For nearly a decade after the late-2000s Centers for Medicare & Medicaid Services (CMS) policy changes, work Relative Value Units (RVUs) felt like a stable currency. Many organizations are locked into a specific year – 2008 being a common anchor – not because it was perfect, but because it was predictable. Productivity could be measured, compensation plans could be managed, and economic models could assume relative stability in physician work measurement.
That era is over.
Recent CMS policy decisions – culminating in the 2026 Physician Fee Schedule – signal a philosophical shift in how physician work is valued, adjusted, and used as a policy lever. The takeaway is not that RVUs are broken; it is that they are no longer designed to be static.
CMS Is Revaluing Work on Purpose
In the 2026 Final Rule, CMS finalized an efficiency adjustment to work RVUs for many non–time-based services. Using a five-year Medicare Economic Index productivity lookback, they applied an across-the-board negative-2.5-percent efficiency adjustment, with certain exemptions.
This matters less for the size of the adjustment than for what it represents.
CMS is now openly acknowledging – and acting on – the idea that work RVUs tend to drift upward over time as practice patterns, technology, and workflows become more efficient. Rather than allowing that drift to accumulate silently, CMS is baking assumed efficiency gains directly into work valuation.
That is a fundamental change. RVUs are no longer just a reflection of the work effort surveyed. They are also a policy instrument designed to counter perceived inflation in physician work.
Here is the uncomfortable truth that rarely gets said out loud: this is not a one-time correction. In the 2026 Final Rule commentary, CMS indicated its intent to periodically reassess and reapply efficiency adjustments – potentially on a three-year cycle – rather than treating this as an isolated recalibration. Organizations still treating RVUs as a neutral, stable unit of production are embedding risk into their economic assumptions.
Payment Structure Is Being Used to Shape Behavior
Starting in 2026, CMS implemented two separate conversion factors – one for Qualifying Participants in Advanced Alternative Payment Models (APMs) and one for non-QPs. The mechanics matter less than the direction. CMS is increasingly comfortable using a payment structure to encourage participation in specific models of care.
This means that the relationship between RVUs, dollars, and behavior is becoming more conditional and less uniform. Two physicians generating identical RVUs may no longer represent equivalent economics, depending on participation status and payment pathways. RVUs still matter – but they matter in context.
The evolution of split/shared billing rules reinforces this point. Under current CMS guidance, the “substantive portion” requirement varies by service category. For non-critical-care evaluation and management (E&M) services, the substantive portion can be defined by either more than 50 percent of total time or a substantive portion of the medical decision-making. For critical care and certain prolonged services, only time counts; the billing provider must perform more than half the total time spent on the encounter.
This is not a one-off technical adjustment. It is an example of how CMS is increasingly tying work attribution to operational detail. RVUs are no longer just assigned; they must be earned under more explicit, auditable rules. For organizations, this means physician productivity measurement is increasingly dependent on internal workflows, documentation practices, and compliance infrastructure.
What This Means for Economic Modeling
Taken together, these changes point to a clear conclusion: the resource-based relative value scale (RBRVS) is being actively managed, not passively maintained.
That does not mean organizations must abandon RVUs. It does mean that treating a legacy RVU schedule as a timeless standard is increasingly risky, particularly in transaction settings where comparability, sustainability, and forward-looking assumptions matter.
Consider the mathematics. A specialty practice with 15 physicians generating 75,000 total work RVUs annually at $55 per wRVU above the threshold represents approximately $4.125 million in compensation cost. Apply the 2.5-percent efficiency adjustment and that same actual work now measures as 73,125 wRVUs—a shift that can affect Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) by six figures without any change in clinical activity.[1]
Small RVU adjustments have outsized effects in physician-heavy specialties. Productivity comparisons across platforms may reflect benchmark drift, rather than performance differences. Forecasts built on “stable” RVU assumptions are more fragile than they appear.
The strategic risk is not that RVUs are wrong; it is that they are no longer neutral.
The Emerging Best Practice
Organizations do not need to react by constantly rewriting compensation plans. What they do need is clarity. Best practice is shifting toward explicit governance around which RVU schedule is used and why, parallel analyses that quantify sensitivity to RVU updates, and clear disclosure in economic models about how productivity is measured and how it would change under current CMS assumptions. This reframes RVUs from a hidden assumption into a managed variable.
I am aware of transaction models that still project five-year physician compensation using 2008 RVUs, without acknowledging the measurement assumption. That approach worked when RVUs were stable. It does not work now.
The question is not whether RVU adjustments will continue; CMS has told us they will. The question is whether economic models and strategic plans account for that reality, or proceed as if stability will somehow return.
A New Normal, Not a Temporary Phase
The most important insight may be this: the post-2021 environment does not look like a temporary disruption. It looks like the new normal.
CMS is signaling that physician work valuation will continue to be adjusted, refined, and used as a policy tool. They are pushing toward time-based valuation for more service categories, expanding site-neutral payment to narrow practice expense variations, and questioning whether the RUC process adequately accounts for technology-driven efficiency gains.
Stability may still exist, but it will be constructed, not assumed.
For those of us who build economic models around physician productivity, the strategic question is no longer “which RVU year is right?” It is: “do we understand how sensitive our conclusions are to the way physicians work is being redefined?”
That is a more strategic question. It is also more durable.
