About 0QHY4MZ

0QHY4MZ is the ICD-10-PCS code for a insertion procedure on the lower bone using a percutaneous endoscopic approach with bone growth stimulator. 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 insertion of bone growth stimulator, femur, insertion of bone growth stimulator, patella, insertion of bone growth stimulator, tibia and fibula and 2 more, the ICD-9-CM procedure titles it maps to (78.95, 78.96, 78.97 and 2 more).

The same procedure with a different approach is coded 0QHY0MZ (open) and 0QHY3MZ (percutaneous).

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.
