What to Expect During Your Exam
Exam Overview
To evaluate the nature, severity, and functional impact of Peripheral Artery Disease (PAD), also known as Arteriosclerosis Obliterans, for VA disability rating purposes under Diagnostic Code 7114. The examiner will document objective findings, vascular testing results, symptoms, and how the condition limits daily activities and work.
What the examiner evaluates:
- Presence and severity of intermittent claudication (leg pain with walking or exertion)
- Constant pain at rest indicating critical limb ischemia
- Ankle-Brachial Index (ABI) measurements for both lower extremities
- Toe pressure and transcutaneous oxygen tension (TcPO2) values
- Presence of trophic changes (hair loss, skin discoloration, nail thickening, skin atrophy)
- Persistent coldness of affected extremities
- Presence and severity of deep ischemic ulcers or gangrene
- Diminished or absent peripheral pulses
- Numbness, paresthesia, or weakness in affected extremities
- Deep aching or burning pain character and distribution
- Presence of necrosis or prior amputation
- History of surgical interventions (bypass grafting, angioplasty, stenting, endarterectomy)
- Functional limitations including walking distance and ability to perform work or daily activities
- Use of assistive devices (cane, walker, wheelchair, crutches)
- Current medications and treatment compliance
- History of prior vascular procedures and outcomes
The exam will include both an interview portion and a physical examination. You will likely be asked to walk or perform some mild exertion so the examiner can assess claudication. Wear comfortable, loose-fitting clothing that allows easy access to your legs and feet. Do not apply heavy lotions or bandages to your legs before the exam. Bring all assistive devices you use regularly. The examiner may perform Doppler ultrasound or request recent vascular lab results.
Typical duration: 30-45 minutes
Ankle-Brachial Index (ABI)
The ratio of ankle systolic blood pressure to brachial (arm) systolic blood pressure. A normal ABI is 1.0-1.4. Values below 0.9 indicate PAD; values below 0.4 indicate severe, limb-threatening ischemia.
What to expect:
A technician or examiner will use a hand-held Doppler device and blood pressure cuffs placed at the ankle and arm. Both sides will be measured. The exam takes approximately 10-15 minutes. You will lie flat on an exam table. The test is non-invasive and not painful, though cuff inflation may be momentarily uncomfortable.
Key thresholds:
- 0.9-1.0 — Borderline/mild PAD - may support a lower rating if symptoms are minimal
- 0.7-0.89 — Mild-to-moderate PAD - claudication typically present; relevant to 20% rating
- 0.5-0.69 — Moderate PAD - significant claudication; supports 40% rating range
- 0.4-0.49 — Moderately severe PAD - rest pain often present; supports 60% rating
- < 0.4 — Severe/critical limb ischemia - rest pain, ulceration, or gangrene risk; supports 100% rating
Tips:
- Ensure you have not smoked or consumed caffeine for at least 2 hours before the exam, as both can affect peripheral vascular tone and artificially alter ABI values.
- If you have calcified vessels (common in diabetics), your ABI may be falsely elevated (above 1.4); mention this to the examiner and request toe-pressure testing as an alternative.
- Report any symptoms that occur during the test, including cramping or pain.
- Ask the examiner to document the specific numeric ABI values for both extremities - not just 'reduced' or 'normal.'
Pain considerations: If positioning for the test causes pain or worsens your symptoms, inform the examiner immediately. Document any claudication or leg pain that occurs during or after the test.
Toe Pressure (TP) and Toe-Brachial Index (TBI)
Systolic pressure at the great toe using a specialized small cuff. Normal toe pressure is above 50 mmHg. Values below 30 mmHg indicate critical ischemia. Particularly useful when ABI is unreliable due to calcified vessels.
What to expect:
A small blood pressure cuff is placed around the great toe. A photoplethysmography (PPG) sensor detects blood flow. The test is non-invasive. Toe pressures below 30 mmHg are associated with poor wound healing and risk of amputation.
Key thresholds:
- > 50 mmHg — Adequate perfusion - less likely to support severe rating on this measurement alone
- 30-50 mmHg — Borderline ischemia - supports moderate-to-severe symptoms
- < 30 mmHg — Critical limb ischemia - strongly supports 60-100% rating range
Tips:
- Request toe pressure testing if you have diabetes, end-stage renal disease, or known arterial calcification.
- Ensure feet are warm before testing - cold-induced vasoconstriction can falsely lower readings.
- Document bilateral toe pressures separately on the DBQ.
Pain considerations: Report any toe or foot pain present at rest before, during, or after testing. Rest pain is a critical symptom for higher rating levels.
Transcutaneous Oxygen Tension (TcPO2)
The partial pressure of oxygen diffusing through the skin, reflecting local tissue perfusion. Normal TcPO2 at the foot is above 40 mmHg. Values below 20-30 mmHg indicate critical ischemia and high amputation risk.
What to expect:
Electrodes are placed on the dorsum of the foot. The electrodes heat the skin slightly (to 44-C) to increase local blood flow before measuring oxygen levels. The test takes 20-30 minutes and is non-invasive.
Key thresholds:
- > 40 mmHg — Adequate tissue perfusion
- 20-40 mmHg — Impaired perfusion - moderate ischemia
- < 20 mmHg — Critical ischemia - high risk of tissue loss; supports highest rating levels
Tips:
- This test is particularly valuable if you have non-healing wounds or ulcers.
- Ensure the examiner documents both left and right foot TcPO2 values.
- Smoking reduces TcPO2; confirm any recent smoking history is documented for context.
Pain considerations: Electrode warming is typically well-tolerated. Report any increase in foot pain during the procedure.
Claudication Distance Assessment (Walking Test)
The distance or time a veteran can walk before onset of claudication pain (initial claudication distance) and the maximum walking distance before being forced to stop (absolute claudication distance). This directly correlates to rating criteria.
What to expect:
The examiner may ask you to walk in a hallway or on a treadmill and report when pain begins and when you must stop. Alternatively, they may ask detailed verbal questions about your walking capacity on a typical bad day.
Key thresholds:
- No claudication on flat surfaces — Consistent with 0-10% range if other findings minimal
- Claudication on flat surfaces after prolonged walking — Consistent with 20% rating
- Claudication on flat surfaces after less than 25 minutes walking OR limited to 1 city block — Consistent with 40% rating
- Claudication after less than 50 meters OR rest pain present — Consistent with 60-100% rating
Tips:
- Report your WORST DAY walking capacity, not your best or average day.
- Specify the exact distance or time before pain begins AND the distance you are forced to stop.
- Describe the character of the pain - cramping, burning, aching - and the specific muscle groups affected (calf, thigh, buttock).
- Note how long you must rest before pain resolves enough to walk again.
- Describe how claudication has changed over the past 6-12 months.
Pain considerations: Pain with walking is the hallmark of PAD claudication. Be specific: 'After walking approximately one city block (about 500 feet) on flat ground, I develop severe cramping and burning pain in both calves that forces me to stop and rest for 5-10 minutes before I can continue.'

How to Describe Your Symptoms
Claudication (Exertional Leg Pain)
How to describe:
Accurately describe the exact distance or time before pain begins, the type of pain (cramping, burning, aching, heaviness), the specific muscle groups affected (calf is most common; thigh or buttock if aortoiliac disease), which legs are affected, and how long you must rest before you can walk again. Always report your worst day, not your best day.
Worst-day example:
“On my worst days, I cannot walk more than about 50 feet from my front door to my mailbox before severe cramping and burning pain forces me to stop and grip something for support. I have to stand still for at least 10 minutes before the pain eases enough for me to take a few more steps. Going to the grocery store is impossible without a cart to lean on, and even then I can only manage one or two aisles before I must sit down. At its worst, even slow walking on flat ground causes pain within 30 seconds.”
What the examiner listens for:
Specific distances, specific time intervals, affected extremities, pain character, rest requirement, and consistency with vascular anatomy. The examiner is mapping your symptoms to the rating table thresholds.
Understatements to avoid:
Do not say 'I walk okay but just get tired.' Do not describe only your best days when you pushed through the pain. Do not underreport rest pain by saying 'it's just a little uncomfortable at night' - if you have pain at rest, say so clearly and describe its character and frequency.
Rest Pain
How to describe:
Rest pain in PAD is typically a burning or aching pain in the forefoot or toes that occurs at night in bed, often relieved by dangling the leg over the side of the bed (dependency). Describe when it occurs, how long it lasts, what you do to relieve it, whether it wakes you from sleep, and what pain medications you require.
Worst-day example:
“The burning pain in my foot wakes me up almost every night, sometimes multiple times. It feels like my toes are on fire. I have to hang my foot off the side of the bed or get up and walk a few steps - the weight of the blood flowing down gives brief relief. On my worst nights, the pain is a constant 8 out of 10 and I cannot sleep at all. I take [medication] but it only takes the edge off.”
What the examiner listens for:
Nocturnal occurrence, relief with dependency (limb dangling), need for analgesics including prescription pain medications, sleep disturbance, and functional impact on activities of daily living.
Understatements to avoid:
Do not minimize rest pain as 'just nighttime discomfort.' Rest pain is a critical marker for the 60%+ rating levels. Do not forget to mention sleep disruption caused by pain.
Trophic Changes and Skin Findings
How to describe:
Trophic changes are visible objective findings the examiner will look for, but you should proactively describe what you have noticed at home, including hair loss on the lower legs, shiny or thin skin, nail changes (thickened or slow-growing), skin color changes (pallor, cyanosis, or redness), and temperature differences between your feet and calves.
Worst-day example:
“I've noticed over the past two years that the hair on my lower legs and feet has almost completely stopped growing. The skin on my feet looks shiny and feels papery-thin. My toenails grow extremely slowly and are thick. When I hold both feet next to each other, the affected foot always feels noticeably colder. After I sit with my legs down, my foot turns a dusky reddish-purple color.”
What the examiner listens for:
Duration of changes, bilateral versus unilateral distribution, specific changes present (hair loss, nail changes, skin atrophy, color changes), and correlation with objective vascular exam findings.
Understatements to avoid:
Do not assume the examiner will notice all trophic changes on their own - point them out and describe when they started and how they have progressed.
Ulceration and Wound History
How to describe:
If you have had or currently have ischemic ulcers, describe their location (toes, heel, lower leg), size, depth, healing timeline, treatment required, recurrence history, and whether they required hospitalization or surgery. Ischemic ulcers are typically located at pressure points or distal areas and are painful, unlike venous ulcers.
Worst-day example:
“I developed an ulcer on my right great toe about eight months ago. It started as a small dark spot and opened into a wound about the size of a dime. It has not healed despite weekly wound care visits, use of a wound vac for six weeks, and two courses of antibiotics. My vascular surgeon said it may require amputation if it does not improve. The pain from the ulcer is constant and severe, a 7 out of 10 even with prescription pain medication.”
What the examiner listens for:
Location, size, depth, duration, treatment history, response to treatment, recurrence, and whether the wound qualifies as 'persistent' (not healing after standard treatment) which supports the 100% rating level.
Understatements to avoid:
Do not describe an ischemic ulcer as just 'a sore' or 'a cut.' Specify it was diagnosed by your vascular surgeon or wound care provider as an ischemic or arterial ulcer. Describe resistance to treatment accurately.
Functional Impact and Daily Activity Limitations
How to describe:
Describe specifically how PAD affects your ability to perform work duties, household chores, shopping, self-care, recreational activities, and social activities. Include how it affects your employment. Connect symptoms to specific functional limitations.
Worst-day example:
“On my worst days, I cannot stand in the kitchen long enough to cook a meal. I cannot walk the length of a parking lot without stopping for pain. I lost my job as a warehouse worker because I could not stand or walk for more than a few minutes at a time. I use a cane to help redistribute my weight and reduce pain when walking. My wife does all the grocery shopping because I cannot tolerate the walking. I sleep in a recliner chair most nights because lying flat makes the foot pain worse.”
What the examiner listens for:
Specific limitations, assistive device use, employment impact, activities of daily living affected, and whether the functional impact is consistent with the objective vascular findings documented on the DBQ.
Understatements to avoid:
Do not say 'I manage okay' or 'I just take it slow.' Describe what you CANNOT do, not just what you can tolerate with difficulty. The DBQ has a specific field for functional impact - ensure your examiner captures it accurately.
Persistent Coldness and Numbness
How to describe:
Persistent coldness of the affected extremity is an objective finding that also has a subjective component. Describe whether the coldness is constant or intermittent, which extremity, how far up the leg it extends, and whether it is accompanied by numbness, tingling, or paresthesia. These symptoms reflect inadequate peripheral perfusion.
Worst-day example:
“My right foot and lower leg are cold virtually all the time, even in warm weather. I wear socks to bed year-round and often use a heating pad, though my vascular doctor warned me to be careful with heat due to poor circulation. The bottom of my foot has areas that feel numb - I cannot always tell if I'm stepping on something sharp. The numbness extends up to about mid-calf.”
What the examiner listens for:
Constant versus intermittent coldness, laterality, extent, whether numbness is present and its distribution, and safety concerns related to impaired sensation (risk of undetected injuries).
Understatements to avoid:
Do not omit numbness or loss of sensation - these are important for both rating and safety documentation. Impaired sensation creates risk of undetected ischemic injury that can progress to ulceration.
Common Mistakes to Avoid
Describing average or best-day walking capacity instead of worst-day capacity
Rating criteria are based on the worst-day functional capacity as directed by M21-1. Veterans often minimize their condition by describing a day when they pushed through the pain. The examiner documents what you report, and if you report a higher functional capacity, you will be rated accordingly.
Instead: When asked how far you can walk, explicitly say: 'On my worst days, which happen [frequency], I can only walk [distance] before severe pain forces me to stop.' Then separately describe typical days. Use the phrase 'worst day' proactively.
Impact: All levels - especially the difference between 20% and 40%, and 40% and 60%
Failing to report rest pain
Rest pain (pain in the foot or toes at rest, especially at night) is the threshold symptom separating moderate PAD from critical limb ischemia. Failing to report it means the examiner cannot document it, and you will be rated at a lower level than your condition warrants.
Instead: Proactively tell the examiner: 'I also have pain when I am not walking - at night, my foot burns and aches even in bed.' Describe nocturnal rest pain, dependency relief, analgesic requirements, and sleep disruption.
Impact: 60% - rest pain is explicitly listed in the criteria for this level
Not bringing documentation of vascular studies or recent labs
The DBQ requires objective ABI values, toe pressures, and TcPO2 readings. If the examiner cannot obtain these at the time of the C&P exam, they may rely on older or missing data, potentially resulting in an inaccurate rating.
Instead: Bring copies of all recent vascular lab reports including ABI studies, duplex ultrasound reports, angiography results, and TcPO2 measurements. If no recent studies exist, ask your treating vascular surgeon for updated testing before your C&P exam.
Impact: All levels - objective data is required for accurate rating
Minimizing the impact on employment and daily activities
The DBQ has a specific section on functional impact. VA raters and the VASRD consider functional impairment when evaluating cardiovascular conditions. Veterans who say 'I'm doing okay' or 'I manage' allow the examiner to record minimal functional impact, which does not support higher ratings.
Instead: Explicitly describe what you cannot do: job duties you can no longer perform, household tasks you require assistance with, activities you have given up, and how your condition has changed your daily routine. Be specific and use concrete examples.
Impact: All levels - functional impact fields affect the overall picture presented to raters
Failing to disclose use of assistive devices
Use of a cane, walker, or wheelchair due to PAD is documented on the DBQ and reflects functional severity. If you use assistive devices but do not mention them, the examiner may not document them, underrepresenting your disability.
Instead: Bring all assistive devices you use to the exam. Tell the examiner: 'I use a [cane/walker] when walking because of the pain and instability from my PAD.' Explain how frequently you use the device and for what activities.
Impact: 40-100% - reflects significant functional limitation
Not describing bilateral involvement when both legs are affected
The DBQ documents each extremity separately. If both legs have PAD but you only describe the worse side, the examiner may not adequately document bilateral disease, which can affect both the rating and the documentation of total disability impact.
Instead: Describe symptoms in both extremities separately. Note which is worse and which is less affected. Use specific anatomical locations: 'My right calf claudicates after 100 feet; my left calf claudicates after 200 feet.'
Impact: All levels - bilateral disease is rated separately under DC 7114 for each extremity
Not disclosing surgical or procedural history
The DBQ specifically asks about prior vascular surgeries (bypass grafting, angioplasty, stenting, endarterectomy). Post-surgical results - whether improved, unchanged, or worsened - are critical to the rating picture. Examiners need to know if you have had procedures and whether they helped.
Instead: Prepare a written timeline of all vascular procedures including dates, facility, type of procedure, and outcome. Bring surgical records if available. Describe residual symptoms following any procedure.
Impact: All levels - procedure history informs rating continuity and current severity
Confusing PAD symptoms with other leg conditions during the exam
PAD claudication has specific characteristics (cramping with walking, relief with rest, no pain at rest in early stages) that differentiate it from spinal stenosis (neurogenic claudication), venous disease, or musculoskeletal pain. Using imprecise language can confuse the examiner's assessment.
Instead: Describe your PAD symptoms using vascular-specific language: location (calf, thigh, buttock), onset with walking, relief with rest, progression over time, and objective findings (coldness, color changes, hair loss). If you have multiple leg conditions, describe each separately.
Impact: All levels - accurate symptom characterization is essential for correct diagnostic coding

Your Rights During a C&P Exam
- You have the right to a thorough, accurate, and unbiased Compensation and Pension examination. The examiner must review all available evidence, including your service treatment records, VA medical records, and private medical records submitted to the VA.
- You have the right to record the C&P examination in most states. Check your state's single-party consent laws before the exam. If recording is permitted, inform the examiner at the start of the appointment.
- You have the right to request a new examination if the original exam was inadequate, the examiner was not qualified in vascular medicine, or significant symptoms were not addressed. File a Notice of Disagreement or request a supplemental claim with additional evidence.
- You have the right to submit a personal statement (VA Form 21-4138) describing your symptoms in your own words. This statement becomes part of your claims file and must be considered by the rater.
- You have the right to submit private medical opinions from your own treating vascular surgeon, cardiologist, or internist. A nexus letter or detailed medical opinion from your treating provider carries significant evidentiary weight.
- You have the right to obtain a copy of your completed DBQ through a FOIA/Privacy Act request. Review it for accuracy and completeness. If findings are inaccurate or incomplete, document the discrepancies in a statement to the VA.
- You have the right to bring a VSO (Veterans Service Organization) representative, accredited claims agent, or VA-accredited attorney to your appointment. Some facilities allow a support person to accompany you.
- Under the PACT Act and related legislation, veterans may have expanded eligibility for service connection for PAD related to toxic exposures (burn pits, Agent Orange, contaminated water). Discuss potential toxic exposure connections with your VSO or accredited representative.
- You have the right to a rating decision based on the benefit of the doubt. Under 38 CFR 3.102, when there is an approximate balance of positive and negative evidence, VA must resolve the question in your favor.
- You have the right to appeal any rating decision. Options include filing a supplemental claim with new evidence, requesting a Higher-Level Review, or filing a Board of Veterans' Appeals appeal. Each option has specific timeframes - consult an accredited representative.
- You have the right to total disability based on individual unemployability (TDIU) if PAD prevents you from maintaining substantially gainful employment, even if the scheduler rating does not reach 100%. This requires VA Form 21-8940.
- You have the right to request that both lower extremities be rated separately under DC 7114 if both are affected. Bilateral cardiovascular disability may be rated separately, potentially resulting in a combined higher disability rating.
- You have the right to Special Monthly Compensation (SMC) if your PAD has resulted in the loss of use of a hand, foot, or creative organ, or if you require the aid and attendance of another person due to the severity of your disability.
Related Conditions
- Hypertension (High Blood Pressure) Hypertension is a major risk factor and common comorbidity with PAD. Both share atherosclerotic pathology. Hypertension may be ratable separately under DC 7101 as a secondary condition to PAD or as an independent service connected disability.
- Coronary Artery Disease (Ischemic Heart Disease) PAD and coronary artery disease share the same underlying atherosclerotic disease process. Veterans with PAD have significantly elevated risk of myocardial infarction. Ischemic heart disease is separately ratable under DC 7005. Veterans with qualifying military service (Agent Orange, Gulf War, burn pit exposure) may have presumptive service connection for ischemic heart disease.
- Diabetes Mellitus Type 2 Diabetes is both a major risk factor for PAD and a condition that dramatically worsens PAD outcomes (accelerated atherosclerosis, impaired wound healing, neuropathy masking ischemic pain). If service connected diabetes caused or aggravated PAD, a secondary service connection claim is warranted. Separately ratable under DC 7913.
- Diabetic Peripheral Neuropathy Peripheral neuropathy (numbness, tingling, pain) can coexist with or mimic PAD symptoms and is commonly present in veterans with diabetic PAD. Must be distinguished from ischemic neuropathy in PAD. Separately ratable under neurological diagnostic codes if service connected diabetes is the cause.
- Thromboangiitis Obliterans (Buerger's Disease) Buerger's disease is an inflammatory vascular disease distinct from PAD but sharing some symptoms (claudication, rest pain, ulceration). It primarily affects younger smokers and involves small to medium vessels. It is rated under DC 7115. If initial diagnosis of PAD is reconsidered as Buerger's disease, re coding may be appropriate.
- Post-Phlebitic Syndrome (Chronic Venous Insufficiency) Chronic venous insufficiency can coexist with PAD (mixed arterial venous disease). Venous disease is separately ratable under DC 7121. Mixed disease complicates treatment (compression stockings may be contraindicated in severe PAD) and is important to document separately on the DBQ.
- Chronic Kidney Disease (Renal Insufficiency) PAD and chronic kidney disease frequently coexist due to shared atherosclerotic risk factors. Renal artery stenosis may accompany PAD. CKD can cause falsely elevated ABI readings (vascular calcification) in PAD patients, requiring alternative testing. May be separately ratable.
- Raynaud's Disease or Syndrome Raynaud's phenomenon (vasospastic episodes causing color changes and pain in digits with cold or stress) can coexist with or be confused with PAD affecting upper extremities. Rated separately under DC 7117 (primary Raynaud's) or DC 7118 (secondary Raynaud's). The same DBQ covers both conditions.
- Amputation (Lower Extremity) Ischemic amputation is a direct complication of severe, untreated, or treatment resistant PAD. If PAD has resulted in amputation of toes, foot, or limb, the amputation is separately ratable under the amputation diagnostic codes (5160 5156 series) and may qualify for Special Monthly Compensation (SMC k for loss of use, or SMC l and above for higher level losses).
- Aortic Aneurysm Aortic aneurysm (abdominal or thoracic) shares the same atherosclerotic etiology as PAD and is commonly found in veterans with PAD. Separately ratable under DC 7110 (aortic aneurysm). Aortoiliac PAD (Leriche syndrome bilateral leg claudication plus impotence) may indicate significant aortic or iliac artery disease.
