The Trump administration has acknowledged that it made a major mistake in the numbers it used to justify a fraud investigation led by Dr. Mehmet Oz into New York's Medicaid program, a reversal that is raising new questions about the reliability of its broader anti-fraud push in several states.
At the center of the dispute is a claim made last month by Dr. Oz, the administrator of the Centers for Medicare & Medicaid Services (CMS), who said New York's Medicaid program had provided personal care services to roughly 5 million people in the previous year. That figure would have represented an astonishing share of the state's 6.8 million Medicaid enrollees and helped fuel the administration's accusation that New York's system demanded closer federal scrutiny.
