What to Expect During Your Exam
Exam Overview
To evaluate the current severity of Beriberi (Thiamine/B1 deficiency) and any residual symptoms or complications resulting from the deficiency, in order to assign an accurate disability rating under Diagnostic Code 6300.
What the examiner evaluates:
- Confirmed diagnosis of Beriberi (Thiamine/B1 deficiency) and date of diagnosis
- Type of Beriberi present: dry (neurological), wet (cardiovascular), or Wernicke-Korsakoff syndrome
- Peripheral neuropathy findings including absent knee or ankle jerks and loss of sensation
- Presence of foot drop or atrophy of thigh or leg muscles
- Cardiovascular involvement including cardiomegaly, edema, or congestive heart failure
- Presence of anasarca (severe generalized edema)
- Wernicke-Korsakoff syndrome symptoms including confusion, memory loss, ataxia, and ophthalmoplegia
- Non-specific symptoms such as decreased appetite, weight loss, and general fatigue
- Symptoms such as weakness, fatigue, anorexia, dizziness, and heaviness in the limbs
- Mental symptoms including cognitive changes or memory impairment
- Impaired bodily vigor affecting ability to function
- Residual findings, signs, and symptoms following treatment
- Current medications used to treat the condition
- Impact of the condition on occupational and daily functioning
- Any co-existing nutritional deficiency conditions
- History including onset, course, and progression of the veteran's nutritional deficiency
Exam will be conducted by an Internal Medicine physician or Nutrition Specialist, either in person or potentially via telehealth. The examiner will conduct both an interview covering your history, symptoms, and functional impact, and a physical examination assessing neurological findings (reflexes, sensation, muscle strength), cardiovascular signs (heart size, edema), and general physical condition. Bring all documentation of your thiamine deficiency diagnosis, lab results, treatment records, and any records of residual symptoms.
Typical duration: 30-45 minutes
Deep Tendon Reflex Testing (Knee and Ankle Jerks)
Neurological integrity of peripheral nerves; absent or diminished reflexes indicate peripheral neuropathy consistent with dry Beriberi
What to expect:
The examiner will tap your knee and ankle tendons with a reflex hammer to assess the presence and vigor of reflexes. Absent or hypoactive reflexes are a key finding for Beriberi peripheral neuropathy.
Key thresholds:
- Absent knee or ankle jerks with loss of sensation — Supports 10% rating level for peripheral neuropathy findings
- Foot drop or atrophy of thigh or leg muscles — Supports 30% rating level for severe peripheral neuropathy
Tips:
- Do not tense your muscles before the reflex test, as this may mask the absence of reflexes
- Report if your reflexes have been documented as absent or diminished in prior medical records
- Mention any history of falls or difficulty lifting your foot that may indicate foot drop
- If reflexes appear normal at the exam but have been absent historically, tell the examiner your condition fluctuates
Pain considerations: Report any burning, tingling, or pain in your extremities that accompanies the neurological deficits, as neuropathic pain is a significant functional impairment even when reflexes appear normal on exam day.
Neurological Sensory Testing
Loss of light touch, vibration, proprioception, or pin-prick sensation in the extremities, particularly lower legs and feet, consistent with peripheral neuropathy from Beriberi
What to expect:
The examiner may use a tuning fork, cotton swab, or pin to test sensation in your hands and feet. You will be asked whether you can feel the stimulus and where sensation is reduced or absent.
Key thresholds:
- Reduced or absent sensation in bilateral lower extremities — Contributes to peripheral neuropathy findings supporting 10-30% rating
- Loss of proprioception causing balance impairment — Supports higher severity ratings and contributes to functional impairment documentation
Tips:
- Be specific about which areas feel numb, tingling, or burning - describe the exact location and extent
- If you experience 'stocking-glove' distribution numbness (feet and hands), clearly describe this pattern
- Report if sensory symptoms are worse at night, after walking, or with temperature changes
- Mention if sensory loss has caused you to sustain burns or injuries because you could not feel heat or pain
Pain considerations: Neuropathic burning pain in the feet and legs is a hallmark Beriberi symptom. Clearly describe the intensity, frequency, and impact of any burning sensations, as this affects daily functioning and sleep quality.
Muscle Strength Testing
Motor weakness in the extremities, particularly lower limbs; assesses for foot drop, proximal muscle atrophy, or inability to perform movements requiring strength
What to expect:
The examiner will ask you to push or pull against resistance with your legs and feet. They will observe your gait and may assess for foot drop by asking you to walk or lift your foot.
Key thresholds:
- Foot drop present (inability to dorsiflex foot) — Directly supports 30% rating level under DC 6300
- Atrophy of thigh or leg muscles — Directly supports 30% rating level under DC 6300
- General weakness and reduced muscle endurance — Supports lower rating levels and functional impairment documentation
Tips:
- Walk naturally when observed - do not compensate or mask a gait abnormality
- Report if you use any assistive devices such as a cane, ankle foot orthosis (AFO), or brace due to foot drop or weakness
- Describe how far you can walk before weakness forces you to stop
- Report any history of falls attributable to leg weakness or foot drop
Pain considerations: Weakness is often accompanied by heaviness and fatigue in the limbs. Describe how quickly your legs become exhausted, even during minimal activity, as this functional fatigue is distinct from simple deconditioning and is a recognized Beriberi symptom.
Cardiovascular Assessment (Wet Beriberi)
Heart size, edema, cardiac function, and presence of congestive heart failure or anasarca secondary to wet Beriberi
What to expect:
The examiner may auscultate your heart and lungs, assess for peripheral edema by pressing on your ankles and shins, and review any cardiac imaging or echocardiogram results in your records.
Key thresholds:
- Cardiomegaly without congestive heart failure — Supports 30% rating level under DC 6300
- Congestive heart failure, anasarca, or Wernicke-Korsakoff syndrome — Supports 100% rating level under DC 6300
Tips:
- Bring echocardiogram reports, chest X-ray results, or cardiology notes showing cardiomegaly or heart failure
- Report if you experience shortness of breath on exertion, orthopnea (difficulty breathing while lying flat), or paroxysmal nocturnal dyspnea
- Describe any history of swelling in your legs, abdomen, or entire body (anasarca)
- Report any history of hospitalization for heart failure that was attributed to or occurred alongside your Beriberi
Pain considerations: Cardiovascular symptoms in wet Beriberi cause significant functional limitation. Clearly describe how cardiac symptoms limit your ability to perform activities, walk distances, climb stairs, and complete daily tasks.
Mental Status and Cognitive Assessment (Wernicke-Korsakoff Evaluation)
Presence and severity of cognitive impairment, confabulation, memory deficits, confusion, and other neuropsychiatric manifestations of Wernicke-Korsakoff syndrome
What to expect:
The examiner may ask questions to test your memory and orientation, review records of neurological or psychiatric evaluations, and document any history of Wernicke's encephalopathy or Korsakoff psychosis.
Key thresholds:
- Marked mental changes / Wernicke-Korsakoff syndrome — Directly supports 100% rating level under DC 6300
- Mild mental symptoms or cognitive complaints — Supports lower rating tiers and may support secondary mental health claims
Tips:
- If you have a history of Wernicke's encephalopathy (acute episode with confusion, eye movement problems, ataxia), document this clearly
- Korsakoff syndrome (chronic memory disorder, confabulation) should be noted with any neuropsychological testing results
- Bring records of any psychiatric hospitalizations or neurological consultations related to your thiamine deficiency
- Have a family member or caregiver accompany you who can corroborate cognitive and behavioral changes you may not fully recognize yourself
Pain considerations: The psychological burden of cognitive impairment from Wernicke-Korsakoff syndrome, including inability to form new memories, confusion, and personality changes, causes significant occupational and social functional impairment that should be fully described.
Rating Criteria Breakdown
| Rating % | Criteria | Key Symptoms |
|---|---|---|
| 100% | Presence of congestive heart failure, anasarca, or Wernicke-Korsakoff syndrome. This represents the most severe manifestation of Beriberi, involving life-threatening cardiac decompensation or severe permanent neurological/psychiatric impairment. |
CFR: 38 CFR 4.88b, DC 6300: Rate 100% when congestive heart failure, anasarca, or Wernicke-Korsakoff syndrome is present. These findings represent the full, life-threatening expression of wet Beriberi or severe thiamine-deficiency-related neuropsychiatric disease. |
| 30% | Presence of cardiomegaly without congestive heart failure, OR peripheral neuropathy with foot drop or atrophy of thigh or leg muscles. This level reflects significant structural cardiac or neurological damage from Beriberi. |
CFR: 38 CFR 4.88b, DC 6300: Rate 30% when cardiomegaly without congestive heart failure is present, or when peripheral neuropathy has progressed to foot drop or muscular atrophy of the thigh or leg. |
| 10% | Peripheral neuropathy with absent knee or ankle jerks AND loss of sensation, without foot drop or muscle atrophy. This level reflects early or moderate neurological involvement from Beriberi. |
CFR: 38 CFR 4.88b, DC 6300: Rate 10% when peripheral neuropathy is present with absent knee or ankle jerks and loss of sensation, representing established neurological deficit without the motor involvement (foot drop/atrophy) required for 30%. |
| 0% | Active Beriberi diagnosis confirmed but symptoms such as weakness, fatigue, anorexia, dizziness, or heaviness in limbs are present without meeting criteria for peripheral neuropathy with absent reflexes, cardiomegaly, heart failure, or Wernicke-Korsakoff syndrome. A 0% rating still establishes service connection, which is important for future claims and secondary conditions. |
CFR: 38 CFR 4.88b, DC 6300: Non-compensable rating when Beriberi is confirmed but symptoms do not meet the threshold for peripheral neuropathy with absent reflexes, cardiomegaly, cardiac failure, or Wernicke-Korsakoff syndrome. Establishing service connection at 0% preserves the right to seek increased ratings if symptoms worsen. |

Establishing service connection at 0% preserves the right to seek increased ratings if symptoms worsen.
How to Describe Your Symptoms
Peripheral Neuropathy - Pain, Numbness, and Tingling
How to describe:
Describe the exact location, character, and intensity of nerve symptoms. Specify whether pain is burning, stabbing, aching, or electric-shock-like. Identify whether numbness follows a stocking-glove distribution. Explain how these symptoms change with activity, time of day, temperature, or rest.
Worst-day example:
“On my worst days, I wake up at 2 or 3 in the morning because my feet feel like they are on fire - a constant burning that goes from my toes up to my mid-shin on both sides. I cannot sleep more than a few hours without being woken by the pain. My feet feel so numb during the day that I do not feel the floor when I walk, which makes me shuffle and I have tripped multiple times. I cannot walk more than half a block before my legs feel like lead weights.”
What the examiner listens for:
Specific symptom character (burning vs. numbness), bilateral vs. unilateral distribution, impact on sleep and ambulation, history of falls related to sensory loss, and correlation between activity and symptom worsening.
Understatements to avoid:
Saying 'my feet tingle sometimes' instead of accurately describing the frequency, intensity, and functional impact. Avoid saying 'it's not that bad' if the symptom disrupts your sleep, limits walking, or has caused falls.
Motor Weakness and Foot Drop
How to describe:
Describe difficulty lifting the front of your foot when walking, tripping over flat surfaces or thresholds, the need for a brace or orthotic device, and any visible wasting or thinning of your leg muscles. Quantify how far you can walk before weakness forces you to stop.
Worst-day example:
“On my worst days, I cannot lift my right foot off the ground properly when I walk - it drags, and I have to swing my hip out to clear the floor. I have a prescription ankle-foot orthosis that I wear because without it I fall. My calves have visibly shrunk compared to what they were before, and my thighs have lost significant muscle. I can only walk about 100 feet before my legs give out completely.”
What the examiner listens for:
Clear description of gait impairment consistent with foot drop, use of compensatory movements or assistive devices, documented or visible muscle atrophy, and quantified walking tolerance.
Understatements to avoid:
Not mentioning the brace or AFO you wear. Saying 'I walk a little funny' instead of describing foot drop. Walking better than usual on exam day and not mentioning that today is not representative of your typical condition.
Cardiovascular Symptoms (Wet Beriberi)
How to describe:
Describe shortness of breath, at what level of exertion it occurs, whether you need to sleep with your head elevated, leg swelling, rapid or irregular heartbeat, and any hospitalizations for heart failure. Bring cardiology records and imaging reports.
Worst-day example:
“On my worst days, I cannot walk to my mailbox without stopping to catch my breath. I sleep with three pillows because if I lie flat I wake up gasping. My legs swell so badly that my socks leave deep indentations in my ankles and my shoes no longer fit. I have been to the emergency room twice for heart failure that my cardiologist attributed to my Beriberi.”
What the examiner listens for:
Exertional dyspnea, orthopnea, paroxysmal nocturnal dyspnea, edema distribution and severity, exercise intolerance measurements, and objective cardiac findings from prior testing.
Understatements to avoid:
Failing to bring echocardiogram or chest X-ray records. Not describing how cardiac symptoms interfere with daily living. Minimizing swelling because 'the medication helps some days.'
Wernicke-Korsakoff Cognitive and Mental Symptoms
How to describe:
Describe specific memory failures - inability to learn new information, filling in memory gaps with invented stories (confabulation), disorientation, and confusion. Describe eye movement problems or unsteady gait if present during Wernicke's episodes. Quantify how cognitive impairment affects your ability to work, manage finances, and maintain relationships.
Worst-day example:
“On my worst days, I cannot remember what I did an hour ago. I have stopped myself from driving because I have pulled into parking lots and not known where I was or why I was there. My family has had to take over all financial management because I mix up numbers and forget bills. I sometimes realize I have told a story that is completely wrong - I filled in gaps with things that never happened and believed them completely at the time.”
What the examiner listens for:
Specific memory patterns consistent with Korsakoff amnesia (anterograde more than retrograde), confabulation, insight into cognitive deficits, functional consequences of cognitive impairment, and history of Wernicke's encephalopathy episodes.
Understatements to avoid:
Saying 'my memory isn't great' without specific examples. Performing better on the day of the exam due to a good day and not noting this is atypical. Not bringing corroborating statements from family members.
General Symptoms - Fatigue, Weakness, and Impaired Bodily Vigor
How to describe:
Describe total-body fatigue that is disproportionate to activity level, the speed with which you become exhausted, inability to sustain work or household tasks, and the recovery time needed after minimal exertion. Differentiate this from normal tiredness by describing its constant, pervasive nature.
Worst-day example:
“On my worst days, getting dressed and making breakfast exhausts me to the point where I need to sit down and rest for an hour before I can do anything else. I used to work full-time as a warehouse supervisor, but I can no longer stand for more than 15 minutes, my hands and feet feel like they belong to someone else, and I feel dizzy when I stand up too quickly. My entire body feels heavy and depleted from the moment I wake up.”
What the examiner listens for:
Fatigue severity relative to baseline function, impact on occupational capacity, frequency and duration of rest periods needed, and relationship between fatigue and neurological or cardiac symptoms.
Understatements to avoid:
Describing fatigue as 'I get tired' without context. Not connecting fatigue to specific functional losses. Appearing more energetic at the exam than on a typical day without disclosing that today is not representative.
Common Mistakes to Avoid
Describing symptoms as they are on a good day rather than accurately representing the full range of your condition
C&P exams often occur on days when veterans have rested, prepared, and may feel better than average. The examiner is required to rate the average severity, and M21-1 guidance directs consideration of worst-day functioning.
Instead: Explicitly tell the examiner: 'Today is a better day than average. On my worst days, which happen [X] times per week/month, my symptoms are as follows...' Then describe your worst-day presentation accurately.
Impact: All levels - can prevent achieving any compensable rating or can result in an understated rating at any tier
Failing to disclose all symptoms and functional impacts because they seem unrelated or minor
Beriberi affects multiple body systems simultaneously. Veterans often do not connect cardiac symptoms, neurological symptoms, and cognitive symptoms as part of the same condition, leading to incomplete reporting.
Instead: Before the exam, write down every symptom you experience - neurological, cardiovascular, cognitive, digestive, and psychological - and bring the list. Mention all of them, even if you are unsure they are connected.
Impact: 30% and 100% - particularly affects whether the examiner documents cardiomegaly, foot drop, or Wernicke-Korsakoff findings
Not bringing objective medical evidence such as lab work, echocardiograms, nerve conduction studies, or neurology/cardiology records
The examiner fills in the DBQ based on both interview and available evidence. Without prior records documenting cardiomegaly, absent reflexes, or Wernicke-Korsakoff episodes, the examiner can only rate what is present on exam day, missing historical severity.
Instead: Gather all relevant records before the exam: serum thiamine levels, nerve conduction velocity (NCV) and electromyography (EMG) studies, echocardiograms showing cardiomegaly, neurology consult notes, and any hospitalization records for cardiac or neurological events.
Impact: 30% and 100% - particularly critical for documenting cardiomegaly, foot drop, atrophy, or Wernicke-Korsakoff syndrome
Not mentioning the use of assistive devices, braces, or compensatory strategies
The use of an ankle-foot orthosis for foot drop, a cane for ataxia, or a hospital bed at home due to orthopnea are objective markers of severity that directly support higher rating tiers but are often overlooked in the conversation.
Instead: Bring any prescribed assistive devices to the exam. List all devices in your symptom notes and tell the examiner: 'I use [device] because without it I [specific consequence such as fall, cannot breathe at night, cannot walk safely].'
Impact: 30% - foot drop and motor impairment tier
Accepting a diagnosis of 'residual' or 'resolved' Beriberi without documenting ongoing functional deficits
Even after thiamine supplementation corrects the acute deficiency, permanent residuals such as peripheral neuropathy, cardiomegaly, cognitive impairment, and muscle atrophy may persist and remain ratable under DC 6300.
Instead: Clearly document that while thiamine levels may now be normal, the damage caused by the deficiency - neuropathy, foot drop, heart enlargement, or Korsakoff memory impairment - persists and continues to cause functional limitation.
Impact: All rating levels - affects whether a compensable rating is maintained after treatment
Failing to address the functional and occupational impact of symptoms
The DBQ specifically asks the examiner to describe the impact of nutritional deficiency on occupational and daily activities. If you do not volunteer this information, the examiner may not fully capture it, reducing the documented severity.
Instead: Prepare specific examples: 'Because of my foot drop, I can no longer work on uneven surfaces, use ladders, or perform jobs that require prolonged standing.' Or: 'My memory impairment means I can no longer manage complex tasks or work in any supervisory role.'
Impact: All levels - critical for supporting higher ratings and establishing unemployability if applicable

After the Exam
Your Rights During a C&P Exam
- You have the right to have your claim decided based on the benefit of the doubt - when the evidence is in approximate balance, it must be resolved in your favor (38 CFR 3.102).
- You have the right to request a copy of your completed DBQ examination report through your accredited representative, VSO, or via a Freedom of Information Act (FOIA) request.
- In most states, you have the right to audio or video record your C&P examination. Verify your specific state's applicable law before the exam and notify the examiner in advance if you intend to record.
- You have the right to bring a support person, caregiver, or family member to your C&P examination. They may provide collateral history if invited to do so by the examiner.
- You have the right to challenge an inadequate examination - if the examiner did not conduct required physical assessments, failed to address all claimed symptoms, or produced a report that is conclusory without adequate rationale, you may request a new examination.
- You have the right to submit additional evidence - including private medical opinions, independent medical examinations (IMEs), buddy statements, and lay statements - at any point before a rating decision becomes final.
- You have the right to request that the VA obtain relevant records - including Social Security Administration records, private treatment records with your authorization, and federal treatment records - before your claim is decided.
- You have the right to accurate worst-day reporting - M21-1 guidance directs that ratings reflect the full disability picture, including the frequency and severity of your worst symptoms, not only how you appear on the day of examination.
- You have the right to file a Notice of Disagreement (NOD) or request a Higher Level Review (HLR) or Board of Veterans' Appeals (BVA) review if you disagree with any rating decision within the legally prescribed timeframes.
- You have the right to representation by an accredited VSO, claims agent, or attorney at no out-of-pocket cost for most VSO representation, and on a contingency basis for attorneys after a Notice of Disagreement has been filed.
Related Conditions
- Peripheral Neuropathy Peripheral neuropathy is a direct consequence of chronic Beriberi (dry Beriberi / thiamine deficiency). Neuropathy manifesting as absent reflexes, sensory loss, foot drop, and muscle atrophy is rated under DC 6300 itself, but if the peripheral neuropathy is separately established as distinct from Beriberi ratings, it may warrant separate evaluation under neurological diagnostic codes.
- Wernicke's Encephalopathy Wernicke's encephalopathy is the acute neurological emergency caused by severe thiamine deficiency, presenting with the classic triad of confusion, ophthalmoplegia, and ataxia. It is a direct manifestation of Beriberi and supports the 100% rating under DC 6300. Persistent cognitive residuals may also be ratable as Korsakoff syndrome.
- Korsakoff Syndrome (Korsakoff Psychosis) Korsakoff syndrome is the chronic neuropsychiatric sequela of Wernicke's encephalopathy, characterized by severe anterograde amnesia, confabulation, and personality changes. It represents the 'Wernicke Korsakoff syndrome' component of the 100% rating tier under DC 6300, and may also support additional or separate psychiatric ratings.
- Congestive Heart Failure Congestive heart failure is the most severe cardiovascular manifestation of wet Beriberi and directly supports the 100% rating under DC 6300. If heart failure persists as a separate, established cardiac condition after Beriberi treatment, it may also be ratable under cardiovascular diagnostic codes (DC 7000 7020), potentially as a secondary condition.
- Cardiomegaly Cardiomegaly (enlarged heart) is a structural cardiac manifestation of wet Beriberi resulting from high output cardiac strain. It is directly rated under DC 6300 at the 30% level. Persistent cardiomegaly after treatment may also be considered under cardiac diagnostic codes if it represents a permanently established secondary condition.
- Pellagra (Vitamin B3 / Niacin Deficiency) Pellagra is a related nutritional deficiency condition (DC 6303) evaluated on the same Nutritional Deficiencies DBQ. Veterans who developed Beriberi in circumstances of general nutritional deprivation (e.g., prisoner of war experience, combat deployment) may have also developed concurrent Pellagra or other co existing deficiencies.
- Avitaminosis (General Vitamin Deficiency) Avitaminosis (DC 6302) represents general vitamin deficiency and may co exist with or precede the specific diagnosis of Beriberi. It is evaluated on the same Nutritional Deficiencies DBQ. Veterans with a history of severe nutritional deprivation may have multiple simultaneous deficiency conditions.
- Depression and Anxiety (Secondary to Chronic Condition) Chronic pain from peripheral neuropathy, functional limitation from cardiac or neurological damage, and cognitive impairment from Wernicke Korsakoff syndrome can cause or contribute to secondary depression and anxiety. Veterans may consider filing a secondary service connection claim for mental health conditions caused or aggravated by their Beriberi.
- Unemployability (Individual Unemployability / TDIU) If Beriberi and its residuals (neuropathy, foot drop, cardiac limitation, cognitive impairment) prevent a veteran from maintaining substantially gainful employment, the veteran may qualify for Total Disability based on Individual Unemployability (TDIU) even if the schedular rating is below 100%. Veterans rated 60% or higher from a single condition, or 70% combined with at least one condition at 40%, may apply.
