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 upper bones cut through bone without draining fluid or gas, separating the bone into two segments to change its alignment, length, or shape. In the upper extremity this most often applies to osteotomies of the clavicle, scapula, humerus, radius, or ulna performed to correct a deformity, realign a malunited fracture, or shorten or lengthen a bone as part of a reconstructive plan.

Surgeons choose this approach when the goal is purely to cut and separate bone, with any repositioning, fixation, or realignment carried out as a distinct step afterward. It differs fundamentally from cutting to drain an abscess or hematoma, since Division applies only when the purpose is structural separation of the bone itself.

Anatomy & Axis Detail

Humeral Shaft, Left

The left humeral shaft, the tubular diaphysis running between the shoulder and elbow, is divided when a corrective osteotomy is needed for angular or rotational malalignment from a prior fracture, or to intentionally shorten or lengthen the arm in staged reconstructive procedures. The dense cortical bone of the shaft usually requires mechanical cutting instruments, and the surgeon must account for the radial nerve's course along the spiral groove to avoid injury during the cut. Because division preserves all bone rather than removing a wedge, the resulting fragments can be rotated or translated into corrected alignment and then stabilized with plates, rods, or external fixation, making the plane and level of the cut an important detail in the procedure documentation.

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.

Coding & Documentation

Coding from this family requires operative documentation describing an osteotomy or bone cut performed to separate the bone, without a stated purpose of draining fluid. If the same procedure also repositions or realigns the bone fragments, coders must recognize that the corrective step is typically captured with a separate root operation such as Reposition, while Division applies to the cutting step itself when it stands alone or is not inherent to the reposition.

The most common error is coding a fracture reduction or corrective osteotomy entirely as Division when the operative note actually describes realignment and fixation, which should be coded as Reposition since that root operation includes the necessary cutting. Coders should reserve Division for cases where cutting and separating the bone is the complete objective, such as creating a controlled osteotomy without subsequent repositioning in the same encounter, or where guidelines direct a separate Division code.

Commonly Confused With

RepositionThis family is frequently confused with Reposition (0PS), which also involves cutting bone but for the specific purpose of moving it to a new anatomic location, with Division reserved for cases where separation alone is the objective.
DrainageIt can also be confused with Drainage (0P9), which involves cutting into bone but specifically to release fluid or gas, a purpose Division explicitly excludes.
