About 0KWY4MZ

0KWY4MZ is the ICD-10-PCS code for a revision procedure on the lower muscle using a percutaneous endoscopic approach with stimulator lead. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other incision of soft tissue, the ICD-9-CM procedure title it maps to (83.09).

For a different body part, codes include 0KWX4MZ (upper muscle).

The same procedure with a different approach is coded 0KWY0MZ (open), 0KWY3MZ (percutaneous) and 0KWYXMZ (external).

With a different device, use 0KWY40Z (drainage device), 0KWY47Z (autologous tissue substitute), 0KWY4JZ (synthetic substitute), 0KWY4KZ (nonautologous tissue substitute) and 0KWY4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC), DRG 502 (Soft Tissue Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Soft Tissue Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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