GRAND ISLAND, Neb. (AP) — The Grand Island City Council has decided to outsource its ambulance billing service to a Fortune 500 company, though the cost of the contract hasn’t been disclosed.

The council voted 7-2 Tuesday to approve McKesson Corp.’s proposal to handle annual billing services for what has typically contributed about $1.2 million in ambulance revenue to the Grand Island Fire Department.

Councilman Mike Paulick voted against the plan, saying he’d prefer to keep the billing service local. And Councilman Roger Steele says he rejected the move after he found out McKesson refused to reveal its contract cost.

City Attorney Bob Sivick says the cost was confidential because the company’s billing formula is considered a trade secret, as protected under Nebraska’s open records law.
