About 0Y0B4ZZ

0Y0B4ZZ is the ICD-10-PCS code for a alteration procedure on the left lower extremity using a percutaneous endoscopic approach. In ICD-10-PCS, alteration means modifying the anatomic structure of a body part without affecting the function of the body part.

In plain terms, this corresponds to size reduction plastic operation, the ICD-9-CM procedure title it maps to (86.83).

For a different body part, codes include 0Y004ZZ (right buttock), 0Y014ZZ (left buttock), 0Y094ZZ (right lower extremity), 0Y0C4ZZ (right upper leg), 0Y0D4ZZ (left upper leg), 0Y0F4ZZ (right knee region) and 5 more.

The same procedure with a different approach is coded 0Y0B0ZZ (open) and 0Y0B3ZZ (percutaneous).

With a different device, use 0Y0B47Z (autologous tissue substitute), 0Y0B4JZ (synthetic substitute) and 0Y0B4KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures for Injuries”.

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