About 09NQ3ZZ
09NQ3ZZ is the ICD-10-PCS code for a release procedure on the right maxillary sinus using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to other repair of nasal sinus, the ICD-9-CM procedure title it maps to (22.79).
For a different body part, codes include 09N03ZZ (right external ear), 09N13ZZ (left external ear), 09N33ZZ (right external auditory canal), 09N43ZZ (left external auditory canal), 09N73ZZ (right tympanic membrane), 09N83ZZ (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 09NQ0ZZ (open), 09NQ4ZZ (percutaneous endoscopic) and 09NQ8ZZ (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.
