About 0901XKZ

0901XKZ is the ICD-10-PCS code for a alteration procedure on the left external ear using an external approach with nonautologous tissue substitute. In ICD-10-PCS, alteration means modifying the anatomic structure of a body part without affecting the function of the body part.

In plain terms, this corresponds to other plastic repair of external ear, the ICD-9-CM procedure title it maps to (18.79).

For a different body part, codes include 0900XKZ (right external ear), 0902XKZ (bilateral external ear) and 090KXKZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09010KZ (open), 09013KZ (percutaneous) and 09014KZ (percutaneous endoscopic).

With a different device, use 0901X7Z (autologous tissue substitute), 0901XJZ (synthetic substitute) and 0901XZZ (no device).

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), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
