Operation Definition
Cutting off all or a portion of the upper or lower extremities
Procedure Overview
This family covers amputation procedures of the lower extremity - removing all or part of a leg, thigh, knee, ankle, or foot when the limb can no longer be saved or is causing life-threatening harm. Common reasons include severe peripheral vascular disease that has cut off blood flow, uncontrolled diabetic infection, tissue death from trauma, malignant tumors, or crushing injuries where reconstruction isn't possible. The level chosen - above the knee, below the knee, through the ankle, or partial foot - depends on how much healthy, well-perfused tissue remains and how well the residual limb will support a prosthesis afterward.
Recovery involves wound healing, pain management, and eventually fitting for a prosthetic device and rehabilitation to relearn mobility. Surgeons try to preserve as much functional length as possible while ensuring the remaining tissue has adequate blood supply to heal.
Anatomy & Axis Detail
Femoral Region, Right
The femoral region refers to the hip and upper thigh area encompassing the hip joint and proximal femur, so detachment at this level is typically a hip disarticulation performed through the joint capsule without cutting the pelvic bone itself, distinguishing it from a hindquarter procedure. It is indicated when tumor, infection, or vascular compromise involves the femur too close to the hip for a standard above-knee amputation to achieve adequate margins while still sparing the pelvis. The surgeon disarticulates the femoral head from the acetabulum and ligates the femoral vessels near their origin, preserving the pelvic girdle intact. Because no femoral shaft remains, prosthetic options rely on a socket that captures the pelvis rather than a conventional above-knee fitting, which affects rehabilitation planning.
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
Coders assign Detachment codes based on the specific anatomical level documented in the operative note - the body part value distinguishes 1st ray, 2nd through 5th ray, foot, ankle, lower leg, knee, upper leg, and hip disarticulation, so the note must state the exact bone or joint level transected. The qualifier further specifies complete versus high or low variants at some levels. A frequent error is defaulting to a generic 'leg amputation' code when the documentation actually supports a more precise ray- or joint-level qualifier, or missing that a revision amputation (converting a failed below-knee stump to above-knee) is coded as a new Detachment procedure at the higher level rather than an Excision.
