About 0WBH4ZX

0WBH4ZX is the ICD-10-PCS code for a excision procedure on the retroperitoneum 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 intra-abdominal mass, the ICD-9-CM procedure title it maps to (54.24).

For a different body part, codes include 0WB04ZX (head), 0WB24ZX (face), 0WB34ZX (oral cavity and throat), 0WB44ZX (upper jaw), 0WB54ZX (lower jaw), 0WB64ZX (neck) and 7 more.

The same procedure with a different approach is coded 0WBH0ZX (open) and 0WBH3ZX (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.
