About 09983ZX
09983ZX is the ICD-10-PCS code for a drainage procedure on the left tympanic membrane using a percutaneous 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 middle and inner ear, the ICD-9-CM procedure title it maps to (20.32).
For a different body part, codes include 09903ZX (right external ear), 09913ZX (left external ear), 09933ZX (right external auditory canal), 09943ZX (left external auditory canal), 09973ZX (right tympanic membrane), 099B3ZX (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09980ZX (open), 09984ZX (percutaneous endoscopic), 09987ZX (via natural or artificial opening) and 09988ZX (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.
