About 0SSD0ZZ
0SSD0ZZ is the ICD-10-PCS code for a reposition procedure on the left knee joint using an open 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 open reduction of dislocation of knee, the ICD-9-CM procedure title it maps to (79.86).

The same procedure with a different approach is coded 0SSD3ZZ (percutaneous), 0SSD4ZZ (percutaneous endoscopic) and 0SSDXZZ (external).
