§ 4.124a Schedule of ratings—neurological conditions and convulsive disorders.

Obturator nerve pain or damage

Inflammation or damage to the obturator nerve, which may cause pain or numbness in the inner thigh.

What the rating means

Obturator nerve pain or damage is rated under diagnostic code 8628, using the label "Neuritis" in VA's schedule for neurological conditions. VA rates this condition by looking at how much function the obturator nerve has lost. The two possible ratings are 10% and 0%. A severe to complete loss of function warrants a 10% rating. A mild or moderate loss of function results in a 0% rating. Because this is a peripheral nerve condition, VA's rules note that when only sensory function is affected — with no motor loss — the rating should be placed at the mild or at most the moderate level. The ratings above are for one side of the body. If both sides are involved, VA combines the two separate ratings and applies the bilateral factor.

Evidence that helps

To support a rating of 10%, medical evidence needs to show severe to complete loss of obturator nerve function. Nerve conduction studies or electromyography that document severely reduced or absent nerve signals can reflect this level of impairment. A physician's examination findings showing marked weakness of hip adduction, near-total sensory loss in the inner thigh, or significant gait difficulty tied to obturator nerve damage would also be relevant. If your condition is purely sensory — pain or numbness without motor loss — the regulation places the rating at mild or moderate, meaning evidence of sensory symptoms alone is unlikely to move the rating above 0%. Your own statements describing how pain, weakness, or numbness limits your daily activities or work tasks can help show the severity of functional loss, though those statements work best when they are supported by objective clinical findings in your medical records.

Secondary conditions

Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
