Total RVU is the sum of a service’s work RVU, selected practice expense RVU, and malpractice RVU before geographic adjustment. A Medicare payment estimate is a later step: the three components are adjusted with their matching GPCI values and the adjusted total is multiplied by the applicable conversion factor.
Keeping those stages separate prevents a common error in RVU discussions: calling the final dollar estimate “total RVU.” The number before the conversion factor is an adjusted RVU total; the number after the conversion factor is a Medicare payment estimate.
The Three Stages of the Formula
Total RVU =
Work RVU + Selected PE RVU + MP RVU
Adjusted total RVU =
(Work RVU × Work GPCI)
+ (Selected PE RVU × PE GPCI)
+ (MP RVU × MP GPCI)
Medicare payment estimate =
Adjusted total RVU × Conversion FactorThe selected PE RVU is either the facility or non-facility value that matches the applicable CMS payment context. Both PE values are not added together.
The RVU Components
| Component | What it represents | GPCI applied |
|---|---|---|
| Work RVU | Physician time, skill, mental effort, and judgment | Work GPCI |
| Practice expense RVU | Staff, supplies, equipment, and overhead assumptions | PE GPCI |
| Malpractice RVU | Professional liability cost assumptions | MP GPCI |
Work RVU is the component most often used in physician productivity and compensation plans. Medicare payment modeling uses work, PE, and MP together. A CPT/RVU calculator should therefore show the components separately rather than present one unexplained number.
Selecting the PE Setting
CMS publishes separate facility and non-facility PE values for many services. The applicable column depends on the payment setting and claim context. It should not be selected only because a hospital or ambulatory surgical center is involved.
| Setting | Calculation input | Why the result can change |
|---|---|---|
| Non-facility | Non-facility PE RVU | The physician practice generally carries more of the modeled resource burden |
| Facility | Facility PE RVU | The applicable facility column generally reflects a different resource-cost assumption |
For the same code, the work RVU may remain unchanged while the selected PE RVU changes. Any total-RVU result without a setting label is difficult to reproduce.
Applying GPCI Component by Component
GPCI values are locality-specific adjustments. Work GPCI applies only to work RVU, PE GPCI applies only to the selected PE RVU, and MP GPCI applies only to MP RVU. A value above 1.000 increases that component’s contribution; a value below 1.000 decreases it.
For a national baseline comparison, using 1.000 for all three GPCI inputs reduces the calculation to the unadjusted sum. A locality-specific estimate should identify the exact CMS payment locality rather than use an unlabeled state average.
Use the GPCI Calculator when the purpose is to compare localities. Keep the CPT code, setting, participant status, and data year fixed so the difference can be attributed to geography.
2026 Conversion Factors
Beginning in calendar year 2026, CMS uses separate conversion factors: USD 33.4009 for non-qualifying APM participants (non-QP) and USD 33.5675 for qualifying APM participants (QP). The applicable rate is a year-specific payment input, not a physician compensation rate. See the CY 2026 Medicare Physician Fee Schedule final rule for the finalized figures.
The QPP vs. non-QP calculator can isolate the conversion-factor difference while keeping the code, setting, and locality unchanged.
Worked Example
The following values are illustrative and are not the CMS-published values for a particular CPT code:
- Work RVU: 1.50
- Non-facility PE RVU: 1.20
- MP RVU: 0.10
- Work GPCI: 1.05; PE GPCI: 1.10; MP GPCI: 0.90
- Conversion factor: USD 33.4009 for the illustrative 2026 non-QP example
Step 1: adjust each component.
Work: 1.50 × 1.05 = 1.575
PE: 1.20 × 1.10 = 1.320
MP: 0.10 × 0.90 = 0.090Step 2: add the adjusted components.
Adjusted total RVU = 1.575 + 1.320 + 0.090
= 2.985Step 3: apply the conversion factor.
Medicare payment estimate =
2.985 × $33.4009
= $99.7016865
≈ $99.70The displayed amount is rounded to cents. It is an illustrative Medicare payment estimate, not a guaranteed claim payment.

Total RVU and wRVU Compensation
| Total RVU and Medicare payment | Work RVU compensation | |
|---|---|---|
| Purpose | Models Medicare payment for a service | Measures credited physician production |
| Inputs | Work, PE, MP, GPCI, setting, and conversion factor | Credited work RVU and contract terms |
| Dollar rate | CMS conversion factor | Contract-negotiated dollars per wRVU |
| Authority | CMS MPFS rules and files | The written employment or compensation agreement |
A compensation plan that pays a contract-defined rate per wRVU applies a private rate to work RVU. It does not establish what Medicare pays for the same code, because Medicare payment also includes PE and MP and uses geographic adjustment.
Inputs Required for an Auditable Result
- CPT or HCPCS code and the source data year
- Facility or non-facility setting
- Exact CMS payment locality and its work, PE, and MP GPCI values
- QP or non-QP participant status for the applicable year
- Conversion factor year and displayed precision
When comparing two scenarios, change one variable at a time. For example, keep the CPT code, setting, and participant status fixed when comparing localities. The RVU Calculator handles the code-level payment workflow, while the Salary Calculator is for contract-based compensation assumptions.
Where This Formula Does Not Apply
The formula describes Medicare payment modeling under the selected MPFS assumptions. It does not automatically determine commercial-payer allowed amounts, physician compensation, practice profitability, or final claim collections. Modifiers, bundling, multiple-procedure rules, payer edits, and other claim-specific factors can change the final remittance amount.
