What to Expect During Your Exam

Exam Overview

To document the type, severity, treatment requirements, complications, and functional impact of your Diabetes Mellitus for VA disability rating purposes under Diagnostic Code 7913. The examiner will assess how your diabetes is managed, whether you require insulin and/or diet restrictions, whether you have had hypoglycemic or ketoacidotic episodes requiring hospitalization, and whether compensable complications exist.

What the examiner evaluates:

  • Confirmed diagnosis of Type I or Type II Diabetes Mellitus and date of diagnosis
  • Current treatment regimen: diet-only, oral hypoglycemic agents, insulin (frequency and number of injections per day)
  • Whether activities must be regulated or restricted due to diabetes
  • Frequency and severity of hypoglycemic reactions, including hospitalizations
  • Frequency and severity of ketoacidotic episodes, including hospitalizations
  • Frequency of visits to a diabetic care provider
  • Whether progressive loss of weight and/or strength is present
  • Most recent HbA1c value and fasting plasma glucose levels
  • Presence and severity of diabetic complications: peripheral neuropathy, nephropathy/renal dysfunction, retinopathy, erectile dysfunction, female sexual arousal disorder, cardiac conditions, hypertension, peripheral vascular disease, stroke, skin conditions
  • Whether complications are compensable if separately evaluated
  • Functional impact of diabetes and its complications on occupational and daily activities

The exam will involve both an interview (medical history, symptom review, treatment history) and a focused physical examination. The examiner may review your service treatment records, VA medical records, and any private medical records submitted. Bring a list of all current medications, recent lab results (HbA1c, fasting glucose), and records of any hospitalizations for hypoglycemia or ketoacidosis. In most states, you have the right to record this examination - notify the examiner at the start.

Typical duration: 30-45 minutes

HbA1c (Glycated Hemoglobin)

Average blood glucose control over approximately the prior 2-3 months. A value of 6.5% or greater on two or more occasions confirms the diagnosis of diabetes mellitus.

What to expect:

The examiner will record your most recent HbA1c from your medical records. This is a blood test - no repeat testing will be performed at the C&P exam itself. Bring copies of your most recent lab results.

Key thresholds:

  • 6.5% or greater on 2+ occasions — Confirms diagnosis of Diabetes Mellitus for rating purposes
  • Persistently elevated despite treatment — Supports documentation of poorly controlled diabetes, potentially supporting higher rating tiers

Tips:

  • Bring printed lab results showing your HbA1c values with dates
  • If your HbA1c has been consistently elevated, note this pattern to the examiner
  • Do not skip insulin or alter your routine before the exam - the exam should reflect your true condition

Pain considerations: Not applicable for this test; however, document any symptoms of hyperglycemia (fatigue, blurred vision, excessive thirst/urination) that accompany elevated HbA1c values.

Fasting Plasma Glucose (FPG)

Blood glucose after fasting for at least 8 hours. A value of 126 mg/dL or greater on two or more occasions is a diagnostic criterion for diabetes mellitus.

What to expect:

The examiner will record the most recent fasting plasma glucose value from your records. No new glucose tolerance test will be ordered solely for rating purposes per 38 CFR Note (2).

Key thresholds:

  • 126 mg/dL or greater on 2+ occasions — Confirms diagnosis of Diabetes Mellitus
  • 200 mg/dL random plasma glucose with classic symptoms — Alternative diagnostic confirmation of Diabetes Mellitus

Tips:

  • Bring your most recent fasting glucose lab results to the exam
  • If you have a glucometer log, bring it - patterns of high readings support severity documentation
  • Mention any episodes of hyperglycemia requiring emergency care

Pain considerations: Note any physical symptoms that accompany glucose spikes, such as headaches, extreme fatigue, blurred vision, or difficulty concentrating.

Insulin Injection Frequency Assessment

Whether you require one or more than one daily injection of insulin, which is a primary driver of the 40% and above rating tiers under DC 7913.

What to expect:

The examiner will ask about your insulin regimen - type of insulin, number of injections per day (or use of insulin pump), and whether this is required alongside dietary restriction and activity regulation.

Key thresholds:

  • One or more daily insulin injections + restricted diet — Minimum criteria for 20% (with oral agent) or 40% (insulin + restricted diet + regulated activities)
  • More than one daily injection + restricted diet + regulated activities + hospitalizations/weekly provider visits + weight/strength loss or compensable complications — Supports 100% rating

Tips:

  • Bring your current prescription bottles or pharmacy printout showing insulin type and prescribed dosage
  • If you use an insulin pump, explain that it delivers multiple basal/bolus doses - the VA considers this equivalent to multiple daily injections
  • Specify the exact number of injections per day (e.g., basal once + bolus with each meal = 4 injections daily)

Pain considerations: Describe any pain, bruising, lipodystrophy, or skin complications at injection sites.

Hypoglycemic Episode and Hospitalization Count

The frequency and severity of low blood sugar reactions requiring medical intervention, which directly determines eligibility for the 60% and 100% rating tiers.

What to expect:

The examiner will ask how often you have hypoglycemic reactions, whether they required emergency room visits or hospitalizations, and how many times in the past 12 months. They will also ask about visits to a diabetic care provider.

Key thresholds:

  • 1-2 hospitalizations per year for hypoglycemia OR twice-monthly provider visits + non-compensable complications — Supports 60% rating
  • 3+ hospitalizations per year for hypoglycemia OR weekly provider visits + compensable complications + weight/strength loss — Supports 100% rating

Tips:

  • Bring hospital discharge summaries, ER visit records, or ambulance call logs documenting hypoglycemic episodes
  • Count ALL visits to your diabetic care provider - endocrinologist, primary care diabetes management, diabetes nurse educator
  • Document episodes where you required assistance from another person even if you did not go to the hospital
  • Note episodes of loss of consciousness, seizure, or inability to self-treat

Pain considerations: Describe physical symptoms during hypoglycemic episodes: sweating, shakiness, confusion, heart palpitations, weakness, inability to function.

Ketoacidosis Episode and Hospitalization Count

The frequency of diabetic ketoacidosis (DKA) episodes requiring hospitalization, relevant to 60% and 100% rating tiers.

What to expect:

The examiner will ask about DKA episodes: symptoms, how often they occur, and whether they required hospitalization. This applies primarily to Type I diabetes but can occur in Type II.

Key thresholds:

  • 1-2 hospitalizations per year for DKA — Contributes to 60% rating criteria
  • 3+ hospitalizations per year for DKA — Contributes to 100% rating criteria

Tips:

  • Bring hospital records documenting each DKA admission with dates
  • Describe warning signs you experience (nausea, vomiting, abdominal pain, fruity breath, extreme thirst)
  • Note any DKA episodes treated in the ER but not resulting in inpatient admission - these still demonstrate severity

Pain considerations: Describe the physical experience of DKA: abdominal pain, vomiting, confusion, extreme weakness, and recovery time after each episode.

Activity Regulation Assessment

Whether your diabetes requires you to avoid strenuous occupational and recreational activities, which is a criterion that distinguishes the 40% from the 60%/100% tiers.

What to expect:

The examiner will ask whether your doctor has instructed you to avoid or limit strenuous activities and how this affects your work and daily life.

Key thresholds:

  • Must regulate activities (restrict strenuous occupational/recreational activities) — Required element for 40%, 60%, and 100% ratings when combined with insulin and diet

Tips:

  • Bring documentation from your treating physician stating activity restrictions
  • Be specific: 'My doctor told me I cannot do jobs requiring heavy lifting, prolonged standing, or work in extreme heat due to risk of hypoglycemia'
  • Describe how activity restrictions impact your current or former employment

Pain considerations: Describe fatigue, weakness, or risk of hypoglycemia that necessitates activity restrictions, and how these symptoms manifest during and after exertion.

How to Describe Your Symptoms

Insulin Dependence and Treatment Burden

How to describe:

Describe exactly how many insulin injections you administer per day, what types of insulin (basal, bolus, correction), the times of day, and that this is a medical requirement prescribed by your doctor. If you use an insulin pump, explain that it administers continuous basal insulin plus bolus doses at meals - this constitutes multiple daily insulin dosing. Mention the dietary restrictions you must follow and how they affect your daily choices.

Worst-day example:

“On my worst days, my blood sugar is unpredictable despite taking four insulin injections. I wake up with a high reading, correct with additional insulin, experience a crash mid-morning, must eat immediately to avoid losing consciousness, then spend the afternoon unable to concentrate or function at work. I am essentially managing a second full-time job just monitoring and adjusting my glucose.”

What the examiner listens for:

The examiner needs to document the number of daily injections, type of insulin, requirement for restricted diet, and whether activities must be regulated. They are specifically checking whether you meet the 'one injection' vs. 'more than one injection' threshold, and whether diet restriction and activity regulation are both present.

Understatements to avoid:

Do not say 'I just take a shot once a day and watch what I eat' without clarifying the full picture. If you also take a correction dose, that is an additional injection. If you take rapid-acting insulin with meals, that is multiple injections. Be precise.

Hypoglycemic Episodes

How to describe:

Describe the physical experience of your low blood sugar episodes: the warning signs (shaking, sweating, heart racing, confusion, vision changes), how quickly they come on, whether you can treat them yourself or need assistance, and whether any required emergency care or hospitalization. Give specific dates and counts of hospitalizations or ER visits in the past 12 months.

Worst-day example:

“My worst hypoglycemic episode was when my blood sugar dropped to 38 mg/dL overnight. I woke up confused and soaked in sweat. My spouse had to call 911 because I could not respond coherently. I was taken by ambulance to the ER, given IV dextrose, and held for observation. This has happened three times in the past year. Even mild lows leave me unable to drive, work, or care for myself for hours afterward.”

What the examiner listens for:

The examiner is counting hospitalizations per year and assessing frequency of severe reactions. They distinguish between self-treated lows (less significant) and episodes requiring ER visits, hospitalizations, or assistance from another person. They also assess whether episodes affect your ability to work.

Understatements to avoid:

Do not minimize by saying 'I just had a few low blood sugars.' Specify whether each required you to stop working, whether you needed glucagon or IV glucose, and whether emergency services were involved. Each hospitalization directly affects your rating tier.

Activity Regulation Requirements

How to describe:

Explain, with specific examples, how your diabetes requires you to avoid or significantly limit strenuous activities. Reference your doctor's explicit instructions and the real-world consequences. Describe both occupational limitations (cannot work jobs with heavy exertion, unpredictable schedules, or exposure to extreme temperatures) and recreational limitations (cannot hike, play sports, or engage in prolonged physical activity without risk of severe hypoglycemia).

Worst-day example:

“I used to work in construction but had to change careers because physical exertion causes my blood sugar to crash unpredictably. My endocrinologist has documented that I must avoid strenuous work. Even walking briskly for more than 20 minutes can cause a hypoglycemic episode. I cannot mow my own lawn without stopping to check my glucose multiple times and having fast-acting sugar on hand. I have completely stopped participating in sports I enjoyed before my diagnosis.”

What the examiner listens for:

The examiner needs to confirm that activity regulation is a medical necessity, not merely a personal choice. Documentation from a treating physician stating activity restrictions is ideal. They will note whether this is due to hypoglycemia risk, cardiovascular complications, or other diabetic factors.

Understatements to avoid:

Do not say 'I try to take it easy' - say 'my doctor has instructed me to avoid strenuous activities due to the risk of hypoglycemia.' The distinction between voluntary lifestyle choice and medically required restriction is critical for the 40%+ rating tiers.

Diabetic Complications

How to describe:

Systematically describe each complication you have been diagnosed with, the impact it has on your daily function, and whether it is being treated separately. Key compensable complications include: peripheral neuropathy (numbness, burning, pain in hands/feet), nephropathy (kidney function changes, protein in urine), retinopathy (vision changes, floaters, reduced acuity), erectile dysfunction, hypertension in the presence of diabetic renal disease, peripheral vascular disease, and cardiac conditions.

Worst-day example:

“The neuropathy in my feet is severe enough that I cannot stand on hard floors for more than 10 minutes without burning pain. At night, the sensations are so painful they wake me up. My nephrologist has noted early-stage kidney disease from the diabetes. My ophthalmologist diagnosed background diabetic retinopathy last year. Each of these complications was directly caused by my diabetes and is documented in my VA medical records.”

What the examiner listens for:

The examiner is determining whether each complication would be rated compensably (10% or higher) if evaluated separately - this is the distinction between the 60% tier (non-compensable complications) and 100% tier (compensable complications). They will check boxes for each complication present and may need to complete additional DBQs.

Understatements to avoid:

Do not fail to mention complications because you think they are 'just part of diabetes.' Even if a complication is non-compensable on its own, it still contributes to the 60% criteria. If it IS compensable separately, it is critical evidence for the 100% criteria and may also support separate service-connected claims.

Progressive Weight and Strength Loss

How to describe:

If you have experienced documented weight loss or loss of muscle strength attributable to your diabetes, describe the timeline, the amount of weight lost, and how your physical strength or stamina has declined. This is a specific criterion for the 100% rating and should be supported by medical records showing your baseline weight versus current weight.

Worst-day example:

“I have lost 22 pounds over the past 18 months that my endocrinologist attributes to my poorly controlled diabetes. I have also noticed significant weakness - I used to be able to do yard work for hours but now I tire within minutes. My muscle mass has visibly decreased and my doctor has noted this in my chart as diabetic cachexia.”

What the examiner listens for:

The examiner will document the percentage of baseline weight lost and whether there is objective evidence of strength decline. This element, combined with multiple daily injections, 3+ hospitalizations per year, and restricted diet/activities, supports the 100% threshold.

Understatements to avoid:

Do not omit weight loss data. If you have records showing a significant drop in weight, bring them. If your doctor has ever used the words 'progressive weight loss' in your chart, point the examiner to that documentation.

Provider Visit Frequency

How to describe:

Accurately describe how often you must visit your diabetic care providers - including your endocrinologist, primary care physician for diabetes management, diabetes nurse educator, and any other specialists managing diabetic complications. Twice-monthly visits support the 60% tier; weekly visits support the 100% tier.

Worst-day example:

“I see my endocrinologist every other week because my blood sugar is so difficult to control. I also have monthly visits with my nephrologist and quarterly ophthalmology checks for my retinopathy. My care team has told me this frequency of monitoring is medically necessary to prevent further deterioration.”

What the examiner listens for:

The examiner is counting how often you visit a diabetic care provider specifically. All visits to providers managing your diabetes or its complications should be counted. They will note the frequency against the twice-monthly (60%) and weekly (100%) thresholds.

Understatements to avoid:

Do not undercount your visits. Bring a printout of your appointment history if possible. Count visits to endocrinologists, diabetes nurses, and primary care physicians when the visit is for diabetes management.
