About 09Q4XZZ

09Q4XZZ is the ICD-10-PCS code for a repair procedure on the left external auditory canal using an external approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to suture of laceration of external ear, the ICD-9-CM procedure title it maps to (18.4).

For a different body part, codes include 09Q0XZZ (right external ear), 09Q1XZZ (left external ear), 09Q2XZZ (bilateral external ear), 09Q3XZZ (right external auditory canal), 09QFXZZ (right eustachian tube), 09QGXZZ (left eustachian tube) and 1 more.

The same procedure with a different approach is coded 09Q40ZZ (open), 09Q43ZZ (percutaneous), 09Q44ZZ (percutaneous endoscopic), 09Q47ZZ (via natural or artificial opening) and 09Q48ZZ (via natural or artificial opening endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
