About 09WY40Z

09WY40Z is the ICD-10-PCS code for a revision procedure on the sinus using a percutaneous endoscopic 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 sinusotomy, not otherwise specified, the ICD-9-CM procedure title it maps to (22.50).

For a different body part, codes include 09WH40Z (right ear), 09WJ40Z (left ear) and 09WK40Z (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09WY00Z (open), 09WY30Z (percutaneous) and 09WYX0Z (external).

With a different device, use 09WY4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC) and DRG 136 (Sinus and Mastoid Procedures without CC/MCC), under the surgical category “Sinus and Mastoid Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
