About 0SS04ZZ

0SS04ZZ is the ICD-10-PCS code for a reposition procedure on the lumbar vertebral 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 other specified sites, the ICD-9-CM procedure title it maps to (79.79).

For a different body part, codes include 0SS34ZZ (lumbosacral joint), 0SS54ZZ (sacrococcygeal joint), 0SS64ZZ (coccygeal joint), 0SS74ZZ (right sacroiliac joint), 0SS84ZZ (left sacroiliac joint), 0SS94ZZ (right hip joint) and 13 more.

The same procedure with a different approach is coded 0SS00ZZ (open), 0SS03ZZ (percutaneous) and 0SS0XZZ (external).

With a different device, use 0SS044Z (internal 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.
