About 09570ZZ
09570ZZ is the ICD-10-PCS code for a destruction procedure on the right tympanic membrane using an open 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 09500ZZ (right external ear), 09510ZZ (left external ear), 09530ZZ (right external auditory canal), 09540ZZ (left external auditory canal), 09550ZZ (right middle ear), 09560ZZ (left middle ear) and 22 more.
The same procedure with a different approach is coded 09573ZZ (percutaneous), 09574ZZ (percutaneous endoscopic), 09577ZZ (via natural or artificial opening) and 09578ZZ (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.
