About 0S970ZX

0S970ZX is the ICD-10-PCS code for a drainage procedure on the right sacroiliac joint using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of joint structure, other specified sites, the ICD-9-CM procedure title it maps to (80.39).

For a different body part, codes include 0S900ZX (lumbar vertebral joint), 0S920ZX (lumbar vertebral disc), 0S930ZX (lumbosacral joint), 0S940ZX (lumbosacral disc), 0S950ZX (sacrococcygeal joint), 0S960ZX (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0S973ZX (percutaneous) and 0S974ZX (percutaneous endoscopic).

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.
