About 0SSD04Z

0SSD04Z is the ICD-10-PCS code for a reposition procedure on the left knee joint using an open 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 open reduction of dislocation of knee, the ICD-9-CM procedure title it maps to (79.86).

For a different body part, codes include 0SS004Z (lumbar vertebral joint), 0SS304Z (lumbosacral joint), 0SS504Z (sacrococcygeal joint), 0SS604Z (coccygeal joint), 0SS704Z (right sacroiliac joint), 0SS804Z (left sacroiliac joint) and 13 more.

The same procedure with a different approach is coded 0SSD34Z (percutaneous), 0SSD44Z (percutaneous endoscopic) and 0SSDX4Z (external).

With a different device, use 0SSD05Z (external fixation device) and 0SSD0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Knee Procedures with Principal Diagnosis of Infection”, “Knee Procedures without Principal Diagnosis of Infection”, “Other O.R.
