Sequence 7820 PCI for multivessel disease is indicating if the PCI procedure was performed in the presence of multivessel disease. The notes further clarify what constitutes multivessel disease and to code yes if this is the initial or first PCI procedure for the cath lab indication and the patient has obstructive disease of 70% stenosis or worse in two or more coronary vessels and or disease of 50 to 70% stenosis in two or more coronary vessels with a non-invasive FFR or IFR evidence of ischemia in that territory and or there is left main stenosis of 50% or worse. A coronary divessel is defined as the LAD and any of its branches, the left circumflex and any of its branches, the RCA and any of its branches and a true ramus branch of two millimeters or larger. As well, the site would code yes if this is a subsequent planned staged PCI procedure of a vessel not treated during their initial PCI procedure and that first PCI could have been during a prior admission or during this admission but it must have occurred within 90 days of the initial PCI procedure.
