L97.823
BillableNon-pressure chronic ulcer of other part of left lower leg with necrosis of muscle
HCC Category Mapping
What This Code Means
A long-lasting open wound on the left lower leg (not from pressure) where the muscle tissue has died and deteriorated.
Coding Tips
- •This is the left-sided equivalent of L97.813; document evidence of muscle necrosis clearly
- •Indicates significant tissue damage requiring specialized wound care
Clinical Significance
This non-pressure chronic ulcer on the other part of left lower leg with muscle necrosis represents severe tissue destruction where dead muscle tissue creates a nidus for infection and significantly impairs wound healing potential. 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 other part of left lower leg
- ✓Laterality documented as left side
- ✓Clinical documentation of muscle tissue necrosis (dead/devitalized muscle)
- ✓Wound assessment confirming depth extends to muscle layer
- ✓Description of necrotic tissue characteristics (color, texture, odor)
- ✓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
