About 09BF4ZZ
09BF4ZZ is the ICD-10-PCS code for a excision procedure on the right eustachian tube using a percutaneous endoscopic 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 operations on eustachian tube, the ICD-9-CM procedure title it maps to (20.8).
For a different body part, codes include 09B04ZZ (right external ear), 09B14ZZ (left external ear), 09B34ZZ (right external auditory canal), 09B44ZZ (left external auditory canal), 09B74ZZ (right tympanic membrane), 09B84ZZ (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 09BF0ZZ (open), 09BF3ZZ (percutaneous), 09BF7ZZ (via natural or artificial opening) and 09BF8ZZ (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.
