Paralysis of posterior tibial nerve (DC 8525)

Body system: Neurological Conditions and Convulsive DisordersRegulation: 38 CFR § 4.124a

Diagnostic Code 8525 covers paralysis of the muscles in your foot, specifically those that control the bottom (sole) of your foot and your toes. The VA rates this condition from 10% to 30% depending on how severe the paralysis is and how much it affects your ability to move your foot and toes. A 30% rating means complete paralysis with painful, burning sensations and inability to flex your toes, while 10% represents mild paralysis with some muscle weakness.

Rating levels

  • 30% — Complete paralysis of the posterior tibial nerve means you cannot move any of the muscles in the bottom of your foot, and you may experience severe burning or shooting pain. Your toes cannot bend downward, you have trouble moving your foot toward the center of your body (adduction), and you cannot point your foot downward (plantar flexion) properly. This represents total loss of function of this nerve with significant disability in foot movement and often chronic pain.
  • 20% — Your posterior tibial nerve (the nerve that runs along the inside of your ankle and controls certain foot muscles) is severely damaged but not completely destroyed. You would have significant weakness in your foot muscles that control pointing your toes downward and inward, along with numbness or tingling on the bottom of your foot, but you still retain some nerve function and muscle control.
  • 10% — This rating applies when you have moderate nerve damage to the posterior tibial nerve (the nerve that runs along the inside of your ankle and controls certain foot muscles) that causes noticeable problems but doesn't completely disable the nerve's function. You would experience symptoms like partial weakness in your foot muscles, some numbness or tingling in your foot, and difficulty with certain foot movements, but you still retain some normal nerve function and muscle control.
  • 10% — You have mild damage to the posterior tibial nerve (a nerve that runs along the inside of your ankle and controls certain foot muscles), but the nerve still works partially. This means you might experience some weakness when pointing your toes downward or turning your foot inward, along with possible numbness or tingling on the bottom of your foot, but these symptoms don't severely limit your daily activities.
