About 0SSD4ZZ
0SSD4ZZ is the ICD-10-PCS code for a reposition procedure on the left knee joint using a percutaneous endoscopic approach. 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 0SS04ZZ (lumbar vertebral joint), 0SS34ZZ (lumbosacral joint), 0SS54ZZ (sacrococcygeal joint), 0SS64ZZ (coccygeal joint), 0SS74ZZ (right sacroiliac joint), 0SS84ZZ (left sacroiliac joint) and 13 more.
The same procedure with a different approach is coded 0SSD0ZZ (open), 0SSD3ZZ (percutaneous) and 0SSDXZZ (external).
With a different device, use 0SSD44Z (internal fixation device) and 0SSD45Z (external fixation 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.
