Diabetes Mellitus C&P Exam Prep

HbA1c (Glycated Hemoglobin)

What it measures: 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.

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)

What it measures: 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).

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

Insulin Injection Frequency Assessment

What it measures: 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.

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

Hypoglycemic Episode and Hospitalization Count

What it measures: 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.

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

Ketoacidosis Episode and Hospitalization Count

What it measures: 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.

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

Activity Regulation Assessment

What it measures: 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.

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

10%

Diabetes mellitus manageable by restricted diet only. No insulin or oral hypoglycemic agents required.

From 38 CFR: Manageable by restricted diet only. Under 38 CFR - 4.119 DC 7913, this is the minimum compensable rating.

20%

Requiring one or more daily injection of insulin and restricted diet; OR oral hypoglycemic agent and restricted diet. Activity regulation is NOT required at this level.

From 38 CFR: Requiring one or more daily injection of insulin and restricted diet, or; oral hypoglycemic agent and restricted diet.

40%

Requiring one or more daily injection of insulin, restricted diet, AND regulation of activities (avoidance of strenuous occupational and recreational activities). No hospitalizations required at this level.

From 38 CFR: Requiring one or more daily injection of insulin, restricted diet, and regulation of activities.

60%

Requiring one or more daily injection of insulin, restricted diet, and regulation of activities WITH episodes of ketoacidosis or hypoglycemic reactions requiring one or two hospitalizations per year OR twice-monthly visits to a diabetic care provider, PLUS complications that would NOT be compensable if separately evaluated.

From 38 CFR: Requiring one or more daily injection of insulin, restricted diet, and regulation of activities with episodes of ketoacidosis or hypoglycemic reactions requiring one or two hospitalizations per year or twice a month visits to a diabetic care provider, plus complications that would not be compensable if separately evaluated.

100%

Requiring MORE THAN ONE daily injection of insulin, restricted diet, and regulation of activities WITH episodes of ketoacidosis or hypoglycemic reactions requiring at least THREE hospitalizations per year OR WEEKLY visits to a diabetic care provider, PLUS either progressive loss of weight and strength OR complications that WOULD be compensable if separately evaluated.

From 38 CFR: Requiring more than one daily injection of insulin, restricted diet, and regulation of activities with episodes of ketoacidosis or hypoglycemic reactions requiring at least three hospitalizations per year or weekly visits to a diabetic care provider, plus either progressive loss of weight and strength or complications that would be compensable if separately evaluated.

Insulin Dependence and Treatment Burden

How to describe it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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).

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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 it: 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.

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.

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.

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.
