About 09NF7ZZ

09NF7ZZ is the ICD-10-PCS code for a release procedure on the right eustachian tube using a via natural or artificial opening 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 09N37ZZ (right external auditory canal), 09N47ZZ (left external auditory canal), 09N77ZZ (right tympanic membrane), 09N87ZZ (left tympanic membrane), 09NG7ZZ (left eustachian tube), 09NL7ZZ (nasal turbinate) and 1 more.

The same procedure with a different approach is coded 09NF0ZZ (open), 09NF3ZZ (percutaneous), 09NF4ZZ (percutaneous endoscopic) and 09NF8ZZ (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.
