About 09T74ZZ
09T74ZZ is the ICD-10-PCS code for a resection procedure on the right tympanic membrane using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
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 09T04ZZ (right external ear), 09T14ZZ (left external ear), 09T84ZZ (left tympanic membrane), 09TB4ZZ (right mastoid sinus), 09TC4ZZ (left mastoid sinus), 09TF4ZZ (right eustachian tube) and 14 more.
The same procedure with a different approach is coded 09T70ZZ (open), 09T77ZZ (via natural or artificial opening) and 09T78ZZ (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.
