About 09NF8ZZ
09NF8ZZ is the ICD-10-PCS code for a release procedure on the right eustachian tube using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
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 09N38ZZ (right external auditory canal), 09N48ZZ (left external auditory canal), 09N58ZZ (right middle ear), 09N68ZZ (left middle ear), 09N78ZZ (right tympanic membrane), 09N88ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09NF0ZZ (open), 09NF3ZZ (percutaneous), 09NF4ZZ (percutaneous endoscopic) and 09NF7ZZ (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.
