Back Condition (Lumbar/Thoracolumbar Spine)

Back conditions commonly cause secondary conditions, especially neurological symptoms in the lower extremities.

5 known secondary conditions

Secondary Conditions

The following conditions may be claimed as secondary to Back Condition (Lumbar/Thoracolumbar Spine):

Radiculopathy (Lower Extremity)

DC: 8520/8521 Max Rating: 80% per extremity
Caused By Established Link

Medical Connection

Disc herniation, stenosis, or other spine pathology can compress nerve roots, causing radiating pain, numbness, and weakness in the legs.

Evidence Tips

  • EMG/nerve conduction study
  • MRI showing nerve compression
  • Neurological examination documenting sensory/motor deficits
  • Each leg is rated separately

Depression

DC: 9434 Max Rating: 100%
Caused By Established Link

Medical Connection

Chronic pain from back conditions frequently leads to depression due to loss of function, sleep disruption, and reduced quality of life.

Evidence Tips

  • Mental health evaluation
  • Documentation of chronic pain
  • Research on chronic pain and depression

Bowel/Bladder Dysfunction

DC: 7332/7517 Max Rating: 100%
Caused By Established Link

Medical Connection

Severe spine conditions can affect nerve pathways controlling bowel and bladder function.

Evidence Tips

  • Urological evaluation
  • Documentation of cauda equina symptoms
  • MRI showing significant nerve compression

Knee Condition (Secondary)

DC: 5260/5261 Max Rating: 60%
Caused By Strong Evidence

Medical Connection

Altered gait from back pain causes uneven weight distribution and stress on the knees, leading to degenerative changes.

Evidence Tips

  • Gait analysis or documentation of abnormal gait
  • X-rays showing degenerative changes
  • Medical opinion on altered biomechanics

Hip Condition

DC: 5252 Max Rating: 90%
Caused By Strong Evidence

Medical Connection

Compensating for back pain alters hip mechanics and can cause or accelerate hip degeneration.

Evidence Tips

  • Documentation of altered gait
  • Imaging of hip joints
  • Medical opinion on compensatory mechanics

Tips for Filing Secondary Claims

  • Get a nexus letter: A medical opinion specifically stating your secondary condition is "at least as likely as not" caused by or aggravated by your primary condition is crucial.
  • Document the timeline: Show when your secondary condition developed relative to your primary condition. Earlier development strengthens the connection.
  • Include research: Medical studies showing the connection between conditions can support your claim. Your doctor can reference these in their nexus letter.
  • Be specific on VA Form 21-526EZ: When describing your condition, explicitly state it is "secondary to [your primary condition]" to ensure proper processing.
