Operation Definition
Pulling or stripping out or off all or a portion of a body part by the use of force
Procedure Overview
This family covers the forcible pulling or stripping of all or part of a peripheral nerve, most commonly seen in procedures like nerve stripping for certain chronic pain conditions or the mechanical avulsion of a nerve segment. It is a less common operation in this body system than in others, since peripheral nerves are usually cut or dissected free rather than pulled out under force.
When it is performed, the intent is typically to eliminate a nerve's function entirely by physically removing it through traction rather than sharp dissection, often for a nerve that is already damaged beyond repair or is the source of persistent, difficult-to-treat pain.
Anatomy & Axis Detail
Ulnar Nerve
The ulnar nerve travels along the medial arm, behind the medial epicondyle at the elbow, and into the forearm and hand, where it governs intrinsic hand muscles and sensation over the little finger. Extraction of this nerve involves physically removing foreign material, such as a retained needle fragment, wire, or bone chip, that has become lodged along its course, commonly following trauma or a prior surgical procedure in the region. The nerve's superficial and exposed position at the cubital tunnel makes it particularly vulnerable to penetrating injury and subsequent embedded debris, and retrieval there demands care to avoid worsening ulnar neuropathy symptoms like hand weakness or numbness. Precise documentation of the forearm or elbow location helps distinguish this from a more proximal brachial plexus procedure.
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
This code is used only when the documentation specifically describes force, such as pulling or stripping, being used to remove the nerve or a portion of it, rather than a scalpel or cautery cutting it free. Because this method is uncommon for peripheral nerves, coders should read the operative note carefully to confirm the technique actually matches Extraction and was not simply described loosely by the surgeon when a standard excision was performed. Vein stripping terminology from vascular procedures is sometimes mistakenly carried over to nerve cases, leading to incorrect code selection when the actual technique was sharp dissection.
