| Risk Category | Neuropathy | Deformity | History of Ulcer/Amputation | Recommended Visit Frequency |
|---|---|---|---|---|
| Category 0 (Low Risk) | None — protective sensation intact | None | None | Annual podiatric foot exam |
| Category 1 (Moderate Risk) | Loss of protective sensation (LOPS) on monofilament | None | None | Every 6 months |
| Category 2 (High Risk) | LOPS present | Yes — hammertoe, Charcot, bony prominence | None | Every 3–6 months; therapeutic footwear |
| Category 3 (Very High Risk) | LOPS present | Yes | Prior ulcer OR prior amputation | Every 1–3 months; aggressive offloading; wound care team |
| Exam Component | Tool / Method | Abnormal Finding | Clinical Significance |
|---|---|---|---|
| Protective Sensation (LOPS) | 10g Semmes-Weinstein monofilament at 10 plantar sites | Cannot feel filament at 1+ sites | 5.07 monofilament insensitivity = 7x increased ulcer risk |
| Vibration Sense | 128 Hz tuning fork at hallux | Cannot feel vibration or detects <10 sec | Large fiber neuropathy; high fall risk; proprioceptive loss |
| Ankle Reflex | Reflex hammer at Achilles tendon | Absent or diminished bilaterally | Confirms large fiber peripheral neuropathy |
| Vascular Assessment | Dorsalis pedis + posterior tibial pulse palpation; ABI if abnormal | Absent pulses; ABI <0.9 | Peripheral arterial disease — high amputation risk |
| Skin Inspection | Visual exam of all surfaces; interdigital spaces | Callus; fissure; maceration; pre-ulcer; open wound | Pre-ulcer callus is the #1 precursor to ulceration; requires debridement |
| Structural Assessment | Weight-bearing exam; foot pressure mapping | Hammertoe; Charcot; bony prominence; high pressure area | Guides orthotic prescription; deformity correction planning |

Why Diabetes Puts Feet at Risk
Diabetes mellitus affects the feet through two primary mechanisms: peripheral neuropathy (nerve damage) and peripheral arterial disease (reduced blood flow). Neuropathy causes numbness, tingling, and loss of protective sensation — patients literally cannot feel when something is damaging their feet. Vascular disease impairs wound healing by reducing oxygen delivery to injured tissues. Together, these create a dangerous combination where small, unnoticed injuries become serious infections or non-healing ulcers. Diabetes is responsible for more lower extremity amputations than any other cause in the United States.
What Happens During a Diabetic Foot Exam
A comprehensive diabetic foot examination at Balance Foot & Ankle includes neurological testing — using a 10-gram monofilament to assess protective sensation at key points on each foot. Vascular assessment measures pedal pulses and capillary refill time. Dermatologic evaluation identifies skin breakdown, calluses, fissures, and early ulceration. Musculoskeletal assessment documents structural deformities — bunions, hammertoes, Charcot joints — that create pressure points. Nail care for thickened or ingrown nails is performed when needed. Dr. Biernacki documents findings in detail and communicates critical findings to the patient’s primary care physician or endocrinologist.
Risk Classification and Follow-Up Frequency
Not all diabetic patients need the same frequency of foot care. The American Diabetes Association’s risk classification guides follow-up intervals. Low-risk patients with intact sensation, adequate circulation, and no deformities are seen annually. Moderate-risk patients with mild neuropathy or mild vascular disease are seen every 3–6 months. High-risk patients — those with severe neuropathy, vascular disease, foot deformity, or a prior ulcer — are seen every 1–3 months. Patients with active ulcers or infection require urgent, frequent care until resolution.
The Role of Diabetic Footwear
Properly fitted therapeutic footwear is a cornerstone of diabetic foot care. Medicare’s Therapeutic Shoe Bill covers one pair of diabetic shoes and three pairs of custom inserts per year for eligible patients — significantly reducing out-of-pocket costs. Diabetic shoes are designed with extra depth, soft internal construction, and no internal seams that could create pressure points. Combined with custom-molded diabetic insoles, they substantially reduce the risk of ulceration in high-risk patients. Dr. Biernacki prescribes and fits therapeutic footwear as part of comprehensive diabetic care.
Daily Foot Care for Diabetic Patients
Between appointments, diabetic patients should inspect their feet daily — using a mirror or asking a family member to check the soles and between the toes. Wash feet daily in lukewarm (not hot) water and dry thoroughly between the toes. Moisturize dry skin but never between the toes (moisture there promotes fungal infections). Never walk barefoot, even indoors. Report any new blisters, cuts, redness, swelling, or odor to your podiatrist promptly — in diabetes, small problems can escalate to serious infections very quickly.

✅ Pros / Benefits
- Annual exam catches problems before they become amputations
- Medicare covers diabetic shoe benefits for eligible patients
- Comprehensive neuropathy and vascular testing at one visit
- Early intervention dramatically reduces amputation risk
❌ Cons / Risks
- Neuropathy-related foot damage can be asymptomatic until severe
- Vascular disease may require vascular surgery referral
- Daily home foot inspection requires patient commitment
- High-risk patients need very frequent monitoring
Dr. Tom Biernacki’s Recommendation
I’ve prevented amputations that would have happened with just a few more weeks of delay. Diabetic neuropathy is insidious — patients feel nothing while an ulcer is forming under a callus. Annual foot exams find these problems while they’re still simple to fix. Please don’t skip this appointment.

Frequently Asked Questions
How often should diabetics see a podiatrist?
At minimum once per year for low-risk patients. Every 3–6 months for moderate-risk patients with neuropathy or vascular disease. Every 1–3 months for high-risk patients with prior ulcers, severe neuropathy, or Charcot foot.
Does Medicare cover diabetic foot exams?
Medicare Part B covers routine foot care for diabetic patients with systemic conditions affecting the lower limbs. This includes nail care and foot exams when clinical documentation supports medical necessity.
What does a diabetic foot ulcer look like?
Early ulcers may appear as redness, skin breakdown, or a small open sore — often under a callus. Advanced ulcers may show exposed tissue, drainage, or surrounding cellulitis (redness and warmth). Any non-healing skin break in a diabetic patient requires prompt podiatric evaluation.
Can diabetic foot problems be prevented?
Many can. Daily foot inspection, proper footwear, control of blood sugar, and regular podiatric exams dramatically reduce the risk of ulcers and amputation. Prevention is far more effective — and less expensive — than treatment.
