About 02B64ZX

02B64ZX is the ICD-10-PCS code for a excision procedure on the right atrium using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of heart, the ICD-9-CM procedure title it maps to (37.25).

For a different body part, codes include 02B44ZX (coronary vein), 02B54ZX (atrial septum), 02B74ZX (left atrium), 02B84ZX (conduction mechanism), 02B94ZX (chordae tendineae), 02BD4ZX (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02B60ZX (open) and 02B63ZX (percutaneous).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
