Diagnostic Code 7122 · 38 CFR §4.104
Cold injury residuals are the lasting effects of cold weather injuries such as frostbite, trench foot, or immersion foot that occurred during military service. These injuries damage blood vessels, nerves, and tissues in exposed areas, most commonly the hands and feet. Long-term residuals can include chronic pain, numbness, cold sensitivity, color changes, nail damage, joint stiffness, and skin problems. Each affected extremity is rated separately, so veterans with multiple affected hands and feet can receive multiple ratings.
