About 09C58ZZ
09C58ZZ is the ICD-10-PCS code for a extirpation procedure on the right middle ear using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to incision of middle ear, the ICD-9-CM procedure title it maps to (20.23).
For a different body part, codes include 09C38ZZ (right external auditory canal), 09C48ZZ (left external auditory canal), 09C68ZZ (left middle ear), 09C78ZZ (right tympanic membrane), 09C88ZZ (left tympanic membrane), 09C98ZZ (right auditory ossicle) and 20 more.
The same procedure with a different approach is coded 09C50ZZ (open).
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 was added in FY2018, effective October 1, 2017.
