The conversation about value-based care in the United States has centered almost entirely on the contract between payers and health systems. That framing misses the problem. The moment a payer converts a health system to shared savings or risk-bearing arrangements, it has accomplished something real at one level of the economic architecture. What it has not done is change how the physician at the end of that system gets paid. Those are two separate agreements, governed by two separate sets of rules, and almost always moving at two separate speeds.
The result is a structural disconnect that sits quietly underneath most VBC implementation failures. Clinicians are asked to change behavior in service of outcomes they were never compensated to produce, under contracts they never saw, tied to shared savings pools they may never receive. Understanding why that gap exists, how it is constructed, and what closing it actually requires is the work this piece attempts to do.
1. What the Evidence Shows
In January 2022, researchers from RAND and Harvard published a landmark study in JAMA Health Forum examining physician compensation arrangements across 580 US physician organizations. The findings were not subtle. Despite years of payer investment in value-based contracting, only 9% of primary care physician compensation and 5% of specialist compensation was tied to value-based metrics. The overwhelming majority of physician pay remained driven by volume: productivity targets, RVU generation, and coverage obligations.
The finding is striking not because it is surprising to practitioners in this space, but because it quantifies a gap that most senior health system leaders already understand intuitively. The payer has moved. The system contract has moved. The physician's employment agreement has not. For those designing, selling, or implementing VBC programs, this asymmetry is the central operational challenge, and it deserves more analytical attention than it typically gets.
A health system can earn a shared savings distribution and have zero obligation to pass any of it to the clinicians whose practice patterns generated it.
The study surveyed organizations ranging from large integrated delivery networks to independent physician groups. Across all of them, the dominant compensation driver remained work relative value units (wRVUs), fixed salary tied to coverage obligations, or some combination of the two. Value metrics, where they appeared at all, were typically additive bonuses rather than structural redesigns of the base compensation model.
2. Two Separate Contracts
The architecture of the problem is worth tracing precisely. A payer and a health system negotiate a value-based arrangement, which could be an ACO, a shared savings agreement, a bundled payment arrangement, or a capitated product. That contract defines the unit of accountability (population, episode, attributed panel), the performance targets, and the financial reconciliation methodology. It is a business-to-business agreement between two organizations.
The physician's employment agreement is a completely separate document. It defines base pay, productivity expectations, bonus eligibility, and term. It is governed by different legal frameworks, different internal approval processes, and different organizational incentives. The general counsel reviewing the payer contract is not the same team reviewing physician employment agreements. The CFO modeling the VBC upside is not the same team that sets the physician compensation plan.
When a health system earns shared savings, those funds enter the organization as operating revenue. Their disposition is a capital allocation decision, not an automatic physician distribution. The organization may reinvest those dollars in infrastructure, use them to offset operating losses in other service lines, or hold them as reserve. This is not malfeasance. It is how organizations manage capital. But the effect is that a physician may have driven every meaningful quality metric that generated the upside without ever seeing a dollar of it, or knowing the upside existed.
This structural reality creates a fundamental misalignment. Health systems genuinely working toward value often express frustration that their clinical workforce "isn't aligned." The more honest framing is that the workforce is precisely aligned to the incentives they were given, which are predominantly volume-based. Expecting value-oriented behavior without redesigning the compensation signal is not an alignment problem. It is an incentive design problem.
3. The Revenue Architecture Underneath
To understand why compensation redesign is difficult, it helps to understand how professional and technical revenue flow through a health system, because the two streams operate under different rules and create different leverage points for incentive alignment.
In inpatient care, admitted encounters typically bundle the technical component into the hospital's DRG payment. The facility bill covers nursing, pharmacy, imaging, and ancillary services. The physician's professional fee is billed separately under the physician's NPI, subject to the physician group's payer contracts. A hospitalist, attending physician, or consulting specialist may be billing independently from the facility, but their compensation is set by their employment agreement with the system, not by what the system earns on the DRG.
In outpatient care, professional and technical components are billed separately and tied to site-of-service fee schedules. A cardiologist performing a stress test in a hospital-owned outpatient department generates both a professional fee (billed by the physician group) and a technical fee (billed by the facility). The physician's income from that encounter is their wRVU credit for the professional work. The technical revenue flows to the facility and does not appear in the physician's compensation calculation unless the employment agreement explicitly shares technical revenue, which it typically does not.
This architecture has a consequential downstream effect: a physician who shifts practice patterns to reduce unnecessary imaging, shorten length of stay, or avoid preventable admissions may simultaneously reduce their own wRVU production and the technical revenue of the facility. Under a pure volume-based compensation model, value-oriented behavior is financially penalized at the individual level, even when it generates system-level savings that the payer rewards through the VBC contract.
4. Mapping the Compensation Models
Physician compensation in US health systems is not monolithic. Across a single system, a cardiologist, a hospitalist, and an imaging specialist may each be compensated under entirely different structures, despite operating under the same payer contract and the same VBC performance targets. The table below maps the 17 primary compensation models in use, with their professional and technical revenue implications and alignment orientation.
The practical implication is significant. A health system can have a sophisticated ACO REACH or shared savings program at the payer level and simultaneously have 80% of its employed physicians on wRVU-based contracts with a quality bonus that represents less than 5% of total potential compensation. Those two facts coexist routinely. The payer sees a committed value-based partner. The physician sees a productivity target and a call schedule.
5. The Foundational Framework: Quinn's 8 Payment Methods
Kevin Quinn's 2015 paper, "The 8 Basic Payment Methods in Health Care," published in Annals of Internal Medicine, remains one of the most useful frameworks for understanding why physician compensation is structured the way it is. Quinn identifies eight fundamental payment building blocks and shows how every reimbursement model in American healthcare is a derivative of one or more of them. Understanding these building blocks clarifies why redesigning physician compensation is harder than it appears from the payer contract level.
The critical insight Quinn's framework surfaces is that payer-level VBC models, which operate on shared savings, capitation, or global budget logic, have a natural tension with the dominant physician compensation method, which is fee-for-service via wRVUs. Every time a payer shifts a health system toward methods 4, 6, 7, or 8, they are asking the system to perform in a way that conflicts with the internal incentive signal the system is sending its physicians through methods 1, 2, and 5.
Payment reforms including ACOs, bundled payments, patient-centered medical homes, and shared savings extend Quinn's models by linking performance to population outcomes. But physician compensation has largely lagged in adopting corresponding structures. The redesign requires rewriting employment agreements, recalculating bonus thresholds, creating new governance mechanisms for shared savings distribution, and in many cases persuading physicians that a model they did not negotiate for is now their professional context. None of that happens automatically from a payer contract.
6. The Compliance Architecture That Makes Redesign Hard
It is worth naming the regulatory constraints on physician compensation design directly, because they are sometimes cited as an excuse for inaction when they are more accurately described as a design parameter. The constraints are real. They do not make alignment impossible. They make it expensive and slow.
The Anti-Kickback Statute prohibits offering remuneration to induce or reward referrals of federally funded business. The Stark Law prohibits a physician from referring Medicare or Medicaid patients to an entity with which the physician has a financial relationship, with exceptions. Fee-splitting prohibitions vary by state but restrict certain revenue-sharing arrangements between healthcare entities. Designing a physician compensation plan that ties pay to downstream volume or referral patterns without satisfying a recognized safe harbor creates material legal exposure.
Gainsharing arrangements, which are one of the few mechanisms that directly connect physician compensation to cost reduction, require a structure that satisfies the OIG's gainsharing advisory opinions. Global budget and capitation arrangements that put physicians in downside risk require careful analysis under Stark and state insurance licensure frameworks. Even straightforward shared savings distribution to employed physicians requires the employment agreement to include explicit pass-through provisions, which most standard templates do not.
Risk adjustment activities in VBC arrangements require documentation that reflects active clinical monitoring, evaluation, and treatment planning for any diagnosis the system is prospectively coding. Corporate Practice of Medicine rules, which vary significantly by state, define who can employ physicians and under what governance structures. AI-assisted clinical decision support tools that influence reimbursement are subject to evolving governance frameworks under CMS and OIG guidance.
The compliance architecture does not prevent physician compensation from being redesigned toward value. It requires that the redesign be deliberate, legally structured, and supported by governance infrastructure that most health systems have not built. That is the actual work.
7. What Alignment Actually Requires
Health systems that are serious about closing the compensation cascade have a fairly clear set of requirements, though executing against them is non-trivial.
The first requirement is transparency at the physician level. Most employed physicians have no line of sight to their system's VBC performance, what the system earned or lost in shared savings last year, or how their clinical patterns influenced that outcome. Building that transparency does not require restructuring every employment agreement. It requires building the reporting infrastructure and making a deliberate choice to share the information. Systems that have done this consistently report improved clinical engagement with quality and cost metrics even before any compensation change.
The second requirement is an explicit pass-through mechanism. If a health system wants to distribute shared savings to physicians, the employment agreement has to authorize it. That requires legal review, renegotiation in many cases, and board-level governance decisions about how distributions are structured and to whom. Systems using ACO REACH and similar models have been building this infrastructure over the past several years. It is not easy, and the administrative overhead is significant, but the legal framework exists.
The third requirement is compensation plan redesign for new physicians. The most practical path for many large systems is not to renegotiate every existing employment agreement simultaneously, but to build value-aligned structures into new agreements and transition contracts. Over a five-to-ten year horizon, this shifts the compensation culture without requiring a wholesale disruption of the employed medical staff.
The fourth requirement is explicit non-clinical incentives for transformation work. The 17th model in the taxonomy above, non-clinical incentive compensation, is underutilized. Physicians who lead quality improvement programs, deploy AI-assisted care tools, redesign care pathways, or manage population health protocols are doing work that directly enables VBC performance. Compensating that work with project-based stipends or discretionary bonuses gives the system a mechanism to recognize and retain the clinicians most engaged in the transformation, without restructuring the broader compensation architecture.
The fifth requirement is organizational honesty about the misalignment. Systems that have the most success with physician alignment are usually the ones that stopped pretending the misalignment did not exist. Calling a system value-based when the physician compensation plan is 95% wRVU-driven creates institutional dissonance that erodes trust. Naming the gap, explaining the timeline for closing it, and showing physicians that the system is investing in the infrastructure to make it real is a precondition for the behavioral change that VBC programs require.
The future of physician alignment will not be decided by payer contracts alone. It depends on how health systems choose to translate value into compensation, and how transparently they connect clinicians to the outcomes they produce.
Until those incentives are redesigned, physicians will continue operating in two economies simultaneously: one funded by value at the payer-system interface, another rewarded by volume at the system-physician interface. Payer contracts cannot close that gap. The health system has to choose to close it.
