About 095T4ZZ
095T4ZZ is the ICD-10-PCS code for a destruction procedure on the left frontal sinus using a percutaneous 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 frontal sinusectomy, the ICD-9-CM procedure title it maps to (22.42).
For a different body part, codes include 09504ZZ (right external ear), 09514ZZ (left external ear), 09534ZZ (right external auditory canal), 09544ZZ (left external auditory canal), 09574ZZ (right tympanic membrane), 09584ZZ (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 095T0ZZ (open), 095T3ZZ (percutaneous) and 095T8ZZ (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.
