0N2BX0Z	Change Drainage Device in Nasal Bone, External Approach
0N2BXYZ	Change Other Device in Nasal Bone, External Approach

Typical Clinical Scenarios

An elderly patient with a chronic external nasal stent used to support a healing nasal bone fracture presents for planned inpatient replacement because the original stent has degraded and no longer fits properly; the device is removed and an identical external nasal stent is placed without incision. Typical codes: 0N2BX0Z
A pediatric patient who sustained nasal bone trauma with an external splint applied in the emergency department returns to the hospital for an inpatient procedure to exchange the temporary external splint for a new, similar external device to maintain alignment during healing; the old device is taken off and a like device is applied without cutting the skin. Typical codes: 0N2BX0Z
An adult with an exposed external fixation dressing over the nasal bone after prior conservative management develops device-related irritation and requires inpatient device change to prevent skin breakdown; the clinician removes the existing external device and replaces it with a similar external device at the bedside without puncturing the mucosa. Typical codes: 0N2BX0Z, 0N2BXYZ
