About 09B3XZX
09B3XZX is the ICD-10-PCS code for a excision procedure on the right external auditory canal using an external 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 09B0XZX (right external ear), 09B1XZX (left external ear), 09B4XZX (left external auditory canal) and 09BKXZX (nasal mucosa and soft tissue).
The same procedure with a different approach is coded 09B30ZX (open), 09B33ZX (percutaneous), 09B34ZX (percutaneous endoscopic), 09B37ZX (via natural or artificial opening) and 09B38ZX (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.
