About 0PSL4BZ

0PSL4BZ is the ICD-10-PCS code for a reposition procedure on the left ulna using a percutaneous endoscopic approach with external fixation device, monoplanar. 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, closed reduction of fracture without internal fixation, radius and ulna and application of external fixator device, monoplanar system, the ICD-9-CM procedure titles it maps to (78.13, 79.02 and 84.71).

For a different body part, codes include 0PSC4BZ (right humeral head), 0PSD4BZ (left humeral head), 0PSF4BZ (right humeral shaft), 0PSG4BZ (left humeral shaft), 0PSH4BZ (right radius), 0PSJ4BZ (left radius) and 1 more.

The same procedure with a different approach is coded 0PSL0BZ (open) and 0PSL3BZ (percutaneous).

With a different device, use 0PSL44Z (internal fixation device), 0PSL45Z (external fixation device), 0PSL46Z (internal fixation device, intramedullary), 0PSL4CZ (external fixation device, ring), 0PSL4DZ (external fixation device, hybrid) and 0PSL4ZZ (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.
