Article Overview

This article reviews how benign skin lesion reporting changes from ICD-9 to ICD-10 and why the transition matters for coders working with dermatology-related diagnoses. It compares the current ICD-9 family with the two ICD-10 families that replace it, highlights the broad categories included in each, and discusses the structure of the newer coding system with additional site and laterality specificity. The article is aimed at medical coders and billing professionals preparing for ICD-10 diagnosis coding changes.

Why This Topic Matters
