About 09PE0SZ

09PE0SZ is the ICD-10-PCS code for a removal procedure on the left inner ear using an open approach with hearing device. In ICD-10-PCS, removal means taking out or off a device from 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 09PD0SZ (right inner ear).

The same procedure with a different approach is coded 09PE7SZ (via natural or artificial opening) and 09PE8SZ (via natural or artificial opening endoscopic).

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.
