About 0KSW0ZZ

0KSW0ZZ is the ICD-10-PCS code for a reposition procedure on the left foot muscle using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to other muscle transposition, the ICD-9-CM procedure title it maps to (83.79).

For a different body part, codes include 0KS00ZZ (head muscle), 0KS10ZZ (facial muscle), 0KS20ZZ (right neck muscle), 0KS30ZZ (left neck muscle), 0KS40ZZ (tongue, palate, pharynx muscle), 0KS50ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KSW4ZZ (percutaneous endoscopic).

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 Endocrine, Nutritional and Metabolic O.R.
