About 09WA8JZ

09WA8JZ is the ICD-10-PCS code for a revision procedure on the left auditory ossicle using a via natural or artificial opening endoscopic approach with synthetic 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 revision of stapedectomy, the ICD-9-CM procedure title it maps to (19.29).

For a different body part, codes include 09W78JZ (right tympanic membrane), 09W88JZ (left tympanic membrane), 09W98JZ (right auditory ossicle), 09WH8JZ (right ear), 09WJ8JZ (left ear) and 09WK8JZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09WA0JZ (open) and 09WA7JZ (via natural or artificial opening).

With a different device, use 09WA87Z (autologous tissue substitute) and 09WA8KZ (nonautologous tissue substitute).

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.
