Aetna Signature Administrators, the preferred provider organization for the AVMA Group Health & Life Insurance Trust, has expanded its network to include the Mayo Clinic Rochester and Mayo Health System.

"This expansion of the ASA PPO network serves to increase member choice and improve hospital and physician access for our participants by providing them with in-network coverage for care by one of the premier health care organizations in the world," said Dr. Gary Holfinger, GHLIT chair. "It further demonstrates the exceptional network, programs, and health care services provided by ASA to support the evolving needs of Trust participants."

The Mayo Clinic and Mayo Health System providers have locations in various cities and states. Their addition to the ASA network took effect Jan. 1 and expands access to services in Minnesota, Iowa, and Wisconsin—including areas around Eau Claire, Wis. The agreement also includes the Mayo Behavioral Health providers.
