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

External Ear, Right

The right external ear, comprising the auricle and its cartilaginous framework, is repositioned when it has been displaced from its normal anatomic location, as occurs with traumatic avulsion injuries, congenital deformities like prominent or lop ear, or after certain reconstructive stages following microtia repair. Because auricular cartilage is elastic but easily deformed, repositioning often involves suture anchoring or cartilage-sparing techniques to move the structure back into correct alignment without devascularizing the skin envelope. Otoplasty procedures performed to correct protruding ears are a common example, where the cartilage is reshaped and moved closer to the scalp. Documentation should clarify whether the procedure moved existing native tissue to a new position, which supports Reposition, versus cases where tissue was excised or grafted, which would be coded differently.

Approach: Open

Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.

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.

Commonly Confused With

ReplacementReposition is often confused with Replacement, since both can involve manipulating displaced anatomy, but Replacement requires excising the original part and inserting a substitute while Reposition simply moves the existing structure.
RevisionIt also overlaps conceptually with Revision, which corrects a malfunctioning device rather than native anatomy - repositioning a displaced septal implant is Revision, while repositioning the patient's own septal cartilage is Reposition.
