What ICD-10 codes are used for peripheral artery disease (PAD)?

Peripheral artery disease (PAD), a.k.a. peripheral vascular disease, is a circulatory condition that affects blood flow to the limbs, often causing pain and numbness. Here are ten commonly used ICD-10-CM codes for PAD, along with brief clinical descriptions:

I70.211 - Atherosclerosis of native arteries of extremities with intermittent claudication, right leg: Used when there is atherosclerosis (narrowing of arteries due to plaque buildup) in the native arteries of the right leg, causing intermittent claudication (pain or cramping during physical activity).

I70.212 - Atherosclerosis of native arteries of extremities with intermittent claudication, left leg: Applied for atherosclerosis in the native arteries of the left leg, resulting in intermittent claudication.

I70.213 - Atherosclerosis of native arteries of extremities with intermittent claudication, bilateral legs: Utilized when atherosclerosis affects the native arteries of both legs, causing intermittent claudication.

I70.221 - Atherosclerosis of native arteries of extremities with rest pain, right leg: Used when atherosclerosis in the native arteries of the right leg leads to rest pain (pain at rest).

I70.222 - Atherosclerosis of native arteries of extremities with rest pain, left leg: Applied for atherosclerosis in the native arteries of the left leg, resulting in rest pain.

I70.223 - Atherosclerosis of native arteries of extremities with rest pain, bilateral legs: Utilized when atherosclerosis affects the native arteries of both legs, causing rest pain.

I70.231 - Atherosclerosis of native arteries of right leg with ulceration of thigh: Used when atherosclerosis in the native arteries of the right leg results in ulceration (open sores).

I70.232 - Atherosclerosis of native arteries of right leg with ulceration of calf: Applied for atherosclerosis in the native arteries of the left leg, leading to ulceration.

I70.233 - Atherosclerosis of native arteries of right leg with ulceration of ankle: Utilized when atherosclerosis affects the native arteries of both legs, causing ulceration.

I70.238 - Atherosclerosis of native arteries of right leg with ulceration of other part of lower leg: Used for atherosclerosis in the native arteries of the extremities (arms or legs) with ulceration.

Which PAD ICD codes are billable?

The billable status of the mentioned ICD-10 codes for Peripheral Artery Disease (PAD) varies:

I70.211 - Atherosclerosis of native arteries of right leg with intermittent claudication: Yes, billable. Medical expenses related to PAD with intermittent claudication in the right leg can be claimed.

I70.212 - Atherosclerosis of native arteries of left leg with intermittent claudication: Yes, billable. Costs associated with PAD with intermittent claudication in the left leg can be reimbursed.

I70.213 - Atherosclerosis of native arteries of bilateral legs with intermittent claudication: Yes, billable. Medical expenses for PAD with intermittent claudication in both legs can be claimed.

I70.221 - Atherosclerosis of native arteries of right leg with rest pain: Yes, billable. Expenses related to PAD with rest pain in the right leg can be reimbursed.

I70.222 - Atherosclerosis of native arteries of left leg with rest pain: Yes, billable. Medical expenses for PAD with rest pain in the left leg can be claimed.

I70.223 - Atherosclerosis of native arteries of bilateral legs with rest pain: Yes, billable. Costs associated with PAD with rest pain in both legs can be reimbursed.

I70.231 - Atherosclerosis of native arteries of right leg with ulceration: Yes, billable. Medical expenses for PAD with ulceration in the right leg can be claimed.

I70.232 - Atherosclerosis of native arteries of left leg with ulceration: Yes, billable. Expenses related to PAD with ulceration in the left leg can be reimbursed.

I70.233 - Atherosclerosis of native arteries of bilateral legs with ulceration: Yes, billable. Medical expenses for PAD with ulceration in both legs can be claimed.

I70.238 - Atherosclerosis of native arteries of extremities with ulceration: Yes, billable. Costs associated with PAD with ulceration in the extremities can be reimbursed.

Clinical information

  • Peripheral artery disease (PAD) is a vascular condition (a circulatory system problem) characterized by the narrowing or blockage of arteries outside the heart, typically in the legs.
  • Common risk factors for PAD include smoking, diabetes, hypertension, high cholesterol, and a history of cardiovascular disease.
  • Symptoms of PAD may include intermittent claudication (leg pain while walking), numbness, weakness, or coldness in the affected limb.
  • It can be caused by atherosclerosis.
  • Diagnosis involves a thorough medical history, physical examination, and non-invasive tests like ankle-brachial index (ABI) measurement or Doppler ultrasound.
  • In some cases, more detailed imaging may require angiography or CT angiography.
  • Management includes lifestyle modifications (smoking cessation, exercise, diet), medication to control risk factors, and antiplatelet therapy (e.g., aspirin).
  • Revascularization procedures like angioplasty with stent placement or bypass surgery may be necessary for severe PAD cases.
  • Healthcare practitioners should educate patients on the importance of PAD management to prevent complications like limb amputation and cardiovascular events.
  • Regular follow-up and monitoring are crucial to assess treatment effectiveness, symptom improvement, and disease progression.
  • Collaborative care involving vascular specialists, cardiologists, and primary care providers is often required for comprehensive PAD management.
  • Please do note mistake this for posterior cerebral artery stroke or carotid artery disease.

Commonly asked questions

Yes, lifestyle changes can help prevent or manage PAD. These include quitting smoking, managing diabetes, controlling blood pressure and cholesterol levels, regular exercise, and maintaining a healthy diet.

Risk factors for PAD include smoking, diabetes, high blood pressure, high cholesterol, obesity, family history of vascular disease, and age, especially over 50.

Diagnosis may involve physical exams, imaging tests (like Doppler ultrasound), and ankle-brachial index (ABI) measurements. Treatment may include lifestyle changes, medications, angioplasty, stenting, or surgery, depending on the severity of the condition. Early diagnosis and management are crucial to prevent complications.
