ICD-9-CM Coding Advice for Healthcare Encounters in Hurricane Aftermath
Introduction This document is intended to be used as a guide to help coding professionals when coding healthcare encounters of those individuals affected by a hurricane. This coding advice has been approved by the four Cooperating Parties––American Health Information Management Association, American Hospital Association, Centers for Medicare & Medicaid Services, and National Center for Health Statistics. Use of E Codes An External Cause code (E code) should be assigned to identify the cause of an injury(ies) incurred as a result of the hurricane. The use of E codes is supplemental to the application...
