About 0QWN4KZ

0QWN4KZ is the ICD-10-PCS code for a revision procedure on the right metatarsal using a percutaneous endoscopic 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 incision of bone without division, tarsals and metatarsals, the ICD-9-CM procedure title it maps to (77.18).

For a different body part, codes include 0QW04KZ (lumbar vertebra), 0QW14KZ (sacrum), 0QW24KZ (right pelvic bone), 0QW34KZ (left pelvic bone), 0QW44KZ (right acetabulum), 0QW54KZ (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QWN0KZ (open), 0QWN3KZ (percutaneous) and 0QWNXKZ (external).

With a different device, use 0QWN44Z (internal fixation device), 0QWN45Z (external fixation device), 0QWN47Z (autologous tissue substitute) and 0QWN4JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 503 (Foot Procedures with MCC), DRG 504 (Foot Procedures with CC) and DRG 505 (Foot Procedures without CC/MCC), under the surgical category “Foot Procedures”.

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