About 0KB34ZZ

0KB34ZZ is the ICD-10-PCS code for a excision procedure on the left neck muscle using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

The same procedure with a different approach is coded 0KB30ZZ (open) and 0KB33ZZ (percutaneous).

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 2 more.
