About 0RST0ZZ
0RST0ZZ is the ICD-10-PCS code for a reposition procedure on the left carpometacarpal joint using an open 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 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 0RS00ZZ (occipital-cervical joint), 0RS10ZZ (cervical vertebral joint), 0RS40ZZ (cervicothoracic vertebral joint), 0RS60ZZ (thoracic vertebral joint), 0RSA0ZZ (thoracolumbar vertebral joint), 0RSC0ZZ (right temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RST3ZZ (percutaneous), 0RST4ZZ (percutaneous endoscopic) and 0RSTXZZ (external).
With a different device, use 0RST04Z (internal fixation device) and 0RST05Z (external fixation 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.
