- External Cause (E Code)
E961 is a legacy ICD-9-CM external cause code (E code) that described assault by corrosive or caustic substance, except poisoning. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. CMS assigns no direct ICD-10-CM equivalent for this code (a No Map flag in the General Equivalence Mappings), so the closest current code must be chosen from the clinical documentation.
