Currently, the state collects $176 million in hospital tax that pays for Medicaid services and other state spending. At a hearing two weeks ago, the panel learned the federal government allows states to apply their hospital taxes to 19 categories. New Hampshire applies the 5.5 percent tax to inpatient and outpatient hospital revenues.
The state also taxes two other categories - nursing homes and intermediate care facilities - under a different law.
That leaves 15 other categories untaxed, including physician services and ambulatory surgical centers.
Ten of the state's largest hospitals sued over changes in Medicaid policies and reimbursements after the state cut aid.
Wednesday's meeting starts at 8:30 a.m. in Concord.
