By State House News Service A week ahead of the House's expected fiscal year 2022 budget reveal, the Baker administration said it has worked up new spending projections for the single largest budget item to account for a federal-level change that could drive up costs by more than $1.4 billion while providing additional revenue to offset most or all of the extra spending. Gov. Charlie Baker's fiscal 2022 budget (H 1) was filed Jan. 27 proposing to trim state spending by about $300 million. That reduction in overall state spending was to be made possible largely thanks to slower-than-expected growth in MassHealth enrollment, Baker budget officials said at the time.
