About ICD-9-CM 976.6
976.6 is an ICD-9-CM diagnosis code for poisoning by anti-infectives and other drugs and preparations for ear, nose, and throat. 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 T49.6X1A (Poisoning by otorhinolaryngological drugs and preparations, accidental (unintentional), initial encounter), T49.6X2A (Poisoning by otorhinolaryngological drugs and preparations, intentional self-harm, initial encounter) and T49.6X3A (Poisoning by otorhinolaryngological drugs and preparations, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
