GRAND ISLAND, Neb. (AP) — Grand Island has removed a veil over its deal with a company contracted to handle ambulance billings.

The city said in a news release Friday that it will pay PST Services, a McKesson Corp., company, 4 percent of the net amount collected. That would be around $48,000 on the $1.2 million collected in a typical year.

The City Council approved the contract last week but wouldn’t say what the city will pay PST. City Attorney Bob Sivick said the cost was confidential because the company’s billing formula is considered a trade secret, which is protected under Nebraska’s public records law. The Grand Island Independent submitted an open records request.

The city’s news release said “it was determined releasing the information was in the best interest of the community.”
