DAYTON, Ohio -- A health insurance company is dropping a local hospital network because they said it is too expensive.

Medical Mutual will no longer cover services within Premier Health Partners. Their agreement will come to an end on Jan. 1, 2010.

This is the third time in five years that a private health care insurer has ended its agreement with Premier Health Network

Premier Hospitals include Miami Valley Hospital, Good Samaritan Hospital, Atrium Medical Center and Miami Valley Hospital South.
