About 097F7ZZ

097F7ZZ is the ICD-10-PCS code for a dilation procedure on the right eustachian tube using a via natural or artificial opening approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular 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 097G7ZZ (left eustachian tube) and 097N7ZZ (nasopharynx).

The same procedure with a different approach is coded 097F0ZZ (open), 097F3ZZ (percutaneous), 097F4ZZ (percutaneous endoscopic) and 097F8ZZ (via natural or artificial opening endoscopic).

With a different device, use 097F7DZ (intraluminal 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.
