About 0RST04Z
0RST04Z is the ICD-10-PCS code for a reposition procedure on the left carpometacarpal joint using an open 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 open reduction of dislocation of hand and finger, the ICD-9-CM procedure title it maps to (79.84).
For a different body part, codes include 0RS004Z (occipital-cervical joint), 0RS104Z (cervical vertebral joint), 0RS404Z (cervicothoracic vertebral joint), 0RS604Z (thoracic vertebral joint), 0RSA04Z (thoracolumbar vertebral joint), 0RSC04Z (right temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RST34Z (percutaneous), 0RST44Z (percutaneous endoscopic) and 0RSTX4Z (external).
With a different device, use 0RST05Z (external fixation device) and 0RST0ZZ (no device).
It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC), DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), DRG 906 (Hand Procedures for Injuries), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Hand Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
