Raleigh Medical Group Joins Millennium in Major Value-Based Care Push

RALEIGH, NC – May 13, 2026 – Raleigh Medical Group (RMG), a prominent physician-led practice with over 50 years of history in North Carolina, has announced a strategic partnership with Millennium Physician Group, a national powerhouse in value-based healthcare. The collaboration is set to significantly expand and reshape how care is delivered to Medicare and Medicare Advantage patients across the state, signaling a major acceleration in the transition away from traditional fee-for-service medicine.

Under the agreement, RMG will join Millennium's North Carolina risk-based entity. This move enables the two organizations to collaboratively manage patient health under a value-based care model, which incentivizes positive health outcomes and cost efficiency over the sheer volume of procedures performed. The partnership will begin with Medicare Advantage contracts in 2026 and is slated to advance toward full-risk arrangements and participation in an Accountable Care Organization (ACO) by 2027.

North Carolina's Evolving Healthcare Ecosystem

This partnership does not exist in a vacuum. It lands squarely in the middle of North Carolina's deliberate and systemic shift towards value-based care. State health officials and major private insurers have been actively steering the healthcare industry in this direction for years. The North Carolina Department of Health and Human Services (NCDHHS) has been a vocal proponent, embedding value-based payment requirements into its contracts with Prepaid Health Plans that manage the state's Medicaid program.

The private sector has been equally aggressive. Blue Cross NC's "Blue Premier" program, a value-based initiative with major health systems, has reportedly saved hundreds of millions of dollars while improving quality metrics. This environment creates immense pressure on independent physician groups to adapt or risk being left behind.

The partnership’s focus on Medicare and Medicare Advantage patients is particularly strategic. North Carolina has seen explosive growth in Medicare Advantage enrollment, with nearly 1.2 million residents—or 55% of all eligible beneficiaries—now covered by these private plans. This demographic represents a critical and expanding market, making it a focal point for innovative care models. By joining forces, RMG and Millennium are positioning themselves to compete effectively in this crowded space, where success is increasingly defined by the ability to manage patient health proactively and efficiently.

A Model of Independence and Scale

For Raleigh Medical Group, the decision represents a strategic answer to a common dilemma facing independent practices: how to gain the resources needed to succeed in value-based care without being completely absorbed by a larger entity. The partnership is designed to provide the best of both worlds.

"As we continue to evolve in a value-based environment, it was critical for us to find the right partner to support our physicians and our patients," said Dr. Brian Short, president of RMG, in the official announcement. "We chose Millennium Physician Group for their expertise in risk-based care and their ability to provide the infrastructure, data and alignment needed to succeed, without compromising our independence."

Millennium, a subsidiary of the national care delivery platform Mosaic Health, brings a formidable arsenal of tools and a proven track record. The Florida-based group is not merely a participant but a demonstrated leader in value-based arrangements. Its Accountable Care Organization, for instance, has generated shared savings for the federal Medicare program for nine consecutive years. In 2022 alone, Millennium's ACO saved Medicare over $55 million while achieving a near-perfect quality score of 98.78%.

This expertise is what RMG will now tap into. Millennium will provide advanced infrastructure for risk adjustment, data analytics, and performance programs designed to meet rigorous quality benchmarks like CMS Star Ratings. This allows RMG physicians to focus on patient care while being supported by a powerful back-end system that manages population health data and identifies opportunities for preventive intervention.

Dr. Kevin Spencer, national chief medical officer of Millennium Physician Group, emphasized this supportive role. "We are proud to partner with Raleigh Medical Group, working alongside their physicians to bring the capabilities, infrastructure and alignment needed to succeed in risk-based arrangements while preserving their independence and physician-led approach," he stated.

What Value-Based Care Means for Patients and Doctors

Beyond the corporate strategy and financial metrics, the shift to value-based care has tangible implications for both patients and their doctors. For the Medicare beneficiaries served by Raleigh Medical Group, this partnership promises a more coordinated and proactive healthcare experience.

In a value-based model, the focus moves from treating sickness to maintaining wellness. Patients, especially those with chronic conditions like diabetes or heart disease, can expect more consistent monitoring and communication from their care teams. The goal is to prevent costly and debilitating health crises before they happen by managing conditions effectively, ensuring medication adherence, and promoting preventive screenings. Access to Millennium's data analytics will help RMG identify at-risk patients and intervene earlier.

For the physicians at RMG, the partnership will catalyze a shift in practice patterns. Success will be measured not just by the number of patients seen, but by the overall health of their patient panel. Compensation will increasingly be tied to quality metrics and patient outcomes. While this represents a significant change, the support provided by Millennium is designed to ease the transition. By handling much of the complex data analysis and reporting, the partnership aims to reduce the administrative burden on physicians, allowing them to leverage data-driven insights in their clinical decision-making. Crucially, RMG's physician-led structure remains intact, ensuring that clinical autonomy is preserved.

The National Strategy Behind a Local Partnership

This collaboration between a respected local practice and a national giant is emblematic of a much larger trend in American healthcare. Millennium Physician Group operates as a key business unit under Mosaic Health, a national platform formed through a partnership between Elevance Health and the private equity firm CD&R. Mosaic's explicit strategy is to build a national network of physician groups equipped to thrive in risk-based payment models.

The expansion into North Carolina via the RMG partnership is a textbook execution of this strategy. It allows Mosaic and Millennium to enter a new, high-growth market by partnering with an established local entity that has deep community roots and patient trust. This model is highly scalable, combining local physician leadership with the capital, technology, and operational expertise of a national organization.

By joining Millennium's risk-based entity, RMG gains immediate access to a proven model for managing financial risk and achieving quality targets, something that would be incredibly difficult and expensive to build from scratch. For Millennium and its parent company, the deal expands their national footprint and further validates their platform approach to transforming primary care. This synergy reflects the future of healthcare, where success depends on the ability to combine local care delivery with the power of national-scale data and infrastructure.
