About 09WKX0Z

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

The same procedure with a different approach is coded 09WK00Z (open), 09WK30Z (percutaneous), 09WK40Z (percutaneous endoscopic), 09WK70Z (via natural or artificial opening) and 09WK80Z (via natural or artificial opening endoscopic).

With a different device, use 09WKX7Z (autologous tissue substitute), 09WKXDZ (intraluminal device), 09WKXJZ (synthetic substitute) and 09WKXKZ (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.
