About 0PSL05Z

0PSL05Z is the ICD-10-PCS code for a reposition procedure on the left ulna using an open approach with external 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 application of external fixator device, radius and ulna and open reduction of fracture without internal fixation, radius and ulna, the ICD-9-CM procedure titles it maps to (78.13 and 79.22).

For a different body part, codes include 0PSC05Z (right humeral head), 0PSD05Z (left humeral head), 0PSF05Z (right humeral shaft), 0PSG05Z (left humeral shaft), 0PSH05Z (right radius), 0PSJ05Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PSL35Z (percutaneous) and 0PSL45Z (percutaneous endoscopic).

With a different device, use 0PSL04Z (internal fixation device), 0PSL06Z (internal fixation device, intramedullary), 0PSL0BZ (external fixation device, monoplanar), 0PSL0CZ (external fixation device, ring), 0PSL0DZ (external fixation device, hybrid) and 0PSL0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 510 (Shoulder, Elbow or Forearm Procedures, Except Major Joint Procedures with MCC), DRG 511 (Shoulder, Elbow or Forearm Procedures, Except Major Joint Procedures with CC), DRG 512 (Shoulder, Elbow or Forearm Procedures, Except Major Joint Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Shoulder, Elbow or Forearm Procedures, Except Major Joint Procedures”, “Other O.R. 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.
