Family history of diseases of the skin, subcu

This code indicates a patient's personal history of a family member (e.g., parent, sibling, child) having been diagnosed with a disease affecting the skin or the tissue directly beneath it. This family history is a significant risk factor for the patient developing similar conditions.

Use this code when documenting a patient's increased genetic predisposition to dermatological or subcutaneous tissue disorders due to a familial link. This is often identified during a comprehensive history and physical examination, particularly when evaluating a patient for skin concerns or as part of a preventative health screening.

• Always sequence this code as a secondary diagnosis, as it represents a risk factor, not the primary reason for the encounter.
• Ensure the medical record clearly documents the specific skin or subcutaneous tissue condition present in the family member.
• Do not use this code if the patient themselves has the condition; instead, code the specific skin or subcutaneous tissue disease.
