About ICD-9-CM 988.0
988.0 is an ICD-9-CM diagnosis code for toxic effect of fish and shellfish eaten as food. 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 24 ICD-10-CM codes, such as T61.01XA (Ciguatera fish poisoning, accidental (unintentional), initial encounter), T61.02XA (Ciguatera fish poisoning, intentional self-harm, initial encounter) and T61.03XA (Ciguatera fish poisoning, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
