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
This Change family covers taking an existing device out of a body orifice, such as the mouth, nasal passage, or another natural opening, and replacing it with an identical or similar device at the same encounter, all without cutting or puncturing skin or mucous membrane. Common examples include swapping out a nasogastric tube, a vaginal packing device, or a similar orifice-based appliance for a fresh one.
This kind of exchange is routine maintenance care rather than a new therapeutic intervention: the original device already served its purpose in placing or supporting something at that orifice, and the change simply keeps that function going by refreshing the device on a regular schedule or when the existing one becomes soiled, worn, or blocked.
Because the exchange happens through the orifice's natural opening rather than through a surgical incision, it is classified as a non-invasive bedside or outpatient procedure, distinct from device placements that require cutting into tissue.
Anatomy & Axis Detail
Ear
Change procedures at the ear orifice involve replacing a wick, packing strip, or drainage device seated in the external auditory canal, most often for otitis externa, post-tympanostomy drainage, or after mastoid surgery when a canal dressing keeps the operative site open and medicated. The external canal's narrow, curved shape and its proximity to the tympanic membrane make careful visualization with an otoscope or microscope necessary before removing the old material, since surrounding tissue is delicate and easily abraded. Ear wicks in particular expand when saturated with topical antibiotic solution and must be exchanged on a schedule to maintain drug delivery. The procedure is performed through the natural canal opening, and coding is specific to whichever ear is treated.
Approach: External
External is the only approach value used in the Placement section, since every placement procedure, such as applying a cast, splint, packing, or pressure dressing, is performed on the skin or an accessible mucous membrane without penetrating instrumentation. It simply confirms that these body-alteration-free interventions occur entirely at or on the body surface, with no internal route to distinguish it from.
Device: Packing Material
Packing Material is placed within a body cavity or wound in the Placement section to control bleeding, obliterate dead space, or absorb drainage, such as nasal or wound packing. It works by direct contact within an opening rather than external wrapping. It is distinguished from a Pressure Dressing, which is applied over the surface of a wound, and from a Bandage, which secures rather than fills a space.
Coding & Documentation
Coders should look for documentation confirming both halves of the exchange, removal of the old device and insertion of a new, identical or similar one, at the orifice named, along with confirmation that no incision or puncture was involved. A note describing only removal, or only insertion, does not support this code by itself.
A common error is applying this code when a device is placed in an orifice for the very first time, which belongs under Insertion or Placement rather than Change, since Change presumes a prior device is already present. Coders also sometimes miscode the orifice, particularly when a device sits at the junction of two anatomically adjacent openings.
Commonly Confused With
This family is easily confused with Removal alone, which applies when a device is taken out without a new one going back in, and with Insertion, which applies to the first-time placement of a device rather than a routine swap. It is also distinct from the anatomical regions Change procedures, which apply the same replacement concept to external body regions rather than natural orifices.
