About 09TG8ZZ
09TG8ZZ is the ICD-10-PCS code for a resection procedure on the left eustachian tube using a via natural or artificial opening 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 09T58ZZ (right middle ear), 09T68ZZ (left middle ear), 09T78ZZ (right tympanic membrane), 09T88ZZ (left tympanic membrane), 09T98ZZ (right auditory ossicle), 09TA8ZZ (left auditory ossicle) and 18 more.
The same procedure with a different approach is coded 09TG0ZZ (open), 09TG4ZZ (percutaneous endoscopic) and 09TG7ZZ (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.
