Operation Definition

Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device

Procedure Overview

Revision procedures address a device already implanted in the skin or breast that is no longer working correctly or has shifted out of position, without fully replacing it. This covers situations such as repositioning a displaced breast implant, adjusting or repairing a malfunctioning tissue expander, or correcting a poorly seated dermal graft carrier. The goal is to restore proper function or placement using the existing device to the extent that is medically possible.

People need this type of procedure when they experience implant malposition, capsular contracture affecting device function, expander port problems, or other mechanical device issues discovered on exam or imaging. Surgeons evaluate whether the existing device can be salvaged and repositioned or repaired in place, which is generally a less extensive undertaking than removing and starting over with new hardware.

Anatomy & Axis Detail

Breast, Left

Revision of the left breast addresses complications from a previous procedure on that side, such as implant rupture, malposition, or capsular contracture, or failure of a reconstructive flap or graft to heal as intended. Indications range from correcting bottoming-out or rippling after augmentation to managing partial flap loss or fat necrosis following autologous reconstruction, and the underlying cause, whether mechanical device failure, infection, or asymmetric scarring, shapes the specific technique used. Because breast surgical history is frequently asymmetric between sides, especially after unilateral mastectomy or trauma, the left breast may carry a distinct implant type, flap source, or timeline that must be documented separately from the right. Revision coding here reflects a corrective intervention on an existing device or repair rather than the introduction of new material or a full replacement 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.

Device: Nonautologous Tissue Substitute

Nonautologous Tissue Substitute refers to biologic material sourced from a donor or another species, such as an allograft or xenograft, used to replace a body part. It differs from Autologous Tissue Substitute by tissue origin outside the patient's own body, and from Synthetic Substitute by being biologic rather than manufactured material.

Coding & Documentation

Correct assignment depends on documentation clearly stating that a device already in place was corrected, adjusted, or repositioned rather than removed and swapped for a new one. The note should describe the specific problem found, such as displacement, malfunction, or a leaking or deflated component, and confirm the same device remained after the procedure. A common error is applying Revision when the surgeon actually removed the old device entirely and inserted a brand-new one, which is coded as Removal combined with Replacement or Insertion, not Revision. Coders also sometimes overlook Revision when a note uses casual language like "repositioned the implant" without stating the device stayed in place, so it is worth confirming the device identity did not change before finalizing the code.

Commonly Confused With

ReplacementReplacement is the key distinction, since it involves taking out the malfunctioning device and putting in a new one, while Revision keeps the original device and only corrects its position or function.
RemovalRemoval alone is used when a device is taken out with no repair or replacement performed in the same operative episode, which differs from Revision's requirement that correction actually occurs.
