Version 2023
ICD-10:I70.33
Short Description:Athscl unsp type bypass of the right leg w ulceration
Long Description:Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the circulatory system (I00–I99)
    • Diseases of arteries, arterioles and capillaries (I70-I79)
      • Atherosclerosis (I70)

I70.33 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like I70.33 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding for Athscl unsp type bypass of the right leg w ulceration

Non-specific codes like I70.33 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for athscl unsp type bypass of the right leg w ulceration:

  • BILLABLE CODE - Use I70.331 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of thigh
  • BILLABLE CODE - Use I70.332 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of calf
  • BILLABLE CODE - Use I70.333 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of ankle
  • BILLABLE CODE - Use I70.334 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of heel and midfoot
  • BILLABLE CODE - Use I70.335 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of other part of foot
  • BILLABLE CODE - Use I70.338 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of other part of lower leg
  • BILLABLE CODE - Use I70.339 for Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of unspecified site

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Atherosclerosis

Atherosclerosis is a disease in which plaque builds up inside your arteries. Plaque is a sticky substance made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. That limits the flow of oxygen-rich blood to your body.

Atherosclerosis can lead to serious problems, including:

Atherosclerosis usually doesn't cause symptoms until it severely narrows or totally blocks an artery. Many people don't know they have it until they have a medical emergency.

A physical exam, imaging, and other diagnostic tests can tell if you have it. Medicines can slow the progress of plaque buildup. Your doctor may also recommend procedures such as angioplasty to open the arteries, or surgery on the coronary or carotid arteries. Lifestyle changes can also help. These include following a healthy diet, getting regular exercise, maintaining a healthy weight, quitting smoking, and managing stress.

Peripheral Arterial Disease

Peripheral arterial disease (PAD) happens when there is a narrowing of the blood vessels outside of your heart. The cause of PAD is atherosclerosis. This happens when plaque builds up on the walls of the arteries that supply blood to the arms and legs. Plaque is a substance made up of fat and cholesterol. It causes the arteries to narrow or become blocked. This can reduce or stop blood flow, usually to the legs. If severe enough, blocked blood flow can cause tissue death and can sometimes lead to amputation of the foot or leg.

The main risk factor for PAD is smoking. Other risk factors include older age and diseases like diabetes, high blood cholesterol, high blood pressure, heart disease, and stroke.

Many people who have PAD don't have any symptoms. If you have symptoms, they may include:

PAD can increase your risk of heart attack, stroke, and transient ischemic attack.

Doctors diagnose PAD with a physical exam and heart and imaging tests. Treatments include lifestyle changes, medicines, and sometimes surgery. Lifestyle changes include dietary changes, exercise, and efforts to lower high cholesterol levels and high blood pressure.
