About 0TB44ZX

0TB44ZX is the ICD-10-PCS code for a excision procedure on the left kidney pelvis 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 closed [percutaneous] [needle] biopsy of kidney and biopsy of perirenal or perivesical tissue, the ICD-9-CM procedure titles it maps to (55.23 and 59.21).

For a different body part, codes include 0TB04ZX (right kidney), 0TB14ZX (left kidney), 0TB34ZX (right kidney pelvis), 0TB64ZX (right ureter), 0TB74ZX (left ureter), 0TBB4ZX (bladder) and 2 more.

The same procedure with a different approach is coded 0TB40ZX (open), 0TB43ZX (percutaneous), 0TB47ZX (via natural or artificial opening) and 0TB48ZX (via natural or artificial opening endoscopic).

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.
