About 0SSD45Z
0SSD45Z is the ICD-10-PCS code for a reposition procedure on the left knee joint using a percutaneous endoscopic approach with external 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 0SS945Z (right hip joint), 0SSB45Z (left hip joint), 0SSC45Z (right knee joint), 0SSF45Z (right ankle joint), 0SSG45Z (left ankle joint), 0SSH45Z (right tarsal joint) and 7 more.
The same procedure with a different approach is coded 0SSD05Z (open), 0SSD35Z (percutaneous) and 0SSDX5Z (external).
With a different device, use 0SSD44Z (internal fixation device) and 0SSD4ZZ (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.
