Dr. Mehmet Oz, Administrator of the U.S. Centers for Medicare and Medicaid Services, characterized this action as the most significant deferral ever undertaken by the agency. Speaking at a recent press conference, Dr. Oz highlighted California as an anomaly, noting its home health expenditures are growing at twice the rate of other states. The federal government has indicated that the funds will remain withheld until California can provide a satisfactory explanation for this accelerated growth.

At the heart of the dispute is the IHSS program, which provides essential assistance with daily living activities for approximately 900,000 Californians, enabling them to remain in their homes rather than transitioning to institutional settings. This federal action is poised amidst the administration’s broader crackdown on perceived fraud within the nation’s Medicare and Medicaid systems. Despite federal officials raising concerns about the integrity of California's home health program, specific supporting evidence for these claims has not been publicly unveiled, according to statements from California health authorities.

Tyler Sadwith, California’s state Medicaid director, countered the federal assertions, explaining that the program’s expansion is a deliberate policy outcome. He attributed the growth to a trifecta of factors: an increasing caseload, a rise in hourly wages for home health workers, and an escalation in service hours to meet the needs of a more vulnerable population. Data from the state’s Department of Health Care Services, which oversees Medi-Cal, California’s Medicaid program, indicates a 17.5% increase in caseload between 2023 and 2025, alongside an average hourly wage increase for caregivers from $19 to $21. Governor Gavin Newsom, during a recent budget presentation, underscored the cost-effectiveness of home-based care, noting its annual cost of approximately $30,000 per person, significantly less than the four to five times higher expense of skilled nursing facilities. He argued that such expansion should be commended, not penalized.

California health officials maintain that robust oversight mechanisms are in place to combat fraud within the system. These include annual assessments, electronic timesheets, various verification tools, and a coordinated state-county review process. In addition to the $1.1 billion freeze on home health funding, an extra $200 million tied to administrative claims is also being withheld, a matter the state anticipates resolving. This federal intervention in California echoes a similar action taken in Minnesota in February, where $259 million in Medicaid payments were suspended, prompting a lawsuit from the state to block the freeze.

Vice President JD Vance, who leads the administration's fraud task force, further amplified federal concerns at the press conference, accusing California, New York, and Hawaii of insufficient efforts to combat Medicaid fraud. “This is why we’re taking this action,” Vance stated, urging California to adopt a more serious stance on fraud prevention. The administration has focused particular scrutiny on California’s hospice care, and simultaneously announced a six-month nationwide moratorium on new hospice providers enrolling in Medicare, a measure California had already implemented independently. While state health officials assure that services for current home health patients will remain uninterrupted, advocates and unions, including Doug Moore, executive director of United Domestic Workers, voice mounting concerns over the indefinite timeline for fund release and the potential long-term ramifications for vulnerable clients, emphasizing that innocent individuals should not be caught amid political disputes over essential services.
