Unrealized Promises of Value-Based Care

1. The concrete operational programs, not the philosophy, are what actually bend the cost curve, and each one requires deliberate design and sustained investment. Coastal Carolina's success was not accidental, and Nuckolls was explicit about this. They built four interconnected programmatic pillars: expanded access (urgent care with broader testing capability, same-day appointments, a 24-hour triage line that could book next-day physician appointments to prevent avoidable ED visits, a high-acuity extended care clinic, and a "call us first" messaging campaign embedded in every annual wellness visit); chronic care management (embedded, not centralized, in each primary care office, with care managers and physicians working side by side and patients stratified by HCC risk scores above 2, more than one hospitalization, or more than two ED visits per year); primary and palliative care at home (physician and APP home visits for high-risk and end-of-life patients, offered as an alternative to hospitalization and hospice for appropriate patients); and disciplined quality management (monthly unblinded reporting by provider and clinic, direct compensation linkage, standing nursing protocols for routine referrals and vaccinations, and self-defined quality targets beyond what the program required). Each program carried a real cost: The home program, the extended care clinic, and the longer appointment times all ran at or near break-even on a fee-for-service basis. The economic justification was always the shared savings those programs generated, which made the structural dependence on the benchmark a genuine vulnerability.

2. Specialist alignment is underutilized and underappreciated, and multispecialty groups have a structural advantage that pure primary care ACOs cannot replicate. One of the most practically instructive sections of the presentation was Nuckolls' walk through exactly how Coastal Carolina engaged each of their specialty departments in reducing total cost of care, with concrete examples that went far beyond generic "care coordination" language. Rheumatology helped manage high-cost Part B drug spend, ensuring biologics were used on the right patients, that bisphosphonates were prescribed to everyone with an osteoporosis diagnosis who qualified, and that expensive new bone health drugs like Evenity were applied with appropriate selectivity. Cardiology set up principal care management for congestive heart failure patients, created a referral requirement for PCSK9 inhibitors to prevent direct primary care ordering, and accepted a flat reading fee for nuclear medicine studies that removed the fee-for-service incentive for volume. Gastroenterology maintained office-based and ASC-based colonoscopy rather than shifting to hospital outpatient department billing, a decision that saved approximately 50% per procedure compared to the competitor model. Psychiatry monitored expensive treatments like Spravato® against evidence-based alternatives like IV ketamine. The specialist compensation model (specialists receiving approximately two-thirds of primary care shared savings distributions) created real alignment without requiring perfect attribution. For health systems evaluating whether specialists belong in value-based care programs, Coastal Carolina's experience is a direct rebuttal to the conventional wisdom that ACOs are primarily a primary care exercise.

3. The rebasing problem is the original design flaw of the Medicare Shared Savings Program, and it is actively preventing organizations that succeed from continuing to succeed. The central policy argument of the presentation deserves careful attention, because it is not a complaint about the difficulty of value-based care; it is a structural critique of how the MSSP was designed. When an ACO reduces costs, its benchmark resets downward, meaning future savings must be measured against an already-lowered baseline. For Coastal Carolina, 13 years of disciplined care transformation produced a benchmark so compressed that their effective share of savings fell to 3.75%, barely enough to cover the cost of running the programs that generated the savings in the first place. The perversity of the design is that the organizations most penalized by rebasing are precisely those that have done the most to transform care delivery. Nuckolls argued that this structural flaw is the primary reason large health systems remain cautiously in value-based care rather than committing fully: The CFO math doesn't support going all-in when success guarantees a lower future reward. His policy ask—raising the prior savings adjustment from 5% to something closer to 10–15%—is modest by comparison to what Medicare Advantage plans retain, and represents the minimum threshold at which the economics of sustained program investment become viable for independent medical groups. Until the Centers for Medicare & Medicaid Services (CMS) addresses this, the lesson for other organizations is to manage carefully into the program rather than restructure care delivery in ways that become unsustainable when the benchmark resets.

4. Cost transparency at the individual provider level, tied directly to compensation, is the mechanism that converts abstract quality goals into physician behavior change. Coastal Carolina's quality and cost management approach offers a replicable accountability framework. Every month, each physician received unblinded performance data showing their personal results on every tracked quality measure, alongside their department and clinic peers. Every quarter, they received a risk-adjusted cost report showing total truncated Medicare spend for their attributed patient panel, allowing direct comparison across providers with different patient complexity profiles. The 20 most expensive patients on each physician's panel were regularly reviewed in dialogue: Was this patient in care management? Could palliative care have been appropriate? Was there a different intervention at an earlier stage that might have changed the trajectory? Critically, both the quality metrics and the cost performance were woven directly into the compensation formula, not as a parallel incentive program but as a core component of how physician income was calculated. The competitive dynamic across clinics added another layer: Physicians could see not only their own performance but how their small group compared to others within the organization. As one attendee noted in the Q&A, physicians who might resist abstract conversations about cost find it considerably harder to dismiss data showing their own panel performing above the average cost of their colleagues. The combination of transparency, peer comparison, and direct compensation linkage is what Nuckolls described as the "secret sauce", and it requires organizational willingness to design compensation systems that can be adjusted relatively quickly as priorities shift.

5. Going all-in on value-based care breaks the fee-for-service model, and the organizations that understand this risk before committing are better positioned than those who discover it mid-journey. Perhaps the most sobering reflection in the presentation was Nuckolls' candid acknowledgment that Coastal Carolina's transformation came with a real cost to their fee-for-service economics that they cannot easily reverse. Panel sizes contracted as physicians spent more time per patient. Appointment lengths increased. Programs were added that generated clinical value but not billing revenue. The extended care clinic, the home-based program, and the longer chronic disease management visits all ran on the assumption that shared savings would subsidize the economics that fee-for-service could not support. Now, as savings compress, the group faces a genuine dilemma: Revert toward higher volume, shorter visits, and program elimination—and risk watching hospitalizations and ED visits climb back toward pre-intervention levels against a benchmark that has already been reset to reflect the savings they generated—or find another payment vehicle that can support the care model they built. The consultant who advised them in 2012 told them not to break their fee-for-service system; in hindsight, Nuckolls acknowledged that advice had some wisdom, even though it also meant foregoing the clinical outcomes they achieved. The practical lesson for organizations considering serious value-based care commitment is not to avoid it but to enter it with eyes open about the structural dependency it creates, to build financial reserves during high-savings years that can sustain programs when benchmarks compress, and to maintain active options—Medicare Advantage contracts, ACO REACH participation, or MSSP reentry with favorable benchmark years—so that the care model never becomes entirely hostage to any single payment vehicle.
