About 09WH3YZ

09WH3YZ is the ICD-10-PCS code for a revision procedure on the right ear using a percutaneous 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 operations on middle and inner ear, the ICD-9-CM procedure title it maps to (20.99).

For a different body part, codes include 09WJ3YZ (left ear), 09WK3YZ (nasal mucosa and soft tissue) and 09WY3YZ (sinus).

The same procedure with a different approach is coded 09WH0YZ (open), 09WH4YZ (percutaneous endoscopic), 09WH7YZ (via natural or artificial opening) and 09WH8YZ (via natural or artificial opening endoscopic).

With a different device, use 09WH30Z (drainage device), 09WH37Z (autologous tissue substitute), 09WH3DZ (intraluminal device), 09WH3JZ (synthetic substitute) and 09WH3KZ (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.
