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devices such as feeding tubes or drains positioned at the mouth or throat opening, where the old device is simply withdrawn through the existing tract and a fresh one inserted in its place.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
Salivary Gland
The salivary glands, comprising the parotid, submandibular, and sublingual glands, produce saliva that aids in digestion, lubrication, and oral protection, and are drained by ducts opening into the oral cavity. A Change procedure on a salivary gland involves exchanging a device, such as a stent or drain placed within a salivary duct or gland, for a new one without cutting or puncturing the skin or mucosa to access the site, typically performed through the existing external opening. This procedure is relevant in the management of chronic sialadenitis, ductal stricture, or postoperative drainage where an indwelling device requires periodic replacement. Because salivary ducts are narrow and the surrounding glandular tissue is delicate, device changes rely on the existing access route, and documentation should confirm the device was exchanged through the original opening without new incision.
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
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.
