About 090247Z

090247Z is the ICD-10-PCS code for a alteration procedure on the bilateral external ear using a percutaneous endoscopic approach with autologous 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 090047Z (right external ear), 090147Z (left external ear) and 090K47Z (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 090207Z (open), 090237Z (percutaneous) and 0902X7Z (external).

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