About 09W877Z

09W877Z is the ICD-10-PCS code for a revision procedure on the left tympanic membrane using a via natural or artificial opening 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 revision of tympanoplasty, the ICD-9-CM procedure title it maps to (19.6).

For a different body part, codes include 09W777Z (right tympanic membrane), 09W977Z (right auditory ossicle), 09WA77Z (left auditory ossicle), 09WH77Z (right ear), 09WJ77Z (left ear) and 09WK77Z (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09W807Z (open) and 09W887Z (via natural or artificial opening endoscopic).

With a different device, use 09W87JZ (synthetic substitute) and 09W87KZ (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.
