Tenet Louisiana Signs New Two-Year Hospital Contract with Humana.

NEW ORLEANS -- Tenet Louisiana today announced that it has signed a new two-year hospital agreement with Humana Health Benefit Plan of Louisiana, Inc., effective March 1, 2005. The agreement provides individuals and families enrolled in Humana's commercial medical plans and Humana Gold Plus plans (CMS MedicareAdvantage plans) access to all covered inpatient and outpatient services at Tenet's five hospitals in New Orleans. The five hospitals are Kenner Regional Medical Center, Lindy Boggs Medical Center, Meadowcrest Hospital, Memorial Medical Center and NorthShore Regional Medical Center. Financial terms of the contract were not disclosed.

"This new contract means continued access to care for Humana members and a strong, ongoing relationship between our two companies," said Robert L. Smith, senior vice president, operations, for the Tenet Texas-Gulf Coast Region. "It also demonstrates that Tenet continues to maintain positive relationships with its managed care partners, and establishes a cooperative, mutually beneficial relationship with one of New Orleans' largest health plans."

"I am particularly pleased that Tenet Louisiana will now be available to members of our senior product offerings, including our Medicare HMO and our newly introduced Medicare PPO," said Hassan Rifaat, M.D., president of Humana Health Benefit Plan of Louisiana, Inc. "But equally important to small and mid-size employers faced with increasing health benefit costs, Humana offers competitive and affordable choice in health benefits along with a comprehensive, statewide hospital and physician network."

The addition of the five Tenet hospitals in New Orleans further strengthens Humana's statewide provider medical network that now offers members a choice of 81 participating hospital providers and more than 7,000 physicians throughout Louisiana.
