Non-prs chronic ulcer oth prt unsp low leg with oth severity

This code signifies a chronic ulcer on an unspecified part of the lower leg, excluding those caused by pressure. The ulcer's severity is documented as "other specified," indicating it doesn't fit into the typical stages (e.g., unspecified, muscle necrosis, bone necrosis). This diagnosis points to a persistent skin breakdown requiring ongoing management.

Use this code when documentation clearly indicates a non-pressure chronic ulcer located on the lower leg, and the physician has specified a severity that is not one of the standard stages. This is appropriate for ulcers due to venous insufficiency, arterial disease, or neuropathic causes, where the specific severity is documented but doesn't align with the more granular L97.xxx codes.

• Ensure the documentation explicitly states "non-pressure" and identifies the lower leg as the site.
• Verify that the severity is described as "other specified" and not an unstageable, muscle, or bone necrosis severity.
• Always sequence this code after any underlying systemic condition (e.g., diabetes, peripheral artery disease) contributing to the ulcer formation.
