About 09UA0KZ

09UA0KZ is the ICD-10-PCS code for a supplement procedure on the left auditory ossicle 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.

In plain terms, this corresponds to stapedectomy with incus replacement, the ICD-9-CM procedure title it maps to (19.11).

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 09UA8KZ (via natural or artificial opening endoscopic).

With a different device, use 09UA07Z (autologous tissue substitute) and 09UA0JZ (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
