Non-prs chronic ulcer of unsp heel/midft with oth severity

This code describes a chronic ulcer on the heel or midfoot that is not caused by pressure. The severity of the ulcer is documented as something other than mild, with or without necrosis, or unspecified. This indicates a persistent wound in these specific foot areas, excluding those resulting from sustained pressure.

Use this code when documentation specifies a non-pressure chronic ulcer located on the heel or midfoot, and the severity is described as something other than mild, or is unspecified. This applies to conditions like venous stasis ulcers, arterial ulcers, or diabetic ulcers affecting these areas, where the specific severity (e.g., with granulation tissue, with fat layer exposed) is noted but doesn't fit the "mild" category. Documentation should clearly state the etiology is non-pressure and specify the location as heel or midfoot.

• Ensure the documentation explicitly states the ulcer is not pressure-related. If pressure is the cause, a pressure ulcer code (L89.-) should be used.
• This code is for an unspecified heel or midfoot location. If the specific heel (right/left) or midfoot (right/left) is documented, a more specific code (L97.41- or L97.42-) should be chosen.
• Always code the underlying condition (e.g., diabetes mellitus, peripheral artery disease, chronic venous insufficiency) first, followed by this ulcer code.
