Personal history of diseases of the skin, subcu

This code indicates a patient's past medical history of conditions affecting the skin and the tissue directly beneath it. It signifies that the patient no longer has the active disease but has a documented history of such a condition. This history may be relevant for future treatment planning or risk assessment.

Use this code when a patient presents for a current, unrelated condition, but their medical record documents a resolved skin or subcutaneous tissue disease. Examples include a patient with a history of resolved psoriasis, eczema, or a non-malignant skin lesion that has been successfully treated. It is also appropriate for follow-up visits where the primary reason for the visit is not the skin condition itself, but its history is pertinent.

• Do not use this code for active skin conditions; instead, code the specific current diagnosis.
• Remember the Excludes2 note: do not use this code for a personal history of diabetic foot ulcer.
• Always sequence this code as a secondary diagnosis, as it describes a historical condition, not the primary reason for the encounter.
