About 0PHN44Z

0PHN44Z is the ICD-10-PCS code for a insertion procedure on the left carpal using a percutaneous endoscopic 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, carpals and metacarpals, the ICD-9-CM procedure title it maps to (78.54).

For a different body part, codes include 0PH044Z (sternum), 0PH144Z (ribs, 1 to 2), 0PH244Z (ribs, 3 or more), 0PH344Z (cervical vertebra), 0PH444Z (thoracic vertebra), 0PH544Z (right scapula) and 20 more.

The same procedure with a different approach is coded 0PHN04Z (open) and 0PHN34Z (percutaneous).

With a different device, use 0PHN45Z (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.
