Non-prs chronic ulcer oth prt right foot w fat layer exposed

This code signifies a persistent, open sore on the right foot, excluding the heel or toes, that is not caused by pressure and has progressed to expose the subcutaneous fat layer. This type of ulcer often results from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation specifies a non-pressure chronic ulcer located on an unspecified part of the right foot (e.g., dorsum, plantar arch) with involvement down to the fat layer. Supporting documentation should clearly indicate chronicity, the non-pressure etiology, and the depth of tissue involvement.

• Always confirm the laterality (right foot) and the specific location on the foot to differentiate from other L97 codes.
• Ensure the documentation explicitly states "non-pressure" to avoid confusion with pressure ulcers (L89.xx).
• Verify the depth of tissue involvement; this code is specific to fat layer exposure. Deeper involvement (muscle, bone) would require a different code.
