About 0KRT4KZ

0KRT4KZ is the ICD-10-PCS code for a replacement procedure on the left lower leg muscle using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to graft of muscle or fascia, the ICD-9-CM procedure title it maps to (83.82).

For a different body part, codes include 0KR04KZ (head muscle), 0KR14KZ (facial muscle), 0KR24KZ (right neck muscle), 0KR34KZ (left neck muscle), 0KR44KZ (tongue, palate, pharynx muscle), 0KR54KZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KRT0KZ (open).

With a different device, use 0KRT47Z (autologous tissue substitute) and 0KRT4JZ (synthetic substitute).

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”, “Soft Tissue Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 3 more.

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