About 0KTM4ZZ

0KTM4ZZ is the ICD-10-PCS code for a resection procedure on the perineum muscle using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other myectomy, the ICD-9-CM procedure title it maps to (83.45).

For a different body part, codes include 0KT04ZZ (head muscle), 0KT14ZZ (facial muscle), 0KT24ZZ (right neck muscle), 0KT34ZZ (left neck muscle), 0KT44ZZ (tongue, palate, pharynx muscle), 0KT54ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KTM0ZZ (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”, “Soft Tissue Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 1 more.
