Personal history of diseases of skin and subcutaneous tissue

This code indicates a patient's past medical history of conditions affecting the skin and the tissue directly beneath it. It signifies that while the patient previously experienced such a disease, they are no longer actively suffering from it at the time of the encounter. This history may be relevant for current treatment decisions or risk assessment.

Use this code when documenting a patient's prior diagnosis of a skin or subcutaneous tissue disorder that has since resolved or is in remission. Examples include a history of severe dermatitis, chronic ulcers that have healed, or a past episode of cellulitis. It is appropriate when the historical condition impacts current care or is noted for informational purposes.

• Do not use this code for current, active skin conditions; instead, code the specific active diagnosis.
• This code is often used as a secondary diagnosis to provide context for current care.
• Ensure documentation clearly states the condition is in the patient's history and not an active problem.
