About 0PHK4DZ
0PHK4DZ is the ICD-10-PCS code for a insertion procedure on the right ulna using a percutaneous endoscopic approach with external fixation device, hybrid. 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 application of external fixator device, radius and ulna and application of hybrid external fixator device, the ICD-9-CM procedure titles it maps to (78.13 and 84.73).
For a different body part, codes include 0PHC4DZ (right humeral head), 0PHD4DZ (left humeral head), 0PHF4DZ (right humeral shaft), 0PHG4DZ (left humeral shaft), 0PHH4DZ (right radius), 0PHJ4DZ (left radius) and 1 more.
The same procedure with a different approach is coded 0PHK0DZ (open) and 0PHK3DZ (percutaneous).
With a different device, use 0PHK44Z (internal fixation device), 0PHK45Z (external fixation device), 0PHK46Z (internal fixation device, intramedullary), 0PHK48Z (external fixation device, limb lengthening), 0PHK4BZ (external fixation device, monoplanar) and 0PHK4CZ (external fixation device, ring).
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.
