About 0KXF4Z9

0KXF4Z9 is the ICD-10-PCS code for a transfer procedure on the right trunk muscle using a percutaneous endoscopic approach (qualifier: gluteal artery perforator flap). 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 transfer or transplantation, the ICD-9-CM procedure title it maps to (83.77).

For a different body part, codes include 0KXG4Z9 (left trunk muscle).

The same procedure with a different approach is coded 0KXF0Z9 (open).

It is an operating-room procedure in the MS-DRG logic for DRG 582 (Mastectomy for Malignancy with CC/MCC), DRG 583 (Mastectomy for Malignancy without CC/MCC), DRG 584 (Breast Biopsy, Local Excision and Other Breast Procedures with CC/MCC), DRG 585 (Breast Biopsy, Local Excision and Other Breast Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC) and DRG 908 (Other O.R. Procedures for Injuries with CC), under the surgical categories “Mastectomy for Malignancy”, “Breast Biopsy, Local Excision and Other Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It was added in FY2018, effective October 1, 2017.
