About 09QM4ZZ

09QM4ZZ is the ICD-10-PCS code for a repair procedure on the nasal septum using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other septoplasty, the ICD-9-CM procedure title it maps to (21.88).

For a different body part, codes include 09Q04ZZ (right external ear), 09Q14ZZ (left external ear), 09Q24ZZ (bilateral external ear), 09Q34ZZ (right external auditory canal), 09Q44ZZ (left external auditory canal), 09Q74ZZ (right tympanic membrane) and 17 more.

The same procedure with a different approach is coded 09QM0ZZ (open), 09QM3ZZ (percutaneous) and 09QM8ZZ (via natural or artificial opening endoscopic).

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.
