About 09WK4YZ

09WK4YZ is the ICD-10-PCS code for a revision procedure on the nasal mucosa and soft tissue using a percutaneous 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 09WH4YZ (right ear), 09WJ4YZ (left ear) and 09WY4YZ (sinus).

The same procedure with a different approach is coded 09WK0YZ (open), 09WK3YZ (percutaneous), 09WK7YZ (via natural or artificial opening) and 09WK8YZ (via natural or artificial opening endoscopic).

With a different device, use 09WK40Z (drainage device), 09WK47Z (autologous tissue substitute), 09WK4DZ (intraluminal device), 09WK4JZ (synthetic substitute) and 09WK4KZ (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.
