About 090K37Z
090K37Z is the ICD-10-PCS code for a alteration procedure on the nasal mucosa and soft tissue using a percutaneous 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 augmentation rhinoplasty, the ICD-9-CM procedure title it maps to (21.85).
For a different body part, codes include 090037Z (right external ear), 090137Z (left external ear) and 090237Z (bilateral external ear).
The same procedure with a different approach is coded 090K07Z (open), 090K47Z (percutaneous endoscopic) and 090KX7Z (external).
With a different device, use 090K3JZ (synthetic substitute), 090K3KZ (nonautologous tissue substitute) and 090K3ZZ (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.
