Premier cancer treatment center in New York City joins Aetna’s national participating provider network

HARTFORD, Conn,March 11, 2008 — Aetna (NYSE: AET) and Memorial Sloan-Kettering Cancer Center (MSKCC) today announced a new agreement on a three-year contract that adds the Center to Aetna’s provider network. The agreement will take effect on April 1.

"This is an extremely positive development for our members," said Troy Brennan, MD, Aetna chief medical officer. "Memorial Sloan-Kettering Cancer Center is a well established leader in the study, research and, above all, treatment of cancer, and their multidisciplinary, singularly focused approach to treating patients with cancer often leads to better outcomes and strong patient satisfaction. We believe this agreement will come as terrific news to our members and to our customers across the country."

MSKCC has been a part of Aetna’s national Institutes of Excellence network for various adult bone marrow transplant procedures since July 2002, based on a strong track record of providing superior quality and clinical outcomes for these procedures.

Today, approximately 60 Aetna customers have purchased this option.

"Under the agreement, all members of Aetna network-based plans will be able to receive covered in-patient and out-patient services, at in-network rates, from MSKCC," Michael Hudson, president of Aetna’s Northeast Region, leading regional health care delivery operations.
