Types of Endoleaks Following Endovascular Aneurysm Repair
Endoleaks are not uncommon and can occur when blood leaks back into an aneurysmal sac, resulting in pressure within the sac following endovascular aneurysm repair (EVAR) procedures. The common endpoint is a buildup of pressure outside of the graft, but within the aneurysmal sac, as opposed to a true leak where blood leaks out of the circulatory system altogether. The types of endoleaks differ in the point of origin of the leak. The following descriptions are being provided in response to many requests for assistance in reporting the appropriate codes for both diagnoses and procedures. The descriptions below are...

Article Overview
This educational article reviews the broad types of endoleaks that can occur after endovascular aneurysm repair (EVAR) and frames them in the context of ICD-10-CM diagnosis assignment and related procedure coding considerations. It is intended for coders and other healthcare professionals who need a high-level understanding of post-EVAR complications, terminology, and how the article approaches reporting guidance for common endoleak scenarios.
Why This Topic Matters
Post-EVAR endoleaks are clinically important because they can affect follow-up care, complication tracking, and how records are coded for diagnosis and procedure reporting. Understanding the article’s scope helps coding and documentation staff identify whether it addresses the endoleak types, terminology, and coding classification questions relevant to their cases.
Article Sections
-
Overview of endoleaks after EVAR
Introduces endoleaks in the setting of endovascular aneurysm repair and explains the general concept of blood re-entering the aneurysmal sac after repair. It also notes that the article is intended to support coding-oriented review.
-
Type I endoleak
Summarizes the subcategories and general clinical characteristics of Type I endoleaks. The section also discusses the article’s ICD-10-CM assignment approach for this category.
-
Type II endoleak
Reviews the Type II endoleak category, including its broad subtypes and general mechanism. The section also addresses how the article classifies this type for diagnosis coding.
-
Type III endoleak
Covers the Type III endoleak category and its broad subtypes in relation to endograft integrity and component separation. It also discusses the article’s coding classification for this type.
-
Type IV endoleak
Describes the Type IV endoleak category and its general relationship to graft leakage and early postoperative complications. The section includes the article’s diagnosis coding assignment for this type.
-
Type V endoleak
Explains the Type V endoleak category and its general presentation when no discrete leak is identified. The section also notes the article’s coding classification for this type.
-
Clinical scenario and coding question
Presents a postoperative case involving endoleak findings and a subsequent repair scenario. The section asks how the diagnosis and procedure should be coded.
