About 0WQ34ZZ

0WQ34ZZ is the ICD-10-PCS code for a repair procedure on the oral cavity and throat using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to suture of laceration of other part of mouth, closure of fistula of mouth and other plastic repair of mouth, the ICD-9-CM procedure titles it maps to (27.52, 27.53 and 27.59).

For a different body part, codes include 0WQ04ZZ (head), 0WQ24ZZ (face), 0WQ44ZZ (upper jaw), 0WQ54ZZ (lower jaw), 0WQ64ZZ (neck), 0WQ84ZZ (chest wall) and 6 more.

The same procedure with a different approach is coded 0WQ30ZZ (open), 0WQ33ZZ (percutaneous) and 0WQ3XZZ (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 Skin, Subcutaneous Tissue and Breast Procedures” and 2 more.

It was added in FY2018, effective October 1, 2017.
