Endovascular Occlusion of Vessel

Effective October 1, 2011, code 39.77, Temporary (partial) therapeutic endovascular occlusion of vessel, was created to classify procedures in which the vessel is partially occluded via an endovascular device. Currently, the procedure has been approved for an endovascular balloon catheter to partially occlude the abdominal aorta to treat patients with cerebral ischemia. Prior to this change, there was no unique or predecessor code to describe this procedure. This procedure is different from existing occlusion procedure codes which completely occlude the vessel or permanently occlude the vessel. Code 39.78, Endovascular implantation of branching or fenestrated graft(s) in aorta...

Article Overview

This article covers updates to ICD-9-CM procedure coding for endovascular vessel procedures, with emphasis on newly created codes, revised code titles, and inclusion/exclusion terms. It is relevant to coding professionals working with vascular, interventional, and aneurysm-related procedures, especially those involving aorta and head and neck vessel services. The article also summarizes related guidance tied to effective dates and code-family revisions.

Why This Topic Matters

These coding updates affect how endovascular vascular procedures are categorized and reported, particularly when new technology or distinct procedural approaches are involved. Understanding the scope of the code-family revisions helps reduce misclassification and supports accurate procedural coding.

Article Sections

  1. Code family revisions and new endovascular procedure codes

    This section outlines changes to the endovascular procedures on vessel(s) code family, including revised titles and newly added procedural categories. It also notes related inclusion and exclusion terms within the code set.

  2. Background on temporary partial occlusion and branching or fenestrated graft technology

    This section provides general background on the new endovascular procedure categories and the clinical context for the technology discussed. It describes the broad procedural focus without detailing coding rules.

  3. Code listings and revision notes

    This section presents the specific code updates, including newly created codes, revised code titles, and related cross-references. It also identifies associated exclusions and linked diagnostic or procedural references.
