Listing 4.11 Chronic Venous Insufficiency in 2026: Brawny Edema, Stasis Dermatitis, and 3-Month Ulcer Rule

By Anthony Albert, Benefits Research Director at Disability Exchange. Published July 10, 2026.

Chronic venous insufficiency (CVI) is one of the most common vascular problems in adults. Most cases are managed with compression stockings and lifestyle changes. But a minority progress to the kind of severe skin and tissue damage that SSA Listing 4.11 was written for. If you have deep venous incompetence or obstruction with either massive dense swelling or a chronic ulcer that will not heal, you can qualify for SSDI without a Residual Functional Capacity fight.

This article walks through the exact text of 4.11, what "deep venous system" incompetency or obstruction actually means, how SSA defines brawny edema in 4.00G3 (and why pitting edema does not count), the two paths (A and B), what the 3-month ulcer rule requires, how lymphedema is handled separately per 4.00G4, and what to do when your case does not meet 4.11 but has serious functional limits. Two real fact patterns show how a case wins or loses.

The exact text of Listing 4.11

Two elements are needed either way. First, you must have documented incompetency or obstruction of the deep venous system in a lower extremity. Second, you must satisfy either Path A (brawny edema) or Path B (varicosities + stasis dermatitis + ulceration).

Deep venous system incompetency or obstruction: what SSA is looking for

The venous system in your leg has three parts: superficial veins (great saphenous, small saphenous), deep veins (femoral, popliteal, posterior tibial, peroneal), and perforator veins that connect the two. Varicose veins alone involve the superficial system. Listing 4.11 is not about varicose veins. It is about the deep system.

Deep venous incompetency means the valves in the deep veins do not close properly, so blood pools in the leg with gravity. Deep venous obstruction means blood cannot flow back up through the deep system because of clot, scarring from prior deep vein thrombosis (DVT), or extrinsic compression like May-Thurner syndrome.

Diagnosis is by duplex ultrasound, the workhorse test for venous disease. The tech maps reflux and obstruction in each named deep vein. Reflux times greater than 500 milliseconds in the femoral or popliteal on Valsalva or manual compression signals incompetence. Non-compressibility signals obstruction. Sometimes CT venography, MR venography, or intravascular ultrasound (IVUS) is added for iliac vein assessment.

If your medical file only shows varicose veins on physical exam and no formal duplex, you do not have a documented 4.11 case yet. Ask your primary care doctor for a vascular ultrasound referral. If you have had DVT in the past, get post-thrombotic imaging.

Path A: Brawny edema at the right size and location

SSA Section 4.00G3 spells out what brawny edema is:

Read that twice. The typical CHF patient with 3+ pitting edema does not meet 4.11A. That kind of edema goes down at night, does not have skin pigmentation change, and pits when pressed. Brawny edema is a chronic tissue remodeling process. The leg is firm even in the morning. There is usually a rusty brown or purplish discoloration from hemosiderin deposition. The skin can feel like leather.

Path A also has strict location and size requirements.

• Option 1: The brawny edema must involve at least two-thirds of the leg between the ankle and knee. If your leg from ankle to knee is 15 inches long, you need at least 10 inches covered.
• Option 2: The brawny edema must involve the distal one-third of the lower extremity between the ankle and hip. If your leg from ankle to hip is 33 inches long, the distal 11 inches must be affected.

Both options describe extensive coverage. Isolated ankle swelling does not meet 4.11A no matter how firm it is. The physical exam or clinic note has to describe the extent by anatomic landmarks. A treating clinician's note that says "brawny non-pitting edema from ankle to mid-calf and up to just below the tibial tuberosity" describes roughly two-thirds coverage. A note that says "3+ pitting edema" is not the same and will not carry the case.

Path B: Varicosities plus stasis dermatitis plus a stubborn ulcer

Path B has three parts. All three are required.

Part 1: Superficial varicosities

Visible varicose veins on physical exam or ultrasound. These are the ropy dilated superficial veins that most people picture when they think of "varicose veins." They are the surface manifestation of the underlying deep venous problem. Documentation is usually straightforward: any vascular surgeon or primary care note describing them satisfies this part.

Part 2: Stasis dermatitis

Stasis dermatitis is the skin change of chronic venous hypertension. Classic findings are eczema-like scaling, brown or purple hemosiderin pigmentation (that rusty color), atrophie blanche (small white scars in the skin), and sometimes lipodermatosclerosis (a wooden feeling of the skin from fibrosis of the subcutaneous fat).

Look for these terms in your medical records:

• Stasis dermatitis
• Hemosiderin deposition or hemosiderosis
• Lipodermatosclerosis
• Atrophie blanche
• Venous eczema

Any of these signals stasis dermatitis. A dermatology or wound care specialist evaluation strengthens the file. Photographs help.

Part 3: Recurrent or persistent ulceration

This is the hard part of Path B. You need either recurrent ulceration or an ulcer that has not healed after at least 3 months of prescribed treatment.

Recurrent ulceration means you get ulcers over and over. The ulcer heals, then comes back, then heals, then comes back. There is no specific SSA number of episodes required, but treating provider records showing repeated ulcerations over several months build a strong case.

Persistent ulceration after 3 months of prescribed treatment means an ulcer that started, was treated for at least 12 weeks, and still has not closed. Prescribed treatment for venous ulcers usually includes:

• Compression therapy (multi-layer bandaging or high-strength stockings above 30 mmHg)
• Wound care (debridement, foam or hydrocolloid dressings)
• Leg elevation
• Treatment of any bacterial infection
• Referral to a wound clinic or vascular specialist

If your ulcer has not been on compression therapy, SSA will say the treatment was not adequate. Compression is the standard of care. Non-compliance with compression, unless you have documented arterial disease that contraindicates it (which is a legitimate medical reason), can be characterized as failure to follow prescribed treatment and hurt your claim.

Lymphedema is not Listing 4.11

Section 4.00G4b is clear: lymphedema does not meet 4.11. It can medically equal 4.11. If your primary problem is lymphedema (post-mastectomy, filariasis, congenital lymphedema, or radiation-related), SSA evaluates it under a medical equivalence framework. That is a harder case than a straight meet.

The distinction matters for documentation. If your diagnosis is lymphedema, expect SSA to look at:

• Underlying cause (post-surgical, infectious, congenital)
• Any listing the underlying cause might meet (for example, cancer under 13.00)
• Musculoskeletal impact under Listing 1.18
• Functional limitations for RFC

The equivalence argument for 4.11 comparison focuses on: is the skin change and functional interference of your lymphedema at least as severe as brawny edema plus ulceration? Photographs, treating specialist opinion, and functional assessments are what carry that argument.

When 4.11 does not fit: the RFC pathway

Most CVI cases do not meet 4.11 because the swelling is pitting rather than brawny, or the ulcer heals in less than 3 months, or the deep system is not fully involved. That does not end the case. It shifts to RFC.

Reasonable RFC restrictions in moderate to severe CVI:

• Sitting with legs raised at heart level for a portion of each hour
• No prolonged standing (more than 30 to 60 minutes without a break to sit and rest)
• No prolonged walking on hard surfaces
• Environmental restrictions on heat (heat worsens venous pooling)
• No use of ladders or scaffolds if there is any wound at risk of trauma
• Off-task time for dressing changes if an ulcer is present

These restrictions can drop you into sedentary or below-sedentary RFC. Combined with age, education, and prior work experience, the Medical Vocational Grid Rules can direct a finding of disabled. See our detailed walkthrough of Medical Vocational Grid Rules.

Post-thrombotic syndrome and 4.11

Post-thrombotic syndrome (PTS) is the chronic complication of DVT. About 20 to 40 percent of patients with symptomatic proximal DVT develop PTS within 2 years despite anticoagulation. Symptoms include leg heaviness, pain, swelling, and skin changes ranging from mild pigmentation to severe ulceration. PTS is the most common pathway into a 4.11 case.

If you have had a DVT and are now developing PTS features, do this now:

1. Get a repeat duplex ultrasound documenting residual thrombus, reflux, and obstruction.
2. Ask about iliac vein imaging if you had an ileofemoral DVT. May-Thurner syndrome and post-thrombotic iliac vein compression are treatable with venous stenting.
3. Start compression therapy at 20-30 mmHg minimum. If the leg tolerates and you have no arterial disease, go to 30-40 mmHg.
4. Document everything. Photos, exam findings, ulcer measurements, ABI to rule out arterial disease.

Common mistakes with 4.11 claims

1. Confusing pitting edema with brawny edema. Path A requires brawny. Pitting does not count.
2. Not documenting extent by anatomic landmarks. "Diffuse leg swelling" is not enough. The clinician has to describe the extent in terms of two-thirds ankle-to-knee or distal one-third ankle-to-hip.
3. Trying Path B without stasis dermatitis documented. All three sub-parts of Path B are required.
4. Filing before the ulcer has been treated for 3 months. Path B ulceration criterion requires either recurrent ulceration or an ulcer that has not healed after 3 months of prescribed treatment. Wait for the timeline to accrue, or use "recurrent" language if you have prior episodes.
5. Ignoring compression non-compliance. If your records show refusal or inability to wear compression, SSA will characterize the case as failure to follow prescribed treatment unless there is a documented medical contraindication.
6. Missing the deep venous system documentation. Varicose veins alone are not 4.11. You need duplex showing deep system incompetency or obstruction.

What to bring to the initial claim

• Duplex ultrasound report showing deep venous system findings.
• Any history of DVT with anticoagulation records.
• Vascular surgery or wound care clinic notes.
• Photos of the affected leg showing edema, pigmentation, and any ulcer.
• Wound measurements and treatment log (compression type and duration, dressing types, debridement history, culture results).
• Ankle-brachial index result confirming absence of significant arterial disease.
• Physical exam notes documenting brawny (non-pitting) edema with extent by anatomic landmark, and stasis dermatitis features (hemosiderin, atrophie blanche, lipodermatosclerosis).
• Treating physician RFC form addressing standing, walking, elevation requirements, off-task time for wound care.

Frequently Asked Questions

Bottom line

Listing 4.11 has two paths. Path A is brawny edema at the right anatomic extent. Path B is varicosities plus stasis dermatitis plus an ulcer that either keeps coming back or does not heal after 3 months of adequate treatment. Both paths require documented deep venous system incompetency or obstruction, which is proven by duplex ultrasound.

Most CVI patients do not meet 4.11. Their swelling is pitting, or their ulcer heals in a month, or their deep system is intact. For those cases, the argument shifts to RFC where standing tolerance, elevation requirements, and off-task wound care time can drive a Grid Rules finding of disabled.

Document precisely. Use anatomic landmarks. Measure ulcers. Trial compression for at least 12 weeks before filing on Path B. Get a proper duplex ultrasound. Do these things and the case is winnable at the initial level.
