About 0KWX0YZ

0KWX0YZ is the ICD-10-PCS code for a revision procedure on the upper muscle using an open approach with other device. 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 myotomy, the ICD-9-CM procedure title it maps to (83.02).

For a different body part, codes include 0KWY0YZ (lower muscle).

The same procedure with a different approach is coded 0KWX3YZ (percutaneous) and 0KWX4YZ (percutaneous endoscopic).

With a different device, use 0KWX00Z (drainage device), 0KWX07Z (autologous tissue substitute), 0KWX0JZ (synthetic substitute), 0KWX0KZ (nonautologous tissue substitute) and 0KWX0MZ (stimulator lead).

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” and “Other O.R. Procedures for Injuries”.

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