About 09UB0KZ
09UB0KZ is the ICD-10-PCS code for a supplement procedure on the right mastoid sinus using an open 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 09U00KZ (right external ear), 09U10KZ (left external ear), 09U20KZ (bilateral external ear), 09U50KZ (right middle ear), 09U60KZ (left middle ear), 09U70KZ (right tympanic membrane) and 19 more.
The same procedure with a different approach is coded 09UB3KZ (percutaneous), 09UB4KZ (percutaneous endoscopic), 09UB7KZ (via natural or artificial opening) and 09UB8KZ (via natural or artificial opening endoscopic).
With a different device, use 09UB07Z (autologous tissue substitute) and 09UB0JZ (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”.
