Personal history of malignant melanoma of skin

This code indicates that a patient has a documented history of malignant melanoma of the skin, meaning they have been diagnosed with and treated for this type of cancer in the past. It signifies that the primary melanoma is no longer present, but the patient remains at risk for recurrence or new primary melanomas.

This code is appropriate for patients who have completed treatment for malignant melanoma of the skin and are now in a surveillance phase. It should be used for follow-up visits, screenings, or when managing other conditions in a patient with a past history of melanoma.

• Do not use this code for active melanoma; instead, use the appropriate C43.- code.
• Always sequence this code after any codes for current conditions being treated.
• Ensure documentation clearly states "history of" or "personal history of" malignant melanoma of the skin.
