About 0993XZX
0993XZX is the ICD-10-PCS code for a drainage procedure on the right external auditory canal using an external approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from 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 0990XZX (right external ear), 0991XZX (left external ear), 0994XZX (left external auditory canal) and 099KXZX (nasal mucosa and soft tissue).
The same procedure with a different approach is coded 09930ZX (open), 09933ZX (percutaneous), 09934ZX (percutaneous endoscopic), 09937ZX (via natural or artificial opening) and 09938ZX (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.
