About 0RH004Z

0RH004Z is the ICD-10-PCS code for a insertion procedure on the occipital-cervical joint using an open 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 other arthrotomy, other specified sites, the ICD-9-CM procedure title it maps to (80.19).

For a different body part, codes include 0RH104Z (cervical vertebral joint), 0RH404Z (cervicothoracic vertebral joint), 0RH604Z (thoracic vertebral joint), 0RHA04Z (thoracolumbar vertebral joint), 0RHC04Z (right temporomandibular joint), 0RHD04Z (left temporomandibular joint) and 18 more.

The same procedure with a different approach is coded 0RH034Z (percutaneous) and 0RH044Z (percutaneous endoscopic).

With a different device, use 0RH003Z (infusion device), 0RH008Z (spacer), 0RH00BZ (spinal stabilization device, interspinous process), 0RH00CZ (spinal stabilization device, pedicle-based) and 0RH00DZ (spinal stabilization device, facet replacement).

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 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 “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
