Chapter 11: Diseases of the Circulatory System
ICD-11 to ICD-10 crosswalk mappings for codes BA00-BE2Z
176 ICD-11 codes in this chapter have ICD-10 crosswalk mappings from the WHO.
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.
