About 0KXJ0ZZ

0KXJ0ZZ is the ICD-10-PCS code for a transfer procedure on the left thorax muscle using an open approach. In ICD-10-PCS, transfer means moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part.

In plain terms, this corresponds to muscle flap graft to breast, the ICD-9-CM procedure title it maps to (85.85).

For a different body part, codes include 0KX00ZZ (head muscle), 0KX10ZZ (facial muscle), 0KX20ZZ (right neck muscle), 0KX30ZZ (left neck muscle), 0KX40ZZ (tongue, palate, pharynx muscle), 0KX50ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KXJ4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 573 (Skin Graft for Skin Ulcer or Cellulitis with MCC), DRG 574 (Skin Graft for Skin Ulcer or Cellulitis with CC), DRG 575 (Skin Graft for Skin Ulcer or Cellulitis without CC/MCC), DRG 576 (Skin Graft Except for Skin Ulcer or Cellulitis with MCC), DRG 577 (Skin Graft Except for Skin Ulcer or Cellulitis with CC) and DRG 578 (Skin Graft Except for Skin Ulcer or Cellulitis without CC/MCC), under the surgical categories “Skin Graft”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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