About 09BN3ZX
09BN3ZX is the ICD-10-PCS code for a excision procedure on the nasopharynx using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to pharyngeal biopsy, the ICD-9-CM procedure title it maps to (29.12).
For a different body part, codes include 09B03ZX (right external ear), 09B13ZX (left external ear), 09B33ZX (right external auditory canal), 09B43ZX (left external auditory canal), 09B73ZX (right tympanic membrane), 09B83ZX (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 09BN0ZX (open), 09BN4ZX (percutaneous endoscopic), 09BN7ZX (via natural or artificial opening) and 09BN8ZX (via natural or artificial opening endoscopic).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
