Last year, the Texas legislature approved a $350 million cut in Medicaid reimbursement rates to early childhood intervention therapists and providers. The cuts, made to help balance a billion dollars in property tax relief, affect the most vulnerable Texas children — those born extremely prematurely or with Down syndrome or other genetic conditions that put them at risk for developmental delay.For months, providers of in-home physical, speech and occupational therapies have continued to serve children who have disabilities, despite mounting financial losses. Now some have had to shut their doors, curtail services or halt their home-visit programs, leaving many children without treatments their parents feel are crucial to the kids’ well-being.
