Massachusetts should save hundreds of millions under the federal Affordable Care Act, but some workers could end up paying more for coverage.

State health officials say that the state could reap an additional $200 million in federal reimbursements during the current fiscal year and $400 million in the fiscal year that begins next July.

Health officials said the new law could also mean higher health care costs for some workers and lower costs for others. Massachusetts is working to reconcile its 2006 health law with the 2010 federal law.
