About 09WY7YZ
09WY7YZ is the ICD-10-PCS code for a revision procedure on the sinus 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 09WH7YZ (right ear), 09WJ7YZ (left ear) and 09WK7YZ (nasal mucosa and soft tissue).
The same procedure with a different approach is coded 09WY0YZ (open), 09WY3YZ (percutaneous), 09WY4YZ (percutaneous endoscopic) and 09WY8YZ (via natural or artificial opening endoscopic).
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.
