Caldwell Woman Charged in the District of Idaho as Part of the National Health Care Fraud Takedown

BOISE - United States Attorney Bart M. Davis announced criminal charges against defendant Niki Rashel Cook in connection with an alleged scheme to defraud healthcare businesses. The charges filed in federal court are part of the Department of Justice's 2026 National Health Care Fraud Takedown. The charges stem from Cook's alleged scheme to obtain nursing jobs at healthcare businesses by fraudulently representing herself to be a registered nurse and licensed practical nurse.

The charges announced by U.S. Attorney Davis are part of a strategically coordinated, nationwide law enforcement action that resulted in charges against 455 defendants, including 90 doctors and other licensed medical professionals, for their alleged participation in health care fraud and opioid abuse schemes involving over $6.5 billion in false claims and significant patient harm, including death. The Takedown represents a new era in federal, state, and international cooperation to combat health care fraud: cases in 56 federal districts and 45 U.S. states and territories, with 50 state Medicaid Fraud Control Units participating, the most in Department history. In addition, unprecedented international cooperation over the two-week Takedown resulted in the apprehension and return to the United States of the following health care fraudsters: one defendant in Kyrenia in connection with an over $3.7 billion scheme; two defendants in Estonia in connection with a previously charged $10.6 billion scheme; and, in the Philippines, one of FBI's Most Wanted Fraudsters in connection with a previously-charged $1.2 billion telemedicine fraud scheme. The Takedown involves the cutting-edge use of data analytics to target the worst actors; the seizure of over $182 million in cash, luxury vehicles, jewelry, and other assets; and full-spectrum accountability for all criminal actors from doctor's offices to corporate boardrooms.

The coordinated enforcement action involves a whole-of-government approach, including:

• Actions by the Centers for Medicare and Medicaid Services (CMS) to suspend 1,079 providers and revoke billing privileges for 1,403 providers.
• 48 Civil Monetary Payment settlements amounting to over $73 million, over 1,400 provider exclusions, and 25 actions by the U.S. Department of Health and Human Services, Office of Inspector General ("HHS-OIG") under the Civil Monetary Penalties Law seeking more than $10 billion in payments to the Medicare Trust Fund from payments that CMS caught and suspended before the funds were paid to the fraudulent providers.
• Civil charges against 13 defendants for $14.8 million in health care fraud schemes, as well as civil settlements with 31 defendants totaling $23 million.
• 928 administrative cases by the Drug Enforcement Administration (DEA) seeking the revocation of authority to handle and/or prescribe controlled substances since October 1, 2025.

On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division ("Fraud Division"). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department's work to combat fraud supports President Trump's Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.

An indictment, information or complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
