About 0RS644Z
0RS644Z is the ICD-10-PCS code for a reposition procedure on the thoracic vertebral joint using a percutaneous endoscopic approach with internal fixation device. 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 other specified sites, the ICD-9-CM procedure title it maps to (79.79).
For a different body part, codes include 0RS044Z (occipital-cervical joint), 0RS144Z (cervical vertebral joint), 0RS444Z (cervicothoracic vertebral joint), 0RSA44Z (thoracolumbar vertebral joint), 0RSC44Z (right temporomandibular joint), 0RSD44Z (left temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RS604Z (open), 0RS634Z (percutaneous) and 0RS6X4Z (external).
With a different device, use 0RS64ZZ (no 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.
