After announcing partnerships with Chattanooga's two largest hospitals, BlueCross BlueShield of Tennessee has dropped key Parkridge Health System facilities from its "S" network.

Parkridge Medical Center, Parkridge East Hospital and Chattanooga Surgery Center -- which is affiliated with Parkridge -- will be dropped from the BlueCross network as of Oct. 1. Parkridge Valley facilities will not be affected.

Parkridge is still in BlueCross' Network P. Of the two networks, Network P is much larger and covers more doctors and hospitals, but is more expensive.
