Operation Definition
Moving to its normal location, or other suitable location, all or a portion of a body part
Procedure Overview
Reposition procedures move an ear, nose, or sinus structure from an abnormal location back to where it belongs, or to another location where it will function properly, without removing or replacing any tissue. Septoplasty is the classic example: a deviated nasal septum is straightened and moved back toward the midline to relieve nasal obstruction, typically by freeing the cartilage and bone from surrounding attachments and repositioning them without excising the septum itself. Displaced nasal fractures are corrected the same way, and dislocated or malpositioned ossicles in the middle ear can be repositioned during exploratory surgery.
These procedures are usually performed to correct either a congenital deviation, an old injury that healed poorly, or a structure that shifted after a prior operation. Because nothing is removed, recovery tends to be shorter than resection or replacement procedures, though nasal packing or splinting is often used afterward to hold the corrected position while healing occurs.
Anatomy & Axis Detail
Eustachian Tube, Left
The left eustachian tube links the middle ear space to the nasopharynx and is responsible for pressure equalization and mucus clearance, functions that depend on its cartilaginous framework maintaining a normal course and orientation. Reposition of this structure is rarely performed but may be documented in the context of skull base or craniofacial reconstructive surgery where the tubal orifice or supporting cartilage has been displaced by trauma or a congenital anomaly and is surgically returned to its correct anatomic alignment. Given the tube's proximity to the internal carotid artery and skull base foramina, such procedures demand precise anatomic knowledge. Coders should distinguish true repositioning of tubal tissue from the more commonly performed balloon dilation of a stenotic eustachian tube, which falls under a different root operation.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
Coding & Documentation
Coders assign Reposition when the documentation makes clear the surgeon relocated the body part without excising or replacing tissue - for septoplasty, that means confirming cartilage and bone were repositioned rather than removed, since some septoplasty techniques do resect a strip of cartilage, which would instead point toward Excision or a combination of root operations. The operative note's description of technique (submucous resection versus straightening and repositioning) drives the code choice.
A common mistake is coding all septoplasty the same way regardless of whether tissue was trimmed and discarded; another is failing to recognize that closed reduction of a nasal fracture, done percutaneously without an open approach, still qualifies as Reposition under the applicable approach value. Coders should also watch for combination procedures where reposition of the septum is paired with resection of a spur or supplement with a spreader graft, each needing its own code.
