Non-ST Elevation Myocardial Infarction Secondary to Stent Thrombus
A patient, who is status post coronary angioplasty with stent placement in the LAD two days prior, is readmitted for a non-ST elevation myocardial infarction (NSTEMI) due to thrombus in the stent. Based on the instructional notes under I21.A9 , it appears that codes I21.A9 , Other myocardial infarction type, T82.897A , Other specified complication of cardiac prosthetic devices, implants and grafts, initial encounter, and I97.89 , Other post procedural complications and disorders of circulatory system, not elsewhere classified, should all be assigned. Code I97.190 , Other postprocedural cardiac functional disturbances following cardiac surgery, also seems appropriate. What are the correct diagnosis codes and sequencing of an acute myocardial infarction (MI) due to stent thrombus following coronary angioplasty and stent placement? ...
