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
Hair
Hair as a coded body part applies to correcting a prior procedure involving hair-bearing tissue, most commonly a hair transplant or scalp reduction that has produced an unsatisfactory result, such as poor graft take, unnatural growth pattern, or a device complication from an implanted hair-bearing flap. This is distinct from performing a new transplant, since Revision presumes an earlier intervention exists and requires correction rather than initial placement of grafts. Surgeons may need to reposition follicular unit grafts, address scarring at a prior donor or recipient site, or manage an infected or malpositioned tissue expander used in scalp reconstruction. Because outcomes in hair restoration are highly visible and cosmetically sensitive, the operative note typically details what aspect of the original procedure failed and what corrective technique was used to address it.
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: Autologous Tissue Substitute
Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of 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.
