About 09UD8KZ

09UD8KZ is the ICD-10-PCS code for a supplement procedure on the right inner ear 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.

In plain terms, this corresponds to other operations on middle and inner ear, the ICD-9-CM procedure title it maps to (20.99).

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 09UD0KZ (open).

With a different device, use 09UD87Z (autologous tissue substitute) and 09UD8JZ (synthetic substitute).

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.
