Interoperability Standards Advisory
Interoperability Is Finally Getting Useful.
And That Changes the Game for ACOs.
Let’s start with something most ACO leaders will recognize immediately, even if it’s not always said out loud.
You don’t really have a data problem. You have a timing problem.
There is no shortage of data in healthcare. If anything, there is an overwhelming amount of it—spread across EHRs, claims systems, care management platforms, and payer portals. Entire teams exist just to reconcile, validate, and interpret it. And yet, despite all of that effort, the same frustration persists: the information you need to influence a decision often arrives just after that decision has already been made.
That has been the quiet constraint on value-based care for years. Not access, but timing. Not availability, but usability.
So when the 2026 Interoperability Standards Advisory (ISA) is released, it would be easy to skim it, recognize familiar terms like FHIR®, USCDI, and prior authorization standards, and move on. On the surface, it reads like another incremental step in a long series of interoperability updates. But if you look more closely, something more important is happening. The focus is shifting from whether data can move to whether it can actually be used in the moment care is being delivered.
We Solved for Exchange. We Did Not Solve for Action.
For the better part of the last decade, interoperability has been framed as a connectivity problem. Could systems talk to each other? Could information be transmitted from one organization to another? That was a necessary hurdle, and in many ways, the industry has made real progress.
But somewhere along the way, we blurred the line between data exchange and decision-making.
If a discharge summary arrives days after a patient has transitioned to another setting, the system technically worked—but the opportunity to influence care was already gone. If prior authorization requirements are accessible but buried in disconnected workflows, the information exists without actually shaping clinical decisions. These are not edge cases. They are everyday realities.
The 2026 ISA reflects a growing recognition that interoperability only creates value when it changes what happens next. Movement alone is not enough. Timing, context, and usability are what determine whether data has impact.
Continuity Is Becoming Real, Not Theoretical
One of the more meaningful shifts in the ISA is the continued maturation of FHIR-based exchange frameworks, including Patient Access, Provider Access, and Payer-to-Payer data sharing. None of these are entirely new, but their increasing adoption and alignment begin to close a gap that has long existed for ACOs: the lack of a consistent, longitudinal view of the patient.
In practical terms, this is where interoperability starts to matter operationally. When patient information follows individuals across providers, care settings, and coverage transitions, attribution becomes more accurate, risk stratification becomes more precise, and care gaps can be identified earlier—before they escalate into higher-cost interventions.
This is not about having more data. It is about having a version of the data that actually holds together over time. For organizations managing populations, that continuity is the difference between reacting to events and anticipating them.
Prior Authorization Is Moving Into the Clinical Workflow
Another important signal within the ISA is the evolution of prior authorization standards, including Coverage Requirements Discovery, Documentation Templates and Rules, and Prior Authorization Support. Historically, prior authorization has existed outside the clinical workflow, creating friction between decision-making and approval processes.
What these standards suggest is a gradual shift toward integrating those requirements directly into the point of care. Instead of being a downstream administrative hurdle, prior authorization can begin to function as part of the decision-making process itself.
When clinicians have clearer visibility into coverage expectations at the time decisions are being made, several things happen. Delays decrease, rework is reduced, and alignment between clinical intent and payer requirements improves. For ACOs, that alignment translates into more predictable utilization patterns and fewer disruptions in care delivery.
This is not simply about efficiency. It changes how decisions are made and how consistently they can be executed across a network.
We Are Expanding What It Means to Understand a Patient
The continued evolution of the United States Core Data for Interoperability is another signal worth paying attention to, particularly as it expands to include elements such as social determinants of health, care team insights, and patient goals.
This reflects a broader shift in how healthcare defines “complete” information. A patient’s clinical profile alone does not fully explain their outcomes. Factors like transportation, housing stability, and access to support systems often play just as significant a role in whether care plans succeed.
For ACOs, incorporating this broader context into data infrastructure enables more targeted interventions. It allows organizations to identify not just who is at risk, but why—and to design responses that address those underlying drivers rather than just the symptoms.
Quality Measurement Is Becoming Less Retrospective
Quality measurement has traditionally been a backward-looking exercise. Reports arrive months after care has been delivered, leaving organizations to analyze what happened rather than influence what is happening.
The ISA’s emphasis on digital quality measurement represents a continued move away from that model. As quality data becomes more computable and more continuously available, ACOs gain the ability to monitor performance in near real time and adjust strategies accordingly.
This shift has meaningful implications. It allows organizations to intervene earlier, refine care pathways during the performance year, and reduce the lag between insight and action. Over time, that ability to adapt in the moment becomes a competitive advantage.
Why This Shift Is Happening Now
None of these developments exist in isolation, and none of them are entirely new. What is different is the context in which they are being implemented.
Value-based care has reached a level of maturity where the limitations of existing infrastructure are no longer sustainable. ACOs are being held accountable for outcomes, cost trends, and coordination across environments that still operate with varying levels of connectivity and consistency.
At a certain point, expectations outpace infrastructure. When that happens, the system either adjusts or begins to break under its own complexity.
The 2026 ISA reflects an adjustment. It is not a single breakthrough, but a coordinated movement toward making interoperability operationally relevant rather than technically possible.
What This Means for How Organizations Operate
As interoperability becomes more actionable, it will begin to change how ACOs are expected to function on a day-to-day basis. The conversation will move away from whether data is available and toward how effectively it is used.
This has implications across multiple dimensions of the organization. Decision-making timelines will compress as information becomes available earlier. Clinical and administrative workflows will need to align more closely as processes become more integrated. Teams will be expected to act on insight more quickly and with greater consistency.
Perhaps most importantly, the margin for operating with fragmented or delayed information will continue to shrink. As the infrastructure improves, so do the expectations tied to it.
Where AaNeel Comes In
Even as standards evolve, the work of translating data into action does not happen automatically. Interoperability creates the conditions for better decision-making, but it does not guarantee it.
This is where AaNeel plays a critical role.
By aligning data across sources, structuring it in ways that support decision-making, and embedding it into operational workflows, AaNeel helps organizations move beyond simply having access to information. The focus shifts to using that information in real time to influence outcomes, manage risk, and coordinate care more effectively.
In an environment where timing and usability matter as much as access, that distinction becomes increasingly important.
The Bigger Shift
Interoperability is no longer just about connecting systems. It is about closing the gap between insight and action.
As that gap narrows, ACOs gain the ability to operate with greater clarity, respond more quickly to emerging needs, and manage populations with a level of precision that was previously difficult to achieve.
That is the real signal behind the 2026 ISA. Not just that data can move, but that it can begin to matter in the moment it is needed.
