Texas Children's Hospital filed suit against the state Health and Human Services Commission earlier this month in an attempt to halt looming changes to Medicaid reimbursement — estimated to cost the city's sixth-largest hospital $30 million. Medicaid's Disproportionate Share Hospital program bolsters income for hospitals that provide significant amounts of care to low-income individuals, the Houston Chronicle reports. A change in interpretation of the formula by the Centers for Medicare and Medicaid is what jeopardizes funding for Texas Children's and other children's hospitals in Texas and across the country, according to a statement from the hospital.
