About ICD-9-CM 977.0
977.0 is an ICD-9-CM diagnosis code for poisoning by dietetics. 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 T50.5X1A (Poisoning by appetite depressants, accidental (unintentional), initial encounter), T50.5X2A (Poisoning by appetite depressants, intentional self-harm, initial encounter) and T50.5X3A (Poisoning by appetite depressants, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
