Example #4: Mapping a One to Multiple Choices Conversion

• Find the ICD-9 code that you need to map to ICD-10 and enter the number into the ICD-9 code field.
  You may choose to use the drop-down list of Diagnosis Codes or simply enter an ICD-9 code into the field
• When you select a diagnosis code from the dropdown list, the Mapping occurs automatically and you do not need to click the Crosswalk button.
  
• Click the “Crosswalk” button (if needed) and the results will appear
  
• In the example above, ICD-9 code 896.2 returns multiple results for equivalent ICD-10 codes which are organized by Choice Lists.
• When Choice Lists appear, it signifies that multiple ICD-10 codes must be used to properly represent the ICD-9 code, and you must select one ICD-10 code from each choice list. In this example you must select one ICD-10 code from the choice 1 options, and one ICD-10 code from the Choice 2 options. Both codes would be needed to represent the equivalent for the ICD-9 code you mapped.
  
  Also remember to look at the final column to note whether results have the Approximate checkbox checked. The codes you select from the choice list might not be the actual codes you ultimately use. If the codes are approximate you may find more specific codes to use instead.
• For each individual Choice List, one of the listed ICD-10 codes must be used. For this example, two codes must be used: one code must be chosen from Choice List 1 and one code must be chosen from Choice List 2.
• From this information we can see that there are multiple results. Either of these ICD-10 codes are approximately equivalent to the ICD-9 code.
• Open up each available option by clicking the ICD-10 Code. You will be taken to that code’s Tabular Listing.
  
• The code is now seen in its position in the Tabular Listing allowing you to view it.
  If the ICD-10 code is only approximately equivalent, study the surrounding codes closely to see if a more appropriate and specific code exists.
  
• Once a code has been chosen from Choice List 1, return to the Mappings tab and proceed to Choice List 2 to look for the most appropriate code. Continue this until one code has been chosen from each numbered Choice List.
• The list of codes that have been found must be used together to most closely equate to the single ICD-9 code. For this example: Using the ICD-9 code of 896.2 is roughly equal to using both the S98.921A and S98.922A ICD-10 codes.
