About 09TF4ZZ

09TF4ZZ is the ICD-10-PCS code for a resection procedure on the right eustachian tube 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 operations on eustachian tube, the ICD-9-CM procedure title it maps to (20.8).

For a different body part, codes include 09T04ZZ (right external ear), 09T14ZZ (left external ear), 09T74ZZ (right tympanic membrane), 09T84ZZ (left tympanic membrane), 09TB4ZZ (right mastoid sinus), 09TC4ZZ (left mastoid sinus) and 14 more.

The same procedure with a different approach is coded 09TF0ZZ (open), 09TF7ZZ (via natural or artificial opening) and 09TF8ZZ (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.
