About 09CE0ZZ

09CE0ZZ is the ICD-10-PCS code for a extirpation procedure on the left inner ear using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other incision, excision, and destruction of inner ear, the ICD-9-CM procedure title it maps to (20.79).

For a different body part, codes include 09C00ZZ (right external ear), 09C10ZZ (left external ear), 09C30ZZ (right external auditory canal), 09C40ZZ (left external auditory canal), 09C50ZZ (right middle ear), 09C60ZZ (left middle ear) and 22 more.

The same procedure with a different approach is coded 09CE8ZZ (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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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