About 09UB8KZ
09UB8KZ is the ICD-10-PCS code for a supplement procedure on the right mastoid sinus using a via natural or artificial opening endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.
For a different body part, codes include 09U58KZ (right middle ear), 09U68KZ (left middle ear), 09U78KZ (right tympanic membrane), 09U88KZ (left tympanic membrane), 09U98KZ (right auditory ossicle), 09UA8KZ (left auditory ossicle) and 16 more.
The same procedure with a different approach is coded 09UB0KZ (open), 09UB3KZ (percutaneous), 09UB4KZ (percutaneous endoscopic) and 09UB7KZ (via natural or artificial opening).
With a different device, use 09UB87Z (autologous tissue substitute) and 09UB8JZ (synthetic substitute).
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”.
