About 09BQ4ZZ

09BQ4ZZ is the ICD-10-PCS code for a excision procedure on the right maxillary sinus using a percutaneous endoscopic 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 other approach, the ICD-9-CM procedure title it maps to (22.62).

For a different body part, codes include 09B04ZZ (right external ear), 09B14ZZ (left external ear), 09B34ZZ (right external auditory canal), 09B44ZZ (left external auditory canal), 09B74ZZ (right tympanic membrane), 09B84ZZ (left tympanic membrane) and 16 more.

The same procedure with a different approach is coded 09BQ0ZZ (open), 09BQ3ZZ (percutaneous) and 09BQ8ZZ (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.
