About 0X050ZZ

0X050ZZ is the ICD-10-PCS code for a alteration procedure on the left axilla using an open 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 0X020ZZ (right shoulder region), 0X030ZZ (left shoulder region), 0X040ZZ (right axilla), 0X060ZZ (right upper extremity), 0X070ZZ (left upper extremity), 0X080ZZ (right upper arm) and 7 more.

The same procedure with a different approach is coded 0X053ZZ (percutaneous) and 0X054ZZ (percutaneous endoscopic).

With a different device, use 0X0507Z (autologous tissue substitute), 0X050JZ (synthetic substitute) and 0X050KZ (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.
