About 09T98ZZ

09T98ZZ is the ICD-10-PCS code for a resection procedure on the right auditory ossicle 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 stapedectomy, the ICD-9-CM procedure title it maps to (19.19).

For a different body part, codes include 09T58ZZ (right middle ear), 09T68ZZ (left middle ear), 09T78ZZ (right tympanic membrane), 09T88ZZ (left tympanic membrane), 09TA8ZZ (left auditory ossicle), 09TB8ZZ (right mastoid sinus) and 18 more.

The same procedure with a different approach is coded 09T90ZZ (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.
