About 09CG0ZZ
09CG0ZZ is the ICD-10-PCS code for a extirpation procedure on the left eustachian tube using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from 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 09C00ZZ (right external ear), 09C10ZZ (left external ear), 09C30ZZ (right external auditory canal), 09C40ZZ (left external auditory canal), 09C50ZZ (right middle ear), 09C60ZZ (left middle ear) and 22 more.
The same procedure with a different approach is coded 09CG3ZZ (percutaneous), 09CG4ZZ (percutaneous endoscopic), 09CG7ZZ (via natural or artificial opening) and 09CG8ZZ (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.
