About 09SK4ZZ

09SK4ZZ is the ICD-10-PCS code for a reposition procedure on the nasal mucosa and soft tissue using a percutaneous endoscopic approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to other repair and plastic operations on nose, the ICD-9-CM procedure title it maps to (21.89).

For a different body part, codes include 09S04ZZ (right external ear), 09S14ZZ (left external ear), 09S24ZZ (bilateral external ear), 09S74ZZ (right tympanic membrane), 09S84ZZ (left tympanic membrane), 09S94ZZ (right auditory ossicle) and 5 more.

The same procedure with a different approach is coded 09SK0ZZ (open) and 09SKXZZ (external).

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.
