CARSON CITY, Nev. (AP) — A state board approved a $72 million contract Tuesday to implement a health insurance exchange in Nevada under the federal Affordable Care Act, but Gov. Brian Sandoval said the program will need to become self-sustaining if it is to continue.

The contract approved by the Board of Examiners is with Xerox State Healthcare to set up the computer system and operations needed to begin enrolling people by October 2013. Startup costs are being funded through federal grants. So far, Nevada has received $25 million and state officials are awaiting approval, expected in the next few days, on another $50 million.
