About 0RST4ZZ
0RST4ZZ is the ICD-10-PCS code for a reposition procedure on the left carpometacarpal 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 hand and finger, the ICD-9-CM procedure title it maps to (79.74).
For a different body part, codes include 0RS04ZZ (occipital-cervical joint), 0RS14ZZ (cervical vertebral joint), 0RS44ZZ (cervicothoracic vertebral joint), 0RS64ZZ (thoracic vertebral joint), 0RSA4ZZ (thoracolumbar vertebral joint), 0RSC4ZZ (right temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RST0ZZ (open), 0RST3ZZ (percutaneous) and 0RSTXZZ (external).
With a different device, use 0RST44Z (internal fixation device) and 0RST45Z (external 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.
