Watch a short YouTube movie and see how easy it is to calculate the CPT, RVU and Physicians Fees with ICD10Doc.

1. Find a CPT or CDT (Dental) code that interests you, with the search or reverse search functions on the Home page. You may find a CPT code also while browsing LCD (Local Coverage Determination). The result will show in its own box as CPT / HCPCS - with the relevant facility and non-facility RVU as well as the Anesthesia units whuch are used for calculating fees.

Click on the link that you'd like to continue with.

2. The next screen asks for the region - in order to match the correct Medicare carrier for reimbursement. From the drop down menu pick the region, the locality and the correct Medicare carrier for your caculation purposes and then click on the big blue button to calculate the fees.

3a. The page after picking the region will show Facility and Non Facility, RVU, Fees, Limiting charges and other details such as Impactors & Modifiers that may influence the physician fee.

3b. If on the other hand, the CPT code is an Anesthesia code, you may be on a page which at the bottom has a big blue button - Calculate Anesthesia Fees. Enter the Time Units and Modifying units and click on this button, since the Anesthesia fees are calculated differently. Read more about the Anesthesia Fees


From Wikipedia: The Current Procedural Terminology (CPT) code set is a medical code set maintained by the American Medical Association through the CPT Editorial Panel. The CPT code set (copyright protected by the AMA) describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical services and procedures among physicians, coders, patients, accreditation organizations, and payers for administrative, financial, and analytical purposes.
CPT coding is similar to ICD-9 and ICD-10 coding, except that it identifies the services rendered rather than the diagnosis on the claim.
ICD code sets also contain procedure codes but these are only used in the inpatient setting.
