About 0PNJ4ZZ
0PNJ4ZZ is the ICD-10-PCS code for a release procedure on the left radius using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to other repair or plastic operations on bone, radius and ulna, the ICD-9-CM procedure title it maps to (78.43).
For a different body part, codes include 0PN04ZZ (sternum), 0PN14ZZ (ribs, 1 to 2), 0PN24ZZ (ribs, 3 or more), 0PN34ZZ (cervical vertebra), 0PN44ZZ (thoracic vertebra), 0PN54ZZ (right scapula) and 20 more.
The same procedure with a different approach is coded 0PNJ0ZZ (open) and 0PNJ3ZZ (percutaneous).
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.
