The Centers for Medicare & Medicaid Services disclosed that it will expand oversight measures affecting hospices in four states. “To combat fraud, waste, and abuse under the hospice benefit, CMS will expand prepayment medical review this September in Arizona, California, Nevada and Texas,” the agency said in a statement Thursday. “To help reduce burden on compliant providers, initial review volumes will be low and adjusted based on results. If you’re noncompliant, we may implement extended review or take additional administrative actions.”
