About 0YBL4ZX
0YBL4ZX is the ICD-10-PCS code for a excision procedure on the left ankle region 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 biopsy of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.11).
For a different body part, codes include 0YB04ZX (right buttock), 0YB14ZX (left buttock), 0YB54ZX (right inguinal region), 0YB64ZX (left inguinal region), 0YB74ZX (right femoral region), 0YB84ZX (left femoral region) and 11 more.
The same procedure with a different approach is coded 0YBL0ZX (open) and 0YBL3ZX (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.
