About 09WJ8YZ

09WJ8YZ is the ICD-10-PCS code for a revision procedure on the left ear using a via natural or artificial opening endoscopic approach with other device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 09WH8YZ (right ear), 09WK8YZ (nasal mucosa and soft tissue) and 09WY8YZ (sinus).

The same procedure with a different approach is coded 09WJ0YZ (open), 09WJ3YZ (percutaneous), 09WJ4YZ (percutaneous endoscopic) and 09WJ7YZ (via natural or artificial opening).

With a different device, use 09WJ80Z (drainage device), 09WJ87Z (autologous tissue substitute), 09WJ8DZ (intraluminal device), 09WJ8JZ (synthetic substitute) and 09WJ8KZ (nonautologous tissue substitute).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
