About 0WB43ZZ

0WB43ZZ is the ICD-10-PCS code for a excision procedure on the upper jaw using a percutaneous 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 other excision of mouth and radical excision of skin lesion, the ICD-9-CM procedure titles it maps to (27.49 and 86.4).

For a different body part, codes include 0WB03ZZ (head), 0WB23ZZ (face), 0WB33ZZ (oral cavity and throat), 0WB53ZZ (lower jaw), 0WB63ZZ (neck), 0WB83ZZ (chest wall) and 7 more.

The same procedure with a different approach is coded 0WB40ZZ (open), 0WB44ZZ (percutaneous endoscopic) and 0WB4XZZ (external).

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 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Circulatory System O.R. Procedures” and 4 more.
