For legislation relative to primary care for you. Health Care Financing. Not later than October 1 of every year, the commission shall hold public hearings based on the report submitted by the center under section 16 of chapter 12C comparing the growth in total health care expenditures to the health care cost growth benchmark for the previous calendar year and comparing the growth in actual aggregate primary care expenditures for the previous calendar year to the aggregate primary care expenditure target.
