About 09023KZ
09023KZ is the ICD-10-PCS code for a alteration procedure on the bilateral external ear using a percutaneous 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 09003KZ (right external ear), 09013KZ (left external ear) and 090K3KZ (nasal mucosa and soft tissue).
The same procedure with a different approach is coded 09020KZ (open), 09024KZ (percutaneous endoscopic) and 0902XKZ (external).
With a different device, use 090237Z (autologous tissue substitute), 09023JZ (synthetic substitute) and 09023ZZ (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.
