About 09024ZZ

09024ZZ is the ICD-10-PCS code for a alteration procedure on the bilateral external ear using a percutaneous endoscopic approach. 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 09004ZZ (right external ear), 09014ZZ (left external ear) and 090K4ZZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09020ZZ (open), 09023ZZ (percutaneous) and 0902XZZ (external).

With a different device, use 090247Z (autologous tissue substitute), 09024JZ (synthetic substitute) and 09024KZ (nonautologous tissue 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), 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.
