About 09UP4KZ
09UP4KZ is the ICD-10-PCS code for a supplement procedure on the accessory sinus using a percutaneous 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 09UB4KZ (right mastoid sinus), 09UC4KZ (left mastoid sinus), 09UL4KZ (nasal turbinate), 09UM4KZ (nasal septum), 09UQ4KZ (right maxillary sinus), 09UR4KZ (left maxillary sinus) and 6 more.
The same procedure with a different approach is coded 09UP0KZ (open), 09UP3KZ (percutaneous), 09UP7KZ (via natural or artificial opening) and 09UP8KZ (via natural or artificial opening endoscopic).
With a different device, use 09UP47Z (autologous tissue substitute) and 09UP4JZ (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”.
It was added in FY2020, effective October 1, 2019.
