About 09U50KZ

09U50KZ is the ICD-10-PCS code for a supplement procedure on the right middle ear 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 other repair of middle ear, the ICD-9-CM procedure title it maps to (19.9).

For a different body part, codes include 09U00KZ (right external ear), 09U10KZ (left external ear), 09U20KZ (bilateral external ear), 09U60KZ (left middle ear), 09U70KZ (right tympanic membrane), 09U80KZ (left tympanic membrane) and 19 more.

The same procedure with a different approach is coded 09U58KZ (via natural or artificial opening endoscopic).

With a different device, use 09U507Z (autologous tissue substitute) and 09U50JZ (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.
