About 0KBW0ZZ

0KBW0ZZ is the ICD-10-PCS code for a excision procedure on the left foot muscle using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of lesion of muscle and other myectomy, the ICD-9-CM procedure titles it maps to (83.32 and 83.45).

For a different body part, codes include 0KB00ZZ (head muscle), 0KB10ZZ (facial muscle), 0KB20ZZ (right neck muscle), 0KB30ZZ (left neck muscle), 0KB40ZZ (tongue, palate, pharynx muscle), 0KB50ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KBW3ZZ (percutaneous) and 0KBW4ZZ (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 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 500 (Soft Tissue Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R.
