About 0RBA4ZX

0RBA4ZX is the ICD-10-PCS code for a excision procedure on the thoracolumbar vertebral joint using a percutaneous endoscopic 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 0RB04ZX (occipital-cervical joint), 0RB14ZX (cervical vertebral joint), 0RB34ZX (cervical vertebral disc), 0RB44ZX (cervicothoracic vertebral joint), 0RB54ZX (cervicothoracic vertebral disc), 0RB64ZX (thoracic vertebral joint) and 22 more.

The same procedure with a different approach is coded 0RBA0ZX (open) and 0RBA3ZX (percutaneous).

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.
