Prepare for new ICD-10-CM codes that take effect on Oct. 1 :

June 28, 2016

For the first time in many years, International Classification of Diseases codes will be updated. This will be the largest update to the code set due to the code freeze that was implemented during the lengthy transition to International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM).

The new codes will take effect on Oct. 1, so begin preparing now.

There will be 1,943 new codes, 422 revised codes and 305 “invalid” codes, which will have additional digits to further classify them.

This article and the August issue of Coding Corner will highlight nearly all changes and will include codes that are most relevant to pediatrics.

The dash (-) used within a code indicates more digits are required. Unspecified laterality codes were included within the ICD-10-CM code set, but those codes are not included in this article.
