About 0SSB04Z

0SSB04Z is the ICD-10-PCS code for a reposition procedure on the left hip 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 hip, the ICD-9-CM procedure title it maps to (79.85).

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 0SSB34Z (percutaneous), 0SSB44Z (percutaneous endoscopic) and 0SSBX4Z (external).

With a different device, use 0SSB05Z (external fixation device) and 0SSB0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 480 (Hip and Femur Procedures Except Major Joint with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 481 (Hip and Femur Procedures Except Major Joint with CC), DRG 482 (Hip and Femur Procedures Except Major Joint 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 “Hip and Femur Procedures Except Major Joint”, “Other O.R. Procedures for Injuries” and “Limb Reattachment, Hip and Femur Procedures for Multiple Significant Trauma”.

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