About 099880Z
099880Z is the ICD-10-PCS code for a drainage procedure on the left tympanic membrane using a via natural or artificial opening endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to myringotomy with insertion of tube, the ICD-9-CM procedure title it maps to (20.01).
For a different body part, codes include 099380Z (right external auditory canal), 099480Z (left external auditory canal), 099580Z (right middle ear), 099680Z (left middle ear), 099780Z (right tympanic membrane), 099980Z (right auditory ossicle) and 20 more.
The same procedure with a different approach is coded 099800Z (open), 099830Z (percutaneous), 099840Z (percutaneous endoscopic) and 099870Z (via natural or artificial opening).
With a different device, use 09988ZZ (no device).
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.
