About 0Q9F0ZZ
0Q9F0ZZ is the ICD-10-PCS code for a drainage procedure on the left patella using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other incision of bone without division, patella, the ICD-9-CM procedure title it maps to (77.16).
For a different body part, codes include 0Q900ZZ (lumbar vertebra), 0Q910ZZ (sacrum), 0Q920ZZ (right pelvic bone), 0Q930ZZ (left pelvic bone), 0Q940ZZ (right acetabulum), 0Q950ZZ (left acetabulum) and 18 more.
The same procedure with a different approach is coded 0Q9F3ZZ (percutaneous) and 0Q9F4ZZ (percutaneous endoscopic).
With a different device, use 0Q9F00Z (drainage device).
It is an operating-room procedure in the MS-DRG logic for DRG 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC), DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur 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 “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”, “Other O.R.

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