Mapping is the key to ICD-10

Now that CMS has officially issued another delay in the implementation date for ICD-10 to October 1, 2015, you may be tempted to relax and wait. Instead you should consider this new delay a gift…a gift of extra time to prepare for the transition.Mapping is the Key

The easiest way to learn how ICD-10 will impact your practice is to look at mapping first. Mapping is the process of converting ICD-9 codes to ICD-10 codes and vice versa. Mapping from ICD-10 back to ICD-9 codes is referred to as Backward Mapping. Mapping from ICD-9 codes to ICD-10 codes is referred to as Forward Mapping. Looking at mapping first will help you visualize the transition based on ICD-9 codes you already use.

The coding guidelines for ICD-10 are almost identical to the ICD-9 guidelines. The process of coding is the same, i.e. you look up a word or phrase in the index, go to the appropriate tabular section and pick the code. You already know how to do that. But what do the new codes look like? How do the ICD-10 and ICD-9 codes relate to each other? How many of the 65,000+ ICD-10 codes apply to your practice?

ICD-10 mapping will answer those questions and serve as an introduction to the ICD-10 coding system. You can use mapping resources to:

• Convert ICD-9-CM codes to ICD-10-CM

• Convert ICD-10-CM codes to ICD-9-CM

• Update diagnostic coding databases

• Revise your billing forms

• Create common code lists for training purposes

Mapping can be used by anyone who wants to convert coded data including: all payers; all providers; medical researchers; informatics professionals; coding professionals; software vendors; organizations needing to create mappings that suit their internal purposes; and others who use coded data.
