About 09983ZZ
09983ZZ is the ICD-10-PCS code for a drainage procedure on the left tympanic membrane using a percutaneous approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other myringotomy, the ICD-9-CM procedure title it maps to (20.09).
For a different body part, codes include 09903ZZ (right external ear), 09913ZZ (left external ear), 09933ZZ (right external auditory canal), 09943ZZ (left external auditory canal), 09973ZZ (right tympanic membrane), 099B3ZZ (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09980ZZ (open), 09984ZZ (percutaneous endoscopic), 09987ZZ (via natural or artificial opening) and 09988ZZ (via natural or artificial opening endoscopic).
With a different device, use 099830Z (drainage device).
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.
