About 09TR8ZZ
09TR8ZZ is the ICD-10-PCS code for a resection procedure on the left maxillary sinus 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 excision of lesion of maxillary sinus with other approach, the ICD-9-CM procedure title it maps to (22.62).
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 09TR0ZZ (open) and 09TR4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC), DRG 136 (Sinus and Mastoid 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 “Sinus and Mastoid Procedures” and “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.
It was added in FY2018, effective October 1, 2017.
