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 that was previously placed in the lymphatic and hemic system and is no longer working as intended or has moved out of position, and the surgeon corrects the problem without fully removing and replacing the device. In practice this arises with implanted devices used to manage lymphatic complications, such as a clip or mechanical closure device placed around the thoracic duct that has slipped, loosened, or otherwise failed to control a chyle leak as originally intended. Repositioning or adjusting that device to restore its function falls into this family.
Because implanted lymphatic devices are uncommon compared to those used elsewhere in the body, this family is used less frequently than Revision families in other body systems, but the clinical logic is the same: correct what exists rather than start over.
Anatomy & Axis Detail
Bone Marrow
Bone marrow is the soft tissue within the medullary cavities of bones responsible for hematopoiesis, and procedures on it most often relate to biopsy, aspiration, or harvest for transplantation rather than device placement, making revision an uncommon but specific scenario. Revision would apply, for example, to correcting a malfunctioning intraosseous access device or a marrow-harvest-related complication requiring surgical correction at the access site, such as a hematoma or malpositioned cannula left from a prior procedure. Because marrow procedures are typically performed at accessible sites like the posterior iliac crest or sternum, revision is generally a localized, minimally invasive correction rather than an extensive surgical undertaking. Coders should distinguish revision, which fixes a prior device or procedural outcome, from routine repeat aspiration or biopsy, which would use a different root operation entirely.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Device: Drainage Device
Drainage Device denotes a device such as a tube or catheter left in place to remove fluid, blood, or air from a body part or cavity following a procedure. It is distinguished from Monitoring Device, which senses and records physiologic data rather than evacuating substances from the body.
Coding & Documentation
A coder should confirm the note describes fixing or repositioning a device that was already in place, rather than removing it entirely and inserting a new one. Documentation needs to identify both the device being revised and the specific problem being corrected, such as displacement or malfunction. The most common error is coding Removal followed by a fresh insertion when the surgeon actually adjusted the existing device in place, which should be captured as a single Revision instead.
