About 09WH7KZ

09WH7KZ is the ICD-10-PCS code for a revision procedure on the right ear using a via natural or artificial opening approach with nonautologous 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 09W77KZ (right tympanic membrane), 09W87KZ (left tympanic membrane), 09W97KZ (right auditory ossicle), 09WA7KZ (left auditory ossicle), 09WJ7KZ (left ear) and 09WK7KZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09WH0KZ (open), 09WH3KZ (percutaneous), 09WH4KZ (percutaneous endoscopic), 09WH8KZ (via natural or artificial opening endoscopic) and 09WHXKZ (external).

With a different device, use 09WH70Z (drainage device), 09WH77Z (autologous tissue substitute), 09WH7DZ (intraluminal device), 09WH7JZ (synthetic substitute) and 09WH7YZ (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.
