About 09QN4ZZ

09QN4ZZ is the ICD-10-PCS code for a repair procedure on the nasopharynx 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 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 09Q04ZZ (right external ear), 09Q14ZZ (left external ear), 09Q24ZZ (bilateral external ear), 09Q34ZZ (right external auditory canal), 09Q44ZZ (left external auditory canal), 09Q74ZZ (right tympanic membrane) and 17 more.

The same procedure with a different approach is coded 09QN0ZZ (open), 09QN3ZZ (percutaneous), 09QN7ZZ (via natural or artificial opening) and 09QN8ZZ (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. Procedures”, “Other O.R.
