About 0CQM0ZZ

0CQM0ZZ is the ICD-10-PCS code for a repair procedure on the pharynx using an open 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 plastic operation on pharynx and other repair of pharynx, the ICD-9-CM procedure titles it maps to (29.4 and 29.59).

For a different body part, codes include 0CQ00ZZ (upper lip), 0CQ10ZZ (lower lip), 0CQ20ZZ (hard palate), 0CQ30ZZ (soft palate), 0CQ40ZZ (buccal mucosa), 0CQ50ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CQM3ZZ (percutaneous), 0CQM4ZZ (percutaneous endoscopic), 0CQM7ZZ (via natural or artificial opening) and 0CQM8ZZ (via natural or artificial opening 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 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.
