About 09R50KZ

09R50KZ is the ICD-10-PCS code for a replacement procedure on the right middle ear using an open approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or 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 09R00KZ (right external ear), 09R10KZ (left external ear), 09R20KZ (bilateral external ear), 09R60KZ (left middle ear), 09R70KZ (right tympanic membrane), 09R80KZ (left tympanic membrane) and 8 more.

With a different device, use 09R507Z (autologous tissue substitute) and 09R50JZ (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.
