About 09WHXKZ

09WHXKZ is the ICD-10-PCS code for a revision procedure on the right ear using an external approach with nonautologous tissue substitute. 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 09WJXKZ (left ear) and 09WKXKZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09WH0KZ (open), 09WH3KZ (percutaneous), 09WH4KZ (percutaneous endoscopic), 09WH7KZ (via natural or artificial opening) and 09WH8KZ (via natural or artificial opening endoscopic).

With a different device, use 09WHX0Z (drainage device), 09WHX7Z (autologous tissue substitute), 09WHXDZ (intraluminal device) and 09WHXJZ (synthetic substitute).

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.
