Operation Definition
Cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part
Procedure Overview
Division procedures in the lower bones involve cutting into a bone to separate or transect it, without draining any fluid or gas in the process. The clearest example is an osteotomy performed to realign a deformed limb - cutting through the femur, tibia, or another lower bone so the two segments can be repositioned into better alignment, often before fixation hardware holds the new position in place.
These procedures are used for correcting angular deformities, lengthening or shortening a limb segment, or releasing a bony bridge such as a growth plate bar that is restricting normal bone growth in a child.
Anatomy & Axis Detail
Lower Femur, Left
On the left side, the lower femur forms the distal thigh bone just proximal to the knee joint, a region prone to growth-related angular deformities and post-traumatic malalignment. Dividing this segment means transecting the bone to create separate pieces, commonly to correct varus or valgus angulation, to shorten or derotate the limb, or to release a fused or malformed segment. The proximity to the growth plate in younger patients and to the popliteal vessels posteriorly makes the plane of division a key technical detail, often guided by imaging to protect adjacent soft tissue. Since division alone does not include reduction or hardware placement, coders should confirm from the operative note that no material was removed and that any subsequent stabilization is captured as a distinct procedure.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
Coders should confirm the note describes cutting the bone through its full thickness to separate it into distinct segments, distinguishing it from a partial cut or notch. If the surgeon also placed fixation hardware to hold the newly divided bone in position, that stabilization step is coded separately as Insertion in addition to the Division.
A frequent mistake is coding Division when the intent and outcome was actually a fusion - if the bone segments were subsequently joined together, Fusion may be the more accurate root operation for that portion of the procedure. Coders should also avoid defaulting to Division for procedures where fluid was drained as part of the cut, since draining changes the root operation to Drainage.
