Procedure Overview

Occlusion procedures in the eye close off a natural or acquired opening so that nothing can pass through it. In ophthalmology, the most familiar example is closing a lacrimal punctum or canaliculus, the small drainage openings at the inner corner of the eyelid, to treat chronic dry eye. By blocking tear drainage, more of the eye's natural tears stay on the ocular surface longer, easing irritation for patients whose dryness hasn't responded to drops alone.

This family also covers occluding other tubular or open structures within the eye when a surgeon needs to permanently seal a pathway, such as closing an abnormal opening created by prior trauma or disease. The technique can involve a temporary plug, a permanent implantable device, or the use of heat or chemical cautery to seal tissue shut.

Because the effect is meant to be lasting, patients considering punctal occlusion often try a reversible plug first before agreeing to a permanent, cautery-based closure. Recovery is typically minimal, though some people notice mild watering or irritation as the eye adjusts to reduced tear drainage.

Anatomy & Axis Detail

Lacrimal Duct, Left

The left lacrimal duct drains tears from the eye toward the nasal cavity, and occluding it is a deliberate measure to reduce tear drainage in patients with significant dry eye symptoms who have not responded to lubricating drops alone. The procedure usually involves inserting a small plug into the punctum or canaliculus, though thermal or surgical closure of the duct is another option when a more lasting block is desired. Because the left lacrimal drainage system runs from the eyelid margin through a narrow canaliculus into the nasolacrimal sac, the exact point of occlusion determines how much residual drainage capacity remains. This code captures the closure itself, and coders should note the device type and whether the occlusion is intended to be temporary or permanent, since that shapes both patient counseling and follow-up.

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.

Device: Intraluminal Device

Intraluminal Device denotes a single device, such as a stent or occlusion device, positioned within the lumen of a tubular body part like a vessel, duct, or airway to maintain patency or occlude flow. It carries no drug coating or radioactivity, distinguishing it from the drug-eluting, radioactive, and bioactive intraluminal device values, and from Extraluminal Device, which sits outside rather than inside the lumen.

Coding & Documentation

The documentation needs to clearly state that an opening was closed off entirely, not just narrowed or partially obstructed, and coders must identify whether the device used to achieve occlusion is temporary (like a dissolvable or removable plug) or intended to stay permanently. That distinction affects the device value appended to the code, and missing it is one of the most frequent errors in this family.

Coders also need to watch for the method: cautery-based punctal occlusion has no device value since nothing is left behind, while plug placement does. Confusing a punctal plug procedure, which closes a drainage duct, with a device coded under a different root operation because the surgeon used adhesive rather than a mechanical device is another common slip - the material used still counts as an occlusion if the goal was blocking flow, not repairing structure.

Commonly Confused With

RestrictionOcclusion is easily confused with Restriction, which only partially narrows a lumen rather than closing it completely; if any flow is still possible through the opening, Restriction is the correct root operation instead.
RepairIt also differs from Repair, since Repair addresses damaged or malfunctioning anatomy rather than deliberately sealing a functioning passage.
RemovalWhen a device like a punctal plug is later taken out, that reversal is coded as Removal, not as a new Occlusion procedure.
