About 0QHD04Z

0QHD04Z is the ICD-10-PCS code for a insertion procedure on the right patella 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 internal fixation of bone without fracture reduction, patella, the ICD-9-CM procedure title it maps to (78.56).

For a different body part, codes include 0QH004Z (lumbar vertebra), 0QH104Z (sacrum), 0QH204Z (right pelvic bone), 0QH304Z (left pelvic bone), 0QH404Z (right acetabulum), 0QH504Z (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QHD34Z (percutaneous) and 0QHD44Z (percutaneous endoscopic).

With a different device, use 0QHD05Z (external fixation device).

It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection 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 “Knee Procedures with Principal Diagnosis of Infection”, “Knee Procedures without Principal Diagnosis of Infection”, “Other O.R. Procedures for Injuries” and 1 more.

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