About ICD-9-CM 994.0
994.0 is an ICD-9-CM diagnosis code for effects of lightning. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as T75.00XA (Unspecified effects of lightning, initial encounter) and T75.01XA (Shock due to being struck by lightning, initial encounter). All of these are approximate matches, so review the record to pick the right one.
