Calculating RVUs accurately is essential for understanding Medicare reimbursement and tracking physician productivity. The process involves combining three RVU components, adjusting for geographic location, and applying the Medicare Conversion Factor. Here's how to calculate both total RVUs and the resulting payment amount.
The Complete RVU Calculation Formula
Total RVU = (Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)
Payment = Total RVU × Conversion Factor
Each CPT code has three RVU components that must be adjusted for your geographic location before calculating total payment. The Geographic Practice Cost Index (GPCI) accounts for regional variations in practice costs, with separate GPCI values for work, practice expense, and malpractice insurance.
Step-by-Step RVU Calculation Process
Step 1: Look Up RVU Components
Find the Work RVU, Practice Expense RVU, and Malpractice RVU values for your CPT code in the annual Medicare Physician Fee Schedule published by CMS. For example, CPT 99213 (established patient office visit) has Work RVU 1.30, PE RVU 1.13, and MP RVU 0.10.
Step 2: Find Your GPCI Values
Locate your locality's GPCI values from the CMS GPCI file. Geographic areas are assigned specific GPCI multipliers for each RVU component. For instance, Manhattan (locality 00) has Work GPCI 1.094, PE GPCI 1.316, and MP GPCI 1.657, reflecting higher costs. Rural Kansas (locality 04) has Work GPCI 0.988, PE GPCI 0.889, and MP GPCI 0.527, reflecting lower regional costs.
Step 3: Calculate Geographically Adjusted RVUs
Multiply each RVU component by its corresponding GPCI value, then sum the results. Using Manhattan GPCI values for CPT 99213: (1.30 × 1.094) + (1.13 × 1.316) + (0.10 × 1.657) = 1.422 + 1.487 + 0.166 = 3.075 total RVUs. The same code in rural Kansas yields: (1.30 × 0.988) + (1.13 × 0.889) + (0.10 × 0.527) = 1.284 + 1.005 + 0.053 = 2.342 total RVUs.
Step 4: Apply the Conversion Factor
Multiply total geographically adjusted RVUs by the Medicare Conversion Factor. For 2025, this factor is $33.29 per RVU. Manhattan payment: 3.075 × $33.29 = $102.37. Rural Kansas payment: 2.342 × $33.29 = $77.97. This demonstrates how geographic location significantly impacts reimbursement even for identical services.
Step 5: Apply Modifiers
Adjust for applicable modifiers. Common modifiers include bilateral procedures (modifier 50, typically 150% payment), multiple procedures (modifier 51, reduces subsequent procedures by 50%), assistant surgeon (modifier 80, typically 16% of surgeon payment), and professional component only (modifier 26, varies by procedure). Always verify current modifier payment rules with CMS as they can change annually.
Real-World Calculation Example
Scenario: Office Visit in San Francisco
CPT Code: 99214 (Office visit, established patient, moderate complexity)
RVU Values from CMS Fee Schedule:
- Work RVU: 1.92
- Non-Facility PE RVU: 2.11
- Malpractice RVU: 0.14
San Francisco GPCI Values:
- Work GPCI: 1.059
- PE GPCI: 1.408
- MP GPCI: 0.866
Calculation:
- Work Component: 1.92 × 1.059 = 2.033
- PE Component: 2.11 × 1.408 = 2.971
- MP Component: 0.14 × 0.866 = 0.121
- Total Adjusted RVU: 2.033 + 2.971 + 0.121 = 5.125
- Payment: 5.125 × $33.29 = $170.61
Note: This is the Medicare allowed amount before patient deductibles and coinsurance. Actual payment may vary based on patient coverage and commercial insurance contracts.
How Modifiers Affect RVU Calculations
Modifier 50 (Bilateral Procedure)
Bilateral procedures typically receive 150% payment of the unilateral rate. Calculate RVUs normally, then multiply final payment by 1.5. Some payers require separate line items with modifier 50 on each.
Modifier 51 (Multiple Procedures)
When multiple procedures are performed in the same session, rank them by RVU value. The highest-valued procedure receives 100% payment, the second receives 50%, and the third through fifth receive 50% (some exceptions apply). This is the Multiple Procedure Payment Reduction (MPPR).
Modifier 26 (Professional Component)
For services with both professional and technical components (like radiology), modifier 26 indicates you're billing only the professional component. Use only the professional component RVU values, not the global values.
Modifier 80 (Assistant Surgeon)
Assistant surgeons typically receive 16% of the primary surgeon's payment. Calculate the primary surgeon RVUs and payment, then multiply by 0.16 for the assistant surgeon amount.

Important Calculation Considerations
Facility vs. Non-Facility
Practice Expense RVUs differ based on whether services are performed in a facility (hospital) or non-facility (office) setting. Non-facility PE RVUs are typically higher because the physician's practice bears all overhead costs. Always use the correct PE RVU column for your setting.
Annual Updates
RVU values, GPCI multipliers, and the conversion factor change annually. Always use the current year's values for accurate calculations. CMS typically publishes updates in November for the following calendar year.
Commercial Payer Variations
While this guide focuses on Medicare calculations, commercial payers often use their own conversion factors and payment rules. Some may use Medicare RVUs but apply different multipliers or fee schedules. Always verify specific payer requirements.

Frequently Asked Questions
How do you calculate total RVUs?
Total RVU = (Work RVU × Work GPCI) + (Practice Expense RVU × PE GPCI) + (Malpractice RVU × MP GPCI). Each component is multiplied by its geographic adjustment factor before summing.
What is the Medicare conversion factor for 2025?
The 2025 Medicare Conversion Factor is $33.29 per RVU. This means each geographically adjusted RVU is worth $33.29 in Medicare reimbursement before applying any modifiers or adjustments.
Do I need to calculate RVUs for productivity tracking?
For productivity tracking, most physicians focus on work RVUs only, which don't require GPCI adjustments or conversion factors. Work RVUs directly measure your personal effort and are the standard metric in compensation models.
Where can I find current RVU values?
RVU values are published annually by CMS in the Medicare Physician Fee Schedule, available on CMS.gov. For quick lookups, use our free Work RVU Calculator or the RVU Tracker app with the complete 2025 database.
How do GPCI values affect my payment?
GPCI adjusts payment for regional cost differences. Areas with high costs of living (like San Francisco or New York) have GPCI values above 1.0, increasing payment. Lower-cost areas have GPCI below 1.0, decreasing payment. This ensures fair reimbursement based on local practice costs.
