Varicose veins of left lower extremity with ulcer of heel and midfoot

Enlarged veins in the left leg with an open sore on the heel or middle part of the foot. This occurs when varicose veins cause skin breakdown in these specific areas.

Buddy Insight

Varicose veins with ulceration represent a significant complication of chronic venous insufficiency where skin breakdown has occurred due to sustained venous hypertension.

Buddy Documentation Tip

HCC Buddy guidance

Provider documentation of varicose veins with active ulceration of the left lower extremity

Specific ulcer location documented (heel and midfoot) — anatomical site determines code specificity

Description of ulcer characteristics: size, depth, wound bed appearance, drainage, and stage if applicable

Confirmation that the ulcer is a direct complication of the varicose veins (causal relationship)

MEAT Support

Audit Caution

HCC Buddy guidance

Coding the ulcer location incorrectly — the 6th character specifies the anatomical site (thigh, calf, ankle, heel/midfoot, other foot, other lower leg) and must match documentation exactly

Using an unspecified laterality code when left is documented — always capture the specific side

Missing concurrent inflammation that would warrant using the combined ulcer-and-inflammation code (I83.2xx) instead of the ulcer-only code

Failing to assign an additional code for ulcer severity/stage when applicable per coding guidelines

Common Mistakes

HCC Buddy guidance

I83.224 — Varicose veins with BOTH ulcer and inflammation; use when both ulceration and inflammation are documented together

L97.x — Non-pressure chronic ulcer of lower limb; use when the ulcer is NOT caused by varicose veins (different etiology)

I87.2 — Venous insufficiency (chronic/peripheral); use when there is venous insufficiency without varicose veins or ulceration

Verify laterality carefully — do not confuse with right lower extremity codes which have different 5th/6th characters

Is I83.024 an HCC code?

Yes. I83.024 (Varicose veins of left lower extremity with ulcer of heel and midfoot) maps to HCC 383, Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.646. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: I83.024 is billable and maps to V28 HCC 383, Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for I83.024

For I83.024, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means

I83.024 is the ICD-10-CM diagnosis code for varicose veins of left lower extremity with ulcer of heel and midfoot. Enlarged veins in the left leg with an open sore on the heel or middle part of the foot. This occurs when varicose veins cause skin breakdown in these specific areas. I83.024 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified (i80-i89).

Under the CMS-HCC V28 risk adjustment model, I83.024 maps to Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle (HCC 383) with a source-labeled community, non-dual, aged reference coefficient of 0.646. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

Verify documentation specifies the ulcer location as heel and/or midfoot to distinguish from other foot locations. For I83.024, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I83.024 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Verify documentation specifies the ulcer location as heel and/or midfoot to distinguish from other foot locations
•Confirm laterality is documented as left lower extremity; if bilateral, code both sides separately

Clinical Significance

Varicose veins with ulceration represent a significant complication of chronic venous insufficiency where skin breakdown has occurred due to sustained venous hypertension. These venous ulcers are slow-healing wounds that require ongoing wound care, compression therapy, and monitoring for infection. This diagnosis is a high-impact HCC that reflects the increased resource utilization and clinical complexity of managing chronic venous ulceration.

Documentation Requirements

✓Provider documentation of varicose veins with active ulceration of the left lower extremity
✓Specific ulcer location documented (heel and midfoot) — anatomical site determines code specificity
✓Description of ulcer characteristics: size, depth, wound bed appearance, drainage, and stage if applicable
✓Confirmation that the ulcer is a direct complication of the varicose veins (causal relationship)
✓Current wound care treatment plan and any changes in management
✓Assessment for signs of inflammation, infection, or cellulitis which would require additional or different codes

Commonly Confused Codes

•I83.224: Varicose veins with BOTH ulcer and inflammation; use when both ulceration and inflammation are documented together
•L97.x: Non-pressure chronic ulcer of lower limb; use when the ulcer is NOT caused by varicose veins (different etiology)
•I87.2: Venous insufficiency (chronic/peripheral); use when there is venous insufficiency without varicose veins or ulceration
•Verify laterality carefully: do not confuse with right lower extremity codes which have different 5th/6th characters
•L89.x: Pressure ulcer codes; distinguish from venous stasis ulcers which are caused by varicose veins, not prolonged pressure
