About 0KX84Z1

0KX84Z1 is the ICD-10-PCS code for a transfer procedure on the left upper arm muscle using a percutaneous endoscopic approach (qualifier: subcutaneous tissue). 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 0KX04Z1 (head muscle), 0KX14Z1 (facial muscle), 0KX24Z1 (right neck muscle), 0KX34Z1 (left neck muscle), 0KX44Z1 (tongue, palate, pharynx muscle), 0KX54Z1 (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KX80Z1 (open).

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 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures” and “Soft Tissue Procedures”.

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