Typical codes: 0C2YX0Z
A hospitalized postoperative head and neck cancer patient with a temporary oral wound pack or externally applied oral appliance that becomes contaminated or malpositioned undergoes bedside removal and replacement of the external mouth device to maintain wound protection and topical therapy without cutting mucosa. Typical codes: 0C2YXYZ, 0C2YX0Z
A patient in the emergency observation unit with acute traumatic facial swelling after a fall has an externally placed oral device (e.g., oral splint or drain) changed because of malfunction or patient intolerance; clinicians remove the prior external device and apply an equivalent external device to preserve oral function and avoid immediate surgical intervention.
