PIP for Peripheral Artery Disease (PAD) - Can You Claim?

Peripheral artery disease (PAD) restricts blood flow to your legs, causing pain, cramping and numbness when walking (intermittent claudication). In severe cases, it causes pain at rest, non-healing wounds and risk of amputation. PAD directly affects the PIP mobility component because it limits how far you can walk.

Which PIP Activities Does PAD Affect?

Moving Around (Activity 12) - This is the primary activity. PAD causes claudication - cramping leg pain that forces you to stop walking. The distance you can walk before pain stops you is your "claudication distance." If this is under 50 metres, you qualify for at least standard mobility. Under 20 metres qualifies for enhanced.

Be specific: "I can walk approximately 30 metres on a flat surface before severe cramping pain in both calves forces me to stop. I must stand still for 2-3 minutes until the pain subsides before I can continue. Even after resting, the pain returns after another 20-30 metres."

Preparing Food (Activity 1) - Standing at a worktop reduces blood flow to your legs, causing pain. If you need to sit down repeatedly while cooking, meals take much longer and some tasks become unsafe.

Washing and Bathing (Activity 4) - Standing in the shower causes leg pain. Foot care is critical with PAD (risk of non-healing wounds), adding extra time to your daily routine.

Managing Therapy (Activity 3) - Needing an aid or someone's help to manage medication (statins, blood thinners, cilostazol) is descriptor 3b for 1 point however long it takes. Wound care done at home with another person's help, or a prescribed home exercise programme you can only do with someone supervising, counts as therapy and is scored by the hours of that help under 3c to 3f. Vascular clinic appointments and angioplasty follow-ups are not therapy at home. Daily foot inspection is essential, but it is monitoring a health condition, not therapy: needing help with it is 3b for 1 point.

The Exercise Paradox

Doctors tell you to walk more to improve circulation. Assessors might say "if you can exercise, you can walk." These are different things. A supervised exercise programme where you walk until it hurts, rest, then walk again is medical therapy. Walking to the shops and back is a daily activity. You may be able to do the first under medical supervision but not the second reliably and safely.

Severe PAD - Critical Limb Ischaemia

If your PAD has progressed to critical limb ischaemia (pain at rest, ulcers, gangrene risk), your PIP claim is very strong. Rest pain affects sleep (affecting every activity through fatigue), wound care is intensive therapy and the risk of amputation means you need supervision for safety. Describe the severity clearly.

What Evidence Helps?

• Vascular consultant letters
• Ankle-brachial index (ABI) results
• Angiography or duplex scan results
• Claudication distance measured by physiotherapist
• Wound clinic records if applicable
• Smoking cessation records (shows engagement with treatment)

Fontaine Classification - Severity Standard

PAD severity is typically classified by Fontaine stages:

• Stage I: Asymptomatic. Rarely PIP-qualifying.
• Stage IIa: Mild claudication, walking over 200m before pain. May qualify with other conditions.
• Stage IIb: Moderate-severe claudication, less than 200m. Scores 4 points under descriptor 12b, or standard mobility if you cannot reliably manage 50m.
• Stage III: Ischaemic rest pain (pain at rest, worse at night). Likely to qualify for enhanced mobility.
• Stage IV: Ulceration or gangrene. Critical limb ischaemia. Likely to qualify for enhanced both.

Ask your vascular team for your Fontaine stage. Include with PIP application.

ABI (Ankle-Brachial Index) Interpretation

• ABI 0.9-1.4: Normal
• ABI 0.5-0.9: Mild-moderate PAD
• ABI under 0.5: Severe PAD - critical limb ischaemia threshold
• ABI under 0.3: Imminent limb loss risk without intervention

Low ABI is objective evidence of severity. Include with claim.

Critical Limb Ischaemia Detail

CLI is end-stage PAD requiring urgent intervention. Features:

• Rest pain in foot/toes (often worse at night, relieved by hanging leg down)
• Non-healing wounds or ulcers (often toes, foot)
• Gangrene (black tissue)
• High amputation risk if untreated
• Often requires revascularisation surgery or angioplasty
• May require amputation despite intervention

CLI patients typically qualify for enhanced both PIP components. Include vascular surgery letters.

Activity 12 Detail for PAD

• Descriptor b (4 points): Can walk 50-200m. Mild-moderate claudication.
• Descriptor c (8 points - standard mobility): Can walk 20-50m. Moderate-severe claudication.
• Descriptor d (10 points - standard mobility): Can walk 20-50m with aid (stick, frame). Severe claudication needing support.
• Descriptor e (12 points - enhanced): Cannot walk 20m safely. CLI or advanced PAD.
• Descriptor f (12 points - enhanced): Cannot stand, or cannot move more than 1m, even with an aid.

The reliability test matters - if walking 50m takes 5 minutes with multiple stops, your reliable distance is much less than 50m.

Wound Care and Activity 3

If you have PAD-related ulcers:

• Daily wound dressing changes (15-45 minutes)
• District nurse visits
• Wound clinic appointments
• Antibiotic courses for infections
• Specialised dressings (Aquacel, hydrocolloids)
• Compression bandaging if mixed venous/arterial

Activity 3 counts the hours another person spends helping with therapy at home, so time the nurse or carer's dressing changes: up to 3.5 hours a week of that help is descriptor c (2 points), more than 3.5 hours descriptor d (4 points), more than 7 hours descriptor e (6 points) and more than 14 hours descriptor f (8 points). Dressings you manage alone, clinic appointments and antibiotic courses do not add to those hours (help with antibiotics is descriptor b, 1 point).

Frequently Asked Questions

I had a stent. Does that mean I'm cured?

Not necessarily. Stents can re-block (restenosis), and PAD is a systemic disease affecting arteries throughout the body. If your claudication distance has improved but is still limited, you still qualify. Get your vascular consultant to confirm your current walking distance.

My claudication distance varies. What distance do I use?

Use your WORST typical day, not your best. If you can walk 100 metres on a good day and 20 metres on a bad day, and bad days happen 4 out of 7 days, describe the 20-metre distance as your majority-day experience.

I had bypass surgery - what happens to my PIP?

Recovery from bypass takes months. During recovery you have significant function limits. Long-term, many bypass patients have improved but residual walking limitation. PIP continues based on current function.

What if I had amputation for PAD?

See our PIP for amputation guide. PAD-related amputation usually qualifies for enhanced mobility and often enhanced daily living. Wound care for residual limb adds Activity 3 burden.

I have PAD plus diabetes - how do I describe this?

List both conditions. Diabetic PAD is often more severe and faster-progressing. Add diabetic neuropathy (sensory and motor), Charcot foot risk and chronic kidney disease if present. Combined impact usually qualifies for enhanced rates.

Should I include smoking history?

Yes, briefly. Smoking is a major PAD cause but the DWP cannot refuse PIP because of how you developed your condition. Demonstrating engagement with smoking cessation can show treatment adherence.

What about leg revascularisation - angioplasty?

Angioplasty/stenting often improves walking but restenosis rates are high (30-50% within 2 years). Multiple procedures often needed. Document procedures, current function and follow-up surveillance.
