About 09BA8ZZ

09BA8ZZ is the ICD-10-PCS code for a excision procedure on the left auditory ossicle using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion 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 09B38ZZ (right external auditory canal), 09B48ZZ (left external auditory canal), 09B58ZZ (right middle ear), 09B68ZZ (left middle ear), 09B78ZZ (right tympanic membrane), 09B88ZZ (left tympanic membrane) and 20 more.

The same procedure with a different approach is coded 09BA0ZZ (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.
