ICD-9-CM diagnosis code (retired)
996.04 — Mechanical complication of automatic implantable cardiac defibrillator
About ICD-9-CM 996.04
996.04 is an ICD-9-CM diagnosis code for mechanical complication of automatic implantable cardiac defibrillator. 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 6 ICD-10-CM codes, such as T82.110A (Breakdown (mechanical) of cardiac electrode, initial encounter), T82.111A (Breakdown (mechanical) of cardiac pulse generator (battery), initial encounter) and T82.120A (Displacement of cardiac electrode, initial encounter). All of these are approximate matches, so review the record to pick the right one.
