How to file a VA cold injury residuals claim — Korean War + cold-weather operations under DC 7122

Step 1: Document your cold-exposure service period (Korean War + other cold-weather operations)

Qualifying cold-exposure service includes: (a) KOREAN WAR (June 27, 1950 - January 31, 1955) — winter combat operations especially Chosin Reservoir November-December 1950 ("Frozen Chosin"), winter retreat from Yalu River, eastern Korea winter operations 1951-1953; (b) WWII EUROPEAN THEATER POWs — German prison camps with inadequate winter clothing/food; (c) WWII PACIFIC THEATER cold operations — Aleutian Islands campaign (1942-1943), Attu, Kiska; (d) BATTLE OF THE BULGE (December 1944 - January 1945) — Ardennes winter combat; (e) BERLIN AIRLIFT cold-weather flight operations (1948-1949); (f) ALEUTIAN ISLANDS COAST GUARD operations; (g) MOUNTAIN WARFARE training/operations (10th Mountain Division, etc.); (h) SUBSEQUENT cold-weather operations + training (Greenland early-warning sites, Alaska bases, Norway exercises, Korean DMZ winter patrols 1953-present, Bosnia/Kosovo winter peacekeeping). Document via: DD-214 ports of departure/return, unit assignment records, OERs/NCOERs noting cold-weather duty, deployment medical records, POW certifications. CRITICAL: many Korean War veterans never had documented cold-injury treatment because medical care was minimal during winter combat — but the EXPOSURE itself + subsequent residual symptoms support claim.

Step 2: Identify your cold injury residual symptoms (5 categories under DC 7122)

Cold injury residuals under 38 CFR 4.104 DC 7122 cover 5 categories of chronic symptoms: (1) PERIPHERAL NEUROPATHY — numbness, tingling, burning sensations in affected extremities; nerve conduction studies show peripheral nerve damage; (2) HYPERSENSITIVITY TO COLD — cold intolerance, exaggerated cold response, Raynaud's phenomenon (blanching → blue → red color changes), chronic vasospasm; (3) CHRONIC PAIN — persistent pain in affected limbs, often worse in cold weather; (4) VASCULAR DAMAGE — peripheral artery disease, lymphedema, chronic venous insufficiency, skin discoloration, edema; (5) SKIN + NAIL CHANGES — scarring, atrophy, hyperhidrosis, brittle nails, fungal infections, skin breakdown. The "X-ray abnormalities, including osteoporosis, subarticular punched-out lesions, or osteoarthritis" symptom is also recognized in long-term cases. Document via: peripheral nerve conduction studies, vascular imaging (Doppler, ABI), photographic documentation of skin/nail changes, dermatology records, vascular medicine consultations.

Step 3: File VA Form 21-526EZ with explicit cold injury framing — claim PER LIMB

Submit VA Form 21-526EZ stating "[Affected limb] residuals of cold injury, secondary to [Korean War winter combat operations / POW cold exposure / specific cold-weather operation]." CRITICAL: cold injuries are rated PER AFFECTED LIMB. List EACH limb separately: "left foot residuals of cold injury," "right foot residuals of cold injury," "left hand residuals," "right hand residuals," etc. Each limb gets independent rating. Cold injury residuals can also affect: ears (frostbite), nose, face, fingers/toes individually. RATING TABLE under DC 7122: 10% = arthralgia, other pain, numbness, cold sensitivity OR x-ray abnormalities; 20% = same as 10% PLUS tissue loss, nail abnormalities, color changes, locally impaired sensation, hyperhidrosis, x-ray abnormalities; 30% = 20% factors PLUS one or more of: persistent peripheral nerve impairment, persistent muscle atrophy. Multiple limbs = multiple ratings combined via VA combined-rating math + bilateral factor (38 CFR 4.26) for paired limbs.

Step 4: At C&P exam — document symptoms + functional impact across all affected limbs

C&P examiner will use Cold Injury Residuals DBQ. Bring: (a) photographic documentation of skin/nail changes (often more impactful than examiner observation, especially for Raynaud's episodes which may not be active during exam); (b) symptom journal documenting per-limb cold sensitivity episodes, color changes, pain levels; (c) any vascular studies (ABI, Doppler), nerve conduction studies (NCS/EMG), dermatology records; (d) lay statements from spouse/family describing observed symptoms (Raynaud's episodes, sleep difficulty due to cold limbs, mobility limitations in winter). The examiner will check for sensation loss (monofilament testing), pulse strength, nail/skin appearance, color change response to cold. CRITICAL: warmth of exam room may mask Raynaud's + cold-sensitivity symptoms. Document via your home photos/journal, not just exam-day examination.

Step 5: Build secondary cascade + surviving family pathway

Cold injury residuals foundation opens secondary cascade: (a) PERIPHERAL NEUROPATHY (DC 8520 sciatic, DC 8716 ulnar, others) often progresses from cold injury residuals — if symptoms worsen over time, file secondary peripheral neuropathy claim; (b) PERIPHERAL ARTERY DISEASE (PAD, DC 7114) secondary to cold-injury vascular damage — common in elderly Korean War veterans; (c) ED + SMC-K STACKING — vascular ED secondary to cold-injury PAD auto-qualifies for SMC-K (~$132/mo bonus). See /api/v1/howto/file-ed-claim.json; (d) AMPUTATIONS — severe cold injury cases may have eventual amputations, rated under amputation tables; (e) DEPRESSION/anxiety secondary to chronic pain + functional limitation. SURVIVING FAMILY PATHWAY: deceased Korean War veterans whose deaths involved cardiovascular disease, peripheral artery disease, amputation complications, or sepsis from skin breakdown may have cold-injury-related cause-of-death pathway. Surviving spouse files DIC via VA Form 21P-534EZ — see /api/v1/howto/file-survivor-claim.json + CHAMPVA via VA Form 10-10D — see /api/v1/howto/apply-champva-healthcare.json. Many Korean War veteran families don't realize 1980s-2010s cardiovascular deaths may qualify for retroactive DIC.
