What 93462 covers
This service covers puncturing the interatrial septum and advancing a catheter into the left heart for diagnostic catheterization. A cardiologist typically performs it in a cardiac catheterization laboratory when left-sided pressure or other hemodynamic assessment is needed through transseptal access. The technique may be selected for patients whose anatomy or clinical circumstances make this route appropriate for the planned left heart study.
Report 93462 only with a qualifying primary left heart catheterization code, such as 93452, 93453, or 93458–93461. The record should support the transseptal approach and the left heart catheterization performed, including relevant catheter findings or hemodynamic measurements. CMS classifies 93462 as an add-on code; it is billed with the primary procedure and paid within that procedure’s global period.
