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 family covers procedures in which a device already in place within the female reproductive tract - most often a vaginal pessary, a cervical cerclage device, or an intrauterine device placed for reasons other than pure insertion - is removed and replaced with a new one of the same or a similar type, without any incision or puncture. The device itself is not being changed in design or function; it is simply being swapped out because it has reached the end of its recommended wear time, has become soiled or degraded, or needs to be resized as a patient's anatomy shifts over time.
Patients encounter this most commonly with pessary management for pelvic organ prolapse, where a silicone ring or other support device sits in the vagina and needs periodic exchange, typically every few months, to prevent irritation, odor, or erosion of the vaginal wall. Because the procedure is done through the natural vaginal canal rather than through a cutting or puncturing approach, it is usually quick, performed in an outpatient or office setting, and does not require anesthesia beyond local comfort measures.
Anatomy & Axis Detail
Ovary
The ovary is the paired gonad responsible for oocyte maturation and hormone production, and a device is changed at this site almost exclusively in the context of a temporary catheter, drain, or packing left after a procedure such as cyst aspiration, abscess drainage, or torsion management rather than a permanent implant. Because ovarian tissue is small, mobile, and closely associated with the fallopian tube and infundibulopelvic ligament, exchanging an external device here requires care to avoid dislodging or twisting the adnexa. The change is performed without cutting or puncturing the skin or mucous membrane, distinguishing it from procedures that access the ovary surgically. Clinical documentation should clarify what device was removed and replaced, since ovarian device changes are uncommon and are typically tied to short-term postoperative drainage management rather than long-term therapy.
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
A coder should look for documentation confirming that an existing device was removed and an identical or similar device was reinserted in the same body part, entirely through a natural or previously existing opening. The note should specify the device type (for example, pessary size and style) and confirm no incision was made - if the clinician performed any cutting or dissection to access the site, Change is the wrong root operation. The most frequent assignment error is choosing Change when the device is actually being upgraded to a different type or when the encounter is a first-time placement, which belongs under Insertion instead. Coders should also confirm the approach is coded as External, since Change procedures by definition bypass the skin and mucous membrane.
