About 09WHX0Z

09WHX0Z is the ICD-10-PCS code for a revision procedure on the right ear using an external approach with drainage 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 09WJX0Z (left ear), 09WKX0Z (nasal mucosa and soft tissue) and 09WYX0Z (sinus).

The same procedure with a different approach is coded 09WH00Z (open), 09WH30Z (percutaneous), 09WH40Z (percutaneous endoscopic), 09WH70Z (via natural or artificial opening) and 09WH80Z (via natural or artificial opening endoscopic).

With a different device, use 09WHX7Z (autologous tissue substitute), 09WHXDZ (intraluminal device), 09WHXJZ (synthetic substitute) and 09WHXKZ (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
