I70.244 Atherosclerosis of native arteries of left leg with ulceration of heel and midfoot

Name of the Condition

• Common Name: Peripheral Artery Disease (PAD) with heel and midfoot ulceration
• Medical Term: Atherosclerosis of native arteries of left leg with ulceration of heel and midfoot
• ICD-10 Code: I70.244

Summary

Atherosclerosis of native arteries of left leg with ulceration of heel and midfoot is a condition where plaque buildup narrows the arteries supplying blood to the left leg, leading to reduced blood flow and the development of open sores (ulcers) specifically on the heel and midfoot. This is a specific form of peripheral artery disease (PAD) that can cause tissue damage and may progress to severe complications if untreated.

Causes

Atherosclerosis develops due to damage to the arterial lining, often triggered by factors like high cholesterol, high blood pressure, or inflammation. Over time, plaque accumulates at the site of injury, thickening and hardening the artery walls, which restricts blood flow to the left leg. The reduced blood flow impairs oxygen and nutrient delivery to tissues, leading to ulcer formation and potential tissue death.

Risk Factors

• Age (more common in older adults)
• Family history of cardiovascular disease
• High cholesterol or triglyceride levels
• Hypertension (high blood pressure)
• Smoking or tobacco use
• Diabetes or insulin resistance
• Obesity or sedentary lifestyle
• Unhealthy diet (high in saturated fats, trans fats, or sodium)

Symptoms

• Open sores or ulcers on the heel and midfoot of the left leg
• Persistent pain or cramping in the left leg, especially during activity
• Reduced sensation or numbness in the affected area
• Changes in skin color (pale, bluish, or darkened)
• Slow-healing wounds
• Weak or absent pulses in the left leg

Diagnosis

Diagnosis involves a physical examination to assess ulceration and blood flow, along with non-invasive tests like ankle-brachial index (ABI) to measure blood pressure in the legs. Imaging studies, such as Doppler ultrasound or angiography, may be used to visualize arterial narrowing. Blood tests to check cholesterol, glucose, and inflammatory markers may also be performed to identify underlying causes.

Treatment Options

Treatment focuses on improving blood flow and promoting ulcer healing. This may include lifestyle modifications (e.g., smoking cessation, exercise), medications (e.g., antiplatelet agents, cholesterol-lowering drugs), and wound care. In severe cases, revascularization procedures like angioplasty or bypass surgery may be necessary to restore blood flow.

Prognosis and Follow-Up

Prognosis depends on the severity of arterial disease and response to treatment. Regular follow-up is essential to monitor ulcer healing, manage risk factors, and prevent complications. Early intervention improves outcomes, but advanced cases may require ongoing care to avoid amputation or further tissue damage.

Complications

• Non-healing ulcers or infection
• Tissue death (gangrene)
• Amputation of the affected limb
• Increased risk of heart attack or stroke
• Chronic pain or disability

Lifestyle & Prevention

• Maintain a healthy diet low in saturated fats and sodium
• Engage in regular physical activity
• Quit smoking or avoid tobacco use
• Manage blood pressure, cholesterol, and blood sugar levels
• Inspect feet daily for sores or changes
• Wear proper footwear to reduce pressure on the heel and midfoot

When to Seek Professional Help

Seek medical attention if you notice new or worsening ulcers, persistent pain, or signs of infection (e.g., redness, swelling, pus) on the heel or midfoot. Prompt care is critical to prevent complications and improve healing.

Tips for Medical Coders

Document the location (heel and midfoot) and laterality (left leg) clearly in the medical record. Ensure the ulceration is linked to atherosclerosis of native arteries, not grafts or other vessel types. Verify that the code I70.244 is used only when the ulceration is specifically on the heel and midfoot of the left leg.
