About 09B14ZX
09B14ZX is the ICD-10-PCS code for a excision procedure on the left external ear using a percutaneous endoscopic 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 biopsy of external ear, the ICD-9-CM procedure title it maps to (18.12).
For a different body part, codes include 09B04ZX (right external ear), 09B34ZX (right external auditory canal), 09B44ZX (left external auditory canal), 09B74ZX (right tympanic membrane), 09B84ZX (left tympanic membrane), 09BB4ZX (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09B10ZX (open), 09B13ZX (percutaneous) and 09B1XZX (external).
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.
