Malignant melanoma of unspecified part of face

This code signifies a cancerous tumor originating from melanocytes, specifically located on the face, but without further specification of the exact facial subsite. Malignant melanoma is an aggressive form of skin cancer with a high potential for metastasis if not detected and treated early.

Use this code when documentation confirms a diagnosis of malignant melanoma on the face, but the specific anatomical location (e.g., eyelid, nose, lip, ear) is not precisely identified. This code is appropriate when the provider's notes state "malignant melanoma of face, unspecified" or similar.

• Avoid using this code if a more specific facial subsite is documented; always strive for the highest level of specificity.
• Review pathology reports carefully for definitive diagnosis and anatomical detail.
• Always code the primary malignancy first, followed by any secondary malignancies or other relevant conditions.
