About 09WH7YZ
09WH7YZ is the ICD-10-PCS code for a revision procedure on the right ear using a via natural or artificial opening 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
For a different body part, codes include 09WJ7YZ (left ear), 09WK7YZ (nasal mucosa and soft tissue) and 09WY7YZ (sinus).
The same procedure with a different approach is coded 09WH0YZ (open), 09WH3YZ (percutaneous), 09WH4YZ (percutaneous endoscopic) and 09WH8YZ (via natural or artificial opening endoscopic).
With a different device, use 09WH70Z (drainage device), 09WH77Z (autologous tissue substitute), 09WH7DZ (intraluminal device), 09WH7JZ (synthetic substitute) and 09WH7KZ (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.
