Operation Definition
Taking out or off a device from a body part
Procedure Overview
This family covers taking out a device that was previously placed in a lymphatic or hemic structure, such as a drain left in the splenic bed after surgery, a catheter used to manage a lymphatic leak, or a mesh or other implant associated with the spleen or thymus. The device itself is being removed; no tissue is being cut away or repaired in the process. These procedures are typically staged after an earlier operation, once the device has served its purpose - controlling drainage, supporting healing, or monitoring a surgical site.
For patients, this is usually a straightforward, low-risk step in recovery rather than a major operation, though it is still coded as a distinct procedure because it involves entering the body to retrieve the device.
Anatomy & Axis Detail
Bone Marrow
Bone marrow, the soft tissue within the medullary cavities of bones responsible for producing blood cells, is removed here as a discrete cutting-out procedure rather than through aspiration, typically involving surgical excision of marrow-containing bone tissue for biopsy, tumor evaluation, or specific therapeutic indications. This differs from percutaneous marrow aspiration or biopsy performed with a needle, which is generally captured elsewhere as an extraction procedure rather than excision. Because marrow is distributed throughout the axial and long bones, the specific site sampled or excised, such as the iliac crest or sternum, matters clinically even though the body part value itself is not further subdivided by location. Documentation should make clear that tissue was surgically cut out rather than aspirated, since the technique determines which root operation applies.
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: 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
Coders need documentation identifying the specific device removed and confirming that removal is the entire action - if the surgeon also repairs tissue, replaces the device, or performs any other procedure during the same encounter, additional codes are needed alongside or instead of Removal. A frequent error is coding Removal when a device is actually being exchanged for a new one in the same body part; ICD-10-PCS handles a straight swap differently than a removal followed by a separate insertion. Another pitfall is confusing removal of a device from the lymphatic system with removal of a device from an adjacent structure (such as a vascular access line running near lymph nodes) - the device must be recorded against the lymphatic or hemic body part it was actually seated in.
