Non-prs chr ulc of l heel/midft w bne invl w/o evd of necr

This code signifies a persistent ulceration on the left heel or midfoot that is not caused by pressure. The ulcer has progressed to involve the underlying bone structure but does not exhibit signs of necrotic tissue. This indicates a deep, chronic wound with significant tissue destruction.

Apply this code when documentation specifies a non-pressure chronic ulcer located on the left heel or midfoot, with clear evidence of bone involvement confirmed by imaging or surgical findings. The absence of necrosis must also be explicitly stated. This code is appropriate for conditions like diabetic foot ulcers or venous stasis ulcers that have eroded to the bone.

• Ensure documentation explicitly states "non-pressure" and specifies "left heel and midfoot."
• Confirm bone involvement is documented, often through X-ray, MRI, or operative reports.
• Verify the absence of necrosis; if necrosis is present, a different code from the L97.42- series would be more appropriate.
