3 Easy Steps to Finding the Right E/M Level Using an E/M Calculator

Have you checked out our free, new E/M Calculator yet? Using it is straightforward, but having a guide can be handy when a tool is new. Here’s how it works.

1. Access the E/M Calculator

If you’re going to use a tool, the first step is to get to it! If you aren’t a subscriber to one of our online coding packages, you can open the calculator by following the directions on our E/M Calculator page.

For those of you who use our online coding packages, the calculator is included with your subscription. After you sign in, look at the left-side menu on your home page. You’ll see the link to the E/M Calculator on the menu.

2. Use the Tabs to Find the Code Level

The E/M Calculator includes these tabs:

  • Patient Data: In this section, enter the type of service (like office/outpatient) and the date. There’s no personal patient data here, so you can rest easy about compliance.
  • History: Make your way through the checklist for chief complaint, HPI, ROS, and PFSH. Click the CMS buttons to see Documentation Guidelines (DGs) for that area.
  • Examination: Choose the 1995 or 1997 exam criteria to work your way through the requirements. Watch for helpful pop-ups with abbreviations of commonly used terms!
  • MDM: Fill in the boxes and review more CMS DGs to help asses the Medical Decision Making component for the visit.
  • Time-Based Coding: For times when you’re going to code based on time, use this tab to be sure you meet the requirements. Enter the time to see the final code level.
  • Critical Care Services: When you’re coding critical care, review the rules on this tab and enter time to determine the appropriate code level.
  • Final Code Level: Check the E/M level based on the data you entered. Watch for alerts that help ensure optimal coding, such as a note that using different exam criteria (1995 vs. 1997) would raise your level.

Tip: Click the “Save” button after you complete data entry in each tab to allow the calculator to use the information in tabulating the final E/M level.

3. Start Your Next Calculation

On the Final Coder Level tab, there’s a button to “Start New Code Calculation.” Click to move on to the next case!
