About 09CN7ZZ

09CN7ZZ is the ICD-10-PCS code for a extirpation procedure on the nasopharynx using a via natural or artificial opening 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 09C37ZZ (right external auditory canal), 09C47ZZ (left external auditory canal), 09C77ZZ (right tympanic membrane), 09C87ZZ (left tympanic membrane), 09CF7ZZ (right eustachian tube), 09CG7ZZ (left eustachian tube) and 1 more.

The same procedure with a different approach is coded 09CN0ZZ (open), 09CN3ZZ (percutaneous), 09CN4ZZ (percutaneous endoscopic) 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.
