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 in the respiratory system involves removing a device already in place, such as a tracheostomy tube, and replacing it with a new one of the same or similar type, without cutting or puncturing tissue. Because the opening already exists from a prior procedure, the exchange happens through the established tract, making it a lower-intensity intervention than the original surgery that created the airway.
This type of procedure is performed routinely to prevent tube blockage from dried secretions, to replace a tube that has become damaged or ill-fitting, or to upsize or downsize a tracheostomy tube as a patient's clinical needs change over time. It is a maintenance step rather than a new surgical intervention.
Anatomy & Axis Detail
Tracheobronchial Tree
The tracheobronchial tree encompasses the trachea together with the branching bronchi that conduct air into the lungs, and this body part value applies when a device positioned across multiple levels of that airway, such as an airway stent spanning the trachea and a mainstem bronchus, is removed and a new one put in its place. Because such devices bridge more than one distinct anatomic segment, they are coded to the tracheobronchial tree rather than to trachea or bronchus alone. Airway stents in this region are typically placed to relieve extrinsic compression or malacic collapse from tumor, prior surgery, or chronic disease, and exchanging them requires bronchoscopic visualization to confirm proper seating without migration or mucosal injury during the swap.
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: Drainage Device
Drainage Device denotes a device such as a tube or catheter left in place to remove fluid, blood, or air from a body part or cavity following a procedure. It is distinguished from Monitoring Device, which senses and records physiologic data rather than evacuating substances from the body.
Coding & Documentation
Coders should confirm that the documentation describes a device swap through an existing opening, not a new incision or dilation of the tract. Notes stating "tracheostomy tube changed" or "exchanged for a smaller/larger tube at bedside" typically support this code. A frequent error is applying Change when the tract had to be redilated or surgically revised, since that additional manipulation may point to a different root operation. Another pitfall is coding routine tube changes performed outside a procedural encounter, which may not need a separate procedure code depending on setting.
Commonly Confused With
Change is distinct from Removal, which takes a device out without putting a replacement in, and from Bypass or Drainage procedures that create or modify the tract itself. The key distinction is that Change never involves cutting or puncturing skin or mucous membrane; if the tract needs surgical revision, a different root operation applies.
