Completely closing an orifice or the lumen of a tubular body part
Procedure Overview
Occlusion procedures in this body system close off a duct, vessel, or opening within the liver, gallbladder, bile ducts, or pancreas so that fluid can no longer pass through it. This is most often performed on a bile duct or pancreatic duct that is leaking, diseased, or being deliberately sealed to redirect flow elsewhere, and less commonly on a blood vessel supplying these organs to stop bleeding or cut off circulation to a tumor.
Clinicians use this approach when a duct has been injured, is fistulizing to another structure, or needs to be sacrificed as part of a larger surgical plan, such as closing a stump left after partial removal of an organ. It may also be used to block blood flow into a tumor before resection, reducing bleeding risk during the main procedure.
The underlying idea is that the tubular structure remains anatomically in place but its lumen is deliberately shut, using clips, ligatures, embolic material, or a similar technique, rather than being cut out or repaired to restore normal function.
Anatomy & Axis Detail
Hepatic Duct, Common
The common hepatic duct forms from the union of the right and left hepatic ducts and carries the entire bile output of the liver before it joins the cystic duct to become the common bile duct, making it a critical conduit whose occlusion has consequences for the whole organ rather than an isolated segment. Deliberate closure of this duct is uncommon and is generally limited to specific reconstructive or oncologic scenarios where bile flow is being redirected through an alternate route, such as a biliary-enteric bypass, rather than left to drain through the native pathway. Given the duct's central position near the hepatic artery and portal vein, any procedure occluding it warrants careful review of the accompanying vascular and reconstructive steps documented in the operative note.
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
Coders should look for explicit documentation that a duct or vessel was ligated, clipped, coiled, embolized, or otherwise closed off completely, and confirm which specific structure and approach was used, since embolization performed percutaneously through interventional radiology is coded differently in device and approach values than a duct tied off during open surgery. The device value must reflect whether an extraluminal device such as a clip or ligature, or an intraluminal device such as a coil, was left in place.
A frequent error is confusing partial narrowing or compression of a duct with true occlusion, when the intent and result must be complete closure of the lumen. Another common mistake is coding Occlusion when the vessel or duct was actually cut and its ends tied off as an incidental part of a different procedure, such as division during a resection, in which case the occlusion is not coded separately.
