About 0Q9K4ZZ

0Q9K4ZZ is the ICD-10-PCS code for a drainage procedure on the left fibula using a percutaneous endoscopic 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, tibia and fibula, the ICD-9-CM procedure title it maps to (77.17).

For a different body part, codes include 0Q904ZZ (lumbar vertebra), 0Q914ZZ (sacrum), 0Q924ZZ (right pelvic bone), 0Q934ZZ (left pelvic bone), 0Q944ZZ (right acetabulum), 0Q954ZZ (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0Q9K0ZZ (open) and 0Q9K3ZZ (percutaneous).

With a different device, use 0Q9K40Z (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) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical category “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”.

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