About 09T68ZZ
09T68ZZ is the ICD-10-PCS code for a resection procedure on the left middle ear using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
In plain terms, this corresponds to other excision of middle ear, the ICD-9-CM procedure title it maps to (20.59).
For a different body part, codes include 09T58ZZ (right middle ear), 09T78ZZ (right tympanic membrane), 09T88ZZ (left tympanic membrane), 09T98ZZ (right auditory ossicle), 09TA8ZZ (left auditory ossicle), 09TB8ZZ (right mastoid sinus) and 18 more.
The same procedure with a different approach is coded 09T60ZZ (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”.
