US-based physician enablement company Privia Health Group has announced its expansion into Arizona through a partnership with Integrated Medical Services (IMS).
The collaboration enables the creation of Privia Medical Group Arizona, offering a new option for independent providers to care for patients across various reimbursement models.
IMS, one of Arizona’s largest independent multi-speciality practices, includes around 70 physicians and practice providers across 21 locations.
The group manages over 28,000 attributed lives through diverse value-based care arrangements, including Commercial, Medicare, Medicare Advantage, and Medicaid.
Under the agreement, IMS will serve as the anchor practice, maintaining its physician-owned and operated status while entering a long-term management agreement with Privia Health.
The implementation on the Privia Platform is anticipated in the fourth quarter of 2025.
Integrated Medical Services president Riyaz Sumar said: “We are excited to align with a partner who sees the value of private practice physicians. It was important for all of us at IMS to find a partner who values our culture.
“Our commitment to our community is deep, and we feel confident Privia will not only help us maintain our culture but grow and improve upon what we’ve built. Together, we will execute on a shared vision to build a scaled, vibrant, private practice provider network in Arizona.
“We look forward to benefiting from Privia’s industry expertise, robust technology and services platform, population health expertise and physician-led governance structure to enable our practice as well as future provider partners to maintain significant autonomy while enhancing patient care and strengthening practice vitality.”
The partnership and Arizona launch are expected to be profitable from the fourth quarter of 2025 and throughout 2026.
It underscores Privia Health’s strategy to build scaled provider networks with primary-care centric medical groups and a physician-led governance structure.
Privia Health operates in 15 states and the District of Columbia, offering an extensive suite of technology and service solutions through the Privia Platform.
Privia Health medical groups EVP Jason Ross said: “We are extremely pleased to partner with IMS, one of the largest independent practices in Arizona, as we expand Privia’s national presence.
“The demographics of the Arizona market offer a compelling value-based care opportunity.
“We look forward to building on the IMS providers’ culture of delivering high-quality care in the community as we continue to execute our strategy of aligning with like-minded providers and practices to offer high-quality care to patients across the US.”
