About 09CN4ZZ

09CN4ZZ is the ICD-10-PCS code for a extirpation procedure on the nasopharynx using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to Pharyngotomy, the ICD-9-CM procedure title it maps to (29.0).

For a different body part, codes include 09C04ZZ (right external ear), 09C14ZZ (left external ear), 09C34ZZ (right external auditory canal), 09C44ZZ (left external auditory canal), 09C74ZZ (right tympanic membrane), 09C84ZZ (left tympanic membrane) and 16 more.

The same procedure with a different approach is coded 09CN0ZZ (open), 09CN3ZZ (percutaneous), 09CN7ZZ (via natural or artificial opening) and 09CN8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
