An RVU, or relative value unit, is a weighting used in the Medicare Physician Fee Schedule (MPFS). It is not a dollar amount, a charge, or a billing code. The number becomes useful for payment modeling only after the applicable RVU components are adjusted for geography and multiplied by the correct conversion factor.
The same term is used in several different workflows. A coder may be reviewing the MPFS, an administrator may be measuring production, and a physician may be reviewing a compensation plan. Those workflows use related data, but they do not answer the same question.
What an RVU Measures
CMS uses relative values to compare the resources associated with different CPT and HCPCS services. A service with 2.00 work RVUs represents roughly twice the physician-work weight of a service with 1.00 work RVU within the valuation system. Neither number is a fee by itself.
A reliable review keeps four steps separate:
- Select the code: use the code supported by the service and its documentation.
- Read the components: identify work, practice expense, and malpractice RVUs for the applicable year.
- Apply locality: use the relevant work, PE, and MP GPCI values.
- Interpret the output: use the Medicare conversion factor for payment modeling or the written contract rate for compensation modeling.
Skipping directly from a work RVU to a dollar amount is the source of many incorrect comparisons. A work RVU can be a compensation input without being a Medicare payment input.
The Three RVU Components
For a Medicare payment estimate, the three principal components are reviewed separately:
| Component | What it represents | Common use |
|---|---|---|
| Work RVU (wRVU) | Physician time, technical skill, mental effort, and judgment | Productivity measurement and many compensation plans |
| Practice expense RVU (PE RVU) | Clinical labor, supplies, equipment, and practice overhead assumptions | Medicare payment modeling; the value may differ by setting |
| Malpractice RVU (MP RVU) | Professional liability cost assigned to the service | Medicare payment modeling with the MP GPCI |
Physician compensation plans often use work RVU alone. Medicare payment modeling uses all three components, with a separate GPCI applied to each component before the conversion factor is used.
How RVUs Become a Medicare Payment Estimate
The first calculation is the geographically adjusted total RVU. The second calculation converts that adjusted total into a Medicare payment estimate:
Adjusted total RVU =
(Work RVU × Work GPCI)
+ (Selected PE RVU × PE GPCI)
+ (MP RVU × MP GPCI)
Medicare payment estimate =
Adjusted total RVU × Conversion FactorThe GPCI values are component-specific. Work GPCI adjusts work RVU, PE GPCI adjusts the selected practice expense RVU, and MP GPCI adjusts malpractice RVU. A single blended locality multiplier is not an equivalent substitute.
For a code-level result, use the RVU Calculator. When the question is how the same code changes across localities, use the GPCI Calculator and keep the CPT code and setting fixed.
2026 Conversion Factors
For calendar year 2026, CMS uses separate conversion factors for qualifying APM participants and non-qualifying participants. The finalized figures are documented in the CY 2026 Medicare Physician Fee Schedule final rule:
| Participant status | 2026 conversion factor | Change from 2025 (USD 32.35) |
|---|---|---|
| Qualifying APM participant (QP) | USD 33.5675 | +3.77% |
| Non-qualifying APM participant (non-QP) | USD 33.4009 | +3.26% |
These are year-specific payment inputs, not permanent rates. CMS also finalized a 2026 efficiency adjustment that affects work RVU inputs for many services. A result should therefore carry its data year and participant-status assumption.
Facility and Non-Facility Practice Expense
Many codes have separate facility and non-facility PE RVU values. The correct choice depends on the applicable CMS payment context and place of service; it should not be selected solely because a hospital or ambulatory surgical center is involved.
- Non-facility PE RVU: generally reflects a professional service for which the physician practice bears more of the staff, equipment, supplies, and space costs.
- Facility PE RVU: generally reflects the CMS facility column used for the applicable professional-claim context when the facility bears more of those resource costs.
Work RVU and MP RVU commonly remain the same across the two columns for a code, while the selected PE RVU changes. The setting must be recorded with any comparison because it can change the adjusted total RVU and the resulting payment estimate.
The Practice Expense RVU explanation covers the setting distinction in more detail.
Medicare Payment and Physician Compensation Are Different
A Medicare payment estimate asks what the MPFS formula produces for a code, locality, setting, participant status, and data year. A compensation model asks what an employer or group pays under a written agreement. Compensation may use credited work RVUs, a threshold, a dollars-per-wRVU rate, a base salary, or other contract terms.
| Medicare payment estimate | wRVU compensation model | |
|---|---|---|
| RVU inputs | Work, PE, and MP RVUs | Usually work RVU only |
| Geography | Work, PE, and MP GPCI values | Contract-specific |
| Dollar rate | CMS conversion factor | Negotiated dollars per wRVU |
Neither rate predicts the other. A compensation rate such as USD 45 per credited work RVU is an illustrative contract input, while the Medicare conversion factor is applied to geographically adjusted total RVU.
A Practical RVU Review
- Confirm the CPT or HCPCS code through the appropriate coding and documentation process.
- Record the MPFS data year and the selected facility or non-facility setting.
- Read the work, PE, and MP RVU values and the locality-specific GPCI values.
- Record whether the payment scenario uses the QP or non-QP 2026 conversion factor.
- Run the result in the RVU Calculator and keep the assumptions with the copied result.
For a step-by-step numeric example, see Medicare Payment Calculation Example. For compensation questions, compare credited work RVUs with the written agreement rather than substituting the Medicare conversion factor.
Frequently Asked Questions
Is one work RVU equal to a fixed number of dollars?
No. A work RVU is a relative physician-work weight. A Medicare payment estimate requires PE and MP RVUs, GPCI values, and the applicable conversion factor.
Why can the same CPT code produce different Medicare estimates?
The selected setting, locality-specific GPCI values, participant status, and annual conversion factor can change the estimate even when the code is unchanged.
Can I use the Medicare conversion factor in a compensation contract?
Only if the written agreement expressly says so. Most wRVU compensation plans use a contract-defined dollars-per-wRVU rate instead.
