Executive Summary

The U.S. healthcare system stands at a pivotal transformation point, with 100% of original Medicare beneficiaries projected to convert to advanced alternative payment models by 2030. Within this landscape, clinician-led ACOs outperform hospital-anchored, investor-owned, or health plan-anchored models across key metrics, yet physicians and advanced practice providers (APPs) remain underrepresented in global payment arrangements that could fundamentally reshape healthcare delivery.

This white paper introduces the Practice Mutual model: a revolutionary approach that combines provider clinical expertise with total cost of care payments in a scalable, legally compliant structure. Unlike traditional Independent Practice Associations (IPAs) or conventional ACOs, Practice Mutuals represent Physician/APP-owned and Physician/APP-governed entities that accept global payments while maintaining operational independence through strategic Management Service Organization (MSO) partnerships.

The model addresses the fundamental challenge facing healthcare today: how to align clinical excellence with financial accountability while preserving the physician/APP leadership that drives superior outcomes. By creating physician/APP-owned structures that accept total cost of care payments, the model offers a pathway for physicians and APPs to lead healthcare transformation while achieving enhanced compensation and improved patient outcomes.

Introduction

Healthcare payment reform has accelerated beyond incremental change to fundamental transformation. The Centers for Medicare & Medicaid Services (CMS) has committed to moving all Medicare beneficiaries to value-based arrangements by 2030, while commercial payers increasingly demand accountability for both cost and quality outcomes. This shift from fee-for-service to fee-for-value creates unprecedented opportunities for physician/APP-led organizations willing to accept total cost of care payments in exchange for clinical autonomy and enhanced compensation.

Current shared savings programs, while valuable, represent an interim step toward full global payment arrangements. Approximately half of medical practices participate in some form of shared savings, yet the majority remain reluctant to assume global payments due to concerns about capital requirements, regulatory compliance, and operational complexity. This hesitation creates a market opportunity for innovative models that address these barriers while preserving physician/APP leadership and clinical decision-making authority.

Data consistently demonstrates that physician/APP-led ACOs outperform hospital-anchored, investor-owned, or health plan-anchored models across key metrics including cost reduction, quality improvement, and patient satisfaction. This performance advantage stems from physicians' and APPs’ intimate understanding of their patient’s needs, clinical workflows, and care delivery optimization. However, traditional ACO structures often dilute physician and APP governance through complex multi-stakeholder arrangements that compromise clinical decision-making authority.

The Practice Mutual model addresses this challenge by creating a legal structure that ensures physician/APP ownership, governance, and operational control while providing the infrastructure necessary for successful global payment arrangements. This approach combines the clinical expertise that drives superior ACO performance with the financial incentives and operational support required for sustainable growth.

1. Defining the Practice Mutual Model

Core Definition
A Practice Mutual is a Physician and/or APP owned and  governed total cost of care entity that accepts global payments for defined patient populations while maintaining operational independence through a strategic partnership with a Management Service Organization. Unlike traditional IPAs, which typically focus on contracting and limited capitation, Practice Mutuals assume full financial responsibility for their attributed beneficiaries' total cost of care.

Key Differentiators:

  • Physician/APP Ownership and Governance: Unlike hospital-anchored ACOs or health plan-sponsored models, or private equity-backed models, Practice Mutuals are entirely owned and governed by participating clinicians. This structure ensures that clinical decisions remain physician/APP-driven while financial benefits flow directly to participating providers.

  • Full Global Payment Plans: While IPAs may participate in shared savings or limited capitation arrangements, Practice Mutuals accept total cost of care payments similar to Medicare Advantage plans but with physician/APP governance rather than health plan governance.

  • Operational Independence: Through a strategic MSO partnership, Practice Mutuals maintain operational independence while accessing sophisticated back-office functions, technology platforms, and regulatory compliance support that would be prohibitively expensive for individual practices.

  • Scalable Structure: The model enables rapid scaling across multiple markets and payer relationships while maintaining local physician/APP leadership and clinical autonomy.

Legal Structure and Compliance

The Practice Mutual structure must navigate complex healthcare regulations while maintaining physician/APP ownership and control. Key legal considerations include:

  • Entity Formation: Practice Mutuals typically organize as professional corporations or limited liability companies, or, in this case, an ACO or similar global payment entity, depending on state regulations governing physician/APP ownership of healthcare entities. The structure must ensure compliance with corporate practice of medicine laws while enabling a collective total cost of care payment model. In ACOs or similar entities, CMS has safe harbor provisions or waivers allowing gainsharing savings and beneficiary inducements.

  • Downside Exposure: As full global payment entities, Practice Mutuals must meet state insurance regulations or obtain appropriate licensure for downside exposure activities. This includes maintaining adequate financial reserves, obtaining required bonds or guarantees, and implementing appropriate reinsurance arrangements. In the Kenji/P3 MSO, this is managed by the MSO, and a broker’s commission or equivalent will apply.

  • Anti-Kickback and Stark Law Compliance: The model must structure physician/APP compensation and downside exposure arrangements to comply with federal anti-kickback and physician/APP self-referral laws while maintaining the financial incentives necessary for effective exposure management. Again, this is allowed by the program waivers and safe harbor provisions.

  • Network Contracts: Practice Mutuals require comprehensive contracting arrangements with hospitals, specialists, ancillary providers, and other network participants to ensure coordinated care delivery and appropriate exposure allocation. This work is performed by the MSO or P3/Kenji leadership.

2. Strategic Framework and Benefits

The Clinical Excellence Foundation

Practice Mutuals build on the demonstrated performance advantages of physician/APP-led organizations by creating structures that amplify these benefits. The model emphasizes preventive care, care coordination, and chronic disease management—areas where physician and APP leadership has proven most effective.

The physician/APP-led governance structure ensures that clinical protocols and care pathways are developed by practicing clinicians who understand the practical realities of care delivery. This approach contrasts with hospital-anchored models where administrative priorities may conflict with optimal clinical decision-making.

Financial Alignment and Sustainability

By accepting full financial risk, Practice Mutuals align physician and APP incentives with optimal patient outcomes and cost management. This alignment creates powerful motivations for care innovation and efficiency improvements that benefit patients, physicians/APPs, and the broader healthcare system.

The model enables enhanced physician and APP compensation through several mechanisms:

  • Shared savings from efficient care delivery

  • Quality bonuses for achieving superior clinical outcomes

  • Elimination of administrative overhead and conflicts typical in hospital-employed models

  • Direct ownership benefits from organizational growth and success

Operational Sophistication

The model addresses the operational complexity of global payment arrangements through strategic partnerships that provide necessary infrastructure without compromising physician/APP autonomy. Management Service Organizations offer:

  • Technology Platforms: Advanced analytics, electronic health record integration, and population health management tools.

  • Administrative Services: Claims processing, member services, and regulatory compliance support.

  • Clinical Support: Chronic care management programs, quality reporting, and clinical decision support systems.

  • Financial Management: Actuarial analysis, reserve management, and financial reporting.

3. Implementation Framework

Formation and Governance

The establishment of a Practice Mutual requires careful attention to legal structure, governance framework, and operational design. Key considerations include:

  • Physician/APP Collaboration: Participating physicians and APPs must commit to pooling their clinical expertise, patient populations, and willingness to modify practice patterns to achieve financial and clinical goals. This collaboration extends beyond traditional IPA models to include shared accountability for clinical and financial outcomes.

  • Governance Structure: The model requires clear governance frameworks that ensure physician/APP leadership while enabling effective decision-making. This includes establishing medical leadership roles, clinical committees, and performance accountability mechanisms.

  • Legal Entity Formation: The organization must be established as a legally compliant entity that meets state requirements for physician/APP ownership while enabling global payment activities. This process requires specialized legal expertise in healthcare law and regulatory compliance. P3/Kenji MSO brings leadership in forming this structure here.

  • Network Development: Comprehensive contracting arrangements with hospitals, specialists, and ancillary providers are essential for coordinated care delivery and appropriate risk allocation. All done by the MSO.

Transition to a Total Cost of Care Payment Model

The transition from fee-for-service to a full global payment model requires systematic planning and implementation. The work coincides with advanced negotiations with all payers. This is led by P3/Kenji and in collaboration with the Practice Mutual and state leadership.

  • Payment Model Transition: Moving from fee-for-service reimbursement to full global payment models requires careful planning to ensure financial stability during the transition period. Direct contracting strategy is organized and led by the MSO.

  • Downside Exposure Strategies: Comprehensive exposure management programs must be implemented to predict and manage healthcare costs effectively while ensuring financial stability. Again, led and managed by the MSO, and compensated by a brokerage commission or equivalent.

  • Quality Assurance Programs: Systematic quality assurance and improvement programs are essential for maintaining high standards of care and achieving performance targets. Led by the MSO.

  • Data Management and Analytics: Advanced data systems are required to track performance, identify improvement opportunities, and support evidence-based decision-making. Led by the MSO.
