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

Ilio-inguinal nerve pain or damage

Inflammation or damage to the ilio-inguinal nerve, which may cause pain or numbness in the groin and upper inner thigh.

What the rating means

Ilio-inguinal nerve pain or damage is rated under diagnostic code 8630, using the neuritis formula. VA rates this condition by looking at how much function the ilio-inguinal nerve has lost. Two ratings are possible: 10% for severe to complete loss of function, and 0% for mild or moderate loss of function. Because the ilio-inguinal nerve is a sensory nerve, the regulation states that when the involvement is wholly sensory, the rating should be for the mild, or at most, the moderate degree. The ratings are for one side; if both sides are affected, VA combines the two ratings and applies the bilateral factor. The starting point at every level is how far your symptoms fall short of complete paralysis of the nerve.

Evidence that helps

Medical records that document the nature and extent of your nerve symptoms are central to any rating. A diagnosis of ilio-inguinal neuritis or nerve damage, along with a provider's description of whether the loss of function is mild, moderate, or severe, directly maps to the rating levels. Physical examination findings showing reduced or absent sensation in the groin, inner thigh, or scrotal or labial area help establish severity. Nerve conduction studies or other objective testing, if performed, can support the degree of impairment. Because the regulation limits a purely sensory nerve to mild or moderate at most, records that show any motor involvement would be relevant. Statements from you describing how pain or numbness affects your daily activities and work can help show the practical impact of your symptoms at each level.

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.
