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, Right

The right humeral shaft is the long diaphyseal segment between the surgical neck and the supracondylar region, and dividing it is the surgical basis for corrective osteotomy of angular or rotational deformity after a poorly healed fracture. Surgeons also cut the shaft to shorten or derotate the arm in cases of limb-length discrepancy or congenital malalignment, or as a controlled step in limb-lengthening constructs where the cut is later distracted. The shaft's thick cortical bone requires a saw or drill-and-osteotome technique, and the radial nerve spiraling along its posterior surface in the mid-shaft region is a key structure to protect. The chosen cut geometry, transverse, oblique, or step-cut, directly influences rotational and axial stability once fixation is applied.

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.
