The Trump administration is expanding its fraud-busting initiative in federal health programs. On Wednesday, it announced a nationwide six-month freeze on new Medicare enrollments by hospice and home health agencies. The Centers for Medicare and Medicaid Services says the moratorium will help prevent fraud and protect vulnerable patients. The initiative was spurred by Vice President JD Vance's anti-fraud task force. Several alleged fraud schemes have been prosecuted in the hospice and home health care categories, and states have acknowledged it's a legitimate concern. But some have pushed back on the administration’s aggressive tactics and raised concerns about punishing law-abiding providers that are trying to serve patients.
