The following is a description of the tables used in CBR201708 Modifier 25: Dermatology. There are links that will open the excel files that contain state and national statistics used in the analysis of rendering Part B providers for CBR201708. All of the analyses in this Comparative Billing Report (CBR) include only the Current Procedural Terminology (CPT®) Codes 99211-99215. CBR201708 includes claims with dates of service April 1, 2016 to March 31, 2017. These analyses are based on the latest version of claims available from the Integrated Data Repository as of July 11, 2017. Examples of each table can be found in the CBR201708 sample.
CPT® Codes, Abbreviated Descriptions, and Typical Times
Table 1 of CBR201708 provides a listing of the CPT® codes analyzed in this report. This table also includes an abbreviated description of each code and the typical times required for each code, assigned by the CPT® manual.
Summary of Your Utilization for E/M Codes and Modifier 25
Table 2 provides the statistics summary for the individual provider for each CPT® code analyzed in the CBR. The total allowed charges, allowed services, distinct visit count, and distinct beneficiary count are included for each CPT® code and modifier type. Please note the totals may not be equal to the sum of the rows. The number of beneficiaries and visit counts are unduplicated counts for each row and the total. If a beneficiary has billings for more than one CPT® code and/or modifier type, he/she would be counted in the beneficiary count in each applicable row; however, this beneficiary would be counted only once in the total.
Percentage of Services Appended with Modifier 25
Table 3 provides an analysis of the percentage of established patient E/M services appended with modifier 25. This percentage is calculated as the number of services with modifier 25 divided by the total number of services, and then multiplied by 100. This calculation covers all of the CPT® codes included in this CBR. Each provider’s percentage is compared to his/her state and the nation using the chi-square test at the alpha value of 0.05.

Average Minutes per Visit with Modifier 25 and without Modifier 25
Table 4 provides an analysis of the average minutes per visit for claim lines with modifier 25 and without modifier 25. Each CPT® code is assigned a value that corresponds to the typical minutes described in the CPT® code description in Table 1. The typical minutes is multiplied by the total allowed services for this code to arrive at the total minutes per code. The total minutes are summed by modifier designation (with modifier 25 and without modifier 25) and divided by the total number of visits for the modifier. A visit is defined as a single date of service by beneficiary. Generally, the total number of visits is equal to the total number of services by modifier designation. However, if multiple E/M services are allowed for a particular beneficiary and date of service, then these services would be combined in the same visit. The average minutes allowed per visit are calculated separately for services with modifier 25 and without modifier 25. The average is calculated as total minutes by modifier designation divided by the total number of visits by modifier designation. Each provider’s average is compared to his/her state and the nation using t-test at the alpha value of 0.05.

The calculation includes all allowed charges and beneficiaries with dates of service April 1, 2016 through March 31, 2017. Each provider’s average is compared to his/her state and the nation using the t-test at the alpha value of 0.05.
