OMAHA, Neb. (AP) — People who visit doctors or hospitals in the state associated with the Catholic Health Initiatives network may soon have to pay more if they have insurance from Blue Cross Blue Shield of Nebraska.

The contract between the big insurer and the medical network may expire Sunday because the two sides have been unable to agree on rates since Blue Cross voided the deal in June.

Both sides complain the other refuses to give up much in negotiations.

If an agreement can’t be reached, all the Omaha-area doctors associated with Catholic Health Initiatives and CHI Health’s hospitals statewide will no longer be in Blue Cross’ network.

If that happens, going to an affected CHI Health facility or doctor will become significantly more expensive for Blue Cross policyholders.
