About 0SH644Z

0SH644Z is the ICD-10-PCS code for a insertion procedure on the coccygeal joint using a percutaneous endoscopic 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 0SH044Z (lumbar vertebral joint), 0SH344Z (lumbosacral joint), 0SH544Z (sacrococcygeal joint), 0SH744Z (right sacroiliac joint), 0SH844Z (left sacroiliac joint), 0SH944Z (right hip joint) and 13 more.

The same procedure with a different approach is coded 0SH604Z (open) and 0SH634Z (percutaneous).

With a different device, use 0SH643Z (infusion device) and 0SH648Z (spacer).

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.
