Other and unspecified disorders of the circulatory system (I95-I99)
ICD-10 codes I95-I99 cover a variety of other and unspecified disorders of the circulatory system, including different types of hypotension, gangrene, and complications related to circulatory system procedures. These codes are essential for categorizing conditions not classified elsewhere in the circulatory system chapter.
Specifically, I95 focuses on types of hypotension such as idiopathic hypotension, orthostatic hypotension, drug-induced hypotension, and postprocedural hypotension. Codes like I96 address gangrene not classified elsewhere, encompassing peripheral vascular gangrene and skin necrosis. The I97 series details intraoperative and postprocedural complications of the circulatory system, including postcardiotomy syndrome, cardiac functional disturbances, hemorrhage, lacerations, and postprocedural hypertension. This section also describes various cardiac arrests and heart failures linked to surgery or medical procedures. Finally, I99 captures other and unspecified circulatory disorders such as ischemia of limbs, vascular calcification, and hereditary cardiovascular conditions. These codes help coders and clinicians document complex circulatory conditions and procedural complications accurately, supporting precise diagnosis and treatment tracking.
