About 0SSDX4Z

0SSDX4Z is the ICD-10-PCS code for a reposition procedure on the left knee joint using an external approach with internal fixation device. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to closed reduction of dislocation of knee, the ICD-9-CM procedure title it maps to (79.76).

For a different body part, codes include 0SS0X4Z (lumbar vertebral joint), 0SS3X4Z (lumbosacral joint), 0SS5X4Z (sacrococcygeal joint), 0SS6X4Z (coccygeal joint), 0SS7X4Z (right sacroiliac joint), 0SS8X4Z (left sacroiliac joint) and 13 more.

The same procedure with a different approach is coded 0SSD04Z (open), 0SSD34Z (percutaneous) and 0SSD44Z (percutaneous endoscopic).

With a different device, use 0SSDX5Z (external fixation device) and 0SSDXZZ (no 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.
