When to Use

Use a code from this group when an existing device on a facial bone is removed and an identical or similar device is reinserted on the same facial bone without open incision or puncture. These codes apply only when the procedure is performed in an inpatient setting and meets the described root operation and body part criteria.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
0N2WX0Z	Change Drainage Device in Facial Bone, External Approach
0N2WXYZ	Change Other Device in Facial Bone, External Approach

Typical Clinical Scenarios

An elderly patient with a previously placed external facial fracture drainage tube after a complex zygomaticomaxillary fracture presents with new onset blockage and persistent serous drainage; the inpatient team determines the external drainage device must be removed and an identical external drainage device reinserted to restore proper drainage without performing an open incision or entering a mucous membrane. A device change is performed at the bedside or in the procedure area under monitored anesthesia in the hospital to manage potential infection risk and ensure fracture site drainage. Typical codes: 0N2WX0Z
A middle-aged patient admitted electively for hardware management following healing of a mandibular fracture has a superficial external fixation pin site with loosening of an external facial stabilization device; the plan is to take off the existing external stabilization/other noninternal device and replace it with a similar external device to maintain alignment while avoiding repeat open surgical exposure. The procedure is done during the inpatient stay to secure the facial bone alignment and facilitate ongoing inpatient postoperative care. Typical codes: 0N2WXYZ
A young adult who sustained facial trauma with an external drainage device placed at an outside hospital develops device malfunction and recurrent soft-tissue swelling while inpatient; because the facial bone device is malfunctioning but there is no need for open debridement or entering a mucous membrane, the team elects to change the external drainage device to an identical device to re-establish function and monitor for resolution of swelling. Typical codes: 0N2WX0Z, 0N2WXYZ
