Atherosclerosis of native arteries of extremities with intermittent claudication
ICD-10 I70.21 is a used to indicate a diagnosis of atherosclerosis of native arteries of extremities with intermittent claudication.
I70.21 refers to atherosclerosis of the native arteries of the extremities with intermittent claudication. This condition is characterized by the narrowing of arteries due to plaque buildup, leading to reduced blood flow, particularly during physical activities. Clinically, patients may experience symptoms such as leg pain or cramping during exercise, which typically resolves with rest. The anatomy involved includes the femoral, popliteal, and tibial arteries, which supply blood to the lower limbs. Disease progression can lead to more severe complications, including critical limb ischemia or even limb loss if untreated. Diagnosis often involves a thorough clinical evaluation, including a detailed patient history, physical examination, and diagnostic tests such as Doppler ultrasound or angiography to assess blood flow and identify the extent of arterial blockage. Early detection and management are crucial to prevent further complications and improve patient outcomes.

I70.21 specifically covers atherosclerosis of the native arteries of the extremities that leads to intermittent claudication, characterized by pain or cramping in the legs during physical activity due to inadequate blood flow.
I70.21 should be used when the patient presents with intermittent claudication due to atherosclerosis of the native arteries. It is important to differentiate this from I70.20, which does not include claudication.
Documentation should include a detailed patient history, evidence of intermittent claudication symptoms, results from diagnostic tests such as ABI (Ankle-Brachial Index), and any treatment plans or interventions undertaken.
