About 0YBL4ZZ

0YBL4ZZ is the ICD-10-PCS code for a excision procedure on the left ankle region using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to radical excision of skin lesion, the ICD-9-CM procedure title it maps to (86.4).

For a different body part, codes include 0YB04ZZ (right buttock), 0YB14ZZ (left buttock), 0YB54ZZ (right inguinal region), 0YB64ZZ (left inguinal region), 0YB74ZZ (right femoral region), 0YB84ZZ (left femoral region) and 11 more.

The same procedure with a different approach is coded 0YBL0ZZ (open) and 0YBL3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 500 (Soft Tissue Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R. Procedures”, “Soft Tissue Procedures” and 3 more.

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