An unexpected constituency is nervously tracking the progress of the American Health Care Act, the GOP’s proposal to repeal and replace Obamacare – schools.

The AHCA, which narrowly cleared the U.S. House last week, would dramatically restructure Medicaid from a program that reimburses – at least in part – whatever eligible expenses providers bill for to a per-capita capped program. The GOP bill would give the program $840 billion less over 10 years to spend.

That could deal a big blow to school districts, who rely on Medicaid to help defray the costs of certain medical services provided to students with disabilities.
