Cedars-Sinai Medical Center, in Los Angeles.

Anthem Blue Cross, in Southern California, says its new group of allied providers called Vivity  has exceeded its enrollment target and lured more than half its members from Kaiser Permanente.  However, Modern Healthcare reports,  “it’s also still just beginning to build the data infrastructure to allow its hospitals and doctors to function as a truly integrated network. ”

The news service says  that “Vivity—pitched as an integrated network of seven high-value health systems, including Cedars-Sinai Health System—has signed on 13 large employers to the low-cost narrow network, including seven that weren’t previously Anthem customers. Anthem says that  it has enrolled 24,000 members, compared with 15,000 projected before it launched, and 60-70 percent of them used to belong to Kaiser.”
