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.

Comorbid Conditions

Factors Influencing Duration

Factors include the individual's age, lifestyle modifications, the extent of renovascular damage and systemic vascular disease, presence of bilateral disease, the specific treatments instituted (medical or surgical), the individual's response to treatment, and the development of complications.

Medical Codes

ICD-9-CM:
405 - Hypertension, Secondary
405.0 - Hypertension, Secondary, Malignant
405.01 - Renovascular Hypertension, Secondary, Malignant
405.09 - Hypertension, Secondary, Malignant, Other
405.1 - Hypertension, Secondary, Benign
405.11 - Renovascular Hypertension, Secondary, Benign
405.19 - Hypertension, Secondary, Benign, Other
405.9 - Hypertension, Secondary, Unspecified
405.91 - Hypertension, Renovascular, Secondary, Unspecified
405.99 - Hypertension, Secondary, Unspecified, Other

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 elevated cholesterol in the blood (hyperlipidemia), severe high blood pressure (malignant hypertension), fibromuscular disease, and/or diabetes mellitus? Is there a family history of any of these disorders or of renovascular hypertension?
  • Does individual smoke cigarettes?
  • Does individual complain of headache, anxiety, heart irregularity or pounding (palpitations), a rapid heartbeat (tachycardia), light-headedness, and mental sluggishness?
  • Has blood pressure been controlled with properly taken medication? Has individual's controlled high blood pressure suddenly elevated?
  • Were blood tests done such as blood urea nitrogen (BUN), creatinine, potassium, and plasma renin activity? Was the captopril test done followed by measurement of renin in the blood? Did renin elevate, suggesting renovascular hypertension? Is it fairly certain that these results were not false-positive results, particularly if individual is black?
  • Was radioisotope renography or captopril renography done? Were ultrasound, magnetic resonance angiography (MRA), or CT required? Was renal arteriography performed if individual was deemed at high-risk for renovascular hypertension?
  • Was the diagnosis of renovascular hypertension confirmed?

Regarding treatment:

  • Did treatment require surgical revascularization or angioplasty with stent placement?
  • Did any complications develop after surgery?
  • If individual has atherosclerosis or is a poor candidate for revascularization or angioplasty, were angiotensin-converting enzyme (ACE) inhibitors and calcium channel blockers used? Is the medication improving the renovascular hypertension?
  • Are underlying disorders such as diabetes, hypertension, and increased cholesterol responding to treatment? Is individual compliant with all medication and treatment regimens as prescribed?

Regarding prognosis:

  • Does the condition affect one (unilateral) or both (bilateral) renal arteries?
  • Is this the initial diagnosis or have the arteries become obstructed again (restenosed)?
  • If surgery or angioplasty was done, did any complications arise after the procedure?
  • If individual is taking an angiotensin-converting enzyme (ACE) inhibitor, has this caused a decline in kidney function?
  • Does individual diligently comply with all medication and treatment regimens?
  • Have any complications developed such as congestive heart failure, heart attack (myocardial infarction), cerebrovascular accident (stroke), pulmonary edema, or renal failure? If so, what are they and what is expected outcome with treatment?
