Moving to its normal location, or other suitable location, all or a portion of a body part

Procedure Overview

Reposition procedures move skin or breast tissue to a different location while leaving it attached to its original blood and nerve supply, unlike a graft or implant that is placed anew. A well-known example is breast reduction or mastopexy, where breast tissue and the nipple-areolar complex are relocated to a higher, more natural position on the chest wall to correct sagging or asymmetry.

These procedures are performed for both functional and aesthetic reasons: correcting a displaced nipple after trauma, repositioning breast tissue during reduction surgery to relieve back and neck strain from excess weight, or moving misplaced skin folds. The tissue itself is not removed from the body or replaced with something new; it is simply relocated to where it functions or appears more normally.

Because the tissue keeps its own blood supply during relocation, these procedures generally carry a lower risk of tissue death compared to a free graft, and healing tends to be more predictable.

Anatomy & Axis Detail

Breast, Right

Repositioning the right breast refers to moving the breast mound, or a significant portion of it, to a new anatomic location without removing or replacing tissue, most commonly to correct ptosis (sagging) through mastopexy or to relocate breast tissue during staged reconstructive procedures. The breast is supported by fibrous Cooper's ligaments and skin envelope, both of which are altered when the gland is elevated and resecured higher on the chest wall; this differs from reduction mammoplasty, which combines tissue excision with repositioning and is coded separately. Surgeons document the vector and degree of elevation, whether the nipple-areolar complex moved with the gland on a pedicle, and any skin resection performed concurrently, since these details determine whether reposition alone or a combination of root operations best represents the procedure.

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

The operative note needs to describe the tissue being moved and its new anatomic location, distinguishing a true repositioning of existing tissue from a repair that simply closes a wound in place. Coders should confirm that the tissue retained its original attachments and blood supply during the move, since a flap that is completely detached and reattached to a new site with vessel reconnection may be coded differently.

A common error is defaulting to Repair for a breast reduction or mastopexy, when the primary intent of relocating the nipple-areolar complex or breast mound is more accurately captured as Reposition. Coders should also watch for cases where excess skin or tissue is excised as part of the same operation, which requires an additional Excision code alongside Reposition, since removing tissue and repositioning tissue are distinct root operations performed in the same encounter.

Commonly Confused With

TransferReposition is frequently confused with Transfer, which also relocates tissue while preserving its blood supply, but Transfer moves tissue to a different body part to serve a new function, such as covering a defect elsewhere, while Reposition moves tissue within essentially the same body part to correct its position.
RepairIt is also distinct from Repair, which restores tissue that has been disrupted rather than intentionally relocating normally positioned tissue for a therapeutic goal.
ExcisionWhen breast reduction includes both tissue removal and repositioning of the remaining mound, coders should recognize that both Excision and Reposition may need to be captured rather than one root operation alone.
