1 Training for Trauma Registrars 7/18/14 Holly Hedegaard, MD, MSPH INJURY CODES IN ICD-10-CM 1

2 General description of ICD-10-CM Chapter 19, Injury Diagnosis Codes Break for Lunch Chapter 20, External Cause of Injury Codes Related codes to consider TRAINING OVERVIEW 2

3 Clinical modification of ICD-10 First draft for public comment in 1997 Field tested by the AHA and AHIMA in 2003 New concepts/codes added annually through the ICD Coordination and Maintenance Committee at NCHS ICD-10-CM 3

4 Relevant codes for ambulatory and managed care encounters Greater specificity in code assignment Addition of sixth and seventh characters Combination diagnosis/symptom codes Expanded injury codes Of the approx 70,000 codes in ICD-10-CM, 43,000 are in the injury chapters! WHAT’S NEW IN ICD-10-CM? 4

5 1. Scroll down to “FY 2015 release of ICD-10-CM” 2. Select “ICD-10-CM PDF Format” 3. Select “ICD10CM_FY2015_Full_PDF.zip” 4. Select “FY15_Tabular.PDF” 5. Select Chapter 19 (injury diagnosis codes) or Chapter 20 (external cause codes) ICD-10-CM ON-LINE 5
