About 0QWM45Z

0QWM45Z is the ICD-10-PCS code for a revision procedure on the left tarsal using a percutaneous endoscopic approach with external fixation device. 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 0QW245Z (right pelvic bone), 0QW345Z (left pelvic bone), 0QW645Z (right upper femur), 0QW745Z (left upper femur), 0QW845Z (right femoral shaft), 0QW945Z (left femoral shaft) and 13 more.

The same procedure with a different approach is coded 0QWM05Z (open), 0QWM35Z (percutaneous) and 0QWMX5Z (external).

With a different device, use 0QWM44Z (internal fixation device), 0QWM47Z (autologous tissue substitute), 0QWM4JZ (synthetic substitute) and 0QWM4KZ (nonautologous tissue 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.
