ICD-10-CM Coding: Report External Cause Codes Accurately and Confidently With These Tips

Article Overview

This article covers ICD-10-CM external cause codes and why they may be reported even though they are not nationally required. It is aimed at coders, billers, compliance staff, and other healthcare reimbursement professionals who need a broader understanding of when these supplementary diagnosis codes may be relevant, how they support claim detail, and what general categories of encounter information they can capture. The discussion also notes that payer and state requirements may differ and that external cause reporting is treated as secondary information rather than a principal diagnosis.
