About 09WH47Z

09WH47Z is the ICD-10-PCS code for a revision procedure on the right ear using a percutaneous endoscopic approach with autologous tissue substitute. 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 operations on middle and inner ear, the ICD-9-CM procedure title it maps to (20.99).

For a different body part, codes include 09WJ47Z (left ear) and 09WK47Z (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09WH07Z (open), 09WH37Z (percutaneous), 09WH77Z (via natural or artificial opening), 09WH87Z (via natural or artificial opening endoscopic) and 09WHX7Z (external).

With a different device, use 09WH40Z (drainage device), 09WH4DZ (intraluminal device), 09WH4JZ (synthetic substitute), 09WH4KZ (nonautologous tissue substitute) and 09WH4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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