Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Factors Influencing Duration

Age and response to medical or surgical treatment may influence length of disability. Additionally, many individuals with coronary artery occlusion suffer a stroke, which would significantly affect length of disability.

Medical Codes

ICD-9-CM:
433 - Occlusion and Stenosis of Precerebral Arteries
433.1 - Occlusion and Stenosis of Precerebral Arteries; Carotid Artery Occlusion
433.10 - Occlusion and Stenosis of Precerebral Arteries; Carotid Artery Occlusion; without Mention of Cerebral Infarction

Overview

Carotid artery occlusion is a narrow, partially obstructed area in one of the carotid arteries of the neck that prevents crucial blood flow to the brain. If blood flow to the brain continues to be blocked, transient ischemic attacks (TIAs), stroke, brain damage, and death can occur.

The occlusion is commonly caused by the deposit of fat cells within arterial walls (atherosclerosis), hardening and thickening of arterial walls (arteriosclerosis), or a tumor-like mass of plaque (atheroma). The blood clots (thrombi) that form as a result of these conditions can dislodge (emboli) and travel throughout the arteries in the body, causing potentially devastating consequences. Carotid artery occlusion can be compounded by the extension of cholesterol and calcium deposits into branches of the carotid arteries.

Other causes of carotid artery occlusion include inflammation of arteries (arteritis) or rheumatic heart disease. Thrombi and emboli from a bacterial infection of the heart (endocarditis), an irregular beat of the upper chamber (atrium) of the heart (atrial fibrillation) or from a heart attack (myocardial infarction) can also cause occlusion. Use of cocaine and amphetamines may possibly cause carotid artery occlusion.

Incidence and Prevalence: Symptomatic carotid artery occlusion occurs in about 6 in 100,000 persons in the US annually (Flaherty).
