One of our cardiologists performed the following: a left heart cath w/ coronaries, then a selective left subclavian angiogram to see whether there was a stenosis in the subclavian, and then a selective left internal mammary artery (LIMA) looking at it for a possible grafting site. How would we code this?
If the LIMA was imaged to see if it was appropriate as a graft, you would assign 93459 to identify the heart cath with grafts.
|93459||Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed, catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) with bypass graft angiography|
If the subclavian angiogram was diagnostic and not road-mapping, you would code 75710.
|75710||Angiography, extremity, unilateral, radiological supervision and interpretation|
