About ICD-9-CM 973.8
973.8 is an ICD-9-CM diagnosis code for poisoning by other specified agents primarily affecting the gastrointestinal system. 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 4 ICD-10-CM codes, such as T47.8X1A (Poisoning by other agents primarily affecting gastrointestinal system, accidental (unintentional), initial encounter), T47.8X2A (Poisoning by other agents primarily affecting gastrointestinal system, intentional self-harm, initial encounter) and T47.8X3A (Poisoning by other agents primarily affecting gastrointestinal system, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
