About 0SB50ZX

0SB50ZX is the ICD-10-PCS code for a excision procedure on the sacrococcygeal joint using an open approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 0SB00ZX (lumbar vertebral joint), 0SB20ZX (lumbar vertebral disc), 0SB30ZX (lumbosacral joint), 0SB40ZX (lumbosacral disc), 0SB60ZX (coccygeal joint), 0SB70ZX (right sacroiliac joint) and 15 more.

The same procedure with a different approach is coded 0SB53ZX (percutaneous) and 0SB54ZX (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.
