Aetna has partnered with Princeton HealthCare Partners in an integrated network of 125 physicians in New Jersey's Mercer, Middlesex and Somerset counties.
Aetna members already enrolled in a fully insured plan and who have seen a Princeton Healthcare Partners physician in the last year will automatically become part of the collaboration.
The three-year delivery model will track metrics, use advanced technology and leverage analytics to provide care management.
Members who see providers within the network will benefit from lower overall costs, Aetna said.
"We chose Princeton HealthCare Partners because they are committed to providing excellent, evidence-based patient care," said Michael S. Costa, executive director of Aetna's New Jersey market.
Aetna currently has 275 value-based arrangements with approximately 45 percent of Aetna claims payments made to doctors and providers who practice value-based care. Aetna has committed to increasing that number to 75 percent by 2020.
"This is an excellent example of how physicians and our health system can come together to partner with a leading national insurer to improve patient outcomes, provide access to an integrated network of high-quality providers and make healthcare more affordable for patients," said Mark Jones, senior vice president for Network Development at Princeton HealthCare System.
The nonprofit Princeton HealthCare Partners includes Princeton HealthCare System, Princeton Medicine, physician practices and other providers.
Aetna has seven accountable care collaborations in New Jersey, including: Aetna Whole Health Meridian, Aetna Whole Health Virtua, Virtua Medical Group Attribution ACO, Hunterdon Healthcare Attribution ACO, Optimus Attribution ACO, Lourdes Health System ACO, and Hackensack Alliance and Atlantic.
