Operation Definition
Taking out or off a device from a body part and putting back an identical or similar device in or on the same body part without cutting or puncturing the skin or a mucous membrane
Procedure Overview
A Change procedure swaps out a device already in place in the mouth or throat for a new one of the same or similar type, without any incision or puncture. In this body system it applies almost exclusively to externally accessible devices such as feeding tubes or drains positioned at the mouth or throat opening, where the old device is simply withdrawn through the existing tract and a fresh one inserted in its place.
Patients encounter this procedure when a long-term device needs routine replacement due to wear, blockage, or scheduled maintenance, not because of a new medical problem. It is a low-risk, often outpatient exchange rather than a corrective surgery.
Anatomy & Axis Detail
Larynx
The larynx houses the vocal folds and serves as the gateway to the lower airway, making it a common site for temporary device placement when airway patency or voice function must be supported. A Change procedure on the larynx involves removing an existing device, such as a laryngeal stent or airway prosthesis, and replacing it with a new one of the same type through the natural or existing orifice, without making a new incision. This is typically performed in patients with laryngeal stenosis, post-surgical stenting, or vocal fold pathology requiring periodic device maintenance. Because the larynx is essential for both breathing and voice production, device changes here must preserve airway patency throughout the exchange, and documentation should confirm the replacement device is of the same type as the one removed.
Approach: External
External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.
Device: Other Device
Other Device is a catchall value used when a device remains in place but does not fit any of the specifically defined categories, such as tissue substitutes, drainage tubes, radioactive elements, or monitoring sensors. It allows coding of implanted or inserted devices that fall outside those named classifications.
Coding & Documentation
Coding a Change requires documentation that the device was removed and replaced during the same encounter, entirely through the natural or existing opening, with no cutting of skin or mucous membrane. The approach value is always External for this root operation, so the coder should not look for an approach involving instrumentation through an incision. A frequent mistake is applying Change when a clinician actually performed a more involved revision requiring dissection, which should instead be captured under Revision or Removal followed by Insertion. Another pitfall is coding routine tube flushing or repositioning, which does not meet the definition of Change since no device was actually taken out and replaced.
