Frequently Asked Questions
What ICD-11 codes are in Chapter 11?
Chapter 11: Diseases of the Circulatory System covers ICD-11 codes BA00-BE2Z. It contains 24 code blocks with 158 top-level categories.
What conditions does ICD-11 Chapter 11 cover?
One of the most heavily coded chapters, covering hypertension, heart failure, coronary artery disease, atrial fibrillation, stroke, deep vein thrombosis, and peripheral vascular disease. ICD-11 improves classification of heart failure subtypes and cerebrovascular conditions. This chapter includes codes from BA00-BE2Z.
How is ICD-11 Chapter 11 different from ICD-10?
ICD-11 reorganized many chapters compared to ICD-10. Chapter 11 (Diseases of the Circulatory System) may include conditions that were in different ICD-10 chapters, and some conditions previously here may have moved. ICD-11 also adds new chapters for sleep-wake disorders, sexual health, and traditional medicine that did not exist in ICD-10.
How many code blocks are in ICD-11 Chapter 11?
Chapter 11 has 24 code blocks: BA00-BA04 (Hypertensive diseases), BA20-BA2Z (Hypotension), BA40-BA4Z (Acute ischaemic heart disease), BA40-BA6Z (Ischaemic heart diseases), and 20 more.
