About 099F7ZZ
099F7ZZ is the ICD-10-PCS code for a drainage procedure on the right eustachian tube using a via natural or artificial opening approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases 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 09937ZZ (right external auditory canal), 09947ZZ (left external auditory canal), 09957ZZ (right middle ear), 09967ZZ (left middle ear), 09977ZZ (right tympanic membrane), 09987ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 099F0ZZ (open), 099F3ZZ (percutaneous), 099F4ZZ (percutaneous endoscopic) and 099F8ZZ (via natural or artificial opening endoscopic).
With a different device, use 099F70Z (drainage device).
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.
