granting leave to amend. It concluded that Osuna lacked standing to bring the PAGA claim because he did not suffer a Labor Code violation during the one-year statute of limitations period for recovering civil penalties.

The Court of Appeal reversed the portion of the order sustaining Spectrum’s demurrer to Osuna’s representative PAGA claim in the published case of Osuna v. Spectrum Security Services, Inc. CA2/6 – B338047 – (May 2025).

Before turning to the issue of representative PAGA standing, the Court of Appeal resolve the threshold issue of appealability. Spectrum contended that it should dismiss Osuna’s appeal because “an order sustaining a demurrer to [fewer] than all of the [claims in a complaint is not immediately appealable.” It also contends the “death knell” doctrine – an exception to this general rule – is inapplicable here because Osuna has not shown that the trial court’s order was “a de facto final judgment for absent plaintiffs.”

The Court of Appeal concluded “the Miranda rule applies here.” (citing Miranda v. Anderson Enterprises, Inc. (2015) 241 Cal.App.4th 196) The order dismissing the representative PAGA claim without leave to amend operates as “a de facto final judgment for absent plaintiffs” (In re Baycol Cases I & II (2011) 51 Cal.4th 751, 759) and is appealable”

Due to the systemic underenforcement of the Labor Code, the Labor Code Private Attorneys General Act of 2004 (Labor Code,1 § 2698 et seq.; PAGA) deputizes employees to stand in the shoes of the state to pursue civil penalties on behalf of themselves and other “aggrieved employees.” (Arias v. Superior Court (2009) 46 Cal.4th 969, 980 (Arias).) So long as they were employed by the alleged violator and personally suffered at least one Labor Code violation, aggrieved employees have standing to bring representative PAGA actions.

The Legislature recently adopted Assembly Bill No. 2288 (2023-2024 Reg. Sess.), which amended portions of Labor Code § 2699. Among other changes, Assembly Bill No. 2288 “requir[es] an aggrieved employee to have personally suffered the alleged violations within [PAGA’s] one-year statute of limitations.” (Sen. Com. on Judiciary, Rep. on Assem. Bill No. 2288 (2023-2024 Reg. Sess.) as amended June 21, 2024, pp. 15-16.) Because those amendments apply only to lawsuits filed on or after June 19, 2024, they are inapplicable here. (See Stats. 2024, ch. 44, § 1.)

If after notification the LWDA does not investigate, does not issue a citation, or fails to respond to the notice within 65 days, the employee may sue. But not every private citizen can maintain such a suit. Only an “aggrieved employee” has PAGA standing.The Labor Code defines such an employee as “any person who was employed by the alleged violator and against whom one or more of the alleged violations was committed.” The issue here is whether Osuna meets that definition. The Court of Appeal concluded that he did.

“The words of section 2699, former subdivision (c) are clear and unambiguous: To have standing to bring a PAGA action, “[t]he plaintiff must be an aggrieved employee, that is, someone ‘who was employed by the alleged violator’ and ‘against whom one or more of the alleged violations was committed.”

Chula Vista Man Pleads Guilty in $51M DME Kickback Scheme

Chula Vista resident and businessowner Fernando Valenzuela Ayub pleaded guilty in federal court, admitting that he conspired with others to launder millions of dollars of health care fraud proceeds and paid unlawful kickbacks.

According to his plea agreement, Valenzuela and co-conspirators owned and operated multiple durable medical equipment (DME) companies, which sold orthotics – including back, wrist, and knee braces – to Medicare beneficiaries.

Valenzuela admitted that in operating the DME companies, he and co-conspirators paid unlawful kickback payments to sham marketing companies who provided bogus prescriptions for DME. In total, Valenzuela paid $3.7 million in kickbacks.

Valenzuela admitted that he used his DME companies to submit fraudulent claims to Medicare. Once Valenzuela’s DME companies were suspended from billing Medicare, Valenzuela conspired to put DME companies in the names of nominee owners while he maintained control of the companies and the monies received from Medicare.

In total, Valenzuela billed Medicare approximately $51 million and was paid approximately $20 million, and ultimately laundered at least $14 million dollars of Medicare proceeds. As part of his guilty plea, Valenzuela agreed to forfeit $7,101,320.

Valenzuela’s sentencing is scheduled for August 15, 2025. The case is being prosecuted by Assistant U.S. Attorney Blanca Quintero of the Southern District of California.

$147M Verdict Against Johnson & Johnson in SoCal Antitrust Case

Beckers Hospital Review just reported that in May 2025, a federal jury in the U.S. District Court for the Central District of California awarded $147 million in damages to Scottsdale, Arizona–based Innovative Health, a medical device reprocessor, in a lawsuit filed in 2019 against Johnson & Johnson’s subsidiary, Biosense Webster.

The jury found that Biosense Webster violated federal antitrust laws (Sherman Antitrust Act, Sections 1 and 2 and California Cartwright Act) by engaging in anticompetitive practices, specifically by withholding clinical support from hospitals that used reprocessed catheters instead of purchasing new ones from Biosense.

The lawsuit centered on Biosense Webster’s policy of tying access to clinical support for its CARTO 3 cardiac mapping system to the exclusive purchase of its high-density mapping and ultrasound catheters.

Innovative Health alleged that this policy, implemented after they received FDA clearance in 2016 to reprocess Biosense’s catheters, pressured hospitals to buy new devices, stifling competition and maintaining Biosense’s monopoly in the cardiac mapping catheter market.

Internal emails presented during the trial showed hospitals expressing interest in Innovative’s cost-effective reprocessed catheters but facing warnings from Biosense about discontinued support.

Biosense defended the policy, arguing it was necessary to ensure service quality and prevent competitors from “free-riding” on their clinical support infrastructure.

However, the jury sided with Innovative Health, determining that the tying arrangement and monopolistic practices were illegal.

The case was initially dismissed in 2022 but revived by the Ninth Circuit Court of Appeals in 2023, leading to the trial that began in April 2025.

Association of Medical Device Reprocessors issued the following statement: “Friday’s unanimous verdict by a federal jury in Santa Ana, California for Innovative Health against Johnson & Johnson (NYSE: JNJ) is a victory for America’s hospitals, providers, patients, and the environment. The jury found that Biosense Webster violated federal and state antitrust laws by withholding clinical support to hospitals using Innovative Health’s FDA regulated, reprocessed catheters.”

For too long, Johnson & Johnson has used tying arrangements and other tactics to interfere with fair competition from lower-cost, FDA-regulated, reprocessed ‘single-use’ devices (SUDs),” the association’s CEO Daniel J. Vukelich said in a news release. “We hope this jury’s message will be heard loud and clear: Hospitals want to reduce costs and greenhouse gas emissions by using more reprocessed SUDs without fear of retribution by their original equipment manufacturers (OEMs).”

The verdict is seen as a significant win for reprocessors and hospitals seeking cost-effective, FDA-regulated reprocessed devices to reduce costs and environmental impact.

OSHA Updates its Inspection Program Focus

The U.S. Department of Labor’s Occupational Safety and Health Administration announced it has updated the inspection program that directs agency enforcement resources to establishments with the highest rates of injuries and illnesses based on injury and illness data submitted in accordance with OSHA’s recordkeeping requirements.

The Site-Specific Targeting program is OSHA’s primary planned inspection program for non-construction establishments with 20 or more employees. Using OSHA Form 300A data from calendar years 2021-2023, establishments may be selected for inspection based on:

– – High injury and illness rates from 2023 data.
– – Upwardly trending injury and illness rates based on 2021-2023 data at or above twice the 2022 private sector average.
– – Injury and illness rates markedly below industry averages.
– – Failure to submit an OSHA Form 300A in 2023.

The new directive replaces the previous SST program directive issued on February 7, 2023. OSHA also uses national and local emphasis programs to target high-risk industries and hazards. Learn more about these emphasis programs.

OSHA’s On-Site Consultation Program provides free, confidential occupational safety and health services to help small- and medium-sized businesses identify workplace hazards, comply with OSHA standards, and establish and improve safety and health programs. On-Site Consultation services are separate from enforcement and do not result in penalties or citations.

Court Finds United Indian Health Immune From WCAB Jurisdiction

Deborah Hemsted’s workers’ compensation claim is based on an injury she sustained on September 24, 2014, when she was a Medical Assistant III for United Indian Health Service at Arcata, California.

The history of the United Indian Health Services began in 1968. It was a time when Native activism coincided with the nation-wide Civil Rights Movement and the Office of Economic Opportunity programs. Together these factors helped create a new era of self-determination for Indian peoples.

Hemsted first received benefits and treatment for her injury through United Indian’s tribal workers’ compensation system. After a dispute arose, Hemsted filed a claim with the state workers’ compensation system. United Indian took the position that, in light of its tribal immunity, California’s workers’ compensation system lacked jurisdiction to adjudicate the claim.

In a March 2024 decision, the workers’ compensation administrative law judge (ALJ) rejected United Indian’s claim of sovereign immunity after applying the California Supreme Court Miami Nation’s five-factor arm-of-the-tribe test. (People v. Miami Nation Enterprises (2016) 2 Cal.5th 222.)

With respect to United Indian’s method of creation, the ALJ found that it was a California non-profit created through the Indian Health Board and authorized by several tribes, including federally recognized tribes, to provide health services to their members. The ALJ observed that eight or nine tribes have sanctioned United Indian as their health provider. The ALJ noted that most of the tribal resolutions did not specifically designate United Indian as a tribal organization. Based on these circumstances, the ALJ concluded that United Indian’s method of creation weighed against sovereign immunity.

As to the question of intent, the ALJ found no evidence that the tribes intended to share their sovereign immunity with United Indian. The ALJ held that United Indian’s purpose – to serve the health needs of Indians in Humboldt and Del Norte Counties – weighed in favor of sovereign immunity.

As for control, the ALJ concluded that “[c]ontrol weighs against sovereign immunity because the Board [of Directors of United Indian] consisted of tribal members and others who may or may not be tribal members.”

With respect to the financial relationship between United Indian and the tribes, the ALJ found United Indian was not funded by the tribes, but instead by grants obtained by the Indian Health Board and distributed to United Indian. The ALJ reasoned that, because United Indian is incorporated separately from the tribes, “any action against [United Indian] would not threaten the tribes’ resources, nor the resources of the members of the board.” The judge therefore concluded that this factor weighed against immunity.

In her report on reconsideration, the ALJ recommended that the Board deny United Indian’s request for reconsideration. The ALJ appeared to change her view on the funding factor, stating: “Defendant’s argument on Reconsideration with regard to funding is well made. The[ir] point [that] any monies lost through suit would not be available to [United Indian] to provide medical treatment to the tribes weighs in favor of sovereign immunity.” However, the ALJ’s overall assessment remained that United Indian had failed to establish its entitlement to sovereign immunity.

Denying United Indian’s reconsideration request, the Board adopted and incorporated the ALJ’s report on reconsideration. The Board found no abuse of discretion in the ALJ’s rejection of United Indian’s claim of sovereign immunity.

The Court of Appeal granted a petition for writ of review, and reversed the Boards decision in the unpublished case of United Indian Health etc. v. Workers’ Comp. Appeals Bd. – A170950 – (May 2025).

No one Miami Nation factor of the five-factor test is dispositive.” Whether sovereign immunity applies to an entity is a question of law reviewed de novo. (Miami Nation, supra, 2 Cal.5th at p. 250.) the Court of Appeal also applid the de novo standard when interpreting written instruments, except to the extent that the interpretation turns on conflicting extrinsic evidence.

Considering both the law and the circumstances under which United Indian was formed (Miami Nation, supra, 2 Cal.5th at pp. 245-246), the method of creation factor weighs somewhat in favor of sovereign immunity.

The ALJ concluded the tribes had no intent to share their sovereign immunity with United Indian. The record contained no tribal documents stating the tribes’ intent to extend sovereign immunity to United Indian. “However, that even absent express statements of a tribe’s intent, tribal intent may be inferred from the tribe’s actions or other circumstances.” And as United Indian asserts, it may be possible to infer the intent to share tribal immunity based on the fact that the tribes established and sanctioned United Indian to provide healthcare services to tribe members under a federal system intended to further tribal self-governance.

The Court of Appeal agreed with the ALJ that United Indian’s provision of health care serves a purpose central to tribal self-sufficiency and self-governance, weighing in favor of sovereign immunity

The control factor also weighs in favor of sovereign immunity. The tribes participate in the management and control of United Indian in at least three respects.

Finally, the financial relationship factor likewise weighs in favor of immunity. Miami Nation makes clear that where a judgment against the tribal entity would significantly reduce tribal resources, sovereign immunity is appropriate, even if the tribe’s treasury is not directly affected.

“In sum, although there is no express evidence that United Indian’s participating tribes intended to share their immunity, the remaining factors reflect that United Indian is an arm of the tribes that it serves.”

Security Company Owner Sentenced for $3.4 M Premium Fraud

The owner of a San Jose-based security company, Raul Chavez, 40, was sentenced after a California Department of Insurance investigation uncovered a six year-long scheme to underreport payroll and avoid paying workers’ compensation insurance premiums.

Chavez pleaded guilty to felony premium fraud, sentenced to 180 days in county jail, two years of formal probation, and ordered to pay $225,168 in restitution to the State Compensation Insurance Fund (State Fund). Chavez has paid his restitution and served his jail time on electric monitoring.

“Premium fraud puts workers at risk and shifts the financial burden to honest employers who follow the law,” said Insurance Commissioner Ricardo Lara. “This case is a clear example of our commitment to protecting workers and holding those accountable who try to game the system. Thank you to the Santa Clara County District Attorney’s Office for their partnership and dedication in bringing this case to justice. ”
Chavez owned and operated Tactical Operations Protective Services, a limited liability company providing security guard, staffing, and patrol services in Santa Clara County. The Department received a suspected fraud referral in September 2023 from State Fund alleging Chavez failed to report an employee injury that occurred in June 2022. The referral further alleged Chavez had significantly underreported payroll for multiple security guards over a six-year period.

Although Chavez transported the injured worker to an emergency room on the date of the injury, he failed to notify State Fund or report the incident as required. The Department’s investigation revealed that from 2017 to 2022, Chavez had falsely claimed to State Fund that he had no employees or payroll. For the 2022 to 2023 policy year, he reported only $40,000 in payroll related to the injured employee.

However, the Department’s audit uncovered that Chavez concealed $3,431,903 in payroll from 2017 through 2023. This underreporting resulted in an estimated $205,565 in unpaid workers’ compensation premiums owed to State Fund.

The case was prosecuted by the Santa Clara County District Attorney’s Office.
