Malignant melanoma of other specified sites of skin

This code signifies a cancerous tumor originating from melanocytes, specifically located on skin sites not otherwise classified as trunk, limb, face, scalp, or ear. It indicates a primary malignant melanoma found on less common or multiple specified skin areas.

Apply this code when documentation clearly specifies a primary malignant melanoma of the skin located on sites such as the neck, groin, or multiple non-contiguous specified skin areas. Supporting pathology reports confirming melanoma and physician notes detailing the exact anatomical location are essential.

• Ensure the documentation specifies a primary melanoma; metastatic melanoma to the skin would be coded differently.
• Carefully review the physician's notes for precise anatomical location to differentiate from more specific melanoma codes (e.g., face, trunk, limb).
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
