Non-prs chronic ulc unsp prt of unsp low leg w unsp severity

This code signifies a persistent open sore on the lower leg that is not caused by pressure. It indicates that the specific location on the lower leg and the severity of the ulcer are not documented. This condition typically involves tissue loss extending through the epidermis into the dermis or deeper.

Apply this code when documentation clearly states a chronic lower leg ulcer, but lacks details regarding its specific anatomical site (e.g., calf, ankle) or its severity (e.g., stage 1, stage 2). This code is appropriate when the etiology is confirmed as non-pressure related, but further specificity is unavailable.

• Avoid using this code if any specific anatomical location on the lower leg or severity is documented; instead, query the provider for more detail.
• Always sequence this code after the underlying cause of the ulcer (e.g., venous insufficiency, arterial disease, diabetes) if known.
• Do not use for pressure ulcers; those are classified under the L89 category.
