About 09BR0ZZ

09BR0ZZ is the ICD-10-PCS code for a excision procedure on the left maxillary sinus using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of lesion of maxillary sinus with Caldwell-Luc approach and excision of lesion of maxillary sinus with other approach, the ICD-9-CM procedure titles it maps to (22.61 and 22.62).

For a different body part, codes include 09B00ZZ (right external ear), 09B10ZZ (left external ear), 09B30ZZ (right external auditory canal), 09B40ZZ (left external auditory canal), 09B50ZZ (right middle ear), 09B60ZZ (left middle ear) and 22 more.

The same procedure with a different approach is coded 09BR3ZZ (percutaneous), 09BR4ZZ (percutaneous endoscopic) and 09BR8ZZ (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), DRG 136 (Sinus and Mastoid Procedures without CC/MCC), DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Sinus and Mastoid Procedures” and “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
