About 0RWM45Z

0RWM45Z is the ICD-10-PCS code for a revision procedure on the left elbow joint 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 arthrotomy, elbow, the ICD-9-CM procedure title it maps to (80.12).

The same procedure with a different approach is coded 0RWM05Z (open), 0RWM35Z (percutaneous) and 0RWMX5Z (external).
