0.000What This Code Means
A long-lasting open sore on the right calf that is not caused by pressure, with dead bone tissue present.
Coding Tips
- •Requires explicit documentation of bone necrosis in the clinical record
- •Distinguish from L97.216 which involves bone without necrosis
Clinical Significance
Non-pressure chronic ulcers of the lower extremity are significant indicators of underlying vascular disease, diabetes, or other systemic conditions that impair wound healing. Bone necrosis represents the most severe stage of chronic ulceration with osteomyelitis risk, frequently necessitating aggressive surgical intervention and reflecting profound underlying disease burden.
Documentation Requirements
- ✓Ulcer site documented as right calf with clear laterality (right side)
- ✓Confirmation that the ulcer is chronic (present for extended duration, not acute)
- ✓Etiology documented as non-pressure (e.g., venous stasis, arterial insufficiency, diabetic, or other non-pressure cause)
- ✓Clinical assessment of wound depth and tissue involvement
- ✓Documentation of necrotic bone within or at the base of the wound
- ✓Imaging or clinical findings confirming bone necrosis (osteonecrosis)
- ✓Assessment for osteomyelitis with appropriate workup (imaging, labs, culture if indicated)
- ✓Surgical consultation documentation if applicable
Commonly Confused Codes
L97.213 — necrosis of muscle; muscle tissue death is presentL97.216 — bone involvement without necrosis; bone exposed but viable, no necrosisL97.114 — left calf; verify laterality before selecting codeL89.- — Pressure ulcer codes; use only when ulcer is caused by sustained pressure, not vascular or other non-pressure etiology
