About 0PHL04Z

0PHL04Z is the ICD-10-PCS code for a insertion procedure on the left ulna using an open approach with internal fixation device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to internal fixation of bone without fracture reduction, radius and ulna, the ICD-9-CM procedure title it maps to (78.53).

For a different body part, codes include 0PH004Z (sternum), 0PH104Z (ribs, 1 to 2), 0PH204Z (ribs, 3 or more), 0PH304Z (cervical vertebra), 0PH404Z (thoracic vertebra), 0PH504Z (right scapula) and 20 more.

The same procedure with a different approach is coded 0PHL34Z (percutaneous) and 0PHL44Z (percutaneous endoscopic).

With a different device, use 0PHL05Z (external fixation device), 0PHL06Z (internal fixation device, intramedullary), 0PHL08Z (external fixation device, limb lengthening), 0PHL0BZ (external fixation device, monoplanar), 0PHL0CZ (external fixation device, ring) and 0PHL0DZ (external fixation device, hybrid).

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.
