CMS 2026 data source

Uses the CMS April 2026 Physician Fee Schedule RVU files, GPCI localities, and 2026 conversion factors. Estimates should be verified against official CMS files for billing decisions.

For calculator workflows, calculator inputs are processed in the browser. Contact, lead forms and PDF download forms are separate submissions.

Calculation governance

Source-of-truth field map

These controls keep calculator output readable as a Medicare payment estimate with visible CPT, setting, locality, conversion factor, and workflow boundaries.

FieldSourceBoundary
CPT or HCPCS codeCMS PFS Relative Value Files RVU record and descriptor fieldsThe site can look up economics after a code is selected; it does not choose the clinically correct code.
Work RVUCMS PFS Relative Value Files work RVU componentUse for physician productivity context; do not treat work RVU alone as Medicare payment.
Practice expense RVUCMS PFS Relative Value Files facility and non-facility PE RVU fieldsThe selected site of service controls which PE RVU enters the formula.
Malpractice RVUCMS PFS Relative Value Files malpractice RVU componentMP RVU is adjusted only by MP GPCI, not by a blended geography factor.
GPCI localityCMS GPCI locality records for Work, PE, and MP indexesLocality is the payment assumption; state pages are navigation surfaces, not statewide payment guarantees.
Conversion factor2026 conversion factor assumptions used by the imported non-QPP and QPP/APM filesQPP/APM status changes the final multiplier only when participation status applies.
Formula stepPractitioner check
Confirm CPT/HCPCS recordVerify the CPT code and descriptor before using RVU values for payment, benchmark, or contract interpretation.
Select site of serviceChoose facility or non-facility so the correct practice expense RVU enters the calculation.
Apply component GPCICalculate adjusted total RVU as work RVU x Work GPCI plus selected PE RVU x PE GPCI plus MP RVU x MP GPCI.
Select conversion factor statusApply non-QPP or QPP/APM conversion factor only after adjusted total RVU is complete.
Read result boundaryTreat the result as a Medicare payment estimate, not a coding, legal, payer-contract, or employment-contract conclusion.

Practitioner review checks

What must travel with a result

CheckRequirement
Code assumptionRecord CPT code and descriptor beside every exported estimate.
Setting assumptionKeep facility or non-facility visible whenever total RVU or payment is shown.
Locality assumptionShow Work, PE, and MP GPCI separately so users can explain why payment moved.
Participation assumptionUse QPP/APM only when the clinician or organization status is known for the reviewed period.
Compensation boundarySeparate Medicare payment estimates from salary, benchmark, contract, collections, and payer-rate analysis; the result is not a coding, legal, payer-contract, or employment-contract conclusion.
Export boundaryPDF or CSV exports should carry assumptions with the result and remain tool outputs, not login-gated products.
