About 09CS8ZZ
09CS8ZZ is the ICD-10-PCS code for a extirpation procedure on the right frontal sinus using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to frontal sinusotomy, the ICD-9-CM procedure title it maps to (22.41).
For a different body part, codes include 09C38ZZ (right external auditory canal), 09C48ZZ (left external auditory canal), 09C58ZZ (right middle ear), 09C68ZZ (left middle ear), 09C78ZZ (right tympanic membrane), 09C88ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09CS0ZZ (open), 09CS3ZZ (percutaneous) and 09CS4ZZ (percutaneous 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 was added in FY2018, effective October 1, 2017.
