About 09B80ZZ
09B80ZZ is the ICD-10-PCS code for a excision procedure on the left tympanic membrane using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to excision of lesion of middle ear, the ICD-9-CM procedure title it maps to (20.51).
For a different body part, codes include 09B00ZZ (right external ear), 09B10ZZ (left external ear), 09B30ZZ (right external auditory canal), 09B40ZZ (left external auditory canal), 09B50ZZ (right middle ear), 09B60ZZ (left middle ear) and 22 more.
The same procedure with a different approach is coded 09B83ZZ (percutaneous), 09B84ZZ (percutaneous endoscopic), 09B87ZZ (via natural or artificial opening) and 09B88ZZ (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.
