I83.012

HCC Category Mapping

What This Code Means

This code describes enlarged, twisted veins in the right leg below the knee that have developed an open sore or wound on the calf. Varicose veins occur when veins don't work properly, causing blood to pool and the veins to enlarge, and in this case the skin has broken down creating an ulcer.

Coding Tips

• •Always verify the laterality (right vs. left) and the specific location of the ulcer (calf, ankle, heel, etc.) from the documentation, as these details are required for accurate code selection
• •Ensure the ulcer is documented as present and related to the varicose veins; if only varicose veins without ulcer exist, use a different code from the I83.0 category

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 right lower extremity
• ✓Specific ulcer location documented (calf) — 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
