About 09TG7ZZ
09TG7ZZ is the ICD-10-PCS code for a resection procedure on the left eustachian tube using a via natural or artificial opening 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 09T77ZZ (right tympanic membrane), 09T87ZZ (left tympanic membrane), 09TF7ZZ (right eustachian tube), 09TL7ZZ (nasal turbinate) and 09TN7ZZ (nasopharynx).
The same procedure with a different approach is coded 09TG0ZZ (open), 09TG4ZZ (percutaneous endoscopic) and 09TG8ZZ (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.
