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.

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.

Medical Codes

ICD-9-CM:
701.4 - Keloid Scar; Cheloid; Hypertrophic Scar

Overview

A keloid is a raised, hard, thick, itchy scar on the skin secondary to abnormal proliferation of connective tissue.

A keloid occurs when the scar tissue response is out of proportion to the amount needed for normal repair and healing. Because of a defective healing process, excess collagen forms at the site of a healing injury or surgical incision. Keloids may continue to enlarge over time and become unsightly. Most eventually flatten out and stop itching.

Although keloids can occur anywhere on the body, the most common sites are the chest, upper back, and shoulder muscle (deltoid) areas. Keloids can also develop at the site of acne pustules. Although they generally occur secondary to a wound, keloids may arise spontaneously. There is a genetic tendency to form keloids; dominant and recessive inheritance patterns have been described. Keloids must be differentiated from a related condition called "hypertrophic scar." While a hypertrophic scar is a thick scar that remains within the borders of a wound, the keloid extends over the skin beyond the original wound borders in a claw-like growth pattern; however, it almost never extends into subcutaneous tissue. In the past, keloids and hypertrophic scars were considered as a part of a spectrum. Now there is a tendency to consider them as separate entities.
