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 cut into a peripheral nerve to sever or transect it, separating the nerve without draining any fluid, in order to interrupt the signals it carries. A common example is sectioning a nerve to relieve severe, treatment-resistant pain or to correct an abnormal muscle contraction pattern that the nerve is driving.

Surgeons turn to this approach when a nerve is identified as the direct source of a disabling symptom, such as a facial nerve branch causing spasm, or a sensory nerve implicated in chronic localized pain, and less invasive measures have not worked. Because division is generally permanent and the nerve typically will not meaningfully regenerate its original function, it is considered a more definitive step than nerve blocks or ablation.

The procedure is usually done with precise surgical dissection to isolate the specific nerve or nerve branch before it is cut, minimizing collateral effect on adjacent structures.

Anatomy & Axis Detail

Cervical Plexus

The cervical plexus is a network formed by the ventral rami of C1-C4 lying deep to the sternocleidomastoid muscle, supplying sensory branches to the neck, scalp, and shoulder skin along with motor fibers including contributions to the phrenic nerve. Division of the cervical plexus interrupts these conduction pathways without excising tissue, and is performed for conditions such as spasmodic torticollis or intractable neck and shoulder pain where selective transection of specific branches can relieve symptoms while sparing others. Because the plexus lies near the carotid sheath and deep cervical fascia, the surgeon must identify and isolate the individual rootlets or branches targeted, and documentation should specify which components were divided given the plexus's role in both sensation and diaphragmatic innervation.

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

To assign a code from this family, documentation must show the nerve was cut through with the specific intent of separating or transecting it, not simply exposed or manipulated during a broader procedure. The operative note should identify the exact nerve and confirm no fluid or gas was drained as part of the same act, since that would point toward a different root operation.

A common coding slip is selecting Division when the surgeon actually destroyed the nerve with an ablative agent or energy source rather than physically cutting it, which belongs under Destruction instead. Coders also sometimes miss that if the transected nerve segment is also removed from the body, the procedure may need to be coded as Excision rather than, or in addition to, Division.

Commonly Confused With

DestructionDivision is frequently confused with Destruction, since both interrupt nerve function, but Division is a mechanical cut while Destruction uses energy, cold, or a chemical agent without cutting.
ReleaseIt is also distinguished from Release, which frees a nerve from surrounding scar tissue or adhesions to relieve compression without cutting the nerve itself.
