ICD-9-CM diagnosis code (retired)
996.09 — Other mechanical complication of cardiac device, implant, and graft
About ICD-9-CM 996.09
996.09 is an ICD-9-CM diagnosis code for other mechanical complication of cardiac device, implant, and graft. 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 8 ICD-10-CM codes, such as T82.221A (Breakdown (mechanical) of biological heart valve graft, initial encounter), T82.222A (Displacement of biological heart valve graft, initial encounter) and T82.223A (Leakage of biological heart valve graft, initial encounter). All of these are approximate matches, so review the record to pick the right one.
