About 09WK77Z

09WK77Z is the ICD-10-PCS code for a revision procedure on the nasal mucosa and soft tissue 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 09W777Z (right tympanic membrane), 09W877Z (left tympanic membrane), 09W977Z (right auditory ossicle), 09WA77Z (left auditory ossicle), 09WH77Z (right ear) and 09WJ77Z (left ear).

The same procedure with a different approach is coded 09WK07Z (open), 09WK37Z (percutaneous), 09WK47Z (percutaneous endoscopic), 09WK87Z (via natural or artificial opening endoscopic) and 09WKX7Z (external).

With a different device, use 09WK70Z (drainage device), 09WK7DZ (intraluminal device), 09WK7JZ (synthetic substitute), 09WK7KZ (nonautologous tissue substitute) and 09WK7YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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