About 09QB8ZZ
09QB8ZZ is the ICD-10-PCS code for a repair procedure on the right mastoid sinus using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.
In plain terms, this corresponds to revision of mastoidectomy, the ICD-9-CM procedure title it maps to (20.92).
For a different body part, codes include 09Q38ZZ (right external auditory canal), 09Q48ZZ (left external auditory canal), 09Q58ZZ (right middle ear), 09Q68ZZ (left middle ear), 09Q78ZZ (right tympanic membrane), 09Q88ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09QB0ZZ (open), 09QB3ZZ (percutaneous) and 09QB4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC) and DRG 136 (Sinus and Mastoid Procedures without CC/MCC), under the surgical category “Sinus and Mastoid Procedures”.
It was added in FY2018, effective October 1, 2017.
