About the I95–I99 Code Range
Low blood pressure, gangrene, and circulatory problems during or after procedures appear here. Gangrene means tissue death, usually from a loss of blood supply.
I95 divides low blood pressure by type, drug-related cause, association with hemodialysis, and other or unspecified forms. I96 identifies gangrene.
I97 separates problems during or after procedures by what happened, including heart-function disturbances, high blood pressure, bleeding, and accidental injury. I99 distinguishes other circulatory disorders from unspecified ones.
