About ICD-9-CM 996.03
996.03 is an ICD-9-CM diagnosis code for mechanical complication due to coronary bypass 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 T82.211A (Breakdown (mechanical) of coronary artery bypass graft, initial encounter), T82.212A (Displacement of coronary artery bypass graft, initial encounter) and T82.213A (Leakage of coronary artery bypass graft, initial encounter). All of these are approximate matches, so review the record to pick the right one.
