Acromegaly C&P Exam Prep

Serum IGF-1 (Insulin-Like Growth Factor-1)

What it measures: The primary biochemical marker for acromegaly activity; elevated IGF-1 confirms active disease or inadequate biochemical control after treatment.

What to expect: The examiner will review your most recent IGF-1 lab results. They may order new labs if recent results are unavailable. Normal ranges are age- and sex-adjusted. Values above the age-adjusted upper limit of normal indicate active or uncontrolled acromegaly.

Pain considerations: Lab draws themselves are minimally painful, but acromegalic arthropathy may make positioning for IV access uncomfortable - inform the examiner of any joint pain or limited mobility.

Glucose Tolerance Test (Oral Glucose Tolerance Test / fasting glucose)

What it measures: Evaluates whether acromegaly-induced growth hormone excess has caused glucose intolerance or overt diabetes mellitus. GH normally suppresses after an oral glucose load; failure to suppress confirms active acromegaly.

What to expect: The examiner will review existing OGTT results, fasting glucose, and HbA1c values. A new OGTT is unlikely during the C&P exam itself but existing results will be assessed. Impaired fasting glucose (100-125 mg/dL), impaired glucose tolerance (2-hour glucose 140-199 mg/dL), or diabetes (fasting -126 mg/dL or 2-hour -200 mg/dL) are all relevant findings.

Pain considerations: Not directly painful, but hypoglycemic episodes or hyperglycemia can cause fatigue, weakness, and cognitive difficulties - document these functional effects accurately.

Blood Pressure Measurement

What it measures: Documents the presence and severity of hypertension, which is a key criterion distinguishing 60% from 100% ratings under DC 7908.

What to expect: The examiner should take blood pressure at least three times during the visit (BP x3 is specifically referenced in the DBQ). Hypertension is generally defined as systolic -130 mmHg or diastolic -80 mmHg on multiple readings, or current use of antihypertensive medications.

Pain considerations: If acromegaly has caused carpal tunnel or peripheral neuropathy, inform the examiner that cuff placement on a specific arm may be uncomfortable.

Cardiac Evaluation / Echocardiogram Review

What it measures: Detects cardiomegaly (enlarged heart), left ventricular hypertrophy, diastolic dysfunction, or other cardiac complications caused by chronic GH/IGF-1 excess, which is a criterion for the 100% rating.

What to expect: The examiner will review any existing echocardiograms, cardiac MRI, chest X-ray findings, or cardiology notes documenting cardiomegaly. A physical cardiac exam may be performed. The DBQ specifically asks about cardiomegaly as an acromegaly finding.

Pain considerations: Cardiac symptoms such as exertional dyspnea, palpitations, reduced exercise tolerance, and peripheral edema should be described in detail - these are functional manifestations of cardiomegaly.

Visual Field Testing / Ophthalmologic Evaluation

What it measures: Detects evidence of increased intracranial pressure or direct compression of the optic chiasm by a pituitary macroadenoma, including bitemporal hemianopia, visual field defects, decreased visual acuity, or papilledema.

What to expect: The examiner will ask about visual symptoms and review any existing ophthalmology or neuro-ophthalmology records. Formal visual field testing (perimetry) is not typically performed during a C&P exam but existing results will be reviewed. The DBQ specifically asks about evidence of increased intracranial pressure such as visual field defects.

Pain considerations: Headaches from increased intracranial pressure can be severe and debilitating - describe pain intensity on worst days using a 0-10 scale, location (typically frontal or retro-orbital), frequency, and any associated nausea or vomiting.

Joint Examination / Arthropathy Assessment

What it measures: Documents the presence and severity of acromegalic arthropathy - a direct complication of chronic GH/IGF-1 excess causing cartilage hypertrophy, joint space widening followed by narrowing, osteophyte formation, and functional joint impairment.

What to expect: The examiner will assess joint range of motion, tenderness, swelling, deformity, and functional limitation. Commonly affected joints include the spine (particularly lumbar), hips, knees, shoulders, and hands. The examiner may note muscle wasting in proximal upper and lower extremities, which the DBQ specifically addresses.

Pain considerations: Acromegalic arthropathy pain may be worse with weight-bearing, after prolonged activity, or during weather changes. Describe pain at rest versus with activity, morning stiffness duration, and whether pain disrupts sleep. These are all DeLuca factors critical to documenting true functional impairment.

100%

Evidence of increased intracranial pressure (such as visual field defect), PLUS arthropathy, PLUS glucose intolerance, PLUS EITHER hypertension OR cardiomegaly. All four categories of findings must be present.

From 38 CFR: 38 CFR 4.119, DC 7908: 'Evidence of increased intracranial pressure (such as visual field defect), arthropathy, glucose intolerance, and either hypertension or cardiomegaly - 100%'

60%

Arthropathy, PLUS glucose intolerance, PLUS hypertension. All three must be present. Cardiomegaly and evidence of increased intracranial pressure are NOT required at this level, distinguishing 60% from 100%.

From 38 CFR: 38 CFR 4.119, DC 7908: 'Arthropathy, glucose intolerance, and hypertension - 60%'

30%

Enlargement of acral parts (hands, feet, jaw, facial features, soft tissue) OR overgrowth of long bones. This is the minimum compensable rating and reflects structural changes without the full constellation of organ system complications required for higher ratings.

From 38 CFR: 38 CFR 4.119, DC 7908: 'Enlargement of acral parts or overgrowth of long bones - 30%'

Joint Pain and Arthropathy

How to describe it: Describe each affected joint specifically - location, character of pain (aching, sharp, grinding), what makes it worse (walking, climbing stairs, prolonged standing, repetitive use), what provides partial relief, and how it limits your function. Use specific examples such as 'I cannot stand for more than 20 minutes without knee pain forcing me to sit down' or 'I wake up with hip stiffness that takes 45 minutes to improve every morning.'

Example: On my worst days, the joint pain in my knees and lower back is so severe that I cannot get out of bed without assistance. My hands are so stiff and swollen in the morning that I cannot grip a coffee cup for the first hour. Walking more than half a block causes me to limp and forces me to stop. The pain is a 7-8 out of 10 and does not fully resolve with my pain medications.

Examiner listens for: Frequency and duration of joint pain episodes, which joints are affected, degree of functional limitation, use of pain medications or assistive devices, effect on employment and activities of daily living, and whether symptoms have worsened over time.

Avoid: Do not describe only your average or good days. Do not minimize joint stiffness by saying 'it loosens up after a while' without explaining the duration and functional impact of that stiffness. Do not omit joints that are less severely affected - document all affected joints.

Visual Symptoms and Headaches (Increased Intracranial Pressure)

How to describe it: Describe any changes in peripheral vision, episodes of visual blurring, double vision, or loss of visual field. Characterize headaches by location (frontal, behind the eyes, top of head), severity on a 0-10 scale, frequency (daily, weekly), duration, associated symptoms (nausea, vomiting, light sensitivity), and what treatments provide partial relief. Note whether headaches were present before diagnosis or have changed after treatment.

Example: My worst headaches occur several times per week. They feel like intense pressure behind my eyes and across my forehead, reaching 8 out of 10 in severity. They last 4-6 hours and force me to lie down in a dark room. I have noticed that my peripheral vision on the right side seems narrower than it used to be, and my eye doctor noted changes on my visual field test last year.

Examiner listens for: Documented visual field defects, papilledema on fundoscopic exam, history of symptoms consistent with raised intracranial pressure such as positional headache or morning headache, and correlation between pituitary tumor size and neurological symptoms.

Avoid: Do not dismiss headaches as 'just stress' or 'typical migraines' without noting their association with your acromegaly diagnosis. Do not omit visual changes even if they seem minor - even subtle peripheral vision changes are clinically significant under DC 7908.

Glucose Intolerance and Metabolic Symptoms

How to describe it: Describe symptoms of high blood sugar including excessive thirst, frequent urination, fatigue, blurred vision, difficulty healing cuts or bruises, and numbness or tingling in extremities. Specify all medications used to manage blood sugar. If you have a glucometer, describe your typical fasting and post-meal glucose readings. Note dietary restrictions required due to glucose intolerance.

Example: When my blood sugar runs high, I feel exhausted no matter how much sleep I get, my vision blurs, and I am constantly thirsty and urinating every hour. On my worst days the fatigue is so severe that I cannot work a full day or concentrate on tasks. My fasting glucose has been as high as 160 mg/dL and my HbA1c was 7.2% at my last test.

Examiner listens for: Laboratory confirmation of impaired fasting glucose, OGTT results, HbA1c values, current glucose-lowering medications, and whether diabetes is secondary to acromegaly versus pre-existing or independently caused.

Avoid: Do not say 'I manage it fine with diet' without also describing the significant dietary restrictions and lifestyle modifications required. Do not fail to mention if you have been prescribed any diabetes medications, even if they are considered mild or low-dose.

Hypertension and Cardiovascular Symptoms

How to describe it: State your diagnosis of hypertension, all antihypertensive medications, typical blood pressure readings, and any cardiovascular symptoms including exertional chest pain, shortness of breath, palpitations, reduced exercise tolerance, or ankle swelling. If you have cardiomegaly, describe how it limits your physical activity and daily function.

Example: Even on my blood pressure medications, my BP frequently reads 145/92 at home. When I try to walk up a flight of stairs, I become short of breath and my heart races. I used to be able to walk a mile without stopping; now I am winded after a block. My cardiologist told me my heart is enlarged due to the acromegaly and I have diastolic dysfunction.

Examiner listens for: Documented hypertension on three readings or confirmed on antihypertensive therapy, echocardiographic evidence of cardiomegaly or cardiomyopathy, cardiology records, and functional cardiac limitations.

Avoid: Do not omit hypertension because it is 'controlled' with medication - controlled hypertension still counts as hypertension under VA rating criteria. Do not fail to bring echocardiogram results showing cardiomegaly.

Acral Enlargement and Physical Changes

How to describe it: Describe measurable, concrete examples of physical changes caused by acromegaly: shoe size increase (e.g., went from size 9 to size 13), ring size increase, hat size change, jaw growth requiring dental work or difficulty chewing, changes in facial appearance noted by others. Describe any functional problems caused by enlarged hands or feet such as difficulty with fine motor tasks, fitting in standard equipment, or shoe-related skin problems.

Example: My hands have grown so large that I can no longer use standard work gloves and need custom-fitted gloves. My shoe size increased three sizes over five years and my feet are constantly painful from the structural changes. My jaw has grown to the point that my teeth no longer align properly and I have had to undergo dental work twice because of it. My wife and colleagues have commented on the visible changes in my facial features.

Examiner listens for: Physical examination findings documenting prognathism, frontal bossing, enlarged hands and feet, coarse facial features, and skin changes. Patient-reported functional limitations from structural changes. Comparison to pre-illness photographs or shoe/clothing records if available.

Avoid: Do not minimize physical changes by focusing only on cosmetic impact - emphasize functional limitations. Do not fail to bring before-and-after photographs if available, as these provide compelling objective evidence of acral enlargement.

Fatigue, Weakness, and Functional Impact

How to describe it: Acromegaly causes profound fatigue through multiple mechanisms including sleep apnea, metabolic disruption, cardiac dysfunction, and muscle changes. Describe fatigue severity using concrete functional terms: how many hours per day you can be productive, whether you require rest periods, how fatigue affects your employment, and whether it is worse on certain days or after activity.

Example: On my worst days, which occur at least 3-4 times per week, the fatigue is so overwhelming that I cannot function after noon. I require 1-2 hours of rest in the afternoon just to manage basic self-care. I have been unable to maintain full-time employment because of unpredictable fatigue crashes. Even after 9 hours of sleep, I wake feeling exhausted due to my sleep apnea which is a direct result of my acromegaly.

Examiner listens for: Impact of fatigue on employment and daily activities, relationship between acromegaly and sleep apnea, proximal muscle weakness documented on physical exam, and whether the veteran requires accommodations or assistance with activities of daily living.

Avoid: Do not describe fatigue only as 'feeling tired' - use functional terms that quantify the impact. Do not omit sleep apnea if present, as it is a recognized complication of acromegaly and contributes to fatigue severity.
