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. 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.

Factors Influencing Duration

Factors that influence the length of disability include continued alcohol consumption, the development of associated complications, compliance with treatment, the age and general health of the individual, and the severity of the disease or condition upon initial diagnosis.

Medical Codes

ICD-9-CM:
573.0 - Liver Congestion, Passive, Chronic
573.2 - Hepatitis in Other Infectious Diseases Classified Elsewhere
573.3 - Hepatitis, Unspecified; Toxic (Noninfectious) Hepatitis
573.4 - Hepatic Infarction

Failure to Recover

If an individual fails to recover within the expected maximum duration period, the reader may wish to consider the following questions to better understand the specifics of an individual's medical case.

Regarding diagnosis:

  • Does individual have a history of chronic exposure to alcohol and/or drugs? Occupational or environmental contact with toxic substances?
  • Has individual received a recent blood transfusion?
  • Has individual had a recent tattoo applied?
  • Is there a history of viral infection, particularly of hepatitis A, B, C, D, or E? Does individual have a history of infections, metabolic disorders, or cancer that can affect the liver directly?
  • Does individual report abdominal pain, yellowing of the skin (jaundice), fatigue, weakness, and/or fever and chills?
  • Is there weight loss, dark urine, itching, or loss of appetite?
  • Were blood tests done to measure liver enzymes (alkaline phosphatase, AST, ALT, GGT, LDH) and proteins (bilirubin, albumin, fibrinogen)?
  • Were tests for viral hepatitis performed?
  • Were immunoglobulin levels, ammonia, clotting factors, and blood lipids measured? Was MRI, ultrasound, or CT required? Was a tissue sample (biopsy) of the liver taken to identify inflammation, cirrhosis, and infection?
  • Was a diagnosis of liver disease confirmed?

Regarding treatment:

  • What type of liver disease does individual have, and what is the underlying cause? How is the underlying cause being treated?
  • Did general treatment include dietary and vitamin supplementation and the administration of anti-inflammatory drugs?
  • Does individual understand the importance of avoidance of alcohol and chemicals that are toxic to the liver?
  • Would individual benefit from chemical dependency counseling?
  • If abscesses and infection were present, were organism-specific antibiotics given?
  • Was individual compliant with the medication regimen?
  • Was surgical removal (resection) of a tumor required? If so, was the tumor removed completely?

Regarding prognosis:

  • What type of liver disease does individual have?
  • How severely was the liver damaged?
  • Is the underlying cause under control? If not, what other treatment options are available?
  • Has individual developed complications of liver disease such as infection, fluid retention in the abdomen (ascites), blood flow impairment through the portal vein that serves the liver (portal hypertension), liver failure, bleeding, inflammation of the pancreas (pancreatitis), or neurological damage (hepatic encephalopathy)?
  • How will the complications be treated, and what is the expected outcome with treatment?
