About 08W177Z

08W177Z is the ICD-10-PCS code for a revision procedure on the left eye 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 other operations on eyeball, the ICD-9-CM procedure title it maps to (16.99).

For a different body part, codes include 08W077Z (right eye).

The same procedure with a different approach is coded 08W107Z (open), 08W137Z (percutaneous), 08W187Z (via natural or artificial opening endoscopic) and 08W1X7Z (external).

With a different device, use 08W170Z (drainage device), 08W173Z (infusion device), 08W17CZ (extraluminal device), 08W17DZ (intraluminal device), 08W17JZ (synthetic substitute), 08W17KZ (nonautologous tissue substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 115 (Extraocular Procedures Except Orbit), under the surgical category “Extraocular Procedures Except Orbit”.

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