A Las Vegas nurse practitioner who operated wound care clinics in Pearland and Manvel has been indicted on federal charges alleging she masterminded one of the largest Medicare fraud schemes ever prosecuted in the Houston area, billing the government for nearly $1 billion in treatments prosecutors say were medically unnecessary, falsified, or administered to patients who were already dying.
Marizel Yukee was indicted June 18 in the Southern District of Texas on charges including conspiracy to commit health care fraud, wire fraud, conspiracy to pay and receive illegal kickbacks, and money laundering, according to the federal indictment. A warrant for her arrest was issued the same day.
Prosecutors allege that between October 2023 and April 2026, Yukee and unnamed co-conspirators submitted more than $906 million in fraudulent claims to Medicare and TRICARE, the federal health insurance program covering military members and their families, through four wound care companies she owned: Wound Medic, My BestHealth First, AllCare Mobile Wound Treatment, and Oracle Wound Treatment. From those claims, the government paid out approximately $297 million, according to the indictment.
The scheme centered on skin-substitute allografts, which are bioengineered from donated placental tissue and used to treat chronic wounds. According to prosecutors, Yukee’s clinics applied those grafts to wounds that were already healed, infected and ineligible for treatment, or to patients who had no qualifying wounds at all. In some cases, hospice patients received grafts and died within days, according to the indictment.
Prosecutors allege Yukee paid health care providers to refer patients to her clinics, and separately received nearly $16 million in kickbacks from allograft distributors whose products she used. In one documented example from the indictment, she paid $1,600 for a graft product and then directed her billing company to invoice Medicare for $3,900, more than double the actual cost. She averaged more than $1 million in billed claims per patient, according to prosecutors.
The indictment accuses Yukee of falsifying patient records to make the treatments appear medically appropriate and of instructing colleagues via email to inflate prices when seeking reimbursement.
Prosecutors allege the proceeds funded an extravagant personal lifestyle.
The indictment identifies a Ferrari valued at more than $500,000, an $865,000 Bulgari diamond necklace, a $1 million home in Hawaii, and a $4.6 million beach resort under construction in the Philippines. Investigators have also seized a Porsche, a Mercedes, an Escalade, two Teslas, and roughly $467,000 in cash.
The government is seeking forfeiture of several properties, including real estate in Hawaii and Las Vegas and a commercial property in Pearland.
The case is not the first time the Houston area has been at the center of large-scale Medicare fraud.
Last July, federal prosecutors announced charges against 22 cases in the Southern District of Texas alone as part of a national health care fraud takedown, including a Spring-based podiatrist accused of billing Medicare more than $90 million for bioengineered skin grafts applied to patients without qualifying wounds, the same type of product at the center of the Yukee case.
Yukee was also sued last year in Nevada federal court by a company called Alerce Biologix, which accused her and her daughter of bilking it out of $29 million in unpaid invoices. Allegedly, Yukee had sought a refund from the company after Medicare began denying her reimbursement claims. That lawsuit was withdrawn in February after the parties reached a private settlement.
