About ICD-9-CM 996.00
996.00 is an ICD-9-CM diagnosis code for mechanical complication of unspecified 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 4 ICD-10-CM codes, such as T82.519A (Breakdown (mechanical) of unspecified cardiac and vascular devices and implants, initial encounter), T82.529A (Displacement of unspecified cardiac and vascular devices and implants, initial encounter) and T82.539A (Leakage of unspecified cardiac and vascular devices and implants, initial encounter). All of these are approximate matches, so review the record to pick the right one.
