About 09TS0ZZ
09TS0ZZ is the ICD-10-PCS code for a resection procedure on the right frontal sinus using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
In plain terms, this corresponds to frontal sinusectomy, the ICD-9-CM procedure title it maps to (22.42).
For a different body part, codes include 09T00ZZ (right external ear), 09T10ZZ (left external ear), 09T50ZZ (right middle ear), 09T60ZZ (left middle ear), 09T70ZZ (right tympanic membrane), 09T80ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09TS4ZZ (percutaneous endoscopic) and 09TS8ZZ (via natural or artificial opening endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC) and DRG 136 (Sinus and Mastoid Procedures without CC/MCC), under the surgical category “Sinus and Mastoid Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
