About 095R8ZZ
095R8ZZ is the ICD-10-PCS code for a destruction procedure on the left maxillary sinus using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
In plain terms, this corresponds to radical maxillary antrotomy, the ICD-9-CM procedure title it maps to (22.31).
For a different body part, codes include 09538ZZ (right external auditory canal), 09548ZZ (left external auditory canal), 09558ZZ (right middle ear), 09568ZZ (left middle ear), 09578ZZ (right tympanic membrane), 09588ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 095R0ZZ (open), 095R3ZZ (percutaneous) and 095R4ZZ (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.
