About 09TK4ZZ

09TK4ZZ is the ICD-10-PCS code for a resection procedure on the nasal mucosa and soft tissue using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to resection of nose, the ICD-9-CM procedure title it maps to (21.4).

For a different body part, codes include 09T04ZZ (right external ear), 09T14ZZ (left external ear), 09T74ZZ (right tympanic membrane), 09T84ZZ (left tympanic membrane), 09TB4ZZ (right mastoid sinus), 09TC4ZZ (left mastoid sinus) and 14 more.

The same procedure with a different approach is coded 09TK0ZZ (open), 09TK8ZZ (via natural or artificial opening endoscopic) and 09TKXZZ (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 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.
