About 090K0KZ

090K0KZ is the ICD-10-PCS code for a alteration procedure on the nasal mucosa and soft tissue using an open 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 augmentation rhinoplasty, the ICD-9-CM procedure title it maps to (21.85).

For a different body part, codes include 09000KZ (right external ear), 09010KZ (left external ear) and 09020KZ (bilateral external ear).

The same procedure with a different approach is coded 090K3KZ (percutaneous), 090K4KZ (percutaneous endoscopic) and 090KXKZ (external).

With a different device, use 090K07Z (autologous tissue substitute), 090K0JZ (synthetic substitute) and 090K0ZZ (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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 2 more.

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