About 09588ZZ
09588ZZ is the ICD-10-PCS code for a destruction procedure on the left tympanic membrane using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
In plain terms, this corresponds to other excision of middle ear, the ICD-9-CM procedure title it maps to (20.59).
For a different body part, codes include 09538ZZ (right external auditory canal), 09548ZZ (left external auditory canal), 09558ZZ (right middle ear), 09568ZZ (left middle ear), 09578ZZ (right tympanic membrane), 09598ZZ (right auditory ossicle) and 20 more.
The same procedure with a different approach is coded 09580ZZ (open), 09583ZZ (percutaneous), 09584ZZ (percutaneous endoscopic) and 09587ZZ (via natural or artificial opening).
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.
