What This Code Means

A long-lasting open sore on the left foot (not from pressure) that has reached the bone but shows no dead tissue.

Coding Tips

•Bone involvement is present but viable; distinguish from L97.524 (bone necrosis)
•Confirm location is 'other part' of left foot and non-pressure etiology

Clinical Significance

This non-pressure chronic ulcer on the other part of left foot with viable bone involvement indicates the ulcer has reached bone without causing osteonecrosis, representing a critical window where intervention may prevent bone death. 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 foot
✓Laterality documented as left side
✓Wound assessment confirming bone involvement/exposure
✓Explicit documentation that bone is viable (no necrosis present)
✓Imaging studies confirming bone involvement without osteonecrosis
✓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

Commonly Confused Codes

L97.516 — Right foot equivalent; verify laterality documentation carefully L97.524 — bone necrosis — this code requires necrosis (tissue death) to be present L97.525 — muscle involvement without necrosis — less deep, does not involve bone L89.xxx — Pressure ulcer codes; L97 is specifically for NON-pressure chronic ulcers L97.8xx — Lower leg ulcer codes; verify whether the ulcer is on the foot or leg
