About 0RJB4ZZ

0RJB4ZZ is the ICD-10-PCS code for a inspection procedure on the thoracolumbar vertebral disc 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, other specified sites, the ICD-9-CM procedure title it maps to (80.29).

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 0RJB0ZZ (open), 0RJB3ZZ (percutaneous) and 0RJBXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. 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 “Other Musculoskeletal System and Connective Tissue O.R. 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.
