Diagnostic Code 8624 · 38 CFR §4.123
Neuritis of the internal popliteal (tibial) nerve (DC 8624) refers to inflammation of this nerve, causing pain, tenderness, and impaired function along its distribution. The internal popliteal nerve, commonly called the tibial nerve, runs behind the knee and down the back of the lower leg, controlling calf muscles for plantarflexion and providing sensation to the sole of the foot. Under VA regulations (38 CFR §4.123), neuritis characterized by loss of reflexes, muscle atrophy, sensory disturbances, and constant pain is rated on the same scale as incomplete paralysis under DC 8524. The maximum rating for neuritis without organic changes cannot exceed the moderate incomplete paralysis level.
