Chapter 9
Diseases of the circulatory system
I00-I99
This chapter covers the circulatory system, including hypertension, ischemic heart disease, heart failure, and cerebrovascular disease. ICD-10-CM presumes a causal link between hypertension and certain heart or kidney conditions when both are documented, which changes how these conditions are coded together.
