L97.918

HCC Category Mapping

What This Code Means

A long-lasting open sore on the right lower leg that is not caused by pressure, with a severity level that doesn't fit standard categories.

Coding Tips

• •Use only when documentation describes a specific severity not captured by other L97.91x codes
• •Ensure the specific severity characteristics are clearly documented

Clinical Significance

This non-pressure chronic ulcer on the unspecified part of right lower leg with other specified severity captures atypical wound presentations that do not fit standard depth classifications, requiring detailed clinical documentation. Chronic non-pressure ulcers are significant for risk adjustment because they indicate ongoing complex wound management needs, increased healthcare utilization, and often reflect underlying systemic conditions such as peripheral vascular disease, diabetes mellitus, or venous insufficiency. Accurate severity coding directly impacts care planning, specialist referral decisions, and appropriate resource allocation for wound care services.

Documentation Requirements

• ✓Confirmation that the ulcer is chronic (present for extended duration, not acute)
• ✓Documentation that the ulcer is NOT caused by pressure (non-pressure etiology)
• ✓Specific anatomical site of the ulcer on the unspecified part of right lower leg
• ✓Laterality documented as right side
• ✓Detailed description of the specific severity characteristics
• ✓Explanation of why standard severity categories (skin, fat, muscle, bone) do not apply
• ✓Clinical rationale for 'other specified' severity designation
• ✓Underlying etiology or contributing conditions (e.g., venous insufficiency, arterial disease, diabetes mellitus, neuropathy)
• ✓Current wound measurements (length, width, depth) and wound bed description
• ✓Current treatment plan and wound care management
