About 0RJM4ZZ

0RJM4ZZ is the ICD-10-PCS code for a inspection procedure on the left elbow joint using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Arthroscopy, elbow, the ICD-9-CM procedure title it maps to (80.22).

For a different body part, codes include 0RJ04ZZ (occipital-cervical joint), 0RJ14ZZ (cervical vertebral joint), 0RJ34ZZ (cervical vertebral disc), 0RJ44ZZ (cervicothoracic vertebral joint), 0RJ54ZZ (cervicothoracic vertebral disc), 0RJ64ZZ (thoracic vertebral joint) and 22 more.

The same procedure with a different approach is coded 0RJM0ZZ (open), 0RJM3ZZ (percutaneous) and 0RJMXZZ (external).

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.
