E13.5: Other specified diabetes mellitus with peripheral circulatory complications

E13.5, or "Other specified diabetes mellitus with peripheral circulatory complications," describes a specific form of diabetes that results in problems with blood flow to the extremities, typically the legs and feet. Diabetes is a chronic health condition where the body does not produce or properly use insulin, which results in high levels of sugar in the blood. This form of diabetes is distinct because it leads to circulatory complications, specifically in the peripheral areas of the body. These circulatory issues commonly present as numbness, tingling, pain, or a cold feeling in the legs or feet, and can lead to slow wound healing. Over time, untreated peripheral circulatory complications can progress, and in severe cases, may necessitate amputation of the affected limb for the patient's survival.
