About 09B84ZX
09B84ZX is the ICD-10-PCS code for a excision procedure on the left tympanic membrane 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 middle and inner ear, the ICD-9-CM procedure title it maps to (20.32).
For a different body part, codes include 09B04ZX (right external ear), 09B14ZX (left external ear), 09B34ZX (right external auditory canal), 09B44ZX (left external auditory canal), 09B74ZX (right tympanic membrane), 09BB4ZX (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09B80ZX (open), 09B83ZX (percutaneous), 09B87ZX (via natural or artificial opening) and 09B88ZX (via natural or artificial opening endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
