About 09BF8ZZ
09BF8ZZ is the ICD-10-PCS code for a excision procedure on the right eustachian tube using a via natural or artificial opening 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 09B38ZZ (right external auditory canal), 09B48ZZ (left external auditory canal), 09B58ZZ (right middle ear), 09B68ZZ (left middle ear), 09B78ZZ (right tympanic membrane), 09B88ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09BF0ZZ (open), 09BF3ZZ (percutaneous), 09BF4ZZ (percutaneous endoscopic) and 09BF7ZZ (via natural or artificial opening).
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.
