About 09S78ZZ

09S78ZZ is the ICD-10-PCS code for a reposition procedure on the right tympanic membrane using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to Myringoplasty, the ICD-9-CM procedure title it maps to (19.4).

For a different body part, codes include 09S88ZZ (left tympanic membrane), 09SF8ZZ (right eustachian tube), 09SG8ZZ (left eustachian tube) and 09SL8ZZ (nasal turbinate).

The same procedure with a different approach is coded 09S70ZZ (open), 09S74ZZ (percutaneous endoscopic) and 09S77ZZ (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.
