About 09TM8ZZ
09TM8ZZ is the ICD-10-PCS code for a resection procedure on the nasal septum using a via natural or artificial opening 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 submucous resection of nasal septum, the ICD-9-CM procedure title it maps to (21.5).
For a different body part, codes include 09T58ZZ (right middle ear), 09T68ZZ (left middle ear), 09T78ZZ (right tympanic membrane), 09T88ZZ (left tympanic membrane), 09T98ZZ (right auditory ossicle), 09TA8ZZ (left auditory ossicle) and 18 more.
The same procedure with a different approach is coded 09TM0ZZ (open) and 09TM4ZZ (percutaneous 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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It was added in FY2018, effective October 1, 2017.
