About 09CU3ZZ
09CU3ZZ is the ICD-10-PCS code for a extirpation procedure on the right ethmoid sinus using a percutaneous approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to Ethmoidotomy, the ICD-9-CM procedure title it maps to (22.51).
For a different body part, codes include 09C03ZZ (right external ear), 09C13ZZ (left external ear), 09C33ZZ (right external auditory canal), 09C43ZZ (left external auditory canal), 09C73ZZ (right tympanic membrane), 09C83ZZ (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 09CU0ZZ (open), 09CU4ZZ (percutaneous endoscopic) and 09CU8ZZ (via natural or artificial opening endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC) and DRG 136 (Sinus and Mastoid Procedures without CC/MCC), under the surgical category “Sinus and Mastoid Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
