About 0SS004Z

0SS004Z is the ICD-10-PCS code for a reposition procedure on the lumbar vertebral 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 other specified sites, the ICD-9-CM procedure title it maps to (79.89).

For a different body part, codes include 0SS304Z (lumbosacral joint), 0SS504Z (sacrococcygeal joint), 0SS604Z (coccygeal joint), 0SS704Z (right sacroiliac joint), 0SS804Z (left sacroiliac joint), 0SS904Z (right hip joint) and 13 more.

The same procedure with a different approach is coded 0SS034Z (percutaneous), 0SS044Z (percutaneous endoscopic) and 0SS0X4Z (external).

With a different device, use 0SS00ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures 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 “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
