About 0R9T4ZX
0R9T4ZX is the ICD-10-PCS code for a drainage procedure on the left carpometacarpal joint using a percutaneous endoscopic 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 0R904ZX (occipital-cervical joint), 0R914ZX (cervical vertebral joint), 0R934ZX (cervical vertebral disc), 0R944ZX (cervicothoracic vertebral joint), 0R954ZX (cervicothoracic vertebral disc), 0R964ZX (thoracic vertebral joint) and 22 more.
The same procedure with a different approach is coded 0R9T0ZX (open) and 0R9T3ZX (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.
