About 09BG7ZX

09BG7ZX is the ICD-10-PCS code for a excision procedure on the left eustachian tube using a via natural or artificial opening approach (qualifier: diagnostic). 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 09B37ZX (right external auditory canal), 09B47ZX (left external auditory canal), 09B77ZX (right tympanic membrane), 09B87ZX (left tympanic membrane), 09BF7ZX (right eustachian tube), 09BL7ZX (nasal turbinate) and 1 more.

The same procedure with a different approach is coded 09BG0ZX (open), 09BG3ZX (percutaneous), 09BG4ZX (percutaneous endoscopic) and 09BG8ZX (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.
